1. Explain exactly how routers route packets.
The routers employ the use of packet switching whereby, packets are directed towards a specified route and the transit is logically addressed from their source towards the ultimate destinations through intermediate nodes. The routing process usually directs the forwarding of packets on the basis of routing tables which has a record of the routes to various network destinations. Most of the routing algorithms make use of only one network path at a time whereas the multipath routing techniques enable the use of multiple alternative paths. A router typically organises and controls data flow among the computers on the network and other network ...
