A Fast and Compact Invertible Sketch for Network-Wide Heavy Flow Detection
Lu Tang, Qun Huang, Patrick P. C. Lee
Fast detection of heavy flows (e.g., heavy hitters and heavy changers) in massive network traffic is challenging due to the stringent requirements of fast packet processing and lim…
Repair Pipelining for Erasure-Coded Storage: Algorithms and Evaluation
Xiaolu Li, Zuoru Yang, Jinhong Li +4
We propose repair pipelining, a technique that speeds up the repair performance in general erasure-coded storage. By carefully scheduling the repair of failed data in small-size un…
Metaflow: A DAG-Based Network Abstraction for Distributed Applications
Jiawei Fei, Yang Shi, Qun Huang +1
In the past decade, increasingly network scheduling techniques have been proposed to boost the distributed application performance. Flow-level metrics, such as flow completion time…
On the Performance and Convergence of Distributed Stream Processing via Approximate Fault Tolerance
Zhinan Cheng, Qun Huang, Patrick P. C. Lee
Fault tolerance is critical for distributed stream processing systems, yet achieving error-free fault tolerance often incurs substantial performance overhead. We present AF-Stream,…
