The NOBEL project was createdfrom the aggregation of four EoIs

IHCON

FlexNet

Negosan FutureNetworks

Telecom Italia Alcatel

Lucent BT

…starting from the FP5 projects achievements

• What is needed to deploy network solutions for “Broadband for All”?– There are two major bottlenecks:

• “last mile”• “core/metro end-to-end networking”

Motivations (1/2)

5

• What are Customers’ requirements ?• More bandwidth at lower costs• Flexible selection of service provider• On-demand bandwidth requests (e.g. Bandwidth on Demand)• Configurable connectivity (e.g. for Optical VPN)• Different levels of SLA

• What are Providers’ requirements ?• Optimised solutions that reduce CAPEX and OPEX :• Fast and simple provisioning• Simplified interworking with other providers • Scalability to a large number of Customers• Different levels of QoS and survivability strategies

Motivations (2/2)

NOBEL main objectives

• To define drivers, requirements, scenarios, architecture and solutions for core and metro optical networks

• To study advanced traffic engineering and resilience techniques

• To make techno- and socio-economic analysis

• To identify solutions for advanced packet/burst switching

• To define solutions for network management and control

• To identify solutions and technologies for physical transmission

• To define multi-service/multi-layer node architectures and to prototype the implementation of selected node functionalities

• To assess existing technologies, components and sub-systems

• To integrate a main test bed and to start validating project results with experimental activities

11

NOBEL expected results• Network Concepts, Requirements and Social Impact

• Innovative solutions for end-to-end services in metro/core networks (solving the open problems)

• Social and techno-economic evaluations of services and network concepts

• Transport nodes, network management and control• Strategies for the end-to-end QoS, management and control

• Transmission and physical solutions for metro/core networks identifying optimal balance of packet/burst/circuit switching

• Feasibility studies and prototype realizations of advanced functionalities in multi-service / multi-layer nodes

• Enabling technologies and test-bed/field-trial integration• Identify existing technologies for cost-effective implementation of

concepts proposed above

• Requirements of advanced components and subsystems for future networks and subsystems

• Test-bed(s) predispositions for integrating and testing the advanced functionalities of the produced prototypes (starting from FP5)

Network services

Service DescriptionLayer 1 Provides a physical layer (i.e. layer 1) service

between customer sites belonging to the same VPN. Connections can be based on physical ports, optical wavelengths or TDM timeslots.

Layer 2 Provides at data link layer (i.e. layer 2) service between customer devices belonging to the VPN. Forwarding of user data packets is based on information in the packets' data link layer headers, e.g. DLCI, ATM VCI/VPI, or MAC addresses

Layer 3 Provides a network layer (i.e. layer 3) service between customer devices belonging to the VPN. Forwarding of user data packets based on information in the Layer 3 header, e.g. IPv4 or IPv6 destination address.

Technical Approach

• Three time-frameworks– Short Term about 2007– Medium Term about 2010– Long Term about 2015

• For each time-framework:– Network architectures (modes), services and

solutions (transport, management and control)– Techno-economic evaluations– Feasibility studies and testing of innovative

functionalities

17

Short term network scenario

• Network architectures– Metro Ethernet and all IP

– WDM point-to-point static links

• Service scenarios– L1 VPN

– Ethernet Services

– GFP / VCAT / LCAS services

18

Medium term network scenario

• Network architectures– Metro Ethernet and all IP + ASON circuits

(both NG SDH and OTN – overlay model)

• Service scenarios– L1 (dynamic switching of NG SDH and OTN)

– L2 (Ethernet)

– L3 (IP)

19

Long term network scenario

• Network architectures– ASON/GMPLS (Multi-layers peer model)

– Introduction of an innovative L2 switching into the medium term scenario

– Inter-working Grid and GMPLS platforms

• Service layer scenario– Transparent optical network services

– Innovative L2 switching services

– Grid services over ASON/GMPLS

Conclusions

• NOBEL is dealing with end-to-end networking issues for metro-core

• Three major network scenarios are under consideration: expected results concern techno-economic evaluations, feasibility studies an testing of solutions for the transport, management and control planes of core-metro networks

• NOBEL will contribute to Standards and Fora (ITU, OIF, IETF), in order to create a consensus view on advanced and innovative solutions thus creating favorable conditions for the penetration of broadband services

• The collaboration with other IST IP Projects (e.g. MUSE and MUPPET) is aimed at creating an European joint force for core and metro networks enabling B4All and Research Networking
