Towards enabling peer-to-peer Grids

摘要

In this paper we propose a peer-to-peer (P2P) Grid comprising resources such as relatively static clients, high-end resources and a dynamic collection of multiple P2P subsystems. We investigate the architecture of the messaging and event service that will support such a hybrid environment. We designed a distributed publish-subscribe system NaradaBrokering for XML-specified messages. NaradaBrokering provides support for centralized, distributed and P2P (via JXTA) interactions. Here we investigate and present our strategy for the integration of JXTA into NaradaBrokering. The resultant system naturally scales with multiple Peer Groups linked by NaradaBrokering.
