Problems solved by technology

However, in the VS / DR mode, the load scheduling server and the RS need to have the same port, and the resulting problem is that the deployment and cascading of the load scheduling server and the RS are limited, and the load scheduling server cannot be a cross-port RS provides services and can only use a relatively flat network topology, which greatly limits the network topology

Embodiment Construction

[0034] A detailed description will be given below of embodiments of the present invention. Although the present invention will be described and illustrated in conjunction with some specific embodiments, it should be noted that the present invention is not limited to these embodiments. On the contrary, any modification or equivalent replacement made to the present invention shall be included in the scope of the claims of the present invention.

[0035] Some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

Abstract

The present invention provides a method and device for server load balancing. The source port in the reply data packet processed by the real server is changed to the port of the load scheduling server through the openflow flow table, thereby simply solving the problem of the difference between the load scheduling server and the real server. Port inconsistency problem. Since the reply data packet is sent directly to the client without going through the load scheduling server, the load on the device is reduced, and a large amount of data throughput can be performed with high performance.

Description

technical field [0001] The invention relates to network virtual technology and load balancing technology, in particular to a method and device for load balancing of virtual server clusters in a network virtual environment. Background technique [0002] Load balancing technology (Load Balance) is a technology that distributes load (work tasks) to multiple operating units for execution, so as to jointly complete work tasks. In network applications, it provides a cheap, effective and transparent method to expand the bandwidth of network devices and servers, increase throughput, strengthen network data processing capabilities, and improve network flexibility and availability. Among them, server load balancing is the most common. Due to the rapid growth of network data access traffic, while the growth of server processor speed and memory access speed is far lower than the growth of network bandwidth and application services, the server has become a network bottleneck. Therefore...
