Abstract

See full text

A non-standardized private computer network (20) uses a tunnel engine (50, 58) to allow a computer (12-16) on one private computer network with non-standard address to communicate over a standardized carrier network (32) with a computer (22-26) on the same private computer network. The tunnel engine includes a local router (52) and rule check engine (54) in the private computer network and a remote router (56) in the standardized carrier network. The rule check engine performs rule checks to determine proper encapsulation and routing of the message. The message is encapsulated with a standardized address of endpoints of a tunnel through the carrier network corresponding to the desired destination. With a standardized address, the encapsulated message packet passes through the tunnel and arrives at the boundary of the destination private computer system. The encapsulation is removed and the message is routed to the destination computer.
