Medium Access Control
- Interfaces to the actual transport media to enable applications to communicate
- IEEE 802.5; ISO IS 8802-5
Logical Link Control
- Insures that all software implemented on the top five layers of the OSI Model remains independent of which physical network is implemented in the bottom of the model.
NETBIOS
- Constructs, maintains, and uses a table of relations between the Token Ring addresses and the defined names of units and services in the network; this enables real names to be used.

- Supports program to program communications between different systems through the Token Ring.
- Specific implementation of the IBM Systems Network Architecture (SNA) Logical Unit (LU) 6.2 architecture.
