Abstract
(EN) The invention is based on a highly efficient protocol for the delivery of high-quality multimedia communication services, such as video multicasting, video on demand, real-time interactive video telephony, and high-fidelity audio conferencing over a packet-switched network. The invention addresses the silicon bottleneck problem and enables high-quality multimedia services to be widely uses. The invention can be expressed in a variety of ways, including methods, systems, and data structures. One aspect of the invention involves a method in which a packet (10) of multimedia data is forwarded through a plurality of logical links in a packet-switched network using a datagram address contained in the packet (i.e., datagram address-based routing). The datagram address operates as both a data link layer address and a network layer address.
(FR) La présente invention est fondée sur un protocole hautement efficace de prestation de services de communications multimédia de haute qualité, tels que la multi-diffusion vidéo, la vidéo à la demande, la visiophonie interactive en temps réel et la visioconférence haute fidélité sur un réseau à commutation par paquets. L'invention permet de résoudre le problème de goulot d'étranglement de silicium et permet une large utilisation des services multimédia de haute qualité. L'invention concerne divers aspects, notamment des procédés, des systèmes et des structures de données. Un aspect de l'invention concerne un procédé dans lequel un paquet (10) de données multimédia est envoyé à travers une pluralité de liaisons logiques dans un réseau à commutation par paquets utilisant une adresse de datagramme contenue dans le paquet (c'est-à-dire, acheminement basé sur l'adresse de datagramme). L'adresse de datagramme fonctionne comme une adresse de couche liaison de données et comme une adresse de couche réseau.
