SSNM message mainly comprises: DUNA (Destination Unavailable, point of destination is unreachable) message, DAVA (Destination Available, point of destination can reach) message, DAUD (Destination StateAudit, the point of destination detection) message, SCON (Signalling Congestion, signaling congestion) message, DUPU (Destination User Part Unavailable, the point of destination client layer is unavailable) message etc.
The pass of setting between network element A, B, the C is B-A-C, then:
When between network element A and the network element B when reachable state becomes inaccessible state, network element A with the inaccessible state of network element B by DUNA message informing network element C.
When between network element A and the network element B when inaccessible state becomes reachable state, network element A with the reachable state of network element B by DAVA message informing network element C.
When network element B thinks that can't arrive network element C by network element A the time, network element B surveys the accessibility of network element C by regular transmission DAUD message.
When the signaling of network element A arrival network element C was in congestion state, network element A passed through SCON message informing network element B with this congestion state.
When the client layer of network element C was unavailable, network element C passed through DUPU message informing network element A with this down state.
