Network monitoring is essential for network management and optimization. In modern data
centers, fluctuations in flow rates and network congestion events (eg, microbursts) typically …

Approximate membership query (AMQ) data structures can approximately determine
whether an element is in the set with high efficiency. They are widely used in distributed …

Recent network telemetry solutions typically target programmable switches to achieve high
performance and in-network visibility. They partition the packet stream into windows and …

Per-flow size measurement is key to many streaming applications and management
systems, particularly in high-speed networks. Performing such measurement on the data …

Network telemetry systems have become hybrid combinations of state-of-the-art stream
processors and modern programmable data-plane devices. However, the existing designs …

Network operators require real-time traffic monitoring insights to provide high performance
