The Internet suffers from well-known performance, reliability, and security problems. However, proposed improvements have seen little adoption due to the difficulties of Internet-wide deployment. We observe that, instead of trying to solve these ...

The goal of our work is to characterize the current state of Cuba's access to the wider Internet. This work is motivated by recent improvements in connectivity to the island and the growing commercial interest following the ease of restrictions on ...

Content delivery networks must balance a number of trade-offs when deciding how to direct a client to a CDN server. Whereas DNS-based redirection requires a complex global traffic manager, anycast depends on BGP to direct a client to a CDN front-end. ...

We present initial measurements to determine if ECN is usable with UDP traffic in the public Internet. This is interesting because ECN is part of current IETF proposals for congestion control of UDP-based interactive multimedia, and due to the ...

Energy consumption due to network traffic on mobile devices continues to be a significant concern. We examine a range of excessive energy consumption problems caused by background network traffic through a two-year user study, and also validate these ...

Models of Internet routing are critical for studies of Internet security, reliability and evolution, which often rely on simulations of the Internet's routing system. Accurate models are difficult to build and suffer from a dearth of ground truth data, ...

Knowing the physical location of a mobile device is crucial for a number of context-aware applications. This information is usually obtained using the Global Positioning System (GPS), or by calculating the position based on proximity of WiFi access ...

Public measurement platforms composed of low-end hardware devices such as RIPE Atlas have gained significant traction in the research community. Such platforms are indeed particularly interesting as they provide Internet-wide measurement capabilities ...

WiFi offloading has emerged as a key component of cellular operator strategy to meet the rich data needs of modern mobile devices. Hence, mobile devices tend to aggressively seek out WiFi in order to provide improved user Quality of Experience (QoE) and ...

As the cloud computing market continues to grow, the cloud platform is becoming an attractive target for attackers to disrupt services and steal data, and to compromise resources to launch attacks. In this paper, using three months of NetFlow data in ...

Network-wide activity is when one computer (the originator) touches many others (the targets). Motives for activity may be benign (mailing lists, CDNs, and research scanning), malicious (spammers and scanners for security vulnerabilities), or perhaps ...

Content and services which are offered for free on the Internet are primarily monetized through online advertisement. This business model relies on the implicit agreement between content providers and users where viewing ads is the price for the "free" ...

Active probing techniques, such as ping, have been used to detect outages. When a previously responsive end host fails to respond to a probe, studies sometimes attempt to confirm the outage by retrying the ping or attempt to identify the location of the ...

For more than a decade, unsolicited traffic sent to unused regions of the address space has provided valuable insight into malicious Internet activities. In this paper, we explore the utility of this traffic, known as Internet Background Radiation (IBR),...

Tor is a peer-to-peer overlay routing network that achieves unlinkable communication between source and destination.Unlike traditional mix-nets, Tor seeks to balance anonymity and performance, particularly with respect to providing low-latency ...

The advent of network functions virtualization (NFV) means that data planes are no longer simply composed of routers and switches. Instead they are very complex and involve a variety of sophisticated packet processing elements that reside on the OSes ...

We analyze the evolution of smartphone usage from a dataset obtained from three, 15-day-long, user-side, measurements with over 1500 recruited smartphone users in the Greater Tokyo area from 2013 to 2015. This dataset shows users across a diverse range ...

The com, net, and org TLDs contain roughly 150 million registered domains, and domain registrants often have a difficult time finding a desirable and available name. In 2013, ICANN began delegation of a new wave of TLDs into the Domain Name System with ...

The SMTP protocol is responsible for carrying some of users' most intimate communication, but like other Internet protocols, authentication and confidentiality were added only as an afterthought. In this work, we present the first report on global ...

WHOIS is a long-established protocol for querying information about the 280M+ registered domain names on the Internet. Unfortunately, while such records are accessible in a ``human-readable'' format, they do not follow any consistent schema and thus are ...
