Abstract:
A method for discovering topology in an SIP network is disclosed. According to the method, the SIP network is divided into domains governed by corresponding SIP proxies. A management system creates a topology agent for each SIP-domain and registers it with the governor proxy of each SIP-domain. Each topology agent generates topology-exploring messages to other agent and accumulates topology-exploring messages from other agents, gather routing information of the SIP network based on the collected topology-exploring messages to deduce topology of the SIP network.
