摘要： 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 load balancing the network traffic along the routing arcs based on traffic metrics obtained at the first and second ends of the routing arcs, including selectively sending a backpressure command to a first one of the routing arcs supplying at least a portion of the network traffic to a congested one of the routing arcs.

摘要： In one embodiment, a method comprises creating, in a computing network, a loop-free routing topology for reaching a destination device, the loop-free routing topology comprising distinct paths for reaching the destination device; generating a set of serialized representations describing the loop-free routing topology, each serialized representation describing a corresponding one of the paths; and propagating the set of serialized representations from the destination device to network nodes in the computing network, enabling the network nodes to establish loop-free label switched paths for reaching the destination device via the loop-free routing topology.

摘要： A method of automatically configuring a port of a network element comprises the steps of discovering information that identifies or describes a second network element that is coupled to a port of a first network element; associating the port with a port role definition selected from a plurality of port role definitions based on the discovered information; retrieving one or more configuration settings that are associated with the selected port role definition; and applying the one or more configuration settings to the port.
