Data multicast implementation method, apparatus, and system

A data multicast implementation method, apparatus, and system are provided. In some embodiments, a transmission device receives a standby forwarding path establishment request, where the standby forwarding path establishment request includes a device identifier, has a destination address being an address of a multicast source device, and is used to request to establish a standby forwarding path between a multicast destination device identified by the device identifier and the multicast source device. In those embodiments, when determining, based on the device identifier in the standby forwarding path establishment request, that the transmission device is located on an active forwarding path between the multicast destination device and the multicast source device, the transmission device skips using the transmission device as a device on the standby forwarding path between the multicast destination device and the multicast source device, and skips forwarding the standby forwarding path establishment request.

Dynamic outroute load balancing and multicast

An apparatus, system, and method for balancing traffic loads on beam outroutes that contain both multicast and unicast traffic. An outroute is designated for supplying at least multicast traffic within a beam of a satellite communication system. Terminals interested in receiving the multicast traffic are moved to the designated outroute. Traffic loads on all outroutes within the beam, including the designated outroute, are compared to determine if variations in the traffic loads exceed a predetermined threshold. A load balancing routine is performed to redistribute the traffic loads on all outroutes, while excluding any terminal that is actively receiving the multicast traffic from the load balancing routine.

Generation of travel-related reporting messages

Travel-related-information messages (TRIMS) are received from one or more information sources, and information included in the messages is separated into a first (e.g. TPEG™) or second (e.g. TPEG+) group. A broadcast area to which the information included in the TRIMs is to be broadcast is determined. A further determination indicates that a subset of information assigned to the first group is to be reassigned to the second group. The subset of information is reassigned from the first group to the second group based on parameters associated with the broadcast area. The information included in the first group and the second group is delivered to one or more processing modules that generate a first TRIM reporting message using information included in the first group and a second TRIM reporting message using information included in the second group.

Node Protection for a Software Defined Replicator

According to certain embodiments, a system comprises one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations. The operations comprise selecting a primary node to replicate multicast traffic and forward the multicast traffic to a plurality of receivers, selecting one or more secondary nodes to provide node-level redundancy for the primary node, and providing the one or more secondary nodes with synchronization information that enables the one or more secondary nodes to replicate the multicast traffic and forward the multicast traffic to the plurality of receivers in response to the primary node becoming unavailable. Selecting the primary node is based in software.
