Evaluation of the Integration Effect of Content Location and Request Routing in Content Distribution NetworksEvaluation of the Integration Effect of Content Location and Request Routing in Content Distribution NetworksengDC-DPOhttp://id.nii.ac.jp/1001/00009737/Journal Articlehttps://ipsj.ixsq.nii.ac.jp/ej/?action=repository_action_common_download&item_id=9737&item_no=1&attribute_id=1&file_no=1Copyright (c) 2008 by the Information Processing Society of Japanネットワークサービス基礎Fuculty of Systems Engineering Wakayama UniversityFaculty of Engineering Science Kansai UniversityHirokazu, MiuraMiki, YamamotoRecently the content distribution networks (CDNs) have been highlighted as the new network paradigm which can improve latency for Web access. In CDNs the content location strategy and request routing techniques are important technical issues. Both of them should be used in an integrated manner in general but CDN performance applying both these technologies has not been evaluated in detail. In this paper we investigate the effect of integration of these techniques. For request routing we focus on a request routing technique applied active network technology Active Anycast which improves both network delay and server processing delay. For content distribution technology we propose a new strategy Popularity-Probability whose aim corresponds with that of Active Anycast. Performance evaluation results show that integration of Active Anycast and Popularity-Probability can hold stable delay characteristics.Recently the content distribution networks (CDNs) have been highlighted as the new network paradigm which can improve latency for Web access.
