Content delivery networks (CDNs) have gained immense popularity over the years. Replica
server placement is a key design issue in CDNs. It entails placing replica servers at …

Increased popularity and wealth-creation potential of conventional mobile phones, smart
phones and tablet computers resulted in the unprecedented penetration of wired and …

In a packet network, the terms bandwidth and throughput often characterize the amount of
data that the network can transfer per unit of time. Bandwidth estimation is of interest to users …

Available bandwidth estimation is useful for route selection in overlay networks, QoS
verification, and traffic engineering. Recent years have seen a surge in interest in available …

In this paper, we present the design, implementation, and evaluation of iPlane, a scalable
service providing accurate predictions of Internet path performance for emerging overlay …

Distributed deep neural network (DDNN) training constitutes an increasingly important
workload that frequently runs in the cloud. Larger DNN models and faster compute engines …

Next-generation wireless systems (NGWS) integrate different wireless networks, each of
which is optimized for some specific services and coverage area to provide ubiquitous …

Cloud computing has found broad acceptance in both industry and research, with public
cloud offerings now often used in conjunction with privately owned infrastructure. Technical …

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 …

We present a new capacity estimation technique, called CapProbe. CapProbe combines
delay as well as dispersion measurements of packet pairs to filter out samples distorted by …
