Resource Monitoring System in SIG
SIG中的资源监控系统*

Spatial Information Grid is a wide area distributed information infrastructure. Discovering and sharing of spare resources is the key capability of this system, which relies on a resource monitoring system for gathering and distributing status information of resources. This paper presents a detailed implementation of a resource monitoring system in SIG: SIG-RMS. It follows the GMA framework and implements Local Monitoring Service(LMS) and Global Monitoring Service( GMS). This system adopts module-based designing strategies, which makes it flexibly configurable, scalable and high available. The paper introduces the architecture, Information Model and communication ways of the SIG-RMS, and describes its implementations, finally conclude its main characteristic.
