Abstract
Networks continually change in terms of physical, logical, and traffic loading. Determining efficient traffic flow from a content server to a subscriber is a difficult task, and slow network delivery can cause a subscriber to be dissatisfied with a service provider. A method or corresponding apparatus according to an example embodiment of the present invention selects the best physical or logical path via which devices should forward media content to end-user devices through multicast selection techniques, optionally in request or delivery directions, or both. The multicast selection allows devices to send streams over the most efficient channel detected in the network based on a criterion, such as latency. Upstream request multicast selection provides an ability to send requests faster, by sending them over multiple channels, and downstream multicast selection allows streams to be delivered faster in the downstream direction. Ultimately, shorter request times or faster delivery speed increases customer satisfaction.
