Title (EN) MULTICAST TO UNICAST TRAFFIC CONVERSION IN A NETWORK
(FR) CONVERSION DU TRAFIC MULTIDESTINATION EN DESTINATION UNIQUE DANS UN RESEAU
Abstract: front page image
(EN)Techniques are described for converting multicast traffic to unicast traffic at an optical network terminal ONT (28) on a passive optical network PON (10). A traffic conversion technique, in accordance with the invention, involves formatting a multicast frame of a multicast packet stream transmitted to the ONT to include a MAC destination address of the station requesting the multicast packet stream. By including the MAC destination address of the specific station to which the multicast packet stream is to be transmitted, the multicast packet stream is effectively converted to unicast traffic stream. The traffic conversion techniques are designed to avoid overloading stations on a subscriber Ethernet network that are not participating in a multicast group by sending multicast traffic to the stations requesting the multicast traffic. In this way, the traffic conversion techniques allow common equipment to be used while not overburdening non participating stations with traffic that needs to be discarded.
(FR)L'invention porte sur des techniques de conversion d'un trafic multidestination en un trafic à destination unique au niveau d'un terminal (28) de réseau optique sur un réseau optique passif (10). Selon cette invention, une technique de conversion de trafic consiste à formater une trame multidestination d'un flux de paquets multidestination envoyé au terminal de réseau optique pour inclure une adresse de destination MAC de la station demandant le flux de paquets multidestination. En incluant l'adresse de destination MAC de la station spécifique à laquelle doit être envoyé le flux de paquets multidestination, ce flux de paquets multidestination est effectivement converti en un flux de trafic à destination unique. Les techniques de conversion de trafic sont conçues pour éviter la surcharge des stations sur un réseau Ethernet d'abonnés qui ne font pas partie d'un groupe multidestination en envoyant le trafic multidestination aux stations demandant le trafic multidestination. De cette manière, les techniques de conversion de trafic permettent d'utiliser un équipement commun sans surcharger des stations non participantes par le trafic devant être supprimé.
