Abstract:
1. A method comprising: forming a core domain in a network, wherein the core domain comprises a device; and grouping a plurality of devices to form a plurality of domains within the network, wherein the core domain and the plurality of domains are formed in a hierarchical structure to form at least two data paths between two devices of the network, wherein the core domain is at a top of the hierarchical structure, wherein the at least two data paths carry data between the two devices in absence of a failure associated with a data path of the at least two data paths, and wherein a first data path of the at least two data paths is a redundant data path that carries data between the two devices in response to the failure associated with a second data path of the at least two data paths, and wherein data traffic flow is updated and self contained within only one domain of the plurality of domains in response to the failure and further if the two devices are within the one domain, and wherein data traffic flow is updated in two domains of the plurality of domains in response to the failure and further if the two devices are in two different domains and wherein remainder domains of the plurality of domains remain agnostic to the update to the data traffic flow.
