Host A wants to transfer 5000 bytes of data to Host B. On the network path there are two routers. First router R1, has MTU(Maximum Transformation Unit) of 1900 bytes. Second router R2, has MTU of 900 bytes. 1. How many packets will Router 1 will deliver to Router 2 ? 2. Draw packet formats with More Flag and Offset values and data sizes for each datagram for R1 . 3. How many packets will Router 2 will deliver to Host B ? 4. Draw packet formats with More Flag and Offset values and data sizes for each datagram for R2 sending to Host B.
