Control layer for multistage optical burst switching system and method

摘要

The invention provides a control layer for an Optical Burst Switch (OBS) system, said system comprising at least one stage configured with a closed optical burst switch addressing scheme and one or more ports for sending or receiving data packets. The control layer comprises a control addressing scheme independent of the closed optical addressing scheme and means to provide interconnectivity for each port with every other port. In one embodiment there is provided a closed optical burst switch ring network. The control layer encapsulates or maps the optical data at a port into an independent packet format and passes the independent packet format into a queuing system for transmission by the optical burst switch ring network to a destination port.

1. A method of controlling an Optical Burst Switch (OBS) system, said OBS system comprising at least one stage, each stage configured with a closed optical burst switch addressing scheme and one or more ports, each port adapted for sending or receiving optical client data, one or more of said ports adapted to support a plurality of client service formats, representative of different client data services;
implementing a control addressing scheme independent of the closed optical burst switch addressing scheme by encapsulating the optical client data at a port into a packet format, independent of the closed optical burst switch addressing scheme, to provide a control address, and passing the encapsulated packet format into a queuing system for onward transmission to a destination port; and providing interconnectivity for each port with every other port in said at least one stage.
