Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

[0035] Such as figure 2 As shown, a load balancing method for a heterogeneous multi-application server system includes the following steps:

[0036] Step 1. Construct the system model including the weight matrix.

[0037] The system model is composed of weight matrix, probability matrix and resource matrix. The specific formula is as follows:

[0038] WP=R

[0039] in,

[0040] W is an N×M weight matrix, N is the number of ASs, M is the number of services, and the elements in the weight matrix are the conditional probability of a service triggering a certain AS, such as the element w in W i,j Trigger to AS for service j i The conditional probability of AS i For the i-th AS, the service ...

Abstract

The invention discloses a load balancing method for a heterogeneous multi-application server system. The load balancing method comprises the following steps: constructing a system model containing a weight matrix, wherein elements in the weight matrix are conditional probabilities of triggering a certain AS by a certain service; solving a weight matrix according to the system model; and executingservice triggering based on the weight matrix. The invention further discloses a corresponding system. According to the method, the weight matrix is solved through the system model, elements in the weight matrix are conditional probabilities for triggering the AS, service triggering is executed based on the weight matrix, and load balancing of the system is achieved.

Description

technical field [0001] The invention relates to a load balancing method and system for a heterogeneous multi-application server system, belonging to the technical field of electric power communication networks. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is a commonly used system supporting SoIP (service on Internet protocol, service on Internet protocol), which is a fusion technology of multimedia service and VoIP (Voiceover Internet Protocol, voice over Internet protocol). 3GPP defines it as the core network domain of multimedia communication. In an IMS network, an AS (Application Server, application server) plays a vital role in executing various multimedia services by processing service trigger packets and executing service logic. With the increase of the number of services and users, the existing AS load is getting larger and larger, which is the main cause of system errors. [0003] Therefore, many communication service compan...
