Agile Development of Linux Schedulers with Ekiben
Samantha Miller, Anirudh Kumar, Tanay Vakharia +3
Kernel task scheduling is important for application performance, adaptability to new hardware, and complex user requirements. However, developing, testing, and debugging new schedu…
Symbolic Distillation for Learned TCP Congestion Control
S P Sharan, Wenqing Zheng, Kuo-Feng Hsu +3
Recent advances in TCP congestion control (CC) have achieved tremendous success with deep reinforcement learning (RL) approaches, which use feedforward neural networks (NN) to lear…
Templating Shuffles
Qizhen Zhang, Jiacheng Wu, Ang Chen +2
Cloud data centers are evolving fast. At the same time, today's large-scale data analytics applications require non-trivial performance tuning that is often specific to the applica…
MXDAG: A Hybrid Abstraction for Cluster Applications
Weitao Wang, Sushovan Das, Xinyu Crystal Wu +3
Distributed applications, such as database queries and distributed training, consist of both compute and network tasks. DAG-based abstraction primarily targets compute tasks and ha…
Shufflecast: An Optical, Data-rate Agnostic and Low-Power Multicast Architecture for Next-Generation Compute Clusters
Sushovan Das, Afsaneh Rahbar, Xinyu Crystal Wu +4
An optical circuit-switched network core has the potential to overcome the inherent challenges of a conventional electrical packet-switched core of today's compute clusters. As opt…
The Design and Implementation of a Verified File System with End-to-End Data Integrity
Daniel W. Song, Konstantinos Mamouras, Ang Chen +2
Despite significant research and engineering efforts, many of today's important computer systems suffer from bugs. To increase the reliability of software systems, recent work has…
Programmable In-Network Security for Context-aware BYOD Policies
Qiao Kang, Lei Xue, Adam Morrison +3
Bring Your Own Device (BYOD) has become the new norm in enterprise networks, but BYOD security remains a top concern. Context-aware security, which enforces access control based on…
Quantitative Impact Evaluation of an Abstraction Layer for Data Stream Processing Systems
Guenter Hesse, Christoph Matthies, Kelvin Glass +2
With the demand to process ever-growing data volumes, a variety of new data stream processing frameworks have been developed. Moving an implementation from one such system to anoth…
Contra: A Programmable System for Performance-aware Routing
Kuo-Feng Hsu, Ryan Beckett, Ang Chen +3
We present Contra, a system for performance-aware routing that can adapt to traffic changes at hardware speeds. While existing work has developed point solutions for performance-aw…
An Historical Analysis of the SEAndroid Policy Evolution
Bumjin Im, Ang Chen, Dan Wallach
Android adopted SELinux's mandatory access control (MAC) mechanisms in 2013. Since then, billions of Android devices have benefited from mandatory access control security policies.…
STor: Social Network based Anonymous Communication in Tor
Peng Zhou, Xiapu Luo, Ang Chen +1
Anonymity networks hide user identities with the help of relayed anonymity routers. However, the state-of-the-art anonymity networks do not provide an effective trust model. As a r…
