With the appearance of the Internet as an important communications medium for widespread everyday use, which can be dated to the mid 90s, a need to establish a signalization protocol for multimedia communications was recognized. There were two major proposals: SIP by the Internet community, and H.323 by ITU-T.

Evaluation of transport protocols for the session initiation protocol
IEEE Network, 2003SCTP is a newly developed transport protocol tailored for signaling transport. Whereas in theory SCTP is supposed to achieve a much better performance than TCP and UDP, at present there are no experimental results showing SCTP's real benefits. This article analyzes SCTP's strengths and weaknesses and provides simulation results.

An enhancement of ECC-based session initiation protocol
International Journal of Internet Technology and Secured Transactions, 2021Session initiation protocol (SIP) is the most prominent signalling scheme for controlling, establishing, maintaining and terminating communications on the internet. Many researchers are working to create strong protocols for secure communication using SIP. Tu et al.

Porting the session initiation protocol to IPv6
IEEE Internet Computing, 2003A modified Java-based SIP (session initiation protocol) implementation offers one approach to developing multimedia services that run on both IPv4 and IPv6 networks. This article describes our experiences in porting SIP to lPv6. To deploy a service in which IPv6 nodes communicate with IPv4 nodes, we selected an IPv4-IPv6 transition mechanism that ...

A Review of Formal Descriptions of Session Initiation Protocol [PDF]
Advanced Science and Technology Letters, 2014 The Session Initiation Protocol is used for establishing peer-to-peer sessions with one or more participants. Internet telephone calls, multimedia distribution, conference calls, and multiplayer online games are examples of these sessions. Since formal description is the first step of modeling and analysis of a system, this paper reviews formal ...

Bell Labs Technical Journal, 2004
The way we communicate at work, at home, and while traveling is beginning to change significantly once again. Users are hungry for new converged Internet Protocol (IP) multimedia services driven by new user devices and the wider availability of broadband access networks.

Performance Improvement of Session Initiation Protocol
2012 International Conference on Computer Science and Service System, 2012By analyzing the signal lings exchange of SIP deeply, GSPN model of protocol is established for evaluating the performance of protocol, reducing call setup time of SIP and obtaining a tradeoff between the performance and the number of buffer. Basing on the model, markov chain of model is designed.

Transport protocol considerations for session initiation protocol networks
Bell Labs Technical Journal, 2004The session initiation protocol (SIP), an application-layer protocol in the Internet protocol (IP) model, is increasingly being used for signaling Internet telephony multimedia sessions. The widespread applicability and use of SIP has engendered the use of diverse transport-layer protocols underneath it (e.g., user datagram protocol [UDP], transmission

SIP - the Session Initiation Protocol
2001Current Internet applications, such as e-mail and Web-browsing, are client/server based and do not require session set-up or control. They work very effectively on best-effort IP networks. In the future, it is envisaged that both fixed and mobile services will be provided by a QoS-enabled all-IP core network.

Cryptanalysis of an Authentication Protocol for Session Initiation Protocol
2011The session initiation protocol (SIP) is a challenge-response based authentication protocol which is used in 3G mobile networks. In 2010, Chen et al. proposed an authentication protocol for SIP using elliptic curves cryptography. However, this paper show that the Chen et al.
