摘要： A method of managing faults in a ring network may include configuring a ring network to be in a “horseshoe” topology by disabling a communications link from distributing media between a selected pair of adjacent nodes while allowing other communications or non-related media to continue to be distributed via the adjacent nodes. In the event of a failure, the disabled communications path may be re-enabled, and first or second backup communications paths may be employed, where the first backup communications path may use primary connections between adjacent nodes used for primary communications paths normally used to carry the media, and the second backup communications paths may use secondary connections between non-adjacent nodes. The disabled communications path may be dynamically moved in a logical or physical manner in an event of a communications link or node failure to maintain a “horseshoe” topology in the ring network.

摘要： A method or corresponding apparatus is employed for distributing media on a ring network. Multiple nodes and communications links are configured to distribute media in the ring network. Distribution of the media is disabled on a communications link between a selected pair of adjacent nodes in the ring network in a manner maintaining communications between the selected pair of adjacent nodes other than for distribution of the media. This configuration results in a “horseshoe” topology of the ring network with respect to the media, where distribution of the media on the ring network occurs in one or two downstream directions from head-end ingress node(s) on the ring network. Virtual Private LAN Service (VPLS) may be employed to transport the media. In an event of a link or node failure, the disabled link is enabled, allowing for continued distribution of the media with network recovery in a timeframe typically unobservable by an end user.
