What are the desing issues of session layer?

The design issues of the session layer primarily include session establishment, maintenance, and termination, which involve ensuring reliable communication between applications. Additionally, it must manage synchronization, allowing for data exchange at specific checkpoints to recover from interruptions. Security aspects, such as authentication and encryption, are also crucial to protect the data being transmitted during a session. Finally, the layer must handle session restoration and recovery in case of failures, ensuring consistent communication.
