Experimental implementation of a protocol interface between GMPLS and LOBS testbed

The multi-layer network for the interworking between Generalized Multi-Protocol Label Switching (GMPLS) and Labeled Optical Burst Switching (LOBS) is nowadays attractive for the future IP/DWDM network. In this paper, an effective protocol interface based on overlay model was proposed to enable the transparent transmission of Burst Header Packets (BHPs) and data bursts between OBS domains via a GMPLS network, while maintaining a simple interworking operation between LOBS and GMPLS networks. Moreover, the interface was implemented and evaluated by using a GMPLS/LOBS testbed, and the experimental results verified that it works effectively on the GMPLS/LOBS interconnection networks.
