Problems solved by technology

An important shortcoming of this fault-tolerant processing method is that all established TCP connections will be lost, which will cause inconvenience and even loss to users.
The disadvantage of this approach is that it costs a lot
Especially when the number of connections increases and the state changes frequently, multicast can cause a heavy burden on the network
In addition, this method requires a dedicated backup node to perform extremely low-cost backup work, and cannot share scheduling tasks for the scheduler, so resources are wasted, which is especially prominent for smaller-scale cluster server sites

Embodiment Construction

[0044] The present invention can be divided into two parts from the perspective of software method and hardware: an integrated two-machine structure and a two-machine cooperative scheduling method.

[0045] The integrated dual-computer structure is to place two sets of computer systems with the same configuration side by side on a backplane, such as figure 1 shown. The computer system here is composed of CPU, motherboard, memory, DOM (Disk On Module) electronic disk, power supply, fan and other peripheral equipment. Among them, the motherboard adopts an integrated method, with a graphics card and two network interface cards embedded. DOM is an electronic disk that uses an integrated device (Integrated Devices Electronics, IDE) interface. It uses advanced integrated circuits as memory, unlike traditional hard disks that use magnetic media as memory. For systems with low capacity requirements, it can reduce costs; it also has the advantages of no loss of data after power failu...

Abstract

A load balancing scheduling method with TCP connection fault tolerance function, the method adopts an integrated dual-machine cooperative structure, uses a backplane to place two sets of computer systems with the same configuration side by side, so that the dual-computer system forms a whole. The two machines are set to the same IP address and physical address, receive external IP packets at the same time, and filter the IP packets according to different rules at the link layer to distribute network requests. For their respective network tributaries, the two machines use the Linux virtual server to schedule requests. At the same time, the dual-machine system monitors and backs up each other, so that when a machine fails, the other machine can smoothly take over its work. This takeover process ensures that the client's connection will not be interrupted. When the faulty machine returns to normal, it can share the scheduling task again by negotiating with another machine. Compared with other proposals, the present invention has the advantages of high reliability, low cost, high efficiency, small volume and the like.

Description

technical field [0001] The invention belongs to the field of computer applications, and in particular relates to a load balancing scheduling method with a TCP connection fault-tolerant function. Background technique [0002] Today's computer technology has entered the network-centric computing period, and a large number of applications are carried out around the network, which puts forward higher and higher requirements for the performance and reliability of the server. For example, with the rapid development of the Internet and the rapid growth of users, the more popular Web sites will not be able to process user requests in time due to the sharp increase in the number of visits, causing users to wait for a long time or even be rejected, which greatly reduces the quality of service . For CPU-intensive applications, such as Web services with Common Gateway Interface (CGI) and database operations, the server performance bottleneck problem is more prominent. In addition, wit...
