CROWN Node Server: An Enhanced Grid Service Container Based on GT4 WSRF Core

WSRF core is an open-source implementation of grid service container in Globus Toolkit 4 (GT4). However, GT4 WSRF core is far from a full-fledged grid service container. Basing on the Globus work, we develop CROWN Node Server, an enhanced grid service container. Besides basic functions of a WSRF grid service container, CROWN Node Server encompasses features including remote & hot service deployment with trustworthiness, monitoring, logging and management, etc, which are of paramount importance to build applications using service grid technologies. CROWN Node Server has been successfully adopted and widely deployed in CROWN grid environment to support a wide range of service grid applications. We conduct comprehensive experiments to evaluate the performance of Node Server, and the comparing results with GT4 WSRF core are presented as well
