Software switches are emerging as a vital measurement vantage point in many networked
systems. Sketching algorithms or sketches, provide high-fidelity approximate measurements …

Sketches have successfully provided accurate and fine-grained measurements (eg, flow
size and heavy hitters) which are imperative for network management. In particular, Count …

Managing data center networks with low loss requires understanding traffic dynamics at
short (millisecond) time-scales, especially the burstiness of traffic, and to what extent bursts …

Microbursts can degrade application performance in datacenters by causing increased
latency, jitter and packet loss. The detection of microbursts and identification of the …

In recent years, as a result of the proliferation of non-elastic services and the adoption of
novel paradigms, monitoring networks with high level of detail is becoming crucial to …

Modern database systems are growing increasingly distributed and struggle to reduce query
completion time with a large volume of data. In this paper, we leverage programmable …

We design and evaluate SwiSh, a distributed shared state management layer for data-plane
P4 programs. SwiSh enables running scalable stateful distributed network functions on …

Micro-burst traffic is not uncommon in data centers. It can cause packet drop**, which
results in serious performance degradation (eg, Incast problem). However, current solutions …

In-Band Network Telemetry (INT) is a novel framework for collecting telemetry items and
switch internal state information from the data plane at line rate. With the support of …

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