The Ethernet network comprises source subscriber and destination subscriber connected together by a physical link via a switch, and via a virtual link (VL). The virtual link is the conceptual representation of link between the source equipment and the destination equipment, including a system for segregation between the virtual links and the allocation of a pass band via the virtual link. <??>The switched full duplex Ethernet communication network comprises at least one source subscriber and at least one destination subscriber connected together by at least one physical link via a switch, and via a virtual link (VL). The virtual link is the conceptual representation of link between the source equipment and the destination equipment, including a system for segregation between the virtual links and the allocation of a pass band via the virtual link. It also includes a system for multiplexing the virtual links on the physical link issuing from this equipment. Each transmitted frame carries a field which identifies the virtual link to which it belongs. Each destination equipment comprises a device for subscribing to receive from at least one virtual link, assuring the segregation between virtual links. |
