GATE CSE 2023 | Question: 15
Which of the following statements is/are $\text{INCORRECT}$ about the $\textsf{OSPF (Open Shortest Path First)}$ routing protocol used in the Internet? $\textsf{OSPF}$ implements Bellman-Ford algorithm to find shortest paths. $\textsf{OSPF}$ ... path routing. $\textsf{OSPF}$ is used as an inter-domain routing protocol. $\textsf{OSPF}$ implements hierarchical routing.

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)

GATE CSE 2022 | Question: 47
Consider a network with three routers $\text{P, Q, R}$ shown in the figure below. All the links have cost of unity. The routers exchange distance vector routing information and have converged on the routing tables, after which the link $\text{Q-R}$ ... off to one decimal place) between $\text{P}$ and $\text{Q},$ leading to count-to-infinity problem, is _______________.

Network Layer - Computer Networks - Tanenbaum
The question states - An IP datagram using Strict source routing option has to be fragmented. Do you think the option is copied into each fragment, or is it sufficient to just put it in the first fragment? Explain your answer. My thinking ... every fragment. I doubt this reasoning and don't see any flaws in my own answer. Where is my answer lacking?

GATE Overflow | Mock GATE | Test 1 | Question: 31
Let $N$ be the number of nodes and $M$ be the number of edges. For Link state routing how many message exchanges (roughly, explained as a function of the above parameters) need to be exchanged to build the topology at each and every node in the network? $\text{Min } (N+M, N*M)$ $\text{Max } (N+M, N*M)$ $N*M$ $N+M$

Distance vector routing protocol
At the beginning each node knows only the distances to its immediate neighbors. In step 1, each node exchanges its routing table with all of its neighbors and all update their routing tables accordingly. In step 2, step 1 repeats. After step 2, at node A, ... minimum cost path to D? What will be the new value of the B-C link. Assume cost values are always >=1.
