Routing device and a method of routing information in a communication network for signalling and information for management of communication networks

摘要

The invention relates to a device and a method for information transmission between a signaling communication network (SCN) and a management communication network (MCN) of an automatically switched optical network (ASON). The device comprises a control plane-related processing unit (11), a SCN interface adapter unit (21), a management plane-related processing unit (12), and a MCN interface adapter unit (22); and further comprises a route processing module connected with the two interface adapter units and having prioritizing and flow-limiting functions. The method comprises: the control plane-related processing unit or the SCN interface adapter unit generates a SCN information package with higher priority, while the management plane-related processing unit or the MCN interface adapter unit generates a MCN information package with lower priority, for the SCN and the MCN information packages with the same target DCN interface, the route processing module transfers the SCN information package preferably according to the priority. The device and the method can improve the performance of the control plane of ASON.
