Nowadays many IPTV services are deployed based on P2P structure for the sake of saving the cost of server equipment and bandwidth requirement. Since peers may join and leave the P2P system arbitrarily, it may cause the service quality unstable. In this paper, we compare IP addresses to find partner peers in proximity, and use specific packet pairs to probe partner peers that have larger bandwidth,...
IPTV is an emerging Internet application that pumps heavy video traffic to both access networks and ISP backbones. Due to the lack of commercial deployment of IP multicast, huge volume of streaming traffic may overload the servers. Hence, P2P IPTV distribution becomes popular and advances quickly. P2P IPTV uses two approaches: tree-push and mesh-pull. The latter has experienced a number of successful...
The WiMAX features longer transmission distance and more accomplished support of QoS than other wireless access technologies such as 802.11. Since the standard did not specify the QoS based packet-scheduling algorithms which run on the base stations, those algorithms are open for alternative implementations. In this paper, we propose a scheduling algorithm for burst traffic in the WiMAX base station...
Due to the increasing volume of multimedia traffic on the Internet nowadays, the traditional client-server architecture may face scalability and deployment cost problems when the number of subscribers grows large. To tackle these problems, more and more media streaming services, such as IPTV are deployed based on Peer-to-Peer (P2P) architecture. According to the current Internet infrastructure, most...
