A virtual network device includes a framing circuit that determines a virtual exit device associated with each input frame of a plurality of input frames based on a frame type for each input frame. A plurality of first encapsulated frames is formed based on encapsulation of the plurality of input frames. A plurality of transmit virtual ports, coupled to the framing circuit, determines next hops in a virtual network for the plurality of first encapsulated frames based on the virtual exit devices corresponding to the plurality of first encapsulated frames, and encapsulates the plurality of first encapsulated frames to form a plurality of second encapsulated frames. A transmit virtual switch selectively couples one or more transmit virtual ports to a network physical port based on whether a full signal from the one or more transmit virtual ports has been received by the transmit virtual switch.

Virtual network device

A virtual network includes a virtual entry device, a virtual exit device, and a communication channel that couples the virtual entry device to the virtual exit device in a web that lies between and interconnects a local router/switch with a remote router/switch device, where the virtual entry device and the virtual exit device have static forwarding tables which provide substantially improved performance.

Virtual network

A virtual circuit in a network device reformats one or more incoming data streams at a non-predetermined data rate into an outgoing data stream at a predetermined data rate, thereby allowing multiple data streams with non-predetermined data rates that are less than the predetermined data rate to be combined and output from a single network port.

Device, method, and system that virtualize a networks

A virtual network device increases the effective number of local physical ports by converting each of the local physical ports into a plurality of virtual local physical ports, and the effective number of network physical ports by converting each of the network physical ports into a plurality of virtual network physical ports.

A virtual circuit in a network device reformats one or more incoming data streams at a non-predetermined data rate into one or more outgoing data streams at a predetermined data rate, thereby allowing multiple data streams with non-predetermined data rates that are less than the predetermined data rate to be combined and output from a single network port, and a single data stream with a non-predetermined data rate that is greater than the predetermined data rate to be split and output from two or more network ports.
