BONE Structure


The BONE-project is structured in 6 Virtual Centres of Excellence and 7 Topical projects. Centralised activites are grouped in 4 General Workpackages dealing with management, dissemination, teaching and electronic tools. All these workpackages are outlined here and the specific objectives can be reached by clicking on teh name of teh workpackage below.

Centralised activities

Some of the activities within the BONE project are defined to support the general working of the project or centralise the dissemination & teaching activities.

Virtual Centres of Excellence

The BONE-proposal proposes to solidify the current e-Photon/ONe network and has the objective to provide a limited number of Virtual Centres of Excellence on specific issues:

These Virtual Centres of Excellence group, align and (re-)structure the research activities of the BONE-partners involved in such a way that a coherent solution and service can be offered to BONE internal and external partners and projects.

Topical Projects

Hot and multidisciplinary topics and issues are handled and looked at through a limited number of Topical Projects which each have a limited duration. These Topical Projects are either horizontal projects which make use of the expertise available at different Virtual Centres of Excellence or tackle specific issues to fill in specific needs or gaps in the expertise of the Virtual Centres of Excellence:



Centralised activities

WP01: Dissemination & Outreach

WP01 is the workpackage in charge of disseminating the information, technical results and scientific work progress of the Network, both within the consortium itself and also with external parties involved in the area of optical networking, with the objective of facilitating the smooth integration and spreading of excellence. More specific objectives of the Dissemination and Outreach activities are the following:

  • To disseminate information concerning the expertise, research and integration activities of the Network of Excellence and spread excellence to other European researchers and their institutions.
  • To reach out to the European communities and young researchers and explain the purpose and challenges of optical networking and how the Network of Excellence can support local initiatives in this area.
  • To facilitate the integration of a strong collaborative institution framework, to allow expert groups to effectively collaborate within the Network on key topics.
  • To extend the roadmap [commenced in e-Photon/ONe] into a focused view (roadmap) of the evolution of photonic networks [within Europe] for telecom and non-telecom applications; and bench mark European research activities against international programmes.

The high level of technical excellence of each partner in the consortium enables WP01 to focus on and support methods for the dissemination of their research, which in turn promotes integration. The variety of topics covered by the various workpackages makes this an interesting and challenging task to accomplish, but the strong collaborative framework that has been established within the consortium that comprises a community of its own, assists greatly in the dissemination of knowledge across the consortium. As far as external parties are concerned these mainly comprise:

  • European institutes outside the consortium where it is felt that contact should be established,
  • industry in the area of optical communications where ties for mutual interactions are being established,
  • international institutes,
  • other IST and ICT projects with similar or complementary scope, and
  • outreach to younger generations of pupils/students to raise awareness of optical networking. Hence the dissemination activities target the consortium itself and the five groups mentioned here.

Six types of Dissemination and Outreach activities are available in BONE, namely:

  1. Workshops and conferences and events either supported or organized by the consortium; exhibition booths are also included.
  2. Preparation of dissemination material (posters, presentations and flyers). This material was made available to be used in different types of events.
  3. The organization of a Schools public event.
  4. The development of a Roadmap.
  5. Online dissemination
  6. The formation of a Think-Tank to communicate specific issues with the industry.

WP02: Teaching

The main objective of this WP is spreading excellence within and outside the project through the organization and execution of teaching activities based upon a common Master program in Optical Communications and Networks, combining benefits of teaching in situ, teleteaching, and application of learning tools. These activities will be mainly based upon the Master Curriculum and supporting teaching materials created within the previous e-Photon/ONe project. The objectives are:

  • to offer courses of the Master to students within BONE summer/winter schools;
  • to create teaching materials for Master studies with license for open access. The materials will consist of presentation slides, support materials and video lessons. All materials will be stored on the project web site;
  • to prepare a report on the opportunities and obstacles of offering permanent Master teaching across a number of partner institutions;
  • to encourage other types of knowledge dissemination, stimulating exchange of teaching materials, video lessons, lecturers and students;
  • application of advanced techniques for spreading knowledge: distribution of video lessons and learning tools, as well as teleteaching;
  • to improve curriculum and teaching materials according to the feedback from course execution For all the objectives listed, special attention will be paid to include dissemination towards the New Member States.

WP03: Electronic Communication Aid

The main objective of the activities within WP03 is to provide the consortium with a set of useful electronic tools aimed at simplifying communications among partner, promoting integration and disseminating the NoE knowledge-base to the international research community. The electronic communication tools to be deployed will include a website, an electronic directory and reporting service, a mailing list system, a click-to-talk VoIP service, a shared workspace to be used for discussions and document sharing.


Virtual Centres of Excellence

WP11: VCE on Network Technologies and Engineering.

Although optical transmission dominates telecommunication networks, optical networking is in many respects still in its infancy. Current networks comprise primarily point-to-point optical connections, whereas all network functionality is being carried out outside the optical domain. Reconfigurable optical add-drop multiplexers are just emerging in the market and optical cross connects are available but not quite employed as yet. Therefore research on optical networking technologies is still a lively and up to date field, with the main goal to provide solutions and effective evolutionary paths to make all-optical networks to become reality. This is especially true now that a renewed interest in optical networking is motivated by the emergence of very bandwidth demanding applications, today confined to specific niches usually related to scientific research, but that can indeed be considered a glimpse of future networking scenarios.

Besides pure feasibility issues, one of the questions to be answered is in which sections of future networks the optical technologies would provide more advantages and adapt best. Telecommunication networks can be seen as divided in areas depending on their proximity to the end user and/or the degree of aggregation and/or the physical size. An access part connects the end-user to some sort of aggregation point from which the aggregated traffic is forwarded to the inner parts of the network. This VCE does not address the access part, but rather the rest of the transport network and focuses on optical network technologies, solutions and network elements, however not addressing transmission issues.

In general it is assumed that end-user applications or terminals traverse some sort of aggregation network that is then interconnected with the core network. The first and second aggregation levels may for example be a local network, a metropolitan area network, or a regional network. The exact architecture depends on legacy, topology, traffic etc.

The main objective of the WP is the integration of the research activities on technologies for all optical networking in the metro and core networks. Integration will be achieved by adjusting the focus of research on similar or overlapping topics, by extending the scope of existing activities as well as by promoting new joint research activities on topics that are not covered by single partners.

WP12: VCE on Services and Applications

Broadband-for-all is meant to satisfy the needs of future mass market bandwidth-greedy customer applications, such as High definition TV, Storage, Grid-based distributed computing, or Peer-to-peer. Indeed these applications will require advanced network services, such as Virtual Private Networks (VPN), with strict requirements in terms of bandwidth, latency and resilience. In addition, whenever these applications operate in a Wide Area Network (WAN), issues regarding the security, the provisioning approach, the discovery and the network service monitoring arise. Typically these applications will also manipulate, exploit or deploy non-network resources such as raw data, computing capability or temporary storage space. From this perspective, these applications will require visibility and availability of non network services, and especially for the latter some new extended features will also be required (security, provisioning, monitoring, discovery).

The above scenario applies to the access, metro and core segments of traditional telecom operator metro segments that are more and more required to offer added-value services rather than pure connectivity sockets.

The Virtual Center of Excellence on Services and applications is focused on the definition of a roadmap

  1. for conceptually characterizing the service access problem both at the customer application side and at the network side (through all segments)
  2. for identifying and structuring network services in terms of VPN to fulfil the bandwidth and level of connectivity needed by applications,
  3. for identifying and structuring non-network services as perceived by a customer application
  4. for restructuring the business chain of telecommunications between transport providers (i.e. network service providers) dealing with network resources and service providers dealing with non-network resources.

With this aim, specific objectives of this WP are:

  • To integrate the research efforts on applications and services in Europe with special emphasis on those based on optical networks.
  • To collect inputs and research outcomes for preparing guidelines of the most appropriate approaches for the application-to-network interaction to be offered to European providers and vendors
  • To investigated on service platform architectures that apply to the various network segments handled by telecom operators
  • To define roadmaps for the evolution of the telecommunication business in terms of services based on network and non network resources.

Within this VCE, there is a need for competence in protocols for the control and management plane of optical networks, software technology for network elements, distributed system architectures, interfaces for improving interoperability, etc. The activities of this VCE will be synergic with other WP of the BONE proposal (in particular WP21, WP22 WP26 and possibly WP11 and WP14) as well as with other FP7 project in preparation such as CORONA and REACTION.

WP13: VCE on Access Networks

Broadband-for-all still constitutes a key objective in the European information society and is, for the most part, far from a reality for most citizens. Its implementation depends on major investments and the cost effectiveness of new technologies based on optical access, which must also demonstrate a future-proofed solution to avoid any kind of communication bottleneck and seamlessly support innovative new services in the long term. It is clear that although a lead has been taken in deep fiber deployment in Asia, Europe is well placed to take a strategic position in this field. In this area where geographic, demographic and economic issues must be considered in tandem with technological studies the wide range of expertise within Europe offers the potential for a position of strength in this important research topic. In particular, it is seen as vital that the current proliferation of propriety technologies is successfully integrated in technical standards that are based on sound scientific and commercial evaluations. To meet these challenges, BONE has specifically focused a Virtual Centre of Excellence on Access (VCE-A)

This Virtual Centre of Excellence on Access will aim to provide a forum for exchange and consolidation of the latest research and development on access systems that use optics to provide true-broadband connections to fixed and mobile users. Different technologies like new TDM-PONs, WDM-PONs, Radio-over-Fibre, Free-Space-Optics or xDSL-overfibre are being developed and are competing in diverse scenarios.

With this aim, specific objectives of this WP are:

  • To integrate the research efforts on broadband access in Europe.
  • To establish a benchmarking platform for the different optical access technologies, to provide a series of guidelines for the deployment of most promising and effective access techniques in the different scenarios in Europe.
  • Provide insight into the integration of access technologies to provide operators with cost-effective evolution paths for the introduction of new services.
  • Document and make available to all test-bed and platforms.
  • Contribute to standards in the area, both within Europe and externally.

Due to the fast pace of these technologies and the changing landscape of the Access market, both these key objective and the routes to their fulfilment will evaluated and, if necessary, adjusted yearly. Through these evaluation exercises it is likely that proposals for new topical projects (TPs) will be generated. In addition it is expected that this VCE will act as a spawning ground for new research activities which will be developed for future FP7 funding calls or through other funding sources.

The activities of this VCE will be synergic with other WP of the BONE proposal, in particular we will contribute to WP01 Dissemination & Outreach, WP15 VCE Transmission techniques, WP16 VCE Transmission techniques, TP Optical communication networks in support of user mobility and networks in motion and TP edge-to-node adaptation for hybrid networks. In addition this activity is likely to support other FP7 project in preparation such as FIMOBA and dinamicWDMPON

WP14: VCE on Optical Switching Systems

The prime objective of the Virtual Centre of Excellence on Optical switching systems (VCE-S) work package is to craft R&D directions and define the position of photonic switching in future optical networks. R&D actions must be aligned with current technologies and system perspectives for the future internet. Current development and emerging applications command the design of highly dynamic optical networks where capacity is allocated “on demand” and “on the fly”, when needed, where needed. Optical switching constitutes a separate network service and as such it must be provisioned, protected and/or restored when needed.

Recent technology development has unlocked most of the fiber capacity making capacity an abundant resource. However, the majority of WDM deployment has occurred in the form of point-to-point links with amplifiers in between as needed. Optical WDM lightpaths are static and is seen as a scarce resource. Once set up, they remain in place, essentially forever. It is therefore only switching that transforms the raw bit rates into useful bandwidth. The questions that rise are how and where photonic switching is positioned in future internet and which problems must be solved to reach this goal. We argue that optical switching can provide the technologies needed for:

  • Designing an intelligent, service-aware data plane and offer new switching functions to support a wide diversity of service attributes and requirements.
  • Converging heterogeneous network infrastructures including legacy point-to-point designs, transparent or semitransparent network topologies.
  • Interconnecting broadband wireless networks eliminating the barriers to broadband access and guaranteeing high speed end to end connectivity.
  • Designing large terabit-capacity but low power consuming switch fabrics including state-of-art component technology.
  • Protecting critical infrastructure resources.
  • Optimally controlling, highly flexible and highly dynamic network infrastructure that can be self-organized to allocate on the fly bandwidth to (bandwidth hungry) end users.

Optical switching provides solutions to the above mentioned issues to overcome the expected long term limitations of current internet infrastructure, driven by the need for: generalized mobility; dynamic resource allocation and scalability from the perspective of network and service design. These entail addressing the evolution from today's large legacy infrastructures towards new infrastructures by striking a balance between backward compatibility requirements and the need to explore disruptive optical switching functions. The incentive is to use optical switching to make spectrum efficient in terms of switching and not in terms of only capacity.

WP15: VCE on Transmission Techniques:

Optical high-speed transmission is a fundamental aspect of optical networking. It is a key prerequisite and enabler of future broadband networks and greatly affects switching, architectural and even protocol evolution and progress. This is why, within BONE, optical transmission has been devoted a specific Virtual Center of Excellence, called VCE-T.

VCE-T aims at promoting, fostering, stimulating and coordinating the research activity of those BONE researchers whose primary field of expertise is optical transmission. At the same time, it also aims at harmonizing such activities with research carried out within other VCEs in BONE, regarding higher network layers.

To reach these goals, along the life of the NoE, VCE-T is expected to

  • reach consensus on key research issues in “Transmission Techniques” for the Network of the Future and accordingly
  • promote the set-up of collaborative research on such issues among VCE-T partners. In this respect, it will build upon the considerable and very valuable expertise accumulated within the projects e-Photon/ONe and e- Photon/ONe+.

VCE-T will also coalesce, organize and directly coordinate specific research projects, potentially addressing transmission issues across all the optical networking segments, from core to metro, all the way down to short-reach networks. If such projects reached a critical mass of partners, VCE-T plans to spawn them in the form of separate TPs, in coordination with all the other relevant VCEs.

Among the several important topics that will be of great relevance for the Network of the Future, three key ones are identified:

  • 100Gb/s: Reliable, resilient 100 Gb/s (per channel) Ultra-Dense WDM transmission, backward-compatible with the existing infrastructure
  • Mitigation: Mitigation of transmission impairments by transmitter, in-line, and/or receiver-based advanced optical or electronic signal processing and coding techniques
  • Monitoring: Distributed channel and network performance monitoring and overall transmission layer supervision

Over the course of the three-year project, these key objectives will be re-evaluated, at least yearly. It is highly likely that adjustments will have to be made and perhaps new key topics will arise. The consensus-forming activity needed to keep up with technical progress in the field, as well as changing scenarios, is one of the main objectives of VCE-T. It will be carried out at plenary meetings, through technical workshops and by means of constant information exchange among partners.

Once a new topic has been identified which deserves to be turned into a cooperative project, VCE-T will adopt it. If any topic reaches a critical mass of interest and number of committed partners, the spawning of a TP will be proposed to the BONE JPAC.

WP16: VCE In-building Networks:

The major objective of this VCE is to align the research activities on architectures and techniques for optical in-building networks. After having reached the doorstep of buildings (homes, office buildings, hospitals, etc.), optical fibre techniques’ next challenge is to bring real broadband communication inside the buildings. A single optical fibre infrastructure should support a wide range of services, both wired and wireless ones, from low to ultra-high bandwidths, and with various QoS demands, all of this of course at very low cost.

More specifically, the objectives of this WP are:

  • To co-ordinate and integrate the research efforts on in-building networks deploying optical communication techniques in Europe, by exchanging researchers, jointly performing research and laboratory experiments, joint publications, etc.
  • To establish benchmarking platforms for the different optical in-building technologies,
  • To provide guidelines for the roll-out and deployment of optical in-building networks, including migration paths.


Topical Projects

Study how the optical architectures can be exploited and enhanced to realise service oriented architectures. This will in particular include the study of:

  • both the user centric and network centric approach;
  • various aspects, e.g. signaling schemes, optimisation of resources, routing algorithms, end-to-end QoS, testing through simulation

WP22: TP on MPLS, GMPLS and routing.

This workpackage addresses key research aspects in the evolution of IP-MPLS multi-service networks to all-optical. In particular:

  • GMPLS/MPLS/IP integration & migration issues: impact on design, control and management schemes for IPdriven next-generation optical networks. Performance evaluation, protection and restoration.

WP23: TP on Optical communication networks in support of user mobility and Networks in Motion

Within the next few years, networks in motion will play a central role in the people’s lives, worldwide. An upcoming networking concept is emerging based mainly on the requirements of mobile working groups of people of various societal sectors that demand ubiquitous connectivity. The individual subscribers themselves will increasingly carry around their own short-range personal network which is constituted when networked personal devices interconnect and create a Personal Area Network (PAN).

Many groups of users exist who follow a slowly or a fast mobility pattern and therefore access on mobile vehicles (car, train, airplane) or just to people moving on foot becomes a necessity. The moving networks often need to communicate with each other or the outside world, resulting in a unique new form of network namely the “network in motion”. Thus the surrounding infrastructure needs to be able to support a large amount of personal network connections. For such new application scenarios, it is critical that the next generation of networks employs intelligent components and devices that in a way sense the user needs and are able to provide guaranteed content delivery in an efficient and secure manner (while providing the privacy of the communication). For such a system to run successfully, intensive research must be done. Particularly, the use of optical network solutions in the aggregation and core part of the network is essential and requires extensive research in the both the networking and technology areas.

This work package is focusing on providing collaborative research towards three main directions identified in the following objectives:

  • To perform studies on intelligent technologies and design challenges for wireless access in networks in motion (e.g. based on RoF, FSO, or conventional wireless solutions with optical fibre feed)
  • To perform studies on networking properties and switching characteristics for the aggregation and core networks in support of networks in motion (e.g. Switched Ethernet based solutions or advance schemes like OBS/OPS),
  • Development of control plane and signalling algorithms and protocols for networks in motion (e.g. MAC layer design or network layer approaches with QoS quarantines, resource reservation approaches etc.)

WP24: Topical Project on Edge-to-core adaptation for hybrid networks

This workpackage aims at addressing the various issues that concern edge-to-node adaptation in hybrid networks. More specifically, the following topics are included:

  • Optical Burst Switching: burstification, TCP over OBS, edge node analysis.
  • The impact of OBS/OPS on upper layer protocols (TCP, SCTP, ...)
  • Optical Packet Switching: adaptation issues, packetization, traffic shaping asynchronous-synchronous.
  • Physical layer issues: transmission of optical bursts.
  • Multicasting in subwavelength granularity networks: traffic grooming at the edges
  • Polymorphic networks: comparison between Optical Burst/Packet Switching and Optical Circuit Switching
  • Traffic models

WP25: TP on Optical Interconnects

The Topical Project on Optical Interconnects (TP-OI) is specifically aimed at studying the design methodologies of photonic backplanes in multi-service switching nodes.

Multi-service switching systems, operating at several network layers and interconnecting different types of interfaces with different granularities, are becoming favourite vendor top-line-products to meet operator needs of simplifying network architectures and of implementing advanced control-plane techniques (ASTN, GMPLS, ASON). Electrical wiring between the modules of these high-capacity switches sets severe bounds to their performance. In this scenario photonics appears to be a promising and effective solution to interconnect switching-node subsystems. Optical interconnection technology is evolving very rapidly in recent times, with interesting new developments in devices and transmission (e.g. VCSEL, MEMS, high-contrast-ratio waveguides). This is witnessed by the peculiar renewed interest of the major switching-equipment vendors towards optical-interconnect solutions.

In this framework a specific research activity dedicated to optical-interconnection architectures for switching nodes appears well motivated and strategic. The application of optical interconnections within electronic is a rather new and relatively unexplored research field. Bringing photonics “inside-the-box” can have a relevant impact on interconnection topologies and architectures (the so called “backplane”) of switching-nodes subsystems. Studying how optics can be simply used to replace electrical wiring for fixed point-to-point links is per-se an interesting topic, but it can be regarded as a first step. The theme gets much more challenging if the designer tries to exploit also optical-signal switching capability seeking for new, more efficient and reliable backplane architectures.

This project studies the optical implementation of the interconnection systems “inside the box”. The target is to develop the capability to design and optimize an optical backplane, finding the technology and architecture best-fitting system requirements. Intermediate steps comprise: physical-layer design, architectural studies, network simulation, traffic characterization.

The main outcome of this project will be the delivering of one or more complete designs of optical backplanes. On the way to this final achievement, however, several “by-product” results are expected. For example, short-range optical transmission systems with ultra-wide bandwidth (100 Gbit/s or above) will be studied and designed.

Dissemination of results of the project will be actively sought in terms of conference and journal publications, though in a way respectful of possible intellectual-property rights and obligations of contributing partners.

In the project, knowledge from different fields will be integrated: photonic device technology, optical transmission and propagation, optical networking, photonic switching-systems, switching-system theory. Network-design approaches well-developed in the past for geographical and local-area networks will also be used, suitably adapting them to the specific “microscopic” context of a switching-node. The broad range of know-how will be exploited in covering different aspects of the main theme, including: physical design and performance evaluation; interconnection topology design; system resilience, survivability and reliability evaluation; “inside-the-box” routing and scheduling algorithms; analysis of traffic requirements; traffic simulation and performance evaluation; control and signalling techniques.

The contributing partners will bring their strong background in some of the above fields. The project will then make use of expertise developed in the following Virtual Centres of Excellence: WP11 for multi-service switching-node requirement definition, WP14 for optical interconnection architectures, VP15 for physical design and implementations.

WP26 – TP on Alternatives for multi-layer networking with cross-layer optimization

Dynamically reconfigurable optical networks that offer cost-efficient use of bandwidth will form the basis of future next generation networks’ data oriented core. Future Internet approaches consider the efficient transport of data traffic over Optical Transport Network (OTN) protocols or even over more futuristic approaches like Optical Burst Switching and Optical Packet Switching. In general, these solutions are focusing on methods for converged data traffic (IP, Ethernet) over optical networking solutions forming finally ‘multi-layer’ networks.

The various architectures and protocols proposed in this direction should consider networking performance, complexity and implementation cost issues. However, depending on the convergence approach that these solutions try to adopt, networking studies on different multi-layer network architectures and approaches are essential for the identification of optimum solutions in terms of capacity, network topology, traffic model etc.

Moreover, a number of architectural and technology challenges associated with the operation of a multi-layer network environments exist, especially when considering new transparency challenges. In such networks guaranteed QoS provisioning becomes very challenging as advanced monitoring techniques are required combined with efficient information dissemination protocols able to handle the rapid traffic variations and meet fast reconfiguration times at the nodes. In this concept, multi-layer transparent optical networks require the examination of novel schemes and the development of certain algorithms that can take into account the characteristics of the underlying layers. Cross-layer optimization methods must take into consideration both higher layer traffic characteristics and lower layer switching capabilities in order to provide efficient solutions and protocols for the realization of multi-layer networks.

According to this the two main directions that this targeted work-package focuses are:

  • Multi-layer approaches (architectures, protocols and network characteristics) for future Internet Protocol (or Ethernet) convergence over optical network solutions
  • Cross-layer optimization approaches that take into consideration the physical layer, transport/data link layer and network layer characteristics.

The specific objectives for each of the aforementioned foci are:

  • For the studies on multi-layer approaches
    • Identification of various solutions for converged IP over optical networks and the networking issues related to each solution
    • Identification of the networking parameters that must be taken into consideration when examining the performance of multi-layer networks.
    • Examination of modelling challenges related to the multi-layer networking simulations
    • Development of performance evaluation tools for various multi-layer network solutions
  • For the studies on cross-layer optimization
    • Identification of the lower layer parameters (e.g. physical impairments, resources availability etc) that can be offered and monitoring methods to collect and disseminate this information to the network.
    • Identification of higher layer parameters (e.g. QoS requirements, traffic demands etc.) and ways that these can be included in the development of fast reconfiguration algorithms
    • Development of cross-layer optimization schemes
    • Performance evaluation and feasibility studies.

WP27 - TP Physical Impairments constrain based routing in packet switching networks

This project focuses on the determination of the possible strategies for implementing impairment constrains based routing (ICBR) in packet switching networks. These strategies will make the new packet oriented networks able to cope with several dynamic and impairment agnostic changes in the network length, topology or vendor. If the network can survive different accumulated impairments by recognising them, the interfacing with unknown networks and the changes in the networks will be handled simply and in a robust way.

As it is well known, as the data blocks become smaller (circuit->burst->packet), and the data rates become progressively higher, the handling the network becomes more and more complex, limiting the application of several of the current protocols and techniques. One specific case relates routing, and impairments consideration in its strategies.

As what regards, ICBR, there are several factors which should and can be considered in a general strategy, however, several are, which can be considered at router level increasing the effectiveness of the routing strategy. One may consider that effective degradation of the packet due to any physical or security level impairment can be considered at the level of the router, however the general strategy can and should be decided at the level of the network management. Of course, these two examples, being only examples, are ruled by different time scales, at router level packet by packet decision, and at the management level, only the general strategy should be considered.


The work to be performed within this project is related to the determination of:

  • Routing decisions which could/should be taken at router level and which of them at management layer level.
  • Techniques can be used for implementing the packet by packet impairment/security constrain based directives.

The results of this topical project will be:

  • Directives for implementing packet switching constrained based routing
    • Group of parameters eligible to be taken as primary at the level of the low speed CBR
    • Group of parameters eligible to be taken as primary at the level of the router and therefore at packet level.
  • Identification of all-optical techniques which can be applied all-optically to the packets in order to help routing at router level (e.g. discard, regeneration, etc)
