Abstract
Systems and methods for establishing path protection modes are provided. In one embodiment, a processor is configured to create a traffic policy that defines a Label Switched Path (LSP) configured to route data traffic in a unitary direction in a data plane of a telecommunications network. The LSP is configured to route the data traffic from a source router of an initial network domain to a destination router of a final network domain. The processor also creates a protection policy that defines one or more backup protection paths for routing the data traffic around one or more faulty nodes or links in a Segment Routing (SR) architecture of the telecommunications network. Furthermore, the processor distributes the traffic policy and protection policy in the telecommunication network via the Path Computation Element Protocol (PCEP).
