Traffic engineering and an economical provisioning of bandwidth is crucial for network providers in times of high competition in broadband access networks. We investigate the efficiency of caching as an option to shorten end-to-end paths and delays while at the same time reducing traffic loads. The portion of HTTP based distribution of cacheable content on the Internet is increasing in recent time...
Nowadays, streaming media and web pages have occupied the most bandwidth on the Internet. And it's important to remain the scalability, performance, fairness and resources management potential while providing the Web Service. In this paper, we have proposed a new Web Service Structure of Combining P2P and CDN Technologies. By building a P2P Content Distribution Network (CDN), peers collaborate to...
Traditional client/server architecture has difficulty in coping with the significant growth of user demands due to the continuing growth of video quality and ease of producing video content. Consequently, peer-to-peer (P2P) architecture has become the most feasible solution for providing video content. In order to provide high quality video, piece scheduling, peer selection, failure recovery and a...
As one of the most popular applications in China, Xunlei's excellent performance attracts us to pay more attentions to its system mechanism. The issue of bandwidth theft in Xunlei is one of our focuses. Although its proprietary nature and its use of data encryption hinder our studies of Xunlei to some extent, we analyze and evaluate behaviors of bandwidth theft in Xunlei based on our measurements...
Web-content publishing is a service that is mainly provided by traditional client-server architecture. However, traditional approach requires much computer and network resources and therefore is relatively expensive. There are methods to publish web-content directly from users own computers. But in these approaches users have to keep their computers switched on continuously to publish for 24 hours...
Due to the overload problem of the server, the Web server has become the bottleneck to implement the P2P QoS to some extent. It has become a big problem that how to implement the QoS control in the Web system. We describe a QoS control for Web system based on dynamic monitoring and parameters regulating. It enables web site operators to optimize the usage of their Web sites by prioritizing among requests...
Blog services become popular in recently years. Web users can post their articles through the services. On the other hand, the users do not have full control of the articles after posted while the services are built with client/server model. Therefore, we propose to use peer-to-peer (P2P) technology to establish blog services. However, the anonymous feature disables the P2P technology to conduct user...
