摘要
Embodiments of the present invention may enable applications that are deployed at the application layer of an IMS network to frequently carry out business critical functions via a highly available application server architecture. This may be achieved by using a session manager that manages the role of active and standby server(s) of the highly available application architecture. Further, the session manager may manage the roles of the active and standby server(s) by routing SIP messaging in either serial or parallel fashion to the application server architecture. Furthermore, the active and the standby servers are automatically kept in sync by their position in the signaling path determined by the session manager. The session manager makes sure that if the active server goes down, then the standby server must be able to take over the role of the active server in a seamless fashion.
