Managing and securing networks requires collecting and analyzing network traffic data in
real time. Existing telemetry systems do not allow operators to express the range of queries …

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 measurement is challenged to fulfill stringent resource requirements in the face of
massive network traffic. While approximate measurement can trade accuracy for resource …

In recent years, Distributed Denial-of-Service (DDoS) attacks have escalated both in
frequency and traffic volume, with outbreaks reaching rates up to the order of terabits per …

In the context of the emergent Software-Defined Networking (SDN) paradigm, the attention is
mostly directed to the evolution of control protocols and networking functionalities. However …

Fine-grained traffic flow records enable many powerful applications, especially in
combination with telemetry systems that supports high coverage, ie, of every link and at all …

Distributed Denial-of-Service (DDoS) attacks have been steadily escalating in frequency,
scale, and disruptiveness-with outbreaks reaching multiple terabits per second and …

Linear sketches have been widely adopted to process fast data streams, and they can be
used to accurately answer frequency estimation, approximate top K items, and summarize …

Monitoring and debugging large-scale networks remains a challenging problem. Existing
solutions operate at one of the two extremes—systems running at end-hosts (more …

Network measurement is important to data center operators. Most existing efforts focus on
developing new implementation schemes for measurement tasks. Little attention is paid to …
