A Mixed Message Distribution Inter-domain Signaling Protocol

REVP-TE is the signaling protocol of GMPLS, which is widely applied in ASON. When it is used to set up a connection, the distribution of messages usually adopts the serial or the parallel mode as well as several new proposed methods. Considering the drawbacks in both of the methods, and the lack of a fast message sending method suitable for inter-domain optical network, we propose a novel inter-domain signaling protocol MDSP based on the topology aggregation of inter-domain and new added new message types for RSVP-TE. MDSP introduces a mixed message distribution method serial distribution in intra-domain and parallel distribution in inter-domain. Through mathematical analysis and network simulation, it's proved to be an efficient signaling protocol, achieving a less connection setup time and blocking probability in multi-domain.
