Latest Patents

Horowitz holds a patent for a "Virtual Network Architecture." This invention describes a network infrastructure that includes various connective devices such as routers, repeaters, and bridges. The architecture is designed to form a communication network for multiple end nodes. In this system, message packets originating from an end node are assigned an input virtual network and workgroup identification at the port where the packet enters the network. The assigned input information is then compared at each port from which the packet can exit. If there is a mismatch between the input and output virtual network information, the packet is prohibited from exiting that port. Additionally, even if there is a match, there must be a corresponding match between at least one bit of the input workgroup identification and the output workgroup identification for the packet to exit the port.
