This invention describes a switched full-duplex Ethernet type communication network comprising at least one source subscriber equipment (13) and at least one destination subscriber equipment (14) connected to each other through at least one physical link through at least one switch and at least one virtual link (VL), which is the conceptual representation of a link from a source equipment (13) to at least one destination equipment (14), in which each equipment transmitting Ethernet frames comprises: means of segregation between virtual links and allocation of a passband for each virtual link, means of multiplexing virtual links on the physical link output from this equipment, each transmitted frame having a field that identifies the virtual link to which it belongs.
Switched full-duplex Ethernet type communication network comprising at least one source subscriber equipment (13) and at least one destination subscriber equipment (14) connected to each other through at least one physical link through at least one switch and through at least one virtual link (VL), which is the conceptual representation of a link from a source equipment (13) to at least one destination equipment (14), characterized in that each source equipment (13) that transmits Ethernet frames comprises:
Network according to any one of the previous claims, in which network redundancy is achieved which consists of doubling up the network, each subscriber having a connection to each of the two networks.
Process for implementation of a switched full-duplex Ethernet type communication network comprising at least one source subscriber equipment (13) and at least one destination subscriber equipment (14) connected to each other through at least a physical link through at least one switch and through at least one virtual link (VL) which is the conceptual representation of a link from a source equipment (13) to at least one destination equipment (14), characterized in that in a transmission service, an application (52) is allowed to access virtual links in transmission, this service being capable of multiplexing virtual links to a physical link (53) through an Ethernet interface (54), and for each virtual link sending the packets as a function of the passband allocated to it, and in that the time characteristics of the packets are checked in a passband protection service in the switch, for each incoming virtual link, and if the allowable characteristics are exceeded, the packets are destroyed to prevent a failure in a transmitter or a virtual link from compromising traffic in other virtual links leaving this switch.
