Various promising distributing computing paradigms such as Grids, P2P and Clouds have emerged over Internet. How to build the trust relationship among principals in such an open computing environment has become an important issue. Automated trust negotiation (ATN) approach aims to gradually build trust relationship between strangers through the interactively disclosing of credentials and security...
The increasingly popular online hosting systems are designed to provide versatile and convenient platforms for content hosting and sharing. To guarantee adequate levels of service quality while conserving prohibitive server costs, such systems are often designed to integrate peer bandwidth contributions with strategic server resource provisioning in a complementary and transparent manner. This paper...
Online storage systems that provide versatile and convenient platforms for content distribution have attracted significant attention over the Internet. To guarantee adequate levels of service quality and to minimize server cost, such systems typically deploy dedicated servers while effectively utilizing peer bandwidth in a complementary fashion. It is essential to understand the role of servers and...
The peer-to-peer (P2P) live video streaming system has been demonstrated to have great potential in the public Internet; the large-scale deployment of such systems, however, critically relies on how effective they can deal with the high dynamics encountered, in particular during flash crowd. The rationale behind is that the scaling in P2P live video streaming systems is heavily determined by the timing...
Peer-to-peer (P2P) live video streaming systems have recently received significant attention, with commercial deployment gaining increased popularity in the Internet. It is evident from our experiences with real-world systems that, it is not uncommon to have hundreds of thousands of users trying to join a program in the first few minutes of a live broadcast. This phenomenon, unique in live streaming...
Summary form only given. Online storage and content distribution systems within the "cloud" of the Internet have provided a wide variety of services ranging from file sharing, software downloads, to stored or live video streaming, to a large community. With the increasing popularity of such systems, however, server and bandwidth costs have become prohibitively expensive, as files are hosted...
Pull-based mesh streaming protocols have recently received much research attention, with successful commercial systems showing their viability in the Internet. Despite the remarkable popularity in real-world systems, the fundamental properties and limitations of pull-based protocols are not yet well understood from a theoretical perspective, as there exists no prior work that studies the performance...
It has been widely acknowledged that online storage systems within the "cloud" of the Internet provide services of a substantial value to end users who wish to share files of any sizes within a group. Such online storage services are typically provided by dedicated servers, either in content distribution networks (CDNs) or large data centers. Server bandwidth costs, however, are prohibitive...
Peer-to-peer (P2P) based live video streaming system has emerged as a promising solution for the Internet video streaming applications, partly evident from commercial deployment of several large-scale P2P streaming systems. The key is to leverage the resources available at end users, which offers great potential to scale in the Internet. Flash crowd poses a unique challenge for live streaming systems,...
The peer-to-peer (P2P) based video streaming has emerged as a promising solution for Internet video distribution. Leveraging the resource available at end users, this approach poses great potential to scale in the Internet. We have now seen the commercial P2P streaming systems that are orders of magnitude larger than the earlier academic systems. We believe understanding its basic principles and limitations...
