Network topology design at 27,000 km/hour
TLDR
We exploit repetitive patterns in the network topology to avoid expensive link changes over time, while still providing near-minimal latencies at nearly 2× the throughput of standard past methods. Expand
Gearing up for the 21st century space race
TLDR
A new space race is imminent, with several industry players working towards satellite-based Internet connectivity. Expand
Stepping Stone Detection for Tracing Attack Sources in Software-Defined Networks
TLDR
Stepping stones are compromised hosts in a network which can be used by hackers and other malicious attackers to hide the origin of connections. Expand
In-orbit Computing: An Outlandish thought Experiment?
TLDR
We examine, qualitatively and quantitatively, the opportunities and challenges of such in-orbit computing. Expand
A Cloud-based Content Gathering Network
TLDR
We explore a complementary model of speeding up Web page delivery - a content gathering network (CGN), whereby users establish their own geo-distributed presence, and use these points of presence to proxy content for them. Expand
cISP: A Speed-of-Light Internet Service Provider
TLDR
We explore the design of cost-effective wide-area networks that move data over paths very close to great-circle paths at the speed of light, over medium and long distances. Expand
Watch Your Step! Detecting Stepping Stones in Programmable Networks
TLDR
In this paper, we explore how today's programmable networks could be retrofitted with effective stepping stone detection mechanisms to correlate flows. Expand
Exploring the "Internet from space" with Hypatia
TLDR
We present Hypatia, a framework for simulating and visualizing the network behavior of these constellations by incorporating their unique characteristics, such as high-velocity orbital motion. Expand
"Internet from Space" without Inter-satellite Links
TLDR
We show that inter-satellite links substantially reduce the temporal variations in latency, add greater resilience to weather, and could yield more than 3x the throughput achieved without such links. Expand
Untangling Header Bidding Lore
TLDR
We use real end-user measurements from 393,400 HB auctions to (a) quantify the ad revenue from HB auctions, (b) estimate latency overheads when integrating with ad exchanges and discuss their implications for ad revenue, and (c) break down the time spent in soliciting bids from ad exchanges into various factors and highlight areas for improvement.
