What is the correct full form of DLCI?

Correct option is E

DLCI (Data Link Connection Identifier) is a field in Frame Relay networks used to identify a specific logical connection between endpoints. It ensures efficient routing of packets across virtual circuits.
Important Key Points:
1. DLCI is specific to Frame Relay and is unique for each connection.
2. It works at the data link layer of the OSI model.
3. Provides an efficient mechanism for managing multiple virtual connections.
Knowledge Booster:
· Frame Relay is a WAN protocol for fast packet switching.
· DLCI values are locally significant and mapped by routers.
· It supports point-to-point and multipoint connections.
