Abstract: 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.

Abstract: A particular method includes measuring port usage data related to each of a plurality of physical ports associated with a link aggregation group. A bandwidth requirement of a requested media stream is estimated and added to a traffic load at each of the plurality of physical ports to produce an estimated total traffic load of each of the plurality of physical ports. When the requested media stream includes non-video data, the requested media stream is sent to a destination device via a physical port that selected in accordance with a static bandwidth allocation. When the requested media stream includes video data, the requested media stream is sent to the destination device via a least loaded physical port that is dynamically identified based on the estimated traffic loads of each of the plurality of physical ports.
