Virtual network addresses

This invention describes a special network card that can act like many different network devices simultaneously. It does this by creating several "software network devices," each with its own unique network address. When data arrives for one of these virtual devices, the network card ensures it's delivered to the correct software device.

Why it matters: Filed before widespread server virtualization and cloud computing, which now heavily rely on virtual network interfaces. Modern specialized network cards (SmartNICs) perform these functions to accelerate virtual networking.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom network card hardware, embedded software logic.
