What are the interconnected devices that can implement different network layer protocol conversion functions?

The interconnection device that can realize different network layer protocol conversion functions is a router. Routers perform protocol conversion of the OSI network layer and its lower layers, and can be used to connect two or more networks that differ only in the lower three layers. The function of a router is to transmit data between different subnets.

Routers perform protocol conversion of the OSI network layer and its lower layers, and can be used to connect two or more networks that differ only in the lower 3 layers.

The bridge provides protocol conversion between link layers and stores and forwards frames between LANs.

The function of a router is to transmit data between different subnets. The specific functions are as follows:

(1) Realize the interconnection of IP, TCP, UDP, ICMP and other networks.

(2) Process the data. It can send and receive data packets and has various functions such as packet filtering, multiplexing, encryption, compression and protection wall of data.

(3) Select the next transmission destination of the data packet based on the information in the routing table.

(4) Exchange topology information between the external gateway protocol and other autonomous domains.

(5) Implement network management and system support functions.
