Patent ID: 6862285

Claim:
A method for a host computer communicatively linked to a local area network (LAN) and a virtual circuit network to handle communications between a LAN device and a virtual circuit interface device, the method comprising the steps of: intercepting a request sent to the virtual circuit interface device from the LAN device; extracting a network address of the LAN device from the request; forwarding the request to the virtual circuit interface device; receiving a virtual circuit response from a virtual circuit device through the virtual circuit interface device, the response including a virtual circuit identifier assigned to a virtual circuit connection; storing in a table a correlation between the network address from the request and the virtual circuit identifier from the response; and forwarding the response to the LAN device, wherein the virtual circuit interface device is a Remote Network Drive Interface Specification (RNDIS) device, the request is an RNDIS-compliant message, and the response is an RNDIS-compliant message.
