First Claim
Patent Images
1. A method comprising:
- storing, by a network device, an extended label forwarding information base that includes label switched path values that indicate paths to route traffic, wherein the paths include optimal and sub-optimal paths based on a shortest path metric;
receiving, by the network device, a traffic flow;
inspecting, by the network device, the traffic flow;
selecting, by the network device, a next hop and one of the label switched path values associated with the next hop based on the inspecting;
identifying, by the network device, one or more paths to route the traffic flow in accordance with one or more paths indicated by the one of the label switched path values; and
transmitting, by the network device, the traffic flow along the one or more paths toward a destination.

Abstract
A method, a device, and a storage medium provide for storing an extended forwarding information base that includes path values that indicate paths to route traffic, wherein the paths include optimal and sub-optimal paths based on a shortest path metric; receiving a traffic flow; inspecting the traffic flow; selecting a next hop and one of the path values associated with the next hop based on the inspecting; identifying one or more paths to route the traffic flow in accordance with one or more paths indicated by the one of the path values; and transmitting the traffic flow along the one or more paths toward a destination.
