What happens if a session is interrupted?

The session layer manages communication between two devices. It creates sessions and keeps them active. If something goes wrong—like a temporary disconnection or interruption—it tries to recover the session instead of starting everything from scratch.

How the Session Layer handles interruptions:

• It detects when a session has been broken or paused.


• It can restore the session from where it left off, depending on the protocol used.


• This ensures that the communication continues smoothly after the issue is resolved.

Importance in networking:

• This is useful in applications like file transfers, video conferencing, or remote desktops, where you don’t want to restart the entire session if something breaks temporarily.


• It also helps in providing a better user experience by minimizing data loss and time delays.


• Protocols at this layer manage checkpoints, so they can resume data transfer without sending everything again.

Conclusion: When a session is interrupted, the session layer does not ignore or discard the data. Instead, it tries to re-establish or resume the session, ensuring reliable communication between devices. This makes the session layer crucial for maintaining stable and efficient network interactions.
