Abstract: In one embodiment, a method comprises creating, in a computing network, a loop-free routing topology comprising a plurality of routing arcs for reaching a destination device, each routing arc comprising a first network device as a first end of the routing arc, a second network device as a second end of the routing arc, and at least a third network device configured for routing any network traffic along the routing arc toward the destination device via any one of the first or second ends of the routing arc; and causing the network traffic to be forwarded along at least one of the routing arcs to the destination device.

Abstract: In one embodiment, a method comprises creating, in a computing network, a loop-free routing topology comprising a plurality of routing arcs for reaching a destination network node, each routing arc comprising a first network node as a first end of the routing arc, a second network node as a second end of the routing arc, and at least a third network node configured for routing any network traffic along the routing arc toward the destination node via any one of the first or second ends of the routing arc, at least one of the first, second, or third network nodes are implemented as a ring-based network having a prescribed ring topology; and establishing loop-free label switched paths for reaching the destination network node via the routing arcs of the loop-free routing topology, the label switched paths independent and distinct from any attribute of the prescribed ring topology.

Abstract translation: 在一个实施例中，一种方法包括在计算网络中创建包括用于到达目的地网络节点的多个路由弧的无环路由拓扑，每个路由弧包括作为路由电弧的第一端的第一网络节点， 第二网络节点作为路由电弧的第二端，以及至少第三网络节点，被配置为经由路由选择电弧的第一或第二端中的任何一个路由沿着路由电弧的任何网络业务，至少 第一，第二或第三网络节点之一被实现为具有规定的环形拓扑的基于环的网络; 以及建立无循环标签交换路径，用于经由无环路由拓扑的路由弧到达目的网络节点，标签交换路径与规定的环形拓扑的任何属性独立且不同。
