Abstract :
The session initiation protocol (SIP) is the main signaling protocol in the 3GPP IP multimedia subsystem (IMS). The SIP sessions in IMS have to be highly reliable. A state-sharing algorithm based on file transfer protocols such as FTP and TFTP, is proposed to increase session reliability. Theoretical analysis and experimental scenarios showed that TFTP outperforms FTP.
