Consider the scenario wherein a mobile host (MH) is communicating with a fixed host (FH) through Mobility Support Router (MSR-1) using the Indirect TCP (I-TCP) protocol. The MSR sends to the MH the packets P1, P2, P3, P4 and P5 in that order. Packet P3 is dropped but packet P4 reaches the MH causing it to generate the first duplicate acknowledgement (DUPACK). Before this DUPACK packet arrives at the MSR it has already sent out packet P5. Write down the sequence of steps that will be performed by the MSR and MH to bring the system to a consistent state. (5 marks) The MH now moves from MSR-1 to another cell (MSR-2). Detail the sequence of step required to move the connection to the new MSR.
