In this chapter, you learned about the functions of the session layer and the different processes that occur as data packets travel through this layer. More specifically, you learned that:

- The session layer establishes, manages, and terminates sessions between applications
- Communication sessions consist of mini-conversations that occur between applications located in different network devices
- Requests and responses are coordinated by protocols implemented at the session layer
- The session layer decides whether to use two-way simultaneous communication or two-way alternate communication by using dialogue control
- The session layer uses dialogue separation to orderly initiate, terminate, and manage communication

Now that you have completed this chapter, you should have a firm understanding of how the session layer provides transport services from the host to the destination. In the next chapter, you will examine what happens to data packets as they travel through the presentation layer of the OSI Model.
