Traffic optimizations (TO, eg flow scheduling, load balancing) in datacenters are difficult
online decision-making problems. Previously, they are done with heuristics relying on …

Network performance monitoring today is restricted by existing switch support for
measurement, forcing operators to rely heavily on endpoints with poor visibility into the …

Network performance anomalies (NPAs), eg long-tailed latency, bandwidth decline, etc., are
increasingly crucial to cloud providers as applications are getting more sensitive to …

Network Traffic Monitoring and Analysis (NTMA) represents a key component for network
management, especially to guarantee the correct operation of large-scale networks such as …

Data center network (DCN) is the backbone of many emerging applications from smart

The availability of data center services is jeopardized by various network incidents. One of
the biggest challenges for network incident handling is to accurately localize the failures …

Network failures continue to plague datacenter operators as their symptoms may not have
direct correlation with where or why they occur. We introduce 007, a lightweight, always-on …

Ensuring the reliability and availability of cloud services necessitates efficient root cause
analysis (RCA) for cloud incidents. Traditional RCA methods, which rely on manual …
