20 results about "Hole punching" patented technology

Hole punching (or sometimes punch-through) is a technique in computer networking for establishing a direct connection between two parties in which one or both are behind firewalls or behind routers that use network address translation (NAT). To punch a hole, each client connects to an unrestricted third-party server that temporarily stores external and internal address and port information for each client. The server then relays each client's information to the other, and using that information each client tries to establish direct connection; as a result of the connections using valid port numbers, restrictive firewalls or routers accept and forward the incoming packets on each side.

Communication methods, communication systems, communication devices, and communication programs

The process involves the first terminal 1a under the first NAT router 2a and the second terminal 1b under the second NAT router 2b obtaining each other's public keys, both terminals calculating a common port number P using a derivation function based on each other's public keys, the first terminal sending a packet requesting a connection via the common port number P to the second NAT router at first time intervals, and the second terminal sending a packet requesting a connection via the common port number P to the first NAT router at second time intervals. This eliminates the influence of port translation in the NAT routers, enabling successful asynchronous hole punching and establishing a secure P2P connection.
