We present a session initiation protocol (SIP) network design for a voice-over-IP (VoIP) network to prevent congestion caused by people calling friends and family after a disaster. The design increases the capacity of SIP servers in a network by using all the SIP servers equally. The design uses a property that SIP network elements do not carry voice data packets but signaling packets instead. Furthermore,...
In UDP over Optical Burst Switching (OBS) network, congestion control is more important than other factors because burst losses cause serious performance decrease. Due to no congestion control in UDP, we propose a method to avoid congestion situation in UDP over OBS using session initiation protocol (SIP) in application layer. From numerical analysis, we can predict limiting the number of session...
