As the development of hardware and software, large scale, flexible, distributed, secure and coordinated resource sharing has attracted much attention. One of the major challenges is to support distributed group-based resource management, e.g. interest-based organization, with resources/services classifiable. Although there have been some proposals to address this challenge, they share the same weakness of using either severs or super peers to keep global knowledge, and win good search efficiency at the expenses of the system scalability. As a result, such designs can not keep both the search efficiency and system scalability. To that end, this paper proposes a group-based distributed architecture. It organizes the nodes inside the groups by Chord protocol, a classical Peer-to-Peer (P2P) technology and it defines new communication protocol for nodes among different groups but removes servers/super peers for group management. Such a design keeps the resource classifiable property together with good system performance. The main characteristics of this architecture are highlighted by its convenience for group activity analysis, promising scalability, high search efficiency, as well as robustness. The experimental performance results presented in the paper demonstrate the efficiency of the design.
