Currently, the network traffic control systems are mainly composed of the Internet core and
wired/wireless heterogeneous backbone networks. Recently, these packet-switched …

The area of Internet traffic measurement has advanced enormously over the last couple of
years. This was mostly due to the increase in network access speeds, due to the …

Network management requires accurate estimates of metrics for traffic engineering (eg,
heavy hitters), anomaly detection (eg, entropy of source addresses), and security (eg, DDoS …

NetFlow has been a widely used monitoring tool with a variety of applications. NetFlow
maintains an active working set of flows in a hash table that supports flow insertion, collision …

Most network management tasks in software-defined networks (SDN) involve two stages:
measurement and control. While many efforts have been focused on network control APIs for …

An emerging trend in network security consists in the adoption of programmable switches for
performing various security tasks in large-scale, high-speed networks. However, since …

Abstract Methods for Approximate Query Processing (AQP) are essential for dealing with
massive data. They are often the only means of providing interactive response times when …

We explore the nature of traffic in data centers, designed to support the mining of massive
data sets. We instrument the servers to collect socket-level logs, with negligible performance …

Network traffic arises from the superposition of Origin-Destination (OD) flows. Hence, a
thorough understanding of OD flows is essential for modeling network traffic, and for …

Network operators need to determine the composition of the traffic mix on links when looking
for dominant applications, users, or estimating traffic matrices. Cisco's NetFlow has evolved …
