Abstract
Multi-Protocol Label Switched (MPLS) traffic is re-routed to an alternate, Label Switched Path (LSP) to bypass a failure along a primary LSP, even though the failure occurs at or along an ingress section of an LSP, while associating an original IP address to the alternate path. Failures are also detected farther downstream outside an ingress section. When this occurs, MPLS traffic is re-routed to an alternate LSP which maintains the same quality of service as an original primary path and includes other network devices which are not a part of the primary path (except for the network device and a destination network device). The techniques require less resources than existing techniques.
