Internet backbone networks are under constant flux, struggling to keep up with increasing
demand. The pace of technology change often outstrips the deployment of associated fault …

Due to the dramatic increase in competition over the last few years, it has become more and
more important for Internet Service Providers (ISPs) to run an efficient business and offer an …

Entropy has recently gained considerable significance as an important metric for network
measurement. Previous research has shown its utility in clustering traffic and detecting traffic …

We consider the realization of traffic-oblivious routing in IP-over-optical networks where
routers are interconnected over a switched optical backbone. The traffic-oblivious routing we …

Intradomain routing protocols, such as IS-IS or OSPF, associate a weight (or cost) with each
link to compute traffic routes. Proposed methods for selecting link weights largely ignore two …

Ambient Networks defines a new kind of network architecture, which embeds support for co
operation and competition between diverse network types within a common control layer …

Point-to-point delay is an important network performance measure as it captures service
degradations caused by various events. We study how to measure and report delay in a …

In this paper we propose a new approach for dealing with the ill-posed nature of traffic matrix
estimation. We present three solution enhancers: an algorithm for deliberately changing link …

We study the problem of integrated topology control and routing in Free Space Optical (FSO)
mesh backbone networks. FSO links are high-bandwidth, low interference links that can be …

We study the problem of identifiability of distributions of flows on a graph from aggregate
measurements collected on its edges. This is a canonical example of a statistical inverse …
