Abstract
Traffic measurement plays an important role in many network-management tasks, such as anomaly detection and traffic engineering. However, existing solutions either rely on custom hardware designed for a specific task, or introduce a high overhead for data collection and analysis. Instead, we argue that a practical traffic-measurement solution should run on commodity network elements, support a range of measurement tasks, and provide accurate results with low overhead. Inspired by the capabilities of OpenFlow switches, we explore a measurement framework where switches match packets against a small collection of rules and update traffic counters for the highest-priority match. A separate controller can read the counters and dynamically tune the rules to quickly “drill down” to identify large traffic aggregates. As the first step towards designing measurement algorithms for this framework, we design and evaluate a hierarchical heavy hitters algorithm that identifies large traffic aggregates, while striking a good balance between measurement accuracy and switch overhead.
