Load balancing software architecture based on multi-core platform and method therefor

Abstract

The invention relates to a load balancing software architecture based on a multi-core platform and a method therefor, comprising the following content: 1) the multi-core platform and load balancing equipment are taken as framework elements, and a kernel thread is initialized for every network card on the load balancing equipment to be taken as the soft interruption routine of the network card; the kernel threads respectively process input and output of the corresponding network cards, and the kernel threads are independent; 2) an independent channel is set up for the information exchange between every two network card threads, and a group of bidirectional ring-shaped arrays can be set up in each channel and taken as a coupler between the multi-core platform and load balancing equipment; the ring-shaped arrays can maintain a writing point and a reading point and are respectively operated by two threads, so that the information exchange between the threads is not needed to be locked; 3) routing policy of balanced load of a server can be realized in the soft interruption routine of the input of the network card, and all work of an application layer is executed in a link layer. The multithreading lockless software architecture is adopted to realize the balanced load of the server; furthermore, the practice proves that the invention can remarkably improve the performance of the load balancing equipment.

Description

technical field [0001] The present invention relates to a load balancing software architecture and method, in particular to a multi-core platform-based load balancing software architecture and method applied in network load balancing. Background technique [0002] After the 1970s, thanks to the development of semiconductor technology, the cost of computers continued to decrease, and more and more people began to use computers, followed by the interaction of massive information. As the main carrier of information exchange, the network must also meet higher requirements, such as faster response time and greater traffic. Server clusters are introduced when a single server cannot fulfill a user's request. But the server cluster does not really solve the problem, but transfers the problem to the central device in the server cluster—the load balancing device. Load balancing devices are often located at the edge of the network, and are responsible for distributing user requests t...

Problems solved by technology

But how to distribute the operation of single-core CPU to multi-core CPU and effectively parallelize computing has become a new problem.

A general consensus has been obtained in the past experience of multi-thread computing, that is, all threads will access the same data structure, so that interlocking between threads will cause performance degradation

For a load balancing device, this performance degradation would be catastrophic
