1. A virtual network, comprising:
a virtual entry device; and
a virtual exit device to be coupled to a remote router/switch,
wherein the virtual entry device is configured to:
determine the virtual exit device from a header of a frame associated with the virtual entry device;
encapsulate the frame to form a first encapsulated frame;
determine a next hop for the first encapsulated frame from an identity of the virtual exit device;
encapsulate the first encapsulated frame to form a second encapsulated frame, the second encapsulated frame having a field that identifies a next hop for the second encapsulated frame, and a field that includes the first encapsulated frame; and
combine the second encapsulated frame with other second encapsulated frames from a plurality of sources, to form a sequence of second encapsulated frames, for transmission of the sequence of second encapsulated frames.
