Name_______________________GT#___gt _ _ _ ECE3076 Homework 3 Due: Friday Feb. 16, 2007 (in class) 1 . TCP with no Congestion A 20 Mbps network connection has a 50 ms round trip time (RTT). A server begins sending maximum-size packets (after the initial SYN-ACK). The client ACK's every packet, and has a receiver-window which holds 15 maximum-size (1200 byte) packets. Show how many TCP segments (packets) are sent in each RTT period below: Time Period Start (ms) No. Segments sent 0 (SYN-ACK) 50 1 100 2 150 4 200 8 250 15 300 15 If the MSS is 1200 bytes, what is the average transmission rate during the first 200 ms (include bytes sent at periods 50-200 ms)? ___(1+2+4+8) x 1200 x 8/0.200 = 720,000 (bps) What is the maximum transfer rate (bytes/second)?_15 x 1200 x 8 / 0.050 = 2,880,000 (bps) 2 . Bandwidth-Delay Product a. What does TCP guarantee that UDP does not (for byte-stream sent in multiple packets)? Complete, in order delivery
