If a packet is discarded by the Neighbouring router for any case an ICMP packet will be generated with the reason WHY the packet got discarded and that is HOW the router will come to know about the Neighbouring routers.

U = set-up time for circuit switch (seconds) Y = transmission delay per link (seconds) (also called “transfer delay”) L = message length (bits) >0 R = transmission rate (bits per second) >0 (also called “placement rate”) H = header size (bits) =>0 P = packet size (bits) >H (note that this is the total packet size, i.e. header + data) X = decision time per packet (also called “packet routing delay”) 1. If L=1000, Y=1, R=4000 and U=1, choose a value of X. What is the total transmission time in the circuit switch network and packet switched network? Consider P=125 and H=25. (3 marks)
