Abstract
An internetworking device and method which interconnects distant networks through an intermediary transport network, employing a bandwidth allocating mechanism to enable efficient and transparent LAN-to-LAN communication. A network interface unit provides communication interface functions to link with each network to be connected. Data traffic between the networks is observed by a traffic monitor and reported to a bandwidth allocation controller. A bandwidth resource database stores information on the usage of bandwidth resources. When a certain node in one network attempts to send data packets toward the other network, the bandwidth allocation controller dynamically allocates sufficient bandwidth resources to the requested connection, based on the reported data traffic and the information stored in the bandwidth resource database. With the allocated bandwidth, packets are transported to the destination under the control of a communication controller.
