1. If you have a class C network and require 10 subnets, how many bits do you need from the host part for creating the required subnets? What is the subnet mask of each subnet and how many valid addresses are available in each subnet ? (6 Marks) 2. Assume that MU has the following chunk of CIDR-based IP addresses available with it: 245.248.128.0/20. MU wants to allocate half of this chunk of addresses to the SoE, and a quarter each to SoL and SoM. Write all valid combinations of address allocations (in the form of a.b.c.d/x) to SoE, SOL and SOM respectively. (10 Marks) 3. Consider sending a 2400-byte datagram into a link that has an MTU of 700 bytes. Suppose the original datagram is stamped with the identification number 310. How many fragments are generated? What are the values in the various fields in the IP datagram(s) generated related to fragmentation? (8 marks) 4. Answer the following questions ((4+4) Marks) a) Station A uses 16 byte packets to transmit messages to Station B using a sliding window protocol. The propagation delay between A and B is 40 milliseconds and the bottleneck bandwidth on the path between A and B is 128 kbps. What is the optimal window size that A should use? oder window size for GBN protocol cannot be 2^k, if the sequence
