Problems solved by technology

[0010] 1. The scheduling algorithm is too simple, and the appropriate algorithm is not selected through detailed analysis of the load characteristics of the Web Services engine
[0011] 2. Simply use the number of concurrent connections as the measure of server load, without considering the load of the server by comprehensive indicators
[0012] 3. The Gateway scheduler schedules from the application layer, and its performance is very low. When the number of requests is large, it is easy to become the performance bottleneck of the system.
[0013] 4. The single point of failure of the scheduler is not considered. All requests must first pass through the scheduler. Even when the entire system load is relatively light, if the scheduler is unavailable, the system will be paralyzed

Embodiment Construction

[0024] The present invention is aimed at load balancing on the middleware level.

[0025] Such as figure 1 As shown, it is a flowchart of Embodiment 1 of the grid load balancing method of the present invention, and specifically performs the following steps:

[0026] Step 101. When a grid node in an overloaded state receives a service request in compliance with the Simple Object Access Protocol specification sent by a client, the load transmitter set in the grid node performs load transfer of the service request;

[0027] Step 102, the load receiver of the grid node in the light load state actively obtains the service request, and executes the corresponding service;

[0028] Step 103, the grid node in the light load state returns the execution result of the service to the client.

[0029] This method is aimed at load balancing at the middleware level, shields the complexity of the underlying communication and the difference of the operating system, has better transparency, im...

Abstract

The invention relates to a method to balance grid load, which comprises: 1. the overloaded grid node receives user service request for SOAPS and sets its load transmitter to send load; 2. the load receiver of light-load grid node active acquires service request and executes service; 3. returns result to client. This invention method is fit to isomerous scientific research network, has well transparency, and improves system performance.

Description

technical field [0001] The invention relates to a method for balancing grid loads, in particular to a method for balancing grid loads based on bulletin board cooperation in a wide-area heterogeneous scientific research grid environment. Background technique [0002] With the development of network technology, since 1998, grid as a new type of wide-area resource sharing and collaboration technology has received more and more attention. Difficult to solve problems in the environment. In recent years, the wide application of Web service technology has made the service grid represented by Open Grid Service Architecture (OGSA for short) an important technical approach and development trend. [0003] The environment faced by the service grid has the following characteristics: [0004] 1. Large-scale cross-domain heterogeneous resource environment; [0005] 2. Service-based resource organization; [0006] 3. Computing-intensive scientific computing. [0007] In such an environ...
