Advantages of the I-TCP

Question

Write down the advantages of the I-TCP.

Answer 1

a) I-TCP does not need any changes within the TCP protocol as used by hosts within the fixed network or other hosts in the wireless network which do not use this optimization.

b) Without dividing, retransmission of the lost packets would take place between the mobile host and the correspondent host across the whole network.

c) Optimization of new mechanisms is simple to be done in I-TCP since they only cover the single hop.

d) The short delay between mobile host and foreign agent may be calculated and is not dependent on the other traffic streams. Thus, an optimized TCP may use the precise time-outs to guarantee the retransmission as rapidly as possible.
