P2MP TREE CONNECTIVITY DETECTION METHOD, DEVICE, AND SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18156996 titled 'P2MP TREE CONNECTIVITY DETECTION METHOD, DEVICE, AND SYSTEM

Simplified Explanation

The patent application describes an application that detects connectivity in a Point-to-Multipoint (P2MP) tree in a Segment Routing (SR) domain. The method involves a first node in the P2MP tree determining the next-hop node based on replication branch information and sending a request message to the next-hop node for connectivity detection.

  • The application provides a method for detecting connectivity in a P2MP tree in an SR domain.
  • The method involves a first node in the P2MP tree determining the next-hop node based on replication branch information.
  • The first node then sends a request message to the next-hop node for connectivity detection.
  • The request message includes a segment identifier (SID) of the next-hop node and a first identifier indicating that the message is for connectivity detection.

Potential Applications

  • This technology can be applied in network management systems to ensure connectivity in P2MP tree structures.
  • It can be used in large-scale networks where efficient detection of connectivity is crucial for maintaining network performance.

Problems Solved

  • The application solves the problem of efficiently detecting connectivity in P2MP tree structures within an SR domain.
  • It provides a method for the first node to determine the next-hop node and send a request message for connectivity detection.

Benefits

  • The method described in the patent application allows for efficient detection of connectivity in P2MP tree structures.
  • It improves network management by ensuring the stability and performance of P2MP tree connections.
  • The use of segment identifiers and request messages enables accurate and targeted connectivity detection.


Original Abstract Submitted

This application provides a P2MP tree connectivity detection method, a device, and a system. The method is applied to SR domain. The SR domain includes a P2MP tree. The P2MP tree includes a first node. The first node is a root node or an intermediate replication node of the P2MP tree. The method includes: The first node determines a first next-hop node of the first node based on replication branch information; and the first node sends a first request message to the first next-hop node. The first request message includes a segment identifier SID of the first next-hop node. The first request message includes a first identifier. The first identifier indicates that the first request message is for connectivity detection.
