Abstract:
(EN) An apparatus comprising a plurality of district boundary bridges (DBBs) in a plurality of second network districts configured to couple to a plurality of core bridges in a core network district and to a plurality of end-stations in the second network districts via a plurality of intermediate switches in the second network districts; wherein the core bridges and the DBBs are aware of a plurality of Media Access Control (MAC) addresses of the DBBs but are not aware of Internet Protocol (IP) addresses and MAC addresses of the end-stations, and wherein the IP addresses of the end-stations are mapped in a directory service (DS) in the core network district to the MAC addresses of the corresponding DBBs in the corresponding second network districts of the end-stations.
(FR) L'invention porte sur un appareil comprenant une pluralité de ponts de frontière de district (DBB) dans une pluralité de seconds districts de réseau configurés pour établir un couplage à une pluralité de ponts centraux dans un district de réseau central et à une pluralité de stations d'extrémité dans les seconds districts de réseau par l'intermédiaire d'une pluralité de commutateurs intermédiaires dans les seconds districts de réseau. Les ponts centraux et les DBB ont connaissance d'une pluralité d'adresses de commande d'accès au support (MAC) des DBB mais n'ont pas connaissance d'adresses de protocole Internet (IP) ni d'adresses MAC des stations d'extrémité, et les adresses IP des stations d'extrémité sont faites correspondre, dans un service d'annuaire (DS) dans le district de réseau central, aux adresses MAC des DBB correspondants dans les seconds districts de réseau correspondants des stations d'extrémité.
