Anomalies are unusual and significant changes in a network's traffic levels, which can often
span multiple links. Diagnosing anomalies is critical for both network operators and end …

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 …

Knowing the distribution of the sizes of traffic flows passing through a network link helps a
network operator to characterize network resource usage, infer traffic demands, detect traffic …

This paper considers the problem of estimating the point-to-point traffic matrix in an
operational IP backbone. Contrary to previous studies, that have used a partial traffic matrix …

In this paper we investigate a new idea for traffic matrix estimation that makes the basic
problem less under-constrained, by deliberately changing the routing to obtain additional …

Designing a backbone network is hard. On one hand, users expect the network to have very
high availability, little or no congestion, and hence little or no queueing delay. On the other …

The traffic matrix of a telecommunications network is an essential input for any kind of
network design and capacity planning decision. In this paper we address a debate …

If efficient network analysis tools were available, it could become possible to detect the
attacks, anomalies and to appropriately take action to contain the attacks. In this paper, we …

Link and node failures in IP networks pose a challenge for network control algorithms.
Routing restoration, which computes new routes that avoid failed links, involves fundamental …

Hot-potato routing is a mechanism employed when there are multiple (equally good)
interdomain routes available for a given destination. In this scenario, the Border Gateway …
