Traffic engineering is an important mechanism for Internet network providers seeking to
optimize network performance and traffic delivery. Routing optimization plays a key role in …

The routers in an Autonomous System (AS) must distribute the information they learn about
how to reach external destinations. Unfortunately, today's internal Border Gateway Protocol …

Detecting and understanding anomalies in IP networks is an open and ill-defined problem.
Toward this end, we have recently proposed the subspace method for anomaly diagnosis. In …

The complexity of network management is widely recognized as one of the biggest
challenges facing the Internet today. Point solutions for individual problems further increase …

Over the past decade, the complexity of the Internet's routing infrastructure has increased
dramatically. This complexity and the problems it causes stem not just from various new …

Traffic engineering plays a critical role in determining the performance and reliability of a
network. A major challenge in traffic engineering is how to cope with dynamic and …

Prior work on centralized Routing Control Platform (RCP) has shown many benefits in
flexible routing, enhanced security, and ISP connectivity management tasks. In this paper …

Current distributed routing paradigms (such as link-state, distance-vector, and path-vector)
involve a convergence process consisting of an iterative exploration of intermediate routes …

Formally, the Internet inter-domain routing system is a collection of networks, their policies,
peering relationships and organizational affiliations, and the addresses they advertize. It …

Link failures are part of the day-to-day operation of a network due to many causes such as
maintenance, faulty interfaces, and accidental fiber cuts. Commonly deployed link state …
