| Main Objective: Up to now, research work on optical burst switching (OBS) networks has been concentrated on packets of version 4 of Internet Protocol (IPv4), called IPv4 datagrams. However, due the exhaustion of the IPv4 addressing space, it is expected that a transition from IPv4 to IPv6 (Internet Protocol version 6) will occur before the maturity of a scalable optical packet switching technology. This project addresses several issues of OBS networks in a transition scenario from IPv4 to IPv6. This project is organized into four tasks addressing: 1) new burst assembly algorithms for edge routers to natively support IPv4/IPv6 datagrams and IPv6 jumbograms; 2) the specification of an enhanced version of the Just-in-Time (EJIT) signalling protocol for core routers; 3) IPv4/IPv6 - compliant QoS Support using prioritized burst segmentation and composite burst-assembly techniques 4) the development of a testbed of an IPv4/IPv6- compliant OBS network. |
