计算机网络实验报告三TCP 实验1. What is the IP address and TCP port number used by the client computer (source)that is transferring the file to gaia.cs.umass.edu? To answer this question, it’sprobably easiest to select an HTTP message and explore the details of the TCPpacket used to carry this HTTP message, using the “details of the selected packetheader window” (refer to Figure 2 in the “Getting Started with Wireshark” Lab ifyou’re uncertain about the Wireshark windows).答：client computer (source)：IP address：192.168.1.102 TCP port number：11612. What is the IP address of gaia.cs.umass.edu? On what port number is it sendingand receiving TCP segments for this connection?答：the IP address of gaia.cs.umass.edu：IP address：128.119.245.12 port number：803. If you have been able to create your own trace, answer the following question:What is the IP address and TCP port number used by your client computer(source) to transfer the file to gaia.cs.umass.edu?答：My client computer:IP address:10.2.136.304. What is the sequence number of the TCP SYN segment that is used to initiate theTCP connection between the client computer and gaia.cs.umass.edu? What is it in the segment that identifies the segment as a SYN segment?答：sequence number:0 ；syn 被设置为 1 说明是 syn 段。5. What is the sequence number of the SYNACK segment sent by gaia.cs.umass.eduto the client computer in reply to the SYN? What is the value of the ACKnowledgement field in the SYNACK segment? How did gaia.cs.umass.edu determine that value? What is it in the segment that identifies the segment as a SYNACK segment?答：The sequence number of the SYNACK segment sent by gaia.cs.umass.edu is:0； SYNACK segment 中 ACKnowledgement 的值为 1；ACKnowledgement n...
