Biography
Hiroaki Nishi received his B.E., M.E., and Ph.D. degrees from Keio University, Japan, in 1994, 1996, and 1999, respectively. Since 2007, he has been an Associate Professor at Keio University, and since 2010, a Visiting Associate Professor of National Institute of Informatics (NII), Japan. The main theme of his current research is in building of the total network system including development of hardware and software architecture. He places great importance on considering what is required for the highly networked information society in the future. He is investigating the Next generation IP router architecture and Effective Network Systems for Electricity Transaction and Energy Saving in Smart Energy field.

Delivery of data-enriched applications has become a top priority on the Internet, and Internet users are demanding faster and higher-quality services. Cater such requirements, Content Delivery Networks (CDNs) were introduced. However, the growth rate of information on the Internet requires infrastructural modifications to keep the consistency while maintaining quality of the Internet services. To this end, the Service-oriented Router is introduced to provide content based services by shifting the current Internet infrastructure to information-based open innovation platform. In this study, initially we provide implementation notes of a software-designed SoR. Then we propose a new method of CDN Request Redirection (RR) (SoR-based RR), which is designed to redirect packets based on the content of packets and the status of content servers using an SoR as an edge router of a CDN. Furthermore, we present the design and implementation of a prototype to realize the SoR-based RR in a testing network. By analyzing the result of the prototype implementation, we show that the SoR-based RR can enhance the both client experience and faster adaptations to the server changes in CDN environments.
