AI Technical Summary

Technical Problem

Traditional OAM measurement methods in satellite networks cannot accurately locate faulty nodes, resulting in low network management efficiency. Furthermore, measurement data is easily fragmented and lost, making it impossible to reconstruct performance changes before link failure.

Method used

A distributed context saving mechanism is adopted, which generates and stores context fragments locally on the node, including measurement results, node identifier, probe session ID and path signature. The control side splices together the complete performance profile and designs a node disconnection compensation, context deduplication and time sequence verification mechanism.

Benefits of technology

It enables precise fault location and performance trend analysis in satellite networks, improving network management efficiency and enhancing system robustness and engineering feasibility.

Abstract

This invention discloses an OAM measurement method, apparatus, device, and system suitable for satellite networks. The method, executed on the control side, includes: collecting context fragments stored locally by multiple nodes along the measurement path. These context fragments are generated and stored locally by the nodes after initiating an OAM probe session, and include measurement results, node identifiers, probe session IDs, path signatures, and probe packet sequence numbers. The collected context fragments are then deduplicated and sorted, and the multiple performance measurement results are concatenated to form a complete performance profile corresponding to the measurement path. This invention enables accurate fault location and performance trend analysis, significantly improving operational efficiency.
