[Solved] TCP: Socket send/recv order [closed]

by

Introduction

TCP is a reliable, connection-oriented protocol used for communication between two hosts over a network. It is one of the most commonly used protocols in computer networks. The Transmission Control Protocol (TCP) is responsible for ensuring that data is sent and received in the correct order. This article will discuss the order in which data is sent and received using TCP sockets. It will also discuss the implications of this order on application performance and reliability.

Solution

The order of send/recv operations in TCP sockets is not guaranteed. The order of data sent by the sender may not be the same as the order of data received by the receiver. The TCP protocol ensures that all data is received correctly, but does not guarantee the order in which it is received.


I’m guessing you use TCP? Then you have to remember that TCP is a streaming protocol, without message boundaries and without any start or end (except connection established and closed).

A single recv call may receive less or more than what was sent in a single send call.

You need to come up with a higher-level protocol which incorporates message boundaries explicitly, for example by sending the length of the data to be received. Then you have to use loops to receive the correct amount of bytes.

Solved: TCP Socket Send/Recv Order

The order of sending and receiving data over a TCP socket is an important factor to consider when developing a network application. In this article, we will discuss the order of sending and receiving data over a TCP socket and how to ensure that the order is maintained.

What is the Order of Sending and Receiving Data Over a TCP Socket?

The order of sending and receiving data over a TCP socket is determined by the order in which the data is sent and received. The sender must send the data in the same order that it was received, and the receiver must receive the data in the same order that it was sent. This ensures that the data is received in the same order that it was sent, and that the data is not corrupted or lost.

How to Ensure the Order of Sending and Receiving Data Over a TCP Socket?

To ensure that the order of sending and receiving data over a TCP socket is maintained, the sender must use a reliable protocol such as TCP. This ensures that the data is sent in the same order that it was received, and that the data is not corrupted or lost. Additionally, the sender must use a sequence number to keep track of the order of the data being sent and received. This sequence number is used to ensure that the data is received in the same order that it was sent.

Conclusion

In conclusion, the order of sending and receiving data over a TCP socket is an important factor to consider when developing a network application. The sender must use a reliable protocol such as TCP and a sequence number to ensure that the data is sent and received in the same order. By following these steps, the order of sending and receiving data over a TCP socket can be maintained.
