Testbed of OBS/GMPLS interworking

A testbed of OBS/GMPLS interworking network is established with the supporting of the BUPT-KDDI cooperation project. A dedicated GMPLS border controller with necessary GMPLS extensions and some OBS extensions are introduced in this network to achieve a dynamic, efficient and transparent inter-domain burst header packet (BHP) and data burst (DB) transmissions over the GMPLS-controlled optical circuit switching OCS network. The dynamic restoration in the OBS domain and the GMPLS protection/restoration in the OCS network are implemented in this testbed to demonstrate streaming media transmission in the multilayer network with different QoS requirements.
