In computer science and networking in particular, a session is a time-delimited two-way link, a practical (relatively high) layer in the TCP/IP protocol enabling interactive expression and information exchange between two or more communication devices or ends – be they computers, automated systems, or live active users (see login session). A ...
The Session Description Protocol describes a session as a group of fields in a text-based format, one field per line. [note 1] The form of each field is as follows. <character>=<value><CR><LF> Where <character> is a single case-sensitive character and <value> is structured text in a format that depends on the character. Values are typically UTF ...
An application instantiates the session with the Session Description Protocol (SDP) over Session Initiation Protocol (SIP) or other rendezvous methods. The MSRP protocol is defined in RFC 4975. [1] MSRP messages can also be transmitted by using intermediaries peers, by using the relay extensions defined in RFC 4976. [2]
The Session Initiation Protocol (SIP) is a signaling protocol used for initiating, maintaining, and terminating communication sessions that include voice, video and messaging applications. [1] SIP is used in Internet telephony , in private IP telephone systems, as well as mobile phone calling over LTE ( VoLTE ).
An example of a session-layer protocol is the OSI protocol suite session-layer protocol, also known as X.225 or ISO 8327. In case of a connection loss this protocol may try to recover the connection. If a connection is not used for a long period, the session-layer protocol may close it and re-open it.
HTTP (Hypertext Transfer Protocol) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. [1] HTTP is the foundation of data communication for the World Wide Web , where hypertext documents include hyperlinks to other resources that the user can easily access, for ...

Ossification is a major issue in Internet protocol design and deployment, as it can prevent new protocols or extensions from being deployed on the Internet, or place strictures on the design of new protocols; new protocols may have to be encapsulated in an already-deployed protocol or mimic the wire image of another protocol.
