Definition of packet forwarding in The Network Encyclopedia.

What is packet forwarding?

The process of a networking component accepting a packet and transmitting it to its destination. For example, a router receives packets from hosts on one attached network and forwards them to hosts on another attached network or to another router for further forwarding.

How a packet is forwarded is based on a comparison of the packet’s destination address with the routing table stored in the router. Each act of forwarding performed by a router is called a hop across the internetwork.
