Content centric network (CCN) has been regarded as one of the most promising architecture solution for the future Internet, which has great advantages in support of content delivery services, such as Video-on-demand (VoD) application. Although there are some existing models proposed for the cache performance in CCN router, few of them consider the case of video request traffic. In this paper, we focus...
In the last decades, along with the continuously evolving of the Internet Protocol-based network, numerous Internet programs that have played critical roles in the current technological era are being developed inclusive of interactive applications. Nevertheless, the transmission performance and user experience of these instant services that require high bandwidth or low latency may suffer when serious...
The hybrid architecture of content distribution network (CDN) and peer to peer (P2P) is promising in providing online streaming media services. In this paper, we conducted a comprehensive measurement study on Kankan, one of the leading VoD streaming service providers in China that is based on a hybrid CDN-P2P architecture. Our measurements are multi-fold, as follows. 1) Kankan adopts a loosely-coupled...
An accurate understanding on the content popularity distribution of media objects in streaming applications is required when designing efficient caching algorithms for the streaming media. However, there is no empirical model to describe this distribution. Our investigation shows that the content popularity of a hot streaming media file exhibits a Zipf-like distribution under K-transformation, after...
