Point-to-point (P2P) Internet connection establishment method uses Internet protocol (IP) server to send network user's temporary IP address to other users on network, and establishes connection to other users with handshake process

摘要

A network user (A) obtains a temporary Internet protocol (IP) address from an Internet service provider (ISP) and sends a search request to an IP server (X) to find IP addresses of other network users. The IP server sends the source user's IP address to each destination network user, and an establishing connection protocol establishes a point-to-point (P2P) Internet connection. The IP server provides and maintains a database for network users to register their present IP address and search for the IP addresses of other users. The establishing connection protocol is a handshake connection process e.g. Ethernet triple handshake process using transmission control protocol (TCP)/IP, and the established Internet connection may be either P2P or point-to-multiple point (P2MP).
