Session Layer Explained | Layer-5 | Session Layer diagram
Session Layer:
Ø
Session layer in OSI reference model is responsible for establishing, maintaining and terminating the sessions.
Ø Session Layer is also called as Layer 5.
Ø Session Layer is also called as Layer 5.
Ø
It deals with sessions or interactions between the
applications(Live example of Phone call)
Ø
Session ID is used to identify a session or interaction.
Ø
Ex: RPC,SQL,NFS
Specific Responsibilities of Session Layer in Computer Network:
Ø
Dialog control: The session layer allows two systems to enter into a dialog. It allows the communication
between two processes to take place in either half-duplex
(one way at a time) or full-duplex
(two ways at a time) mode.
Ø
Synchronization: The session layer allows a process to add checkpoints, or synchronization
points, to a stream of data. For example, if a system is sending a file
of 2000 pages, it is advisable to insert checkpoints after every 100 pages to
ensure that each 100-page unit is received and acknowledged independently.

ReplyDeleteGreat post! The session layer in the OSI model plays a crucial role in establishing, managing, and terminating communication sessions between devices. It ensures smooth data exchange and synchronization during interactions. Understanding the session layer helps in grasping how networks maintain reliable and organized communication. Thanks for the informative content!
