Recent years have witnessed a thriving development of web service all over the world.Almost every imaginable service in our everyday life becomes available online.With the increasing number of web services, a lot of works has been done with regard to the issue of web service discovery.The prevailing service discovery architectures are centralized architecture and distributed architecture.Since the former is considered to be weak at robustness and scalability, a significant research attention is focused on the latter one.However, most of the existing works do not cover the modeling of traffic.To address this problem, we in this paper present a Chord-based traffic model for web service discovery in distributed environment.The proposed model analyzes the node behavior through the operation of five queues.The traffic of a node is regulated by a traffic management module.Different traffic management policies are analyzed for the purpose of improving the availability and latency of service discovery in a Chord network.In order to evaluate our model, we conduct extensive experiments and make an analysis of the simulation results.
