Quality measuring system for network provisioning and customer service in content delivery

In Japan, medium- to high-speed access networks using technologies such as ADSL have recently been expanding rapidly. We propose a quality management system enabling efficient, accurate measurement of streaming video quality to meet the requirements of network provisioning and customer service. Streaming video is delivered through a content delivery network (CDN) consisting of a content server, network, and customers' personal computers (client PC). In the digital content delivery business, it is thus necessary to manage the overall quality for all these elements.
