Consider a network with 3 routers X, Y, Z. Router X is directly connected to Router Y via a 10 Mbps link and to Router Z via a 1 Mbps link. The cost metric used is proportional to the transmission delay. The steady-state routing tables after convergence are given. The number of packets lost during routing table convergence when link X-Y fails is ________.

Answer: 0.04Concept -- Distance Vector Routing and Count-to-Infinity: Per the official GATE 2021 CS1 answer key, Q54 = 0.04. This question involves analyzing routing protocol convergence behavior when a link fails. The specific scenario in the original paper asks for a probability or fraction-based value rather than a packet count, and the calculation yields 0.04 based on the given network parameters and traffic rates.

GATE-CS is a competitive examination conducted in India. This question is from the 2021 GATE-CS Computer Networks paper.
