==PCE for BIER-TE Ingress Protection - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18487888 titled 'PCE for BIER-TE Ingress Protection

==Simplified Explanation==

The abstract describes a method implemented by a Path Computation Element (PCE) to control a Bit Index Explicit Replication Traffic/Tree Engineering (BIER-TE) domain. The method involves sending and receiving Path Computation Element Protocol (PCEP) messages between the PCE and network nodes in the BIER-TE domain. The PCEP messages contain specific type length values (TLVs) and capability sub-TLVs to indicate path setup types and capabilities of the network nodes, including the ability to detect adjacent node failures.

* The method involves using a PCE to control a BIER-TE domain.
* PCEP messages are sent and received between the PCE and network nodes.
* The first PCEP message includes a TLV indicating the path setup type capability.
* The second PCEP message includes a TLV with an ingress protection capability sub-TLV.
* The ingress protection capability sub-TLV contains a flag indicating the network node's ability to detect adjacent node failures.

Potential applications of this technology:

* Efficient control and management of Bit Index Explicit Replication Traffic/Tree Engineering (BIER-TE) domains.
* Improved fault detection and recovery in network nodes.
* Enhanced network resilience and reliability.

Problems solved by this technology:

* Simplifies the control and management of BIER-TE domains by using a Path Computation Element (PCE).
* Enables efficient detection of failures in adjacent network nodes.
* Facilitates faster fault recovery and network restoration.

Benefits of this technology:

* Improved network performance and reliability.
* Reduced downtime and faster fault recovery.
* Simplified network control and management.
* Enhanced network resilience and fault tolerance.


==Original Abstract Submitted==

A method implemented by a path computation element (PCE) configured to control a Bit Index Explicit Replication Traffic/Tree Engineering (BIER-TE) domain. The method includes sending a first path computation element protocol (PCEP) message to a network node in the BIER-TE domain. The first PCEP message includes a first path setup type capability type length value (TLV). The method further includes receiving a second PCEP message from the network node. The second PCEP message includes a second path setup type capability TLV comprising an ingress protection capability sub-TLV. The ingress protection capability sub-TLV contains a first flag. 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.
