Session Initiation Protocol
Session Initiation Protocol
Unit 5
Abstract
Session Initiation Protocol also known as SIP it is a communication protocol that is extensively utilized for managing and terminating sessions in an IP based network. A session may be an easy end to end telephone call or shared multi-media meeting session. This can be setup to start services such as voice enhanced ecommerce; a simple click to call or IM’ing with a friend in an IP based organization. The session initiation protocol has been the preferred selection for VoIP (voice over IP) and is the standard set by the IETF (internet engineering task force) (Cisco, 2014). SIP is continuing to expand and being altered to consider all important characteristics as the technology develops and broadens. It is also good to know that SIP’s function is restricted to only the configuring and managing of sessions.
This first traditional switch based phone structure was the focus for transferring messages. Nevertheless, with the arrival of the internet, the necessity was believed to create a structure, that links individuals through an IP based structure. SIP is a request reply order, managing requests from clients and replies from servers. These requests can be transferred via any transport protocol like UDP (user datagram protocol) or even TCP (transmission control protocol) (Cisco, 2014). It decides the end system to be utilized for the session, the communications and media limits, and the contacted groups need to interconnect in the transmission. I will go further into the components, functions and recommendations of the session initiation protocol as I begin my explanation below.
Session Initiation Protocol The session initiation protocol has elements that incorporate user agents that can function in two ways. First, the user agent client can produce requests and transmit them to the servers. Secondly, the user agent server receives the request, handles them and produces the responses. So in
