Abstract: When a first device is establishing a point-to-point connection with a second device, a server provides connection instructions for assistance. The connection instructions define multiple connection flows. When the connection instructions are received, the first device attempts a first connection flow under a priority order. If failed, another connection is tried by the first device. The server monitors connection status and adjusts the connection instructions according to statistics and circumstances.

Abstract: A searching system, searching method and P2P devices for a P2P device community are provided. An online server connects to a content management server and a P2P device community, respectively. The content management server includes a search engine and an index database, and each of the P2P devices of the P2P device community is provided with an indexed data and a weighted data. The index database is recorded with the indexed data associated with each of the P2P devices of the P2P device community, and the search engine searches the index database to generate a search result and then generates a weighted and sorted search result based on the weighted data, thereby achieving the object of searching important file data in the P2P device community.

Abstract: A remote information communication system comprises an administration server, at least one linking server and at least one remote device. The linking method of the remote information communication system comprises steps of: the administration server authenticating the remote device and linking server; the proximal device requesting the administration server to find out a specified remote device; the administration server responding an address of the linking server for establishing a link with the specified remote device; the proximal device linking with the linking server through the address responded from the administration server to find out the specified remote device via the linking server; and the linking server establishing a link between the proximal device and the specified remote device.
