Explain the different Options used in IP Datagram.
Five equal-size datagrams belonging to the same message leave for the destinations one after another. However, they travel through different paths as shown in Table
We assume that the delay for each switch (including waiting and processing) is 3,
10, 20, 7, and 20 ms respectively. Assuming that the propagation speed is 2 x 108
m/s find the order the datagrams arrive at the destination and the delay for
each. Ignore any other delays in transmission.
