ShortMAC: Efficient Data-Plane Fault Localization

Free registration required

Executive Summary

The rising demand for high-quality online services requires reliable packet delivery at the network layer. Data-plane fault localization is recognized as a promising means to this end, since it enables a source node to localize faulty links, find a fault-free path, and enforce contractual obligations among network nodes. Existing fault localization protocols cannot achieve a practical tradeoff between security and efficiency and they require unacceptably long detection delays, and require monitored flows to be impractically long-lived.
