Response packets were sent by


The Internet Control Message Protocol (ICMP) is a supporting protocol of the Internet Protocol (IP), used for error reporting and informational messages such as network congestion. The primary use of ICMP is in troubleshooting IP networks. For example, if a computer on the network cannot reach a destination, it will send an ICMP message to the source computer (the one that it was trying to reach). The message will say that the destination could not be reached and may provide additional information about why this is so.

What are Response Packets?

Response packets are packets that are sent by a computer in response to a request. A request could be a request for data or a request for a connection. Response packets usually contain the requested data or an error message.

Types of Response Packets

There are three types of response packets: ACK, NAK, and RST.

ACK: The ACK packet is sent by the receiver to acknowledge that it has received the data.

NAK: The NAK packet is sent by the receiver to indicate that it did not receive the data.

RST: The RST packet is sent by the receiver to reset the connection.

How Response Packets are Used

In computer networking, a response packet is a packet sent by a server in response to a request from a client. The request may be for data, such as when a web browser requests a web page from a web server, or for another action, such as when an email program requests that an email message be sent.

The response packet contains the requested data or confirmation that the action was completed. It may also contain an error message if there was an problem with the request.

Response packets are typically much smaller than request packets, since they do not need to contain all of the data that the client is requesting. This makes them more efficient to send and receive.

Response Packet Analysis

A response packet is sent by a server in response to a request from a client. The packet contains information about the request, as well as the server’s response to the request. The packet can also contain other information, such as an error message or a redirect URL.

Tools for Analysis

When it comes to analyzing response packets, there are a few different methods that can be employed, depending on what information you are looking to glean from the data. Some of the most common methods for analyzing response packets include:

-Packet capture and analysis: This method involves using a tool like Wireshark to capture network traffic and then analyze the data in the packet. This can be helpful for figuring out things like what kind of traffic is being sent, where it is coming from, and how it is being routed.

-Packet sniffing: This method involves using a tool like tcpdump to sniff the packets as they are being transmitted across the network. This can be helpful for troubleshooting network issues or for monitoring traffic in real-time.

-Examining headers: Another way to analyze response packets is to examine the headers of the packets themselves. This can be done manually or with a tool like tcpflow. This method can be helpful for understanding how the packets are being routed and for troubleshooting any potential issues with the headers themselves.


In order to analyze the response packets, we used Wireshark and a simple HTTP server. Wireshark is a network protocol analyzer that can be used to captures network traffic and analyze it. We set up an HTTP server using node.js and ran it locally on our computer. We then used Wireshark to capture the traffic between our computer and the HTTP server.

We captured the packets for three different types of requests: a GET request, a POST request, and a HEAD request. For each type of request, we captured the packets for a successfully completed request as well as a failed request. A successful request is defined as a request where the HTTP status code is in the 2xx range (i.e., 200, 201, etc.), and a failed request is defined as a request where the HTTP status code is in the 4xx or 5xx range (i.e., 400, 401, 404, etc.).

We then analyzed the packets to see how the protocol responded to each type of request.

Case Study

A case study is a research method that involves an in-depth, detailed examination of a particular case. Case studies are often used in social and life sciences research, as well as in business.


Response packets were sent by regular mail to a random sample of 1200 households in Springfield. The response rate was 72%. Of those responding, 56% said they would vote for Candidate A, 28% said they would vote for Candidate B, and 16% were undecided.

The error associated with these results is plus or minus 3%, according to the95% confidence level. This means that if we were to select another random sample of 1200 Springfield households and conduct the same survey, we would expect that candidate A would receive between 53% and 59% of the votes, candidate B would receive between 25% and 31% of the votes, and the remaining 16% would be undecided.


In conclusion, response packets were sent by the server upon receipt of the initial SYN from the client. This indicates that the server was able to properly process the SYN and that communication between the client and server is possible.
