    摘要: Systems and methods are provided for a multi-floor and/or multi-site distributed switch. As video applications such as “video on demand” (VoD) start to become more used by the general public and desire for combining networks capable of carrying voice, data, internet and video increases, service providers are requiring broadband networking capabilities that require new scaleable infrastructure solutions. Existing network technologies are not flexible enough to deliver broadband traffic required for each floor of a multi-floor network data center (NDC) or multiple NDCs connected in a ring. Conventional solutions involve direct cabling from each floor to a common room on one floor of the site. Embodiments of the present invention provide for a distributed switch including a plurality of switching elements on different floors/sites that is non-blocking under defined traffic conditions. By understanding some key dynamics of the NDC, including the attributes of the services being implemented and what functionality exists on each floor, the distributed switch is designed to handle a capacity much greater (>>3×) than independent monolithic switching elements on each floor joining in a “meet-me” room.

    摘要: A method and system for protecting a service available on a broadcast domain. A sub-domain is established within the broadcast domain. The sub-domain includes a group of nodes used to provide a communication path to the service. A primary sub-domain maintenance association and a back-up sub-domain maintenance association are monitored. The primary and sub-domain maintenance associations are a set of primary and back-up paths, respectively, representing connectivity between nodes acting as edge nodes in the sub-domain. A fault is detected within the primary sub-domain maintenance association and a switch to the back-up sub-domain maintenance association occurs.
