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 ...
Session-layer services are commonly used in application environments that make use of remote procedure calls (RPCs). [2] 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.
Session started as a fork of another messenger, Signal, aiming to build upon its foundation. However, concerns about the centralized structure of Signal Protocol and potential metadata collection led the team to deviate and create their own protocol, called "Session Protocol". This approach prioritized increased anonymity and decentralization.
to do an attachment file transfer; to do some photo sharing (e.g., Image Share) based on prior exchange of capabilities between the user endpoints; MSRP session is set up through SIP's offer-answer [3] model. The SDP m-line media type is message and the protocol is either TCP/MSRP for MSRP over TCP and TCP/TLS/MSRP for MSRP over
SIP is a text-based protocol with syntax similar to that of HTTP. There are two different types of SIP messages: requests and responses. The first line of a request has a method, defining the nature of the request, and a Request-URI, indicating where the request should be sent. [19] The first line of a response has a response code.
Multiple protocols often describe different aspects of a single communication. A group of protocols designed to work together is known as a protocol suite; when implemented in software they are a protocol stack. Internet communication protocols are published by the Internet Engineering Task Force (IETF).

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 ...
