The OSI Session Layer

By Stephen Bucaro

The Session layer, layer seven of the OSI model, establishes, synchronizes, maintains and terminates sessions between computers on a network. It establishes a connection ID and authenticates security.

When you think of the Session layer, keep in mind that the OSI is only a model. Actual network protocol suites, such as TCP/IP handle the conection establishment, maintainance, and termination with protocols at the Transport layer.
