摘要： A method to perform dynamic source selection within an IP multicast network is performed at a designated router of an IP multicast network. At the designated router within the IP multicast network, a first source of a multicast group is selected to be forwarded to a receiving host or multiple receiving hosts. The first source is monitored to automatically detect when the first source exhibits a predetermined characteristic. At the designated router, responsive to the detection that the first source exhibits the predetermined characteristic, a second source of the multicast group is automatically selected to be forwarded to the receiving host or hosts. The method also supports automatic selection of all normally operating sources and forwarding of the traffic of such sources or channels to the receiving hosts or hosts.

摘要： A method is disclosed that includes receiving a data packet at a first video distribution hub via a first link. The method also includes determining whether a second link has failed, wherein the first video distribution hub communicates with a second video distribution hub via a primary network path that includes the second link. When the second link has failed, a backup network path to send the data packet, or a copy thereof, to the second video distribution hub, is determined based on data stored at the first video distribution hub. The method also includes sending the data packet, or the copy thereof, to the second video distribution hub via the backup network path, wherein the backup network path does not include the second link.

摘要： The present disclosure is generally directed to systems and methods associated with data communications. In a particular embodiment, a method for use of multi-protocol labels switching (MPLS) encapsulation with control word communicated over a distributed computer network is disclosed. The method includes providing MPLS virtual circuit label with the control word associated with a data packet selected from one of a customer data packet and an OAM data packet, and communicating the MPLS packet with control word and the data packet over the distributed computer network.In another embodiment, a method of handling a data packet within a computer network is disclosed. The data packet is either an unknown unicast, multicast, or broadcast packet. The method includes encapsulating the packet into a multi-packet label switching label and a control word, the control word having a source site identity and a multi-cast identity; and distributing the packet to a plurality of sites within the computer network.
