Abstract
18A method and system for controlling the switching and control operation of at least one of an Softswitch system, an Signal Transfer Points (STP) and a gateway (GW) (e.g., in a SS7 signaling environment). By providing support for redundancy, a second switch system can take over the routing and control operations of a first switch system when the first switch system experiences difficulty. Difficulty may be any one of several forms (e.g., switch crash, congestion, hardware failure).
