PCE for BIER-TE Ingress Protection

A non-transitory computer readable medium comprising a computer program product for use by a network node, the computer program product comprising computer executable instructions stored on the non-transitory computer readable medium that, when executed by one or more processors, cause the network node to:

• send a first path computation element protocol (PCEP) message to the network node in a Bit Index Explicit Replication Traffic/Tree Engineering (BIER-TE) domain, wherein the first PCEP message includes a first path setup type capability type length value (TLV);
• and
• receive a second PCEP message from the network node, wherein the second PCEP message includes a second path setup type capability TLV comprising an ingress protection capability sub-TLV, wherein the ingress protection capability sub-TLV contains a first flag, and wherein the first flag is set to a first binary value to indicate that the network node is able to detect a failure of an adjacent network node.
