1. NOBEL Technical AuditWP3 Objectives & AchievementsFebruary xx, 2005 Workpackage 3 Advanced Burst/Packet Switching Gert Eilenberger

2. WP3 Objectives • Develop optical burst/packet switching techniques for high throughput core networks (e.g. terabit routers) and flexible, effective metro networks adopting data centric protocols (e.g. GEth) • Allow for evolution from wavelength (circuit) switched to burst/packet switched optical networks: exploit improved statistical multiplexing for lower overall port numbers to achieve lower cost. • Define network and node architectures to cope with data traffic profiles evolution (connectionless, bursty traffic, link to traffic characterization activities in WP1) and traffic volume increase (>10 Tbit/s per node) • Exploit transparent opt. wavelength/burst/packet switching to reduce O/E/O conversions and other el. hardware for reduced overall cost (link to WP5 for feasibility of burst/packet compatible transmission)

3. WP3 Objectives • Optimal balance between optical and electronic technologies in terms of performance and cost (links to WP7, 8) • Requirements and specifications for CP extensions specific to burst/packet techniques (link to WP4) • Novel network management functions adapted for optical burst/packet networks to provide configuration and fault management functions (in particular performance monitoring, protection and restoration). • QoS support in opt. burst/packet layer (reservation, allocation, signalling, signal regeneration etc.) • Elaborate possible extensions and/or evolution of standards

8. WP3 Interaction with other WPs • WP1: Provide inputs on burst/packet network scenarios and layering aspects to the NOBEL network vision. • WP2: Exchange info on Routing Management for burst/packet networks. • WP4: CP requirements/concepts to provide QoS in the new L2 burst/packet transport service. • WP6: Harmonization of burst/packet network and node architectures to be implemented by WP6. • WP7: Exchange of technology requirements and specifications for burst/packet nodes

9. WP3 Outlook for 2005 • Extension of preliminary results • Achieve a clear view on future advanced burst/packet network architectures • Roadmaps and evolution scenarios for their introduction • specify functional solutions in data, control and management plane (in particular for end-to-end QoS in burst/packet networks), • assess the underlying technologies for their potential implementation. • Contribute and impact future directions in standardisation activities on burst/packet networks from the viewpoint of a European network vision.
