Suppose host A is connected to a router R1, R1 to another router R2 and R2 turn to host B. Assume a transport layer packet of 1448 Byte data and 20 byte (transport layer) headers are stored in the network layer of the Hosts A processed for sending to Host B. The IP layer does not set any options in the IP header. Assume that the link A-R1 has a maximum frame size of 1024 bytes including a 14-byte frame header, Link R1 - R2 can have a maximum frame size of 576 bytes with an 8 byte frame header and the link R2 - B supports a maximum frame length of 576 bytes including 14 byte frame header. a) Set the IP header fields Total Length, Identification, DF, MF and Fragment Offset in each packet sent via the three links. Here is a Reassembly in fragmentation only on the IP layer of the destination host B done b) What changes if a reassembly is enforced directly at the next node? becomes?
