摘要： Un procédé est dédié à la transmission, via une infrastructure (CN, RA) de transmission par voie d'ondes, comprenant des stations de base (Ni) contrôlées par des noeuds (CR), d'un contenu, agencé en une couche de données de base et une couche de données d'augmentation. Ce procédé comprend les étapes suivantes :
- envoyer à des noeuds (CR), contrôlant des stations de base (Ni) choisies constituant un premier ensemble, une première requête demandant l'établissement d'une session de transmission d'un premier flux relatif à un premier groupe de couche(s) du contenu,
- déterminer un second ensemble de stations de base parmi les stations de base (Ni) du premier ensemble, et
- envoyer aux noeuds (CR) contrôlant stations de base (Ni) de ce second ensemble une seconde requête, demandant l'établissement d'une session de transmission d'un second flux relatif à un second groupe de couche(s) du contenu, distinct du premier groupe.

摘要： A system, apparatus, article of manufacture, and method provides one or more distributed convergence nodes referred to as 'Supernodes', each of which is embodied as a functional technology component within an application that automatically determines whether said component should become 'active' and assume the responsibility of forwarding IP multicast data present on a LAN (which supports IP multicast communication) to a 'Routing Supernode' via a WAN (which does not support IP multicast communication). The Routing Supernode, in turn, is responsible for forwarding that traffic to other Supernodes present on other LANs. The traffic sent to and from the Routing Supernode is sent via unicast communication. All Supernodes are responsible not only for forwarding traffic present on their respective LAN across the WAN to a Routing Supernode, but they are also responsible for forwarding traffic received over the WAN from the Routing Supernode onto their own respective LANs. An election process determines which device in a LAN is to operate as a SuperNode.

摘要： The invention relates to the distribution of broadband multimedia streams in WiFi connections and provides a solution based on encapsulation, provided by a mechanism for tunneling multicast IP traffic by means of unicast IP tunnels. These tunnels are defined at the IP level and can be set up, as appropriate, between the provider access equipment and the set-top box (STB), or between the user's WiFi modem-router and the set-top box (STB) of the digital television distribution service.

摘要： The present invention provides a method of transmitting multicast and broadcast content in a mobile access network, the mobile access network comprising: at least one multicast-broadcast service zone with at least one Base Station, a Multicast-Broadcast server for each one of the multicast-broadcast service zones, the mobile access network coupled to a content distribution network, the content distribution network comprising a content server coupled to an IP multicast network, the content server being adapted for multicast and broadcast transmission, the method comprising the steps of: sending a first join request using a membership protocol for a multicast group from a Multicast-Broadcast server to the content distribution network; sending a second join request using the membership protocol and sending a first multicast IP packet from the multicast/broadcast content server to the multicast-broadcast server using a first multicast routing protocol. The method further comprises: encapsulating the first multicast IP packet into a second multicast IP packet; sending the second multicast IP packet to the local multicast group of the multicast-broadcast service zone using a second multicast routing protocol.

摘要： There is provided a packet distribution control method for performing multi-cast communication in a network environment containing networks compatible and not compatible with IP multi-cast. In the packet distribution of the multi-cast communication, each end node checks whether IP multi-cast communication is possible or not possible with another end node. Each end node uses IP uni-cast for packet distribution to another end node which cannot communicate by the IP multi-cast alone.

摘要： A method for implementing multicast in the MAC in MAC network, which method enables the operator's backbone network device to support the multicast copy ability based on the private network user, and allows the public network, which supports the MAC in MAC Layer 2 backbone network, to have the full multicast ability, the inventive method adds into the PBB the correspondence of the multicast address between the private network and the public network as well as the multicast forwarding tables in each network equipments, copies and sends downward the multicast messages stage by stage, so that the multicast messages are sent downward in accordance with the typical multicast tree structure, thereby avoiding the huge waste of the bandwidth due to the multicast copy.

摘要： A mobile station (303) provides seamless mobility across multicast domains for communicating with a multicast group (109) in a telecommunication system (300) that includes a home domain (102) and a visited domain (302). The mobile station (303) includes a local source address (324) and a home address (322). The mobile station (303) also includes a domain detector (305) for detecting a current domain of the mobile station (303), a comparator (307) for comparing the current domain of the mobile station with a previous domain of the mobile station (303) to generate a comparison result; and a multicast mode switch (326) coupled to the comparator (307) for switching between the local source address (324) and the home address (322) to select a source address for communicating with the multicast group (109) as a function of the comparison result.
