Dynamic collection and analysis of network link performance indicators based on BGP-LS and telemetry

In the era of SDN/NFV technology, in order to meet the goal of cloud-network convergence and cloud to number conversion, this paper proposes a network link performance index collection based on BGP-LS and telemetry protocols to achieve second-level performance index collection, rapid network topology collection, topology change sensing, SRv6 path performance index sensing, etc., which realizes the automatic fault recovery capability from path monitoring, to fault detection, cause analysis, path re Optimization calculations, and the ability to send down the network to complete the automatic fault recovery of the path at the minute level.
