Solution
The services that may be implemented in a link-layer protocol include:
-
Flow control between directly connected nodes: This is a mechanism to prevent a fast sender from overwhelming a slow receiver.
-
Coordinated access to a shared physical medium: This is necessary in a shared medium to avoid collisions and ensure fair access.
-
Reliable data transfer between directly connected nodes: This ensures that data is delivered from one node to another without errors.
-
Multiplexing down from / multiplexing up to a network-layer protocol: This allows multiple network-layer protocols to use the same link-layer protocol.
-
Bit-level error detection and correction: This is used to ensure data integrity by detecting and correcting errors that occur during transmission.
The services that are not typically provided by a link-layer protocol include:
-
Lookup and forwarding on the basis of an IP destination address: This is typically a function of the network layer.
-
TLS security (including authentication) between directly connected nodes: This is typically provided by the transport layer or application layer.
-
End-end path determination through multiple IP routers: This is typically a function of the network layer.
