Embodiment 1

[0028] Such as figure 1 As shown, this embodiment provides an IOCP mechanism, which includes the following steps:

[0029] S1: Start the application, create a main thread for processing socket connection transactions and N worker threads for processing asynchronous I / O requests, and register an I / O completion callback function when creating worker threads;

[0030] S2: Store the created worker threads in the thread pool in a stack;

[0031] S3: Initiate an I / O request and establish a Socket connection. After the main thread completes the connection, it associates Socket with IOCP and puts the I / O request into the first-in first-out FIFO message queue. The worker thread processes the I / O request, and the main thread does Be freed to continue listening for new I / O requests;

[0032] S4: The thread pool uses a first-in-last-out FIFO method to schedule one of the idle worker threads among several worker threads to process I / O requests;

[0033] S5: After the called worker thread completes ...

Abstract

The invention discloses an IOCP mechanism and an Internet of Things communication acceleration system based on an eFPGA and IOCP, and relates to the technical field of network communication. The acceleration system comprises an Internet of Things server, a network communication acceleration device and various application scene terminals. The network communication acceleration device comprises a memory, an eFPGA and a plurality of network interfaces. The memory is used for providing a data storage program for the network communication acceleration equipment. The network interface is used for realizing communication with an application scene end. The eFPGA is used for realizing a plurality of IOCP examples in parallel; processing the data of the corresponding network interface. Load balancing is achieved in an application system through the eFPGA technology, the parallel execution capacity is achieved instead of serial execution instructions such as a CPU, the communication speed is increased, the data processing bandwidth is increased, and the multiple FPGAs are utilized, so that the access requirement of a larger amount of Internet of Things data can be met.

Description

Technical field [0001] The invention relates to the technical field of network communication, and more specifically to an IOCP mechanism and an IoT communication acceleration system based on eFPGA and IOCP. Background technique [0002] In the digital age, especially with the advent of 5G, network communication is very important, and network communication is an important technical means to connect various devices together. As the scale of communication becomes larger and larger, the design of network center nodes becomes very important because it is a bottleneck that affects communication efficiency. [0003] The I / O Completion Port (IOCP) is a kernel-level completion port introduced in Winsock 2.0. It is a mechanism for efficiently processing various I / Os, because it is providing massive I / O requests. When serving, it has excellent performance when dealing with a large number of client frequent connections and frequent sending and receiving of small data packets. Compared with or...
