1. Consider the below interconnection of networks that employ IPV4. Let the MTU of the Datalink layer of Ring topology is 4500 bytes, Bus topology is 1460 bytes, and the point- point network is 532 bytes. Let the sender A send a MP3 file of 2980 bytes to the Receiver G, using TCP type of transport layer and let the size of TCP header-20 bytes. Let the size of IP header=20 bytes. Let the IDENT value of the IP datagram is 3949. If at all fragmentation of a IP packet is done at any IP layer, the size of each of the fragment except the last one should be maximum MTU permitted in the DL of the corresponding IP layer. Fragment IDENT value Number B C Fragment bit value Table 1 a. For every fragment at the output of R12 interface of Router, enter the details as given in the above table1. Add more rows depending upon the number of fragments created. b. For every fragmented packet that reaches the Receiver G draw another version of the table as shown above and fill the details. All intermediate calculations need to be provided. [8 Marks] RI Offset value for fragment No of Data bytes for the fragment R21 R31 R32 1922 1호 염려 R2 1.
