Abstract :
Fault-tolerance of session control systems based on the session initiation protocol (SIP) is achieved by multiplying session-stateful servers and by replicating their session states. Replication can cause service inconsistency. An update commit algorithm (UCA) for adaptive consistency control is proposed. Analytic and simulation results show that the UCA provides the user- and operator-tolerable consistency/performance trade-offs.
