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 …

Many computer vision tasks can be formulated as labeling problems. The desired solution is
often a spatially smooth labeling where label transitions are aligned with color edges of the …

As peer-to-peer (P2P) emerges as a major paradigm for scalable network application
design, it also exposes significant new challenges in achieving efficient and fair utilization of …

Geo-replicated services need an effective way to direct client requests to a particular
location, based on performance, load, and cost. This paper presents DONAR, a distributed …

Inter-domain bandwidth costs comprise a significant amount of the operating expenditure of
cloud providers. Traffic engineering systems at the cloud edge must strike a fine balance …

A large amount of popular content is transferred repeatedly across network links in the
Internet. In recent years, protocol-independent redundancy elimination, which can remove …

Many cloud services are running on geographically distributed datacenters for better
reliability and performance. We consider the emerging problem of joint request mapping and …

The ability to locate network bottlenecks along end-to-end paths on the Internet is of great
interest to both network operators and researchers. For example, knowing where bottleneck …

In today's Internet, users can choose their local Internet service providers (ISPs), but once
their packets have entered the network, they have little control over the overall routes their …

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 …
