What kind of operation do exist at session layer of OSI Model

———————————————————————

The Session Layer (Layer 5) of the OSI model is responsible for managing sessions between applications on different devices. It provides services that allow multiple applications to establish, maintain, and terminate communication sessions. Some of the key operations that exist at the Session Layer include:

1. **Session Establishment**: The Session Layer is responsible for setting up, managing, and terminating communication sessions between applications. It coordinates the start and end of sessions, ensuring that data exchange occurs in an organized manner.

2. **Session Maintenance**: Once a session is established, the Session Layer manages the ongoing communication between applications. It handles tasks such as session re-establishment in case of interruptions and maintaining session synchronization.

3. **Session Termination**: When the communication between applications is complete, the Session Layer ensures the orderly termination of the session. It releases resources, closes connections, and performs any necessary cleanup tasks.

4. **Dialog Control**: The Session Layer manages the dialog between applications, controlling the flow of communication and ensuring that data exchange occurs in a structured manner. It handles turn-taking and flow control mechanisms during the session.

5. **Synchronization**: The Session Layer is responsible for synchronizing data exchange between applications. It ensures that data is transmitted and received in the correct order and at the appropriate pace to maintain consistency in the communication process.

Overall, the Session Layer plays a crucial role in facilitating communication sessions between applications by providing services that enable the establishment, maintenance, and termination of sessions in a network environment.
