a. Which information are used by TCP during demultiplexing at the receiver. b. Suppose Host A sends two TCP segments back-to-back to Host B over a TCP connection. The first segment has sequence number 70; the second has sequence number 130. How much data in terms of bytes is in the first segment? Suppose that the first segment is lost but the second segment arrives at B. In the acknowledgment that Host B sends to Host A, what will be the acknowledgment number? c. Suppose that TCP's current estimated values for the round trip time (estimatedRTT) and deviation in the RTT (DevRTT) are 250 msec and 14 msec, respectively. Suppose that the next two measured values of the RTT are 270 msec and 240 msec. Compute the values of the TCP TimeoutInterval after each of these two measured RTT values are obtained. Use the values of a = 0.125, and ß = 0.25.
