Research And Implementation Of Routing Protocol In ASON Control Panel

This paper based on the deep study of OSPF (Open Shortest Path First) protocol and the ASON (Automatically Switching Optical Network) control plane techniques according to the standards presented by ITU-T, IETF, OIF, presents the implementation model of the OSPF based on GMPLS. This paper designs and implements the functions of OSPF protocol. According to the OSPF protocol, every control node in the area can maintain the synchronization of topology information. This makes it possible to provide real-time and precise topology information for the end-to-end routing configuration in ASON networks. This paper implements the functions of the OSPF protocol including adjacent relations maintenance, LSA flooding and the LSA database maintenance.
