TCP/IP protocol suite application layer allow grouping nodes into logical networks according to similar characteristics, functionalities or social trends. Sometimes, it is useful, or necessary, to find a way to join those autonomous logical networks. This paper describes how a group of nodes, with the same role in a network, will establish logical connections with other nodes from other groups. This architecture allows sharing data, content and resources between different groups. The topology of logical connections, between nodes from different groups, changes depending on their processing, the number of connected nodes or node failures. It is scalable and fault-tolerant. The protocol and its management are described in detail. Simulation results for some cases are shown. The architecture has been developed to be applied to multiple types of logical networks (P2P file-sharing, distributed computing, CDNs and so on).
