Networking , Technology & Science / April 26, 2018

Since the invention of the telephone, real time communication networks have mostly been built using closed circuit switched network infrastructures, e.g. the Public Switched Telephone Network (PSTN). With the advent and the increasing popularity of the packet-switched Internet data network, providers are seeking ways to combine both communication and data networks on an all-IP network basis. Session Initiation Protocol is a core protocol for coming real time communication networks. Session Initiation Protocol (SIP) is one of the most common protocols used in VoIP technology. It is an application layer protocol that works in conjunction with other application layer protocols to control multimedia communication sessions over the Internet. Overview of Session Initiation Protocol (SIP) Session Initiation Protocol (SIP) is an application-layer control protocol that can establish, modify, and terminate multimedia sessions (conferences). A session is considered as an exchange of data between an association of participants, such as Internet telephony calls and video telephony. SIP is able to support multicast conferences with more than two participants. Participants can be invited to already existing sessions. Media can be added to (and removed from) an existing session. SIP can be used to control Internet multimedia conferences, Internet telephone calls and multimedia distribution, in…
