Problems solved by technology

The fourth-layer load balancer can solve the problem of performance bottleneck, but it can only provide an upstream entrance, and cannot increase the upstream network bandwidth; Trunking technology can solve the problem of network bandwidth, but the physical port of Trunking must be connected to the same service node , does not improve processing performance

Embodiment approach

[0038] 1. Bind multiple physical ports to provide a single virtual IP and virtual MAC to the outside world.

[0039] (As shown in accompanying drawing 1) distributor of the present invention provides a virtual IP address and MAC address internally, provides a single access address for the client, when receiving ARP packet, directly virtual MAC is returned to the user . The IP address and MAC address can be set through a dedicated control interface or a network login to a single address traffic distributor. The number of bound physical ports is half of the total number of physical ports of the device by default. The purpose is to maintain the balance of network traffic entering and leaving the device. Of course, the number of bound physical ports can also be adjusted according to user needs.

[0040] 2. (As shown in Figure 3) Calculate the client IP address according to the Hash algorithm to obtain the Hash value, and forward the data packets with different Hash values ​​to di...

Abstract

The invention provides a single address flow sorter of group network. The sorter binds several physical terminals into a virtual physical terminal to extend the upstream flow, and allocates network flow to different processing joints according to the IP address of client terminal and upgrade the process ability. The data pack applying the IP is allocated with a different physical terminal, the process is realized with ASIC technology, the flow classification accordance is to work out Hash value to the client terminal IP address, because the data of the same user is allocated to the same physical terminal, thus it can provides continuous service to the joint connected to the physical joint.

Description

1. Technical field [0001] The invention relates to the computer field, and is a single-address flow distributor for constructing a cluster network with high availability and high scalability. 2. Technical background [0002] The rapid growth of online activities has greatly increased the number of visits to web servers, causing many key parts of the network to become performance bottlenecks or bandwidth bottlenecks. At present, the method of trunking (link aggregation) of the fourth layer load balancer or the physical port of the switch is generally used to solve this problem. The fourth-layer load balancer can solve the problem of performance bottleneck, but it can only provide an upstream entrance, and cannot increase the upstream network bandwidth; Trunking technology can solve the problem of network bandwidth, but the physical port of Trunking must be connected to the same service node , cannot improve processing performance. ...
