Personal Grid Running at the Edge of Internet

The common Grid systems are running on the backbone of Internet. These high performance computing environment provide a high scalable, high reconstructive Grid services in a C/S mode, while more and more Grid applications require a P2P liked infrastructure for personal intercommunication, resources sharing and collaborative work. Personal Grid, we proposed in VEGA Grid project of ICT, would establish such kind of platform to facilitate the messages transmitting and resources sharing for the end Grid users who are using Grid at the edge of the Internet. The core protocol of Personal Grid gives attentions to security, network bandwidth usage and real time requirements. The Personal Grid running environment is very similar to P2P system; it inherits some advantages of P2P system and enhances some parts for Grid usage such as security protection of mandatory access control.
