Methods for Duplicate Measurement Avoidance and Sketch Placement in Distributed Sketching
Woohyeon Kim, Noriaki Kamiyama (Ritsumeikan Univ) NS2025-278
Abstract (in Japanese) (See Japanese page) 
(in English) As the development of content continues to expand network scale and traffic volume, there is an increasing demand for efficient and highly accurate traffic measurement under limited memory resources. Sketch algorithms have recently attracted significant attention as a low-cost approach that summarizes flow information into compact data structures, enabling approximate traffic measurement. However, in distributed environments, challenges such as redundant measurements and the optimization of sketch node placement arise. In this paper, we propose a sketch node placement scheme based on betweenness centrality, along with a method to avoid redundant measurements, and evaluate their effectiveness through simulations.
