Question

TCP sender and receiver communicate over a connection in which the sender->receiver segments may be lost. The TCP sender sends an initial window of 4 segments. Suppose the initial value of the sender->receiver sequence number is 86 and the first 4 segments each contain 145 bytes. The delay between the sender and receiver is 7 time units, and so the first segment arrives at the receiver at t=5. As shown in the figure below, 0 of the 4 segment(s) are lost between the segment and receiver.

  1. Give the sequence numbers associated with each of the 4 segments sent by the sender. Format your answer as: x,y,z,...
  2. Give the ACK numbers the receiver sends in response to each of the segments. If a segment never arrives use 'x' to denote it, and format your answer as: x,y,z,...
