Monitoring, Analyzing and Characterizing Lookup Traffic in a Large-Scale DHT
Lookup is crucial to locate peers and resources in structured P2P networks. In this paper, the authors measure and analyze the traffic characteristics of lookup in Kad, which is a widely used DHT network. Some previous works studied the user behaviors of Kad, yet they believe that investigating its traffic characteristics will also be beneficial, as it gives feedbacks to fine-tune the system parameters, helps to uncover the abnormalities or misuses, and provides solid ground for synthesizing P2P traffic to evaluate future designs. To track the lookup requests more efficiently and from more peers in Kad, they develop an active traffic monitor, named Rememj.
