Abstract

The next generation grid systems exhibit a strong sense of automation. To address such a challenge, Our previous work has viewed a grid as a number of interacting agents and applied some key mechanisms of natural ecosystems to build a novel grid middleware system, where a collection of distributed agents are searched, assembled, organized and coordinated to emerge desirable grid services. All these actions of agents depend on an effective communication scheme. In this paper, we design a flexible communication scheme to implement the complicated coordination strategies among agents, including a RMI-IIOP-based transport mechanism, an ecological network communication language, and an ecological network interaction protocol from low to high implementation strategy. To test our hypothesis that grid services with desired properties can emerge from individual agents via our communication scheme, simulations of resource discovery service are carried out. The results prove that the scheme can well support this kind of bottom-up approach to build desirable services in grid environments.
