Discussion
A station in a network forwards incoming packets by placing them on its shortest output queue. What routing algorithm is being used ?
Answer: A
The algorithm is hot potato routing.
In hot potato routing a station gets rid of each incoming packet as fast as possible by putting it on the shortest output queue, regardless of where that line leads, as if the packet were too hot to hold.
Flooding sends every packet out on every line except the one it arrived on. Static routing uses fixed tables computed in advance. Delta routing combines central routing information with local measurements such as queue lengths, so it is not the simple shortest-queue rule.
