High-quality content can be distributed and shared efficiently in community networks by the advantages of the geographical coverage and the connected community members. Recently, we have proposed a Personal video recorder (PVR)-based community network employing the multiple-loop fiber channel arbitration loop (FC-AL) connection, which can provide the scalability without using expensive FC-AL switches...
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...
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...
Peer-to-Peer (P2P) networks risen as a promising approach to provide large-scale VOD services over the Internet for their potential scalability. Since videos are typically large in volume and require high communication bandwidth for delivery, many peers are unwilling to cache them in whole for serving others. In this paper, we propose a new time-based cache management on peers and a peer clustering...
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 SIP (P2PSIP) based server farm is proposed to provide distributed solution of multimedia applications. In this paper, we focus on the bandwidth requirements of both DHT and SIP packets from the perspective of a single server node in P2PSIP based server farm to quantitatively evaluate the overhead caused by distributed architecture. Furthermore, the efficiency of server node is also studied...
This paper presents a novel video service system DCSVS (distributed collaborative set-top-box video service), which encompasses several practical and effective solutions to both live and VoD (video-on-demand) services. DCSVS is established on an overlay DHT (distributed hash table) network, which improves Kademlia protocol to fit for real-time application. We use several types of pre-fetching to enhance...
In this paper we discuss on adaptive caching techniques in peer-to-peer network. We have made an extensive survey on the different adaptive caching techniques in peer-to-peer network like Squirrel, Tuxedo and PeerOLAP. Vast improvement can be made in the caching of the peer-to-peer network. We observed that combining and interchanging different methods used in different techniques results in a better...
Nowadays, sharing multimedia contents in P2P systems has become a common practice. In general, it is done in "download" mode as any other type of data. However, due to their huge volume and real time constraint, multimedia data present another consumption mode which is the streaming mode. In this mode, rather than downloading the entire data before viewing it, it initiates a stream from...
