The Internet architecture lacks natural support for contentcentric applications, which are dominating Internet usage today. This led to the design and development of a plethora of application-specific and incompatible solutions for content distribution, e.g., content-delivery networks and peer-to-peer. More recently, information-centric architectures have been proposed to address the root causes of...
Mobile video is becoming extremely popular, and P2P mobile video platforms are being considered for large-scale deployment in this context. However, the design and deployment of realistic P2P video systems have to consider specific characteristics of mobile networks. In this article, we look from the viewpoint of a large-scale commercial P2P mobile video provider system, PPTV, and describe the implementation...
Multi-hop wireless mesh networks (WMNs) are emerging as a promising technology with applications in last mile Internet access, public safety, disaster response, battlefield, etc. The unique characteristics of WMNs such as limited and dynamic bandwidth, error prone nature, interferences, and user mobility, however, pose a number of significant challenges for high quality video streaming. In this paper,...
Video-on-demand (VoD) services have attracted a lot of attentions in recent years. Measurement studies show that VCR (video cassette recorder) operations, such as pause, rewind, and fast forward/backward, influence the pattern of the access to video segments and viewer(session) sojourn time. Moreover, some VCR features (e.g., bookmarking) newly proposed can further magnify such effects. This work...
Peer-to-peer (P2P) technology has recently been employed to deliver large scale video multicast services on the Internet. Considerable efforts have been made by both academia and industry on P2P streaming design. While academia mostly focus on exploring design space to approach the theoretical performance bounds, our recent measurement study on several commercial P2P streaming systems indicates that...

Existing approaches to P2P streaming can be divided into two general classes: (i) tree-based approaches use push-based content delivery over multiple tree-shaped overlays, and (ii) mesh-based approaches use swarming content delivery over a randomly connected mesh. Previous studies have often focused on a particular P2P streaming mechanism and no comparison between these two classes has been conducted...
