Explanation of the source code construction protocol of the live broadcast platform: Transmission Control Protocol TCP

Introduction:

As the live broadcast platform is developing more and more rapidly in today's era, the technical functions of the live broadcast platform are becoming more and more intelligent, allowing users to interact with other users in real time on the live broadcast platform, allowing users to obtain the latest information from all over the world. Some users can get jobs as anchors, and other users can relax and be happy as viewers. Therefore, the source code construction of the live broadcast platform has become an area that many entrepreneurs want to get involved in. The source code construction of the live broadcast platform requires many key points, and the construction agreement is one of them. An important point, before that, I have explained the three protocols of the live broadcast platform, and today we will talk about the fourth protocol: Transmission Control Protocol TCP.

 

1. What is Transmission Control Protocol TCP?

The transmission control protocol is a protocol used in the source code network communication of the live broadcast platform. It is mainly used to transmit data. The TCP protocol defines the format of data transmission, error handling during transmission, flow control, and the sequence of data packets, etc., to ensure data integrity. Reliable transmission.

2. The role of transmission control protocol TCP in building the source code of the live broadcast platform

1. Stable data transmission: The transmission control protocol TCP can first play a role in stabilizing the data transmission of the source code of the live broadcast platform. The TCP protocol uses a three-way handshake to establish a stable connection with the live broadcast platform to ensure stable transmission of audio and video data and prevent data duplication or loss. Realize the stable transmission of data from the source code of the live broadcast platform.
2. Control traffic data congestion: When a certain number of users use the live broadcast platform at the same time, it may bring a large amount of traffic to the live broadcast platform. If the traffic cannot be transmitted separately, but transmitted at the same time, it may cause data congestion. The TCP protocol can control the amount of data sent through the sliding window mechanism to avoid network congestion caused by too much data being sent at the same time.
3. Monitoring data: After the source code of the live broadcast platform is built, the amount of data on the platform is very large. In the huge data, there will inevitably be data such as duplication and errors. The appearance of these data will affect the normal service of the live broadcast platform and user experience. The TCP protocol can detect these data, find out data such as duplication and error, and repair it in time to ensure the integrity and correctness of the data.
4. Protect data security: The TCP protocol can provide a certain degree of security for the live broadcast platform, and protect the data transmitted by the live broadcast platform through encryption technology to prevent data from being stolen or tampered with.

3. Part of the code for the simple construction of the transmission control protocol TCP

import socket
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 8888)
server_socket.bind(server_address)
server_socket.listen(5)
print('服务器开始监听...')
while True:
    client_socket, client_address = server_socket.accept()
    print('收到来自 {} 的连接'.format(client_address))
    try:
        while True:
            data = client_socket.recv(1024)
            if data:
                print('收到客户端 {} 发送的数据: {}'.format(client_address, data.decode()))
                response = b'Received: ' + data
                client_socket.sendall(response)
            else:
                print('客户端 {} 断开连接'.format(client_address))
                break
    finally:
        client_socket.close()
server_socket.close()

Conclusion:

In this way, I have finished explaining the source code TCP protocol of the live broadcast platform. The transmission control protocol TCP guarantees the data transmission quality and user experience of the live broadcast platform. In a competitive digital media environment, providing a stable and reliable live streaming service is critical to attracting and retaining users.
