Peer-to-Peer computing with H2O and JXTA

H2O is Java-based, component-oriented, lightweight resource sharing platform for metacomputing. It allows deployment of services into container not only by container owners, but by any authorized clients or third parties. As a communication mechanism, H2O uses RMIX that is interoperable and extensible communication library. JXTA technology is a set of open protocols that allows any connected device on a network to communicate and collaborate in P2P manner. The main goal of this work is to build a uniform global computational network using H2O distributed computing framework and JXTA P2P technology. This computational network will give users new possibilities in building and utilizing of distributed computing systems, namely H2O kernels behind firewalls will be accessible and group management in JXTA will bring us a possibility of creating virtual groups of kernels, which enables dynamic ad-hoc created collaborations. In this thesis we present our solution of an integration of JXTA P2P technology with H2O framework. Our system, as there is presented, includes H2O kernels those are accessible using JXTA endpoints, automatic discovery of H2O kernels in P2P environment and monitoring capabilities of the network latency. Additionally we will show that an integration of the RMIX library, as an underlying communication substrate of H2O, with the JXTA technology leads to development of remote method invocation framework that can take benefits from acting in P2P environment. All the solutions presented in our thesis have already been implemented and tested. The results obtained while testing of the system are presented in one of the sections then.
