LEISURE: A Framework for Load-Balanced Network-Wide Traffic Measurement

Abstract— LEISURE: A Framework for Load-Balanced Network-Wide Traffic Measurement. Network-wide traffic measurement is of interest to network operators to uncover global network behavior for the management tasks of traffic accounting, debugging or troubleshooting, security, and traffic engineering. Increasingly, sophisticated network measurement tasks such as anomaly detection and security forensic analysis are requiring in-depth fine-grained flow-level measurements. However, performing in-depth per-flow measurements e.g.,< Final Year Projects 2016 > detailed payload analysis is often an expensive process. Given the fast-changing Internet traffic landscape and large traffic volume, a single monitor is not capable of accomplishing the measurement tasks for all applications of interest due to its resource constraint. Moreover, uncovering global network behavior requires network wide traffic measurements at multiple monitors across the network since traffic measured at any single monitor.
