SOLUTION TO WIRESHARK HTTP CODE

Explain these values.Ĭompute the throughput for data sent from source to destination. Each of these needs to be done empirically:Ĭount the number of TCP flows initiated from the senderįor the first 2 transactions after the TCP connection is set up (from sender to receiver), get the values of the Sequence number, Ack number, and Receive Window size.

SOLUTION TO WIRESHARK HTTP CODE

Use your `` analysis_ pcap_tcp” code to analyze assignment2.pcap and answer the following questions (Ignore any traffic that is not TCP). Node 130.245.145.12 establishes the connection (lets call it sender) with 128.208.2.198 (lets call is receiver) and then sends data.

You need to then write code to analyze the bytes to get the information about the packet.Īttached to the homework is a file assignment2.pcap. The PCAP library can be used to figure out where the first packet ends and the second packet starts. You may only use the PCAP library to get each packet in byte format. You may use a PCAP library to analyze the trace. A TCP flow starts with a TCP “SYN” and ends at a TCP “FIN”. Your task is to write a program `` analysis_pcap_tcp” that analyzes a Wireshark/TCPdump trace to characterize the TCP flows in the trace. Part A Wireshark Programming Task (45 points) PCAP library is a library available to parse the files.

PCAP is the file format used to store the captured packets.

When you exchange packets between A and B, Wireshark/TCPDump will let you capture the packets that are being sent out and received at A (or at B, depending on where you run the tool). Briefly, TCPdump/Wireshark are both tools to capture packets going on the wire. We will go over TCPDump, Wireshark, and PCAP file formats in class. To do this, you should be familiar with the packet formats, PCAP files, TCPDump, and Wireshark. The goal of this assignment is to dissect the HTTP and TCP protocols using the Wireshark tool. The last few weeks we have been talking about HTTP, TCP, and Congestion Control.
