“…Consider IPTV, a video service that has been proposed for traditional broadcast, Video on Demand (VoD) and interactive video services, i.e., video delivered digitally over the converged IP networks [5]. These services can be distributed by a telecom carrier or an Internet Service Provider (ISP) [6].…”

“…Since different video services are considered by IPTV, the latter is expected to have an important amount of subscribers generating high amounts of traffic in the Internet, which in turn may cause congestion problems at the ISP or telecom company [5], [9]. In this context, P2P networks have drastically increased the capacity of these services [2], [3], [5], [9], [13].…”

Peer-to-Peer (P2P) networks are distributed systems where no central authority rules the behavior of the individual peers. These systems rely on the voluntary participation of the peers to help each other and reduce congestion at the data servers. BitTorrent is a popular file-sharing P2P application originally designed for non real-time data. Given the inherent characteristics of these systems, they have been considered to alleviate part of the traffic in conventional networks, particularly for streaming stored playback Video-on-Demand services.In this work, two strategies for implementing a streaming service for stored playback video are presented and studied through simulations at the chunk level. First, a window-based peer selection strategy for P2P networks is proposed that greatly improves the chunk sharing process for such video services. The basic idea is to select the downloader peers according to their progress in the download process. Second, a priority scheme is proposed and analyzed that benefits the peers that are more likely to remain longer in the system by serving them first. The simulation model offers complementary results to the conventional fluid or Markovian models.

“…Currently, a number of major telecom operators worldwide are offering IPTV services to their subscribers, such as AT&T, BT, Deutsche Telekom, Orange, Fastweb, PCCW, KT, Chunghwa Telecom, to name a few ( [2], [3]). Meanwhile, to fulfill the ultimate goal of digital convergence, telecom and cable operators are devoting to the deployment of Next Generation Networks (NGN), in which services are unbundled from the underlying transport networks [4].…”

Internet Protocol Television (IPTV) is a promising technology which plays a key role in the triple play service over the next-generation networks (NGN). In NGNs, services are no longer bundled with transport networks; this feature opens a new window for researchers to develop innovative applications in the context of cloud computing. Specifically, in this research we demonstrate the concept of Communications-as-a-Service (CaaS) in cloud computing by proposing a network-based multicast IPTV audience measurement scheme as an application for IPTV distribution platforms. The scheme makes use of the standard Internet Group Management Protocol (IGMP) and Simple Network Management Protocol (SNMP), so upgrading the existing network equipments is not required. Compared with measurement schemes that collect data from the set-top boxes directly, the network-based scheme not only scales well when the audience is large, but also applies smoothly to heterogeneous network environments. We also discuss the potential services that the network-based IPTV audience measurement scheme can offer, and conducted laboratory trials in Chunghwa Telecom Labs. Although this work is by no means a technological breakthrough, we believe that this paper may shed some light on the research of creative cloud-based applications.
