Overview#

Session is a semi-permanent interactive information interchange, also known as a dialogue, a protocol conversation or a meeting, between two or more communicating devices.

typically, the Protocol Client initiates a Session with a Protocol Server but may also, perhaps, incorrectly, refer to a peer-to-peer Session.

Communication Transport may be implemented as part of protocols and services at the application layer, at the session layer or at the transport layer in the OSI-Model.

Application layer examples:

  • HTTP Session, which allow associating information with individual visitors
  • A telnet remote login session

Session layer example:

  • A Session Initiation Protocol (SIP) based Internet phone call

Transport layer example:

  • A TCP Session, which is synonymous to a TCP virtual circuit, a TCP connection, or an established TCP socket.
