[0041] First refer to FIG. 3 , wherein FIG. 3 is a structural block diagram of a traffic distribution system according to the present invention. The traffic distribution system according to the present invention includes: a load detection module 302, which is used to periodically feed back the current load information of the target node to the distribution node; Processing capability; the target node screening module 306 is used to filter the target node to which the traffic will be distributed based on the calculation result of the processing capacity calculation module; the traffic distribution module 308 is used to distribute the traffic to the target node selected by the target node screening module and a flow receiving module 310, configured to receive and process the flow distributed by the flow distribution module.

[0042] Wherein, the processing capacity calculation module 304, target node screening module 306, and traffic distribution module 308 shown in FIG. 3 are l...

[0046] A second embodiment of the present invention will be described below with reference to FIGS. 6 to 10B.

[0047] As shown in Figure 6, the traffic distribution method according to the present invention includes the following steps: step S602, the target node feeds back the current load information to the distribution node; step S604, the distribution node calculates the current available load information of the target node according to the load information of the target node processing capability; step S606, the distribution node selects the target node to which traffic is to be distributed from multiple target nodes according to the result calculated in step S604; and step S608, the distribution node distributes the traffic to the selected node in step S606 target node.

[0048] Wherein, step S604 is performed according to the following expression:

[0049] γ=α(1-β)

[0050] In the above expression, α is the full-load processing capacity of the target node (the value ...

[0063] In the first embodiment according to the present invention, for the sake of illustration, it is assumed that the target node on the target side of the distribution system has a resource (for example, CPU resource), and the target node is processing power for calculations.

[0064] However, the present invention is not limited thereto. In particular, when there are multiple resources on a target node, generally speaking, the importance of various resources is different. Assuming that each resource Ri has its weight Vi, then the comprehensive processing power is Σ i = 1 k R i * V i .

Abstract

The invention relates to a flux distributing method based on weight, wherein it comprises that: step S602, target node feedbacks present load information to distributing node; step S604, distributing node based on load information calculates out the available processing ability of target node; step S606, distributing node based on the result of step 604 selects needed target node from several target nodes; and step S608, distributing node sends flux to the target node selected by step S606.

Description

technical field [0001] The present invention relates to the communication field, and more particularly, to a weight-based traffic distribution system and distribution method. Background technique [0002] In a system that requires multiple nodes to process services (such as a communication network), in order to increase capacity and improve processing performance, etc., it is often necessary to expand system processing nodes. The expansion of nodes enables the processing that was originally concentrated on one node to be distributed to multiple nodes, so as to reduce the impact on the performance of certain (some) nodes. [0003] As shown in Figure 1A, a system such as a communication network is generally divided into two levels: a distribution side and a target side. The distribution side distributes the service traffic according to certain principles to complete the service distribution function; the target side receives the traffic and processes it. [0004] At the same...
