A Distributed Protocol to Serve Dynamic Groups for Peer-to-Peer Streaming
Found in: IEEE Transactions on Parallel and Distributed Systems
By Xing Jin, S.-H. Gary Chan, Wan-Ching Wong, Ali C. Begen
Issue Date:February 2010
pp. 216-228
Peer-to-peer (P2P) streaming has been widely deployed over the Internet. A streaming system usually has multiple channels, and peers may form multiple groups for content distribution. In this paper, we propose a distributed overlay framework (called SMesh)...
Scalable and Efficient End-to-End Network Topology Inference
Found in: IEEE Transactions on Parallel and Distributed Systems
By Xing Jin, Wanqing Tu, S.-H. Gary Chan
Issue Date:June 2008
pp. 837-850
We consider using tools like traceroute to infer the underlay topology among a group of hosts. Traditional Max-Delta inference relies on a central server and is not scalable. In this paper, we investigate a distributed inference scheme to support scalable ...
Deployment Issues in Scalable Island Multicast for Peer-to-Peer Streaming
Found in: IEEE Multimedia
By Xing Jin, Ho-Shing Tang, S.-H. Gary Chan, Kan-Leung Cheng
Issue Date:January 2009
pp. 72-80
<p>The Scalable Island Multicast protocol integrates Internet Protocol multicast and overlay delivery for media streaming.</p>
Scalable Real-Time Monitoring for Distributed Applications
Found in: IEEE Transactions on Parallel and Distributed Systems
By C.-H. Philip Yuen,S.-H. Gary Chan
Issue Date:December 2012
pp. 2330-2337
In order to assess service quality of a networked application (such as a streaming session), distributed monitoring servers need to continuously collect application-specific performance metrics in real time. Much of the previous work to address this is to ...
Modeling and Dimensioning Hierarchical Storage Systems for Low-Delay Video Services
Found in: IEEE Transactions on Computers
By S.-H. Gary Chan, Fouad A. Tobagi
Issue Date:July 2003
pp. 907-919
<p><b>Abstract</b>—In order to cost-effectively accommodate a large number of titles in a video system, a hierarchical storage system can be used. In this system, not-so-popular video files are stored in a tertiary level such as a disk/ta...
Loss Recovery in Application-Layer Multicast
Found in: IEEE Multimedia
By Xing Jin, W.-P. Ken Yiu, S.-H. Gary Chan
Issue Date:January 2008
pp. 18-27
Application-layer multicast, sometimes called overlay multicast, can help circumvent the limitations in IP multicast and unicast.
Challenges and Approaches in Large-Scale P2P Media Streaming
Found in: IEEE Multimedia
By W.-P. Ken Yiu, Xing Jin, S.-H. Gary Chan
Issue Date:April 2007
pp. 50-59
Large-scale multimedia streaming over the Internet requires an enormous amount of server and network resources. Traditional client?server approaches allocate a dedicated stream from the server for each client request, which is expensive and doesn't scale w...
Dissecting User Behaviors for a Simultaneous Live and VoD IPTV System
Found in: ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP)
By Huajie Cui, Ning Liu, S.-H. Gary Chan, Yirong Zhuang, Zhipeng Chen
Issue Date:April 2014
pp. 1-16
IPTV services deployed nowadays often consist of both live TV and Video-on-Demand (VoD), offered by the same service provider to the same pool of users over the same managed network. Understanding user behaviors in such a setting is hence an important step...
Toward better indoor localization: cooperative localization and estimation fusion
Found in: Proceedings of the 1st international workshop on Mobile location-based service (MLBS '11)
By S.-H. Gary Chan
Issue Date:September 2011
pp. 51-52
Location-based service (LBS) is believed to be "the next big thing" for mobile applications. Such service depends largely on accurate localization of mobile devices. Though Global Positioning System (GPS) has already achieved good accuracy, it only works i...
Detecting malicious nodes in peer-to-peer streaming by peer-based monitoring
Found in: ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP)
By S.-H. Gary Chan, Xing Jin
Issue Date:March 2010
pp. 1-18
Current peer-to-peer (P2P) streaming systems often assume that nodes cooperate to upload and download data. However, in the open environment of the Internet, this is not necessarily true and there exist malicious nodes in the system. In this article, we st...
