The Intermediate Node Class Of The Router

When the intermediate node router transmits in the network, it provides the storage and forwarding of packets. At the same time, according to the routing information maintained by the current routing table, the best path is selected to transmit packets. A router on the side of a corporate or enterprise network that is connected to the external WAN consisting of multiple interconnected LANs is the boundary router of the enterprise network. It collects information addressed to the enterprise network from the external WAN and forwards it to the relevant network segments in the enterprise network; On the other hand, the packets sent by each LAN segment in the enterprise network to the external WAN are centralized, and the best transmission path is determined for the related packets.
