Token-Ring Data Link Control Overview
The token-ring data link control (DLCTOKEN) is a device manager that follows the generic data link control (GDLC) interface definition. This DLC device manager provides an access procedure to transfer four types of data over a token ring:
- Datagrams
- Sequenced data
- Identification data
- Logical link controls
This DLC device manager also provides a pass-through capability that allows transparent data flow.
The token-ring device handler and the Token-Ring High Performance Network Adapter transfer the data, with address checking, token generation, or frame-check sequences.
