Nature inspired self-healing model for SIP-based services

The performance characteristics of Session Initiation Protocol (SIP) servers determine user-perceived quality of the services supported by SIP networks. SIP servers therefore must be able to provide service with appropriate reliability. We present the self-healing SIP model capable of recognizing and restarting failed SIP services without losing active SIP dialogs. Novel approach to an evaluation of the SIP server healthiness has been presented that enables rapid problem detection and consequently quick recovery. Tests show that a proposed model exhibits very promising results with respect to number of successful SIP requests during SIP server operation.
