More Information
Summary:A system and method is provided for seamlessly switching between different network access technologies without interrupting active network applications or sessions. A Network Access Arbitrator (NAA), which contains a virtual network adapter driver, resides between a Data Link Layer and a Network Layer of the standard OSI-7 Layer Protocol Stack for controlling necessary switching between different network access technologies. Since all network applications are controlled by layers residing on or above the Network Layer, all applications using network services provided by the Network Layer will continue their active network sessions or applications without disruption, as the NAA switches between different network access technologies.
