OSI Layer 5: Session

10 Nov, 2008 - 1 minutes
As its name implies, the session layer establishes, manages and terminates sessions between two communicating hosts. The session layer provides its services to the presentation layer. It also synchronizes dialogue between the two hosts’ presentation layers and manages their data exchange. In addition to handling session regulation, the session layer offers provisions for efficient data transfer, class of service, and exception reporting of session layer, presentation layer and application layer problems.
