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.
