GATE CS 2010 Q55 — Routing Protocols: Shortest Path, Flooding, Distance Vector, Link State

An ISP having an address block $202.16.0.0/15$ assigns a block of $6000$ IP addresses to a client, using the classless internet domain routing (CIDR) super-netting approach. Which of the following address blocks can be assigned by the ISP?

Consider a file of size $4$ million bytes being transferred between two hosts connected via a path consisting of three consecutive links of bandwidth $2$ Mbps , $500$ kbps , and $1$ Mbps , respectively. All processing delays and propagation delays are negligible. Assume that there is no other background traffic over the path and no other additional …

Consider the routing protocols given in List I and the names given in List II: …

Consider a network path $\mathrm{P}-\mathrm{Q}-\mathrm{R}$ between nodes $\mathrm{P}$ and $\mathrm{R}$ via router $\mathrm{Q}$. Node $\mathrm{P}$ sends a file of size $10^6$ bytes to $\text{R}$ via this path by splitting the file into chunks of $10^3$ bytes each. Node $\text{P}$ sends these chunks one after the other without any wait time …

Consider the entries shown below in the forwarding table of an $\text{IP}$ router. Each entry consists of an $\text{IP}$ prefix and the corresponding next hop router for packets whose destination $\text{IP}$ address matches the prefix. The notation " /$\mathrm{N}$ " in a prefix indicates a subnet mask with the most significant $\mathrm{N}$ bits set …

Which of the following statements is/are $\text{INCORRECT}$ about the $\textsf{OSPF (Open Shortest Path First)}$ routing protocol used in the Internet?
