With great technologies, emerge new needs and requirements. The progress achieved in Access broadband rates accentuated the demand on IPTV (Internet Protocol Television) services specially Video on Demand (VOD) and Time Shift TV (TSTV) which led subsequently to a great need for efficiency in the use of bandwidth consumed by those services. Optimization solutions are considered by IPTV service providers to lighten the service load especially on Access Nodes uplinks. This paper describes an optimization of TSTV dedicated bandwidth based on a peer-assisting TSTV content delivery, a solution in which the users STBs (set-top-boxes) assist the central TSTV servers in the service fulfillment. For this purpose, for each TSTV request, the STB will be receiving the TSTV stream from a neighbor STB instead of the central server. By using this method, the unicast traffic will not pass through the IP network; it will be a peer-to-peer communication within the access network. Extensive simulation results were included to illustrate the validity of the proposed new solution.

Channel change time is a critical quality of experience (QOE) metric for IP-based video delivery systems such as Internet Protocol Television (IPTV). An interesting channel change acceleration scheme based on peer-assisted delivery was recently proposed, which consists of deploying one FCC server (Fast Channel Change Server) in the IP backbone in order to send the unicast stream to the STB (Set-Top Box) before sending the normal multicast stream after each channel change. However, deploying such a solution will cause high bandwidth usage in the network because of the huge unicast traffic sent by the FCC server to the STBs. In this paper, we propose a new solution to reduce the bandwidth occupancy of the unicast traffic, by deploying the FCC server capabilities on the user STB. This means that, after each channel change request, the STB will receive the unicast traffic from another STB instead of the central server. By using this method, the unicast traffic will not pass through the IP network; it will be a peer-to-peer communication via the Access Network only. Extensive simulation results are presented to demonstrate the robustness of our new solution.

Where lucrative media rights deals for sports content currently lie primarily with pay TV and free to air (FTA) broadcasters, Internet Service Providers (ISPs) entering the content delivery market through partners such as Fetch TV may be better placed to compete for distribution rights to sporting and other live events. In response to this shifting environment this paper outlines the technological capacities of NBN-based multicast Internet Protocol Television (IPTV), and examines public comment and interview data from ISPs, sports organisations and NBN Co. regarding their intentions for IPTV delivery. This paper begins with the assumption that diversity in these emerging media forms remains important as ISPs enter the media content market. We demonstrate, however, that despite the emergence of NBN-based technologies, diversity in sports content distribution cannot be assumed. The paper points toward the important role that regulators, such as the ACCC, have in maintaining diversity and competition in IPTV services.

Popularity Prediction

Video on demand (VoD) service in IPTV is a bandwidth-hungry application. It has been argued that the distribution of popularity of videos can be well measured using a Zipf-like distribution in which top 10% of the videos account for nearly 90% of requests. In this article, we propose a neural network based method to predict the popularity of videos in an IPTV system. The popularity prediction can be used by service providers for video placement in content delivery systems or hierarchical servers and hence it can lead to bandwidth save. Simulation-based performance evaluation of our proposed method confirms a significant accuracy in the prediction of the popularity of the videos.

The continuous growth of internet traffic is significantly pushed by emerging high bandwidth demanding contents. All participants in the content provisioning process including content providers, service providers, Content Delivery Networks (CDN) and customers are influenced by bandwidth requirements. Appropriate bandwidth demand estimation is of great importance for addressing resource investment. Providers in content provisioning process need to consider cloud migration in order to minimize costs. The vertical interconnection between involved providers is necessary. Larger undertakings often perform vertical integration, thus ensuring a higher control over different segments of the process. The vertically integrated content provider's incentives for cloud migration can induce significant changes in interconnection contracts in the content provisioning process. In this chapter different methods of vertical interconnection charging among vertically integrated providers are analyzed and compared.

P2p Live Streaming

The rapid evolution of the telecommunication domain increases the performance of different access networks continuously. New services, especially in the domain multimedia content distribution, require higher and higher bandwidth at the user’s and service provider’s side. Multimedia services like Video on Demand, IPTV, and live streaming were introduced in the past and are still improved in quality and quantity. Multimedia streams and Peer to Peer (P2P) file sharing dominates the worldwide Internet traffic nowadays and will continue further (Schulze, 2009). The user acceptance of enjoying multimedia content over the Internet will grow steadily together with the increasing quality of the available multimedia content. Network operators and service providers have to face the growths by increasing their service platform with higher performance and bandwidth or introducing a scalable solution. In this paper, the authors present an algorithm for scalable P2P live streaming in Next-Generation-Networks (NGN) that addresses this challenge. An evaluation proves the performance of the implementation of this algorithm in a demo scenario.

Further Development

With the development of data transmission networks Internet service providers implement solutions of the OSS/BSS class (Operations Support Systems / Business Support Systems) every year. The integration of different elements of the information and communication network takes place due to the system data, but some issues require further development. Integrated accounting of the technical and socio-economic information is being considered while solving problems of data transmission network design. The aim of the work is structuring the design process of the optical access networks of the Internet provider. Optical access networks based on PON and FTTB technologies have been chosen as the object of study. When executing projects, many factors are to be considered, such as: subjectivity of the designers, level of their competence, interest in using certain technologies by specific groups of designers. To reduce the influence of such factors, it is recommended to apply methods of accumulating and processing information associated with successful or unsuccessful experience of implementing previous projects. Using the system analysis methods and IDEF0 diagrams, a similar design task is structured in the form of diagrams of a draft project and a detailed design, for which groups of variables have been identified. The output values of the diagrams are the intermediate and final assessments of the project, which allows the decision maker to determine feasibility of the subsequent stages of the project implementation. Realizing the proposed provisions shows the opportunities for further development of OSS/ BSS systems in terms of automation of the decision-making support process associated with the selection and practical implementation of access network projects.
