XShot: Light-weight Link Failure Localization using Crossed Probing Cycles in SDN
Hongyun Gao, Laiping Zhao, Huanbin Wang, Zhao Tian, Lihai Nie, Keqiu Li · 2020
Accurate and quick failure localization is critical for automatic network troubleshooting. While it is particularly difficult to solve the problem in the traditional network due to the uncertain routing, Software Defined Networking (SDN) enables the deterministic routing for packet transmission through the traffic engineering algorithm in the centralized controller.
