Fhotonic burst switching (PBS) architecture for hop and span-constrained optical networks

A new architecture called photonic burst switching (PBS) with variable time slot provisioning, supporting high-speed bursty data transmission within hop and span-constrained networks, is presented as follows. First, the edge and switching node architecture for in-band and out-of-band signaling with the optical switch fabric performance parameters is defined. Second, the edge router regions of operation for burst assembly are studied via simulations. Third, we introduce: . A GMPLS-based PBS software architecture in terms of control and data plane operations that is extended to enable the PBS optical interfaces with the software building blocks for edge and switching nodes . An adaptive PBS MAC layer functionality and framing of multiple generic payloads The integration of the proposed PBS network architecture with low-cost optical switching fabrics and GMPLS-based software architecture should provide the means for robust and efficient optical transport of bandwidth-demanding applications within enterprise networks.
