A method of using ring cache and ring queue to realize efficient concurrency of udp

Abstract

The invention relates to the technical field of UDP concurrency, in particular to a method for realizing efficient UDP concurrency by using a ring cache and a ring queue. The characteristics are as follows: Create a ring queue in the data receiving thread to store the client ID of the data to be returned, and create a sending ring buffer and a receiving ring buffer in the data processing sub-thread for receiving data and storing the data to be sent; data receiving The thread receives the data and checks whether there is a client ID that needs to return data in the ring queue at the same time. If there is a corresponding data processing sub-thread, the data in the ring buffer is sent out. The circular buffer of the present invention can provide mutually exclusive access to the buffer, so there is no need to add mutual exclusion protection between the data receiving thread and the data processing sub-thread, and it can be carried out simultaneously, thereby having good concurrent performance, and the circular buffer can be Better utilization of system memory resources.

Description

technical field [0001] The invention relates to the technical field of UDP concurrency, in particular to a method for realizing efficient UDP concurrency by using a ring cache and a ring queue. Background technique [0002] UDP, short for User Datagram Protocol, is a connectionless transport layer protocol in the OSI (Open System Interconnection, Open System Interconnection) reference model, providing transaction-oriented simple and unreliable information transmission services. [0003] Currently, there are three methods for UDP to achieve concurrency: [0004] 1. Loop mode: Create a socket, bind it to a port, and receive a request on this port, enter an infinite loop, in which the server accepts the next request from the client, processes this request, This response is then sent back to the client. This mode takes a long time to process requests and is relatively inefficient. We consider a service like file transfer, which requires a considerable amount of time to proces...

AI Technical Summary

Problems solved by technology

This is a commonly used method at present, but the biggest problem with this method is that the child thread will create a new socket and bind a new port to communicate with the client. If the client specifies to receive data from a certain port of the server, it will cause the client to Failed to receive
