Select a TCP segment in the Wireshark’s “listing of captured-packets” window. Then select the menu : Statistics->TCP Stream Graph-> Time-Sequence-Graph(Stevens).
Problems 13~14
Use the Time-Sequence-Graph(Stevens) plotting tool to view the sequence number versus time plot of segments being sent from the client to the gaia.cs.umass.edu server.
Can you identify where TCP’s slowstart phase begins and ends, and where congestion avoidance takes over? Comment on ways in which the measured data differs from the idealized behavior of TCP that we’ve studied in the text.
Answer the questions above for the trace that you have gathered when you transferred a file from your computer to gaia.cs.umass.edu

1. Can you identify where TCP’s slowstart phase begins and ends, and where congestion avoidance takes over?
2. Comment on ways in which the measured data differs from the idealized behavior of TCP that we’ve studied in the text.
본문내용
다음은 wireshark 로 캡쳐한 음원파일 전송과정을 Sequence Numbers(Stevens) 로 시각화한 그래프이다 . 그래프를 살펴보면 slow start 구간은 sequence number 가 곡선형태로 증가하는 0 초 1.8 초이다 . Sequence number 가 계속해서 증한다 . 즉 재전송된 패킷은 없다 .
