Building a Better NetFlow (2004)
Cristian Estan, Ken Keys, David Moore, George Varghese
Network operators need to determine the composition of the tra#c mix on links when looking for dominant applications, users, or estimating tra#c matrices. Cisco's NetFlow has evolved into a solution...

The Measurement Manifesto (2003)
George Varghese, Cristian Estan
Useful measurement data is badly needed to help monitor and control large networks. Current approaches to solving measurement problems often assume minimal support from routers and protocols (e.g.,...
Bitmap Algorithms for Counting Active Flows on High (2003)
Cristian Estan, George Varghese, Mike Fisk
This paper presents a family of bitmap algorithms that address the problem of counting the number of distinct header patterns (flows) seen on a high speed link. Such counting can be used to detect...

Automatically Inferring Patterns of Resource Consumption in Network Traffic (2003)
Cristian Estan, Stefan Savage, George Varghese
The Internet service model emphasizes flexibility -- any node can send any type of tra#c at any time. While this design has allowed new applications and usage models to flourish, it also makes the...
Automated Measurement of High Volume Traffic (2003)
Cristian Estan, Stefan Savage, George Varghese
Traffic measurement often focuses on measuring traffic at various granularities. Our paper considers an approach that generalizes previous solutions: we define a traffic cluster to consist of all...
New Directions in Traffic Measurement and Accounting (2003)
Cristian Estan, George Varghese
Accurate network traffic measurement is required for accounting, bandwidth provisioning and detecting DoS attacks. These applications see the traffic as a collection of flows they need to measure. As...
Automated Measurement of High Volume Traffic (2002)

Traffic measurement often focuses on measuring traffic at various granularities. Our paper considers an approach that generalizes previous solutions: we define a traffic cluster to consist of all...
New Directions in Traffic Measurement and Accounting (2001)
Cristian Estan, George Varghese
Accurate network traffic measurement is required for accounting, bandwidth provisioning, and detecting DOS attacks. However, keeping a counter to measure the traffic sent by each of a million...
