Uniform resource name resolution based on VIRGO P2P network

When more and more equipments are connected into Internet such as 3G mobile, and the next generation networks such as 4G mobile will be deployed in the future, uniform resource names as global unified identifications are become important. Uniform resource names identify the things to avoid the conflict names among those huge amounts of objects in the Internet. However, people may want to map more information through the names. Because there are huge amounts of names, how to resolve the names into other information such as locations becomes an important issue. Client/server model can not work well to resolve the names due to traffic load and centralized balance. P2P is considered as an approach to solve the problem. In this paper, we propose a VIRGO-based P2P solution, in which the peers (registries) are virtually grouped by namespaces of uniform resource names. They construct n-tuple overlay virtual hierarchical tree overlay network according to their namespaces. With cached addresses of peers, the overload of traffic in tree structure can be avoided. This proposal supports flexible resolutions by a SQL-like query statement.
