6
b) Your company has the network ID 165.121.0.0. You are responsible for creating subnets on the network, and each subnet must provide at least 900 host IDs. What subnet mask meets the requirement for the minimum number of host IDs and provides the greatest number of subnets ?
6
c) Discuss three way handshaking of TCP, and three protocol scenarios which happens during connection establishment.
8
7. a) Given the network below and using the metrics shown on the links as the basis for optimality, sketch the shortest path from A to J using Dijkstra’s algorithm.
6
b) What is ARP ? Explain the purpose and use of ARP protocol.
6
c) With necessary block diagrams explain the working of HTTP protocol.
8
8. a) You are hired to design a reliable byte-stream protocol that uses a sliding window (like TCP). This protocol will run over a 1-Gbps network. The RTT of the network is 140 ms, and the maximum segment lifetime is 60 seconds. How many bits would you include in the AdvertisedWindow and SequenceNum fields of the protocol header ?
