A novel scheme of signaling protocol based on mobile agent and OBS

A novel scheme of signaling protocol based on mobile agent and OBS which runs over a core DWDM network is promoted. Design of optical wavelength channels in the scheme is to choose 1310nm band to be control optical wavelength channel to transmit BHPs and 1550nm band to be burst packets optical wavelength channels to transmit BPs. Referring to RSVP-TE in DCM ASON, significations and formats of signaling messages in the protocol are defined. The key design of scheme is to utilize the structure of active packets in the application of mobile agent MANet to encapsulate signaling messages and traffic together into one BHP to shorten the set-up time of an optical path. Such structure is also used to process distributed disposals to alleviate the workload of one node in the network to promote cooperating calculation ability of each node in the network. The communication between a source node and a destination node through one or multiple intermediate nodes is presented as an example to describe the processing procedures of the protocol. The scheme is implemented in a wavelength router, which is briefly introduced.
