The impact of TLS on SIP server performance

Charles Shen, Erich Nahum, Henning Schulzrinne, Charles Wright
2010 Principles, Systems and Applications of IP Telecommunications on - IPTComm '10  
This paper studies the performance impact of using TLS as a transport protocol for SIP servers.  ...  A key component of this is securing the signaling path, which is performed by SIP. Securing SIP is accomplished by using TLS instead of UDP as the transport protocol.  ...  We have evaluated and analyzed the impact of using TLS as a transport on SIP server performance versus the standard approach of SIP-over-UDP.  ...

Bandwidth Allocation and Session Scheduling using SIP

Hassan Hassan, Jean-Marie Garcia, Olivier Brun
2006 Journal of Communications  
Session Initiation Protocol (SIP) is a new signaling protocol designed to establish multimedia sessions in telecommunication networks.  ...  Hence, we use SIP to achieve QoS management on a session basis, in which the over all activity of the user during the session is considered.  ...  SDP is completely independent of transport protocol. It concerns mainly the format of session description and is designed to work with any transport protocol.  ...
