Packet forwarding in computer networks
WebA router is a piece of network hardware responsible for forwarding packets to their destinations. Routers connect to two or more IP networks or subnetworks and pass data packets between them as needed. Routers are used in homes and offices for setting up local network connections. The simplest forwarding model—unicasting—involves a packet being relayed from link to link along a chain leading from the packet's source to its destination. However, other forwarding strategies are commonly used. Broadcasting requires a packet to be duplicated and copies sent on multiple links with the goal of delivering a copy to every device on the network. In practice, broadcast packets are not forwarded everywhere on a network, but only to devices within a broad…

The packet will take a shorter … WebLike hubs and bridges, switches may be interconnected to form larger networks. A switch's forwarding decision is based solely on layer 2 information. Switches do not modify the received packet. (Routers, by contrast, base their forwarding decision on layer 3 or network layer information, and also modify the received packets.)
