CA 2279885
The invention provides for an E-Mux and a method for encapsulating/segmenting ATM cells into/from an Ethernet frame at the boundary between an ATM and an Ethernet network. An Ethernet end-station on the E-Mux is addressed using multiple MAC level identifiers, which are dynamically assigned according to the ATM virtual circuits which terminate on that end station, and have only transitory significance on the Ethernet. A unique ATM OUI identifies the frames carrying ATM-traffic.
Cette invention se rapporte à un multiplexeur E-Mux et à un procédé permettant d'encapsuler/segmenter des cellules MTA à destination/en provenance d'une trame Ethernet à la frontière entre un système MTA et un réseau Ethernet. Une station terminale Ethernet sur le multiplexeur E-Mux est adressée au moyen de multiples identificateurs de contrôle d'accès au support (MAC media control access), qui sont affectés dynamiquement en fonction des circuits virtuels MTA qui prennent fin au niveau de cette station terminale, et ne possèdent qu'une signification transitoire sur le réseau Ethernet. Un identificateur unique OUI (organizationally unique identifier) de MTA identifie les trames supportant un trafic MTA.
