  • IP is the internet layer which is layer 2 and TCP is the transport layer which is layer 3.

    Why split physical and data link when they are so closely related? You can’t use vpi/vci on an ethernet port, you can’t use MAC addresses on a frame relay port. Bundle that shit together.

    Presentation, application, and session are all dealt with by the application anyway so why bother splitting them out from a network point of view?
