1. WP-JP-B Optical Burst Switching Progress report YEAR 1e1+ Review Meeting Javier Aracil – javier.aracil@uam.es Universidad Autónoma de Madrid

2. Content • Introduction • Involved partners • Main activities (ongoing and planned) • Achievements (with specific listing of quantitative achievements, e.g. joint papers or jointly organized events) • Status of milestones and deliverables (planned and actual delivery dates) • WP budget allocation • Main meetings (occurred and planned)

3. Optical Burst Switching • Control and data information travel separately on different channels • Data coming from legacy networks are aggregated into a burst unit in edge node • The control packet is sent first in order to reserve the resources in intermediate nodes • The burst follows the control packet with some offset time, and it crosses the nodes remaining in the optical domain OBS node Reserv. manager OBS network Switching times:ms ÷ s Assembly manager Burst size: kB ÷ MB Control channels offset Data channels ... Legacy networks WDM links Out-of-band signal.

4. Objectives • To analyze network architectures and routing strategies for OBS • To investigate contention resolution schemes, together with reservation and scheduling techniques. • In parallel, to examine traffic modeling issues, including influence of burstification algorithms and self-similarity. • To study OBS service provisioning aspects and TCP over OBS issues • To investigate design alternatives for OBS edge and core routers, including physical devices for OBS networks. • To study dependability, protection and restoration issues.
