计算机网络试验3TCP试验

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 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：TCP port number：11612. What is the IP address of On what port number is it sendingand receiving TCP segments for this connection答： the IP address of ：IP address： 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 答： My client computer:IP address:What is the sequence number of the TCP SYN segment that is used to initiate theTCP connection between the client computer and 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 the client computer in reply to the SYN What is the value of the ACKnowledgement field in the SYNACK segment How did 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 is:0；SYNACK segment 中 ACKnowledgement 的值为 1；ACKnowledgement number 的值为 SYN消息中 sequence number 加上 1 所得；SYN 和 Acknowledgement f 都置为 1 说明这是一个SYNACK segment.6. What is the sequence number of the TCP segmen...
