Approximate Networking for Global Access to the Internet for All (GAIA)
Junaid Qadir, Arjuna Sathiaseelan, Liang Wang +1
Decades of experience have shown that there is no single one-size-fits-all solution that can be used to provision Internet globally and that invariably there are tradeoffs in the d…
Galleon: Reshaping the Square Peg of NFV
Jianfeng Wang, Tamás Lévai, Zhuojin Li +3
Software is often used for Network Functions (NFs) -- such as firewalls, NAT, deep packet inspection, and encryption -- that are applied to traffic in the network. The community ha…
Semi-Automated Protocol Disambiguation and Code Generation
Jane Yen, Tamás Lévai, Qinyuan Ye +3
For decades, Internet protocols have been specified using natural language. Given the ambiguity inherent in such text, it is not surprising that protocol implementations have long…
Tactical Patterns for Grassroots Urban Repair
Sarah Cooney, Barath Raghavan
The process of revitalizing cities in the United States suffers from balky and unresponsive processes---de jure egalitarian but de facto controlled and mediated by city officials a…
Pretty Good Phone Privacy
Paul Schmitt, Barath Raghavan
To receive service in today's cellular architecture, phones uniquely identify themselves to towers and thus to operators. This is now a cause of major privacy violations, as operat…
A Pluralist Approach to Democratizing Online Discourse
Jay Chen, Barath Raghavan, Paul Schmitt +1
Online discourse takes place in corporate-controlled spaces thought by users to be public realms. These platforms in name enable free speech but in practice implement varying degre…
Rangzen: Anonymously Getting the Word Out in a Blackout
Adam Lerner, Giulia Fanti, Yahel Ben-David +3
In recent years governments have shown themselves willing to impose blackouts to shut off key communication infrastructure during times of civil strife, and to surveil citizen comm…
SoK: The Ghost Trilemma
Sulagna Mukherjee, Srivatsan Ravi, Paul Schmitt +1
Trolls, bots, and sybils distort online discourse and compromise the security of networked platforms. User identity is central to the vectors of attack and manipulation employed in…
Beyond the Trees: Resilient Multipath for Last-mile WISP Networks
Bilal Saleem, Paul Schmitt, Jay Chen +1
Expanding the reach of the Internet is a topic of widespread interest today. Google and Facebook, among others, have begun investing substantial research efforts toward expanding I…
Recursive SDN for Carrier Networks
James McCauley, Zhi Liu, Aurojit Panda +4
Control planes for global carrier networks should be programmable (so that new functionality can be easily introduced) and scalable (so they can handle the numerical scale and geog…
Migration in the Stencil Pluralist Cloud Architecture
Tai Liu, Zain Tariq, Barath Raghavan +1
A debate in the research community has buzzed in the background for years: should large-scale Internet services be centralized or decentralized? Now-common centralized cloud and we…
Robotic Lime Picking by Considering Leaves as Permeable Obstacles
Heramb Nemlekar, Ziang Liu, Suraj Kothawade +3
The problem of robotic lime picking is challenging; lime plants have dense foliage which makes it difficult for a robotic arm to grasp a lime without coming in contact with leaves.…
Information Batteries: Storing Opportunity Power with Speculative Execution
Jennifer Switzer, Barath Raghavan
Coping with the intermittency of renewables is a fundamental challenge, with load shifting and grid-scale storage as key responses. We propose Information Batteries (IB), in which…
