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 …

A system of techniques is presented for optimizing open shortest path first (OSPF) or
intermediate system-intermediate system (IS-IS) weights for intradomain routing in a …

Networks are expected to provide reliable performance under a wide range of operating
conditions, but existing traffic engineering (TE) solutions optimize for performance or …

Destination-based forwarding in traditional IP routers has not been able to take full
advantage of multiple paths that frequently exist in Internet service provider networks. As a …

Current intra-domain Traffic Engineering (TE) relies on offline methods, which use long term
average traffic demands. It cannot react to realtime traffic changes caused by BGP reroutes …

Intra-domain traffic engineering can significantly enhance the performance of large IP
backbone networks. Two important components of traffic engineering are understanding the …

Abstract Open Shortest Path First (OSPF) is one of the most commonly used intra-domain
internet routing protocol. Traffic flow is routed along shortest paths, splitting flow evenly at …

This paper settles an open question with a positive answer: Optimal traffic engineering (or
optimal multicommodity flow) can be realized using just link-state routing protocols with hop …

We present a new algorithm, A* Prune, to list (in order of increasing length) the first K
multiple-constrained-shortest-path (KMCSP) between a given pair of nodes in a digraph in …

TCP's burstiness is usually regarded as harmful, or at best, inconvenient. This paper adopts
a new perspective and examines whether TCP's burstiness is useful for certain applications …
