Gridding service group establishing method and gridding service discovering method

Abstract

The build method for a grid service group comprises: the first GIS case sends query information for service group to multiple second GIS case; the latter returns response information; it generates service group member list and builds layered network connection; the first GIS case sends group-built information contained member list to second GIS case. The finding method for grid service comprises: GIS case receives service query request to decide whether the GIS belongs to the group when existing the service group with same service type; if yes, sends request to other members; or else, transmits the request to arbitrary member to send to other members. This invention improves query efficiency, and avoids the long response time and large network spending from flood in prior art.

Description

technical field [0001] The invention relates to a method for establishing a grid service group and a method for discovering a grid service, in particular to a method for establishing a service group for a service type initiated by any GIS instance in a grid environment and based on the established service Method for service discovery by group. Background technique [0002] Grid Information Service (GIS for short) is an important part of the grid environment. The grid implements resource sharing and collaborative utilization in a wide-area network environment. In order to dynamically establish a binding relationship between grid applications and grid resources, it is necessary to design grid information services to support resource (service) discovery and subsequent The state monitoring of resources (services) maintains relevant information of various entities participating in the grid (including personnel, resources, services, and hardware, etc.). In the service grid based...

Problems solved by technology

[0004] In the distributed information service architecture, the service discovery methods of the prior art have the following defects: Since GIS instances are often connected through some different relationships to form an unstructured graph, resources are searched on such a topology. (Service) Discovery must use a method called flooding to diffuse query requests along this graph

As the size of the graph grows, this search algorithm will inevitably bring about larger performance problems (ie, longer response time and larger overall network overhead).
