Content/Location Mapping with Cache-Location Resolution for In-network Guidance

Abstract—In recent years, the popularity of large contents such as high-definition video and music is increasing content server loads and the amount of traffic on the backbone networks. To tackle this problem, we propose an Mapping Server with Cache-location Resolution (MSCR), which resolves prospective cache locations (PCLs) close to the requesting user as well as content server location. Sending a query to a nearby PCL enables the user to obtain the content more efficiently. Our simulation shows that MSCR can reduce content server loads and the amount of traffic on core networks.
