Survivable Signalling Network simulator

The Survivable Signaling Network (SSN) simulator has been developed to simulate the whole SSN network and to study its algorithms and performance requirements. The simulator implements SSN algorithms and uses accurate delay information to provide a rich set of simulation and output capabilities. It also includes a user-friendly graphical interface for SUN workstations, and is portable and very efficient in memory usage and computation speed. The simulation studies show that the most important delay component of the response time is the throttle interval used in transmitting link state packets. The number of links and the link distribution have significant impact on the performance and survivability of SSN. Under a reasonable design range, the damage response time for massive failures is less than one minute
