What is a role of the Logical Link Control sublayer?
- to provide access to various Layer 1 network technologies
- to provide data link layer addressing
- to define the media access processes performed by network hardware
- to mark frames to identify the network layer protocol being carried
There are two data link sublayers, MAC and LLC. The LLC sublayer is responsible for communicating with the network layer and for tagging frames to identify what Layer 3 protocol is encapsulated.
