For more information about the OSI Reference Model, see Building Modern Networks, by Steven Noble, Packt Publishing.

Additionally, you can refer to Computer Networking: Beginner's Guide for Mastering Computer Networking and the OSI Model by Ramon Nastase's, and The OSI Model for Network Engineers: Improve Your Network Troubleshooting, by Al Rivas. Both are available in e-book form on amazon.com, and will provide a much more thorough examination of the OSI stack than I had time or space to cover in the context of this chapter.
