Propose an extension to TCP by which one end of a connection can hand off its end to a third host; that is, if A were connected to B, and A handed off its connection to C, then afterwards, C would be connected to B and A would not. Specify the new states and transitions needed in the TCP state-transition diagram and any new packet types involved. You may assume all parties will understand this new option. What state should A go into immediately after the handoff?
