Title:Network Measurement at Scale
Date: November 02, 2018 (Friday)
Time: 4:00 pm - 5:00 pm
Venue: Room 121, 1/F, Ho Sin-hang Engineering Building, The Chinese University of Hong Kong, Shatin, N.T.
Speaker: Prof. Patrick P. C. Lee
Associate Professor

The Chinese University of Hong Kong

ABSTRACT:

Operators heavily rely on network measurement to characterize traffic statistics for effective network management.  However, network measurement remains a missing piece in today's enterprise and data center networks. On one hand, achieving timely and accurate network measurement is necessary; on the other hand, measurement tasks unavoidably add performance overhead to the packet processing pipeline. In this talk, I will present two novel sketch-based designs that enable space-efficient, high-performance, accurate, and practical network measurement at large scale.  I will present SketchVisor, a framework that maintains high performance of general sketch-based measurement tasks by opportunistically offloading measurement to a fast path. Then I will present SketchLearn, an automated self-learning sketch design that requires limited configuration burdens from operators while maintaining high performance and high accuracy in network measurement.
