 | | In the Open Systems Interconnection (OSI) communications model, the Session layer (sometimes called the "port layer") manages the setting up and taking down of the association between two communicating end points that is called a connection. |
 | | However, other sessions may last longer, usually with one or both of the communicating parties able to terminate it. |
 | | For Internet applications, each session is related to a particular port, a number that is associated with a particular upper layer application. |
