Abstract:
1. A computer-implemented method comprising the following steps: monitoring, by one or more processors, a component link of a composite transport group associated with a label switched path established with an upstream label switched node; detecting a fault in the component link internally within the composite transport group without notifying the upstream label switched node, wherein the composite transport group provides a bundling of physical and/or logical component links representing a single logical interface; and determining whether traffic of the label switched path can be transparently rerouted to another component link of the composite transport group based on resource availability of the other component link and without externally notifying the upstream label switched node, wherein, if resources are available, the traffic is transparently rerouted to the other component link without externally notifying the upstream label switched node; and if resources are unavailable, the upstream label switched node is notified and reroutes the traffic from the composite transport group.
