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.

Three Phases

Situation assessment is a critical skill amongst electricity distribution controllers but can be difficult to assess in practice. In the present research, we adapted a psychometric approach based on the principle that expert situation assessment engages cue-based associations from memory. Using consortium norming, we acquired performance data from 320 network control operators for five network control-related tasks that comprised the electricity network service provider edition of the EXPERT Intensive Skills Evaluation (EXPERTise 2.0) software. Operators were distributed across 11 Distributed Network Service Providers (DNSP), with data collected over three phases. Data were examined across the three phases of data collection and suggest that DNSPs can monitor the situation assessment of network controllers at an individual and at an organisational level, affording the opportunity to identify changes in performance and implement remedial strategies as appropriate.

Use Of Technology

Technological developments have a major impact on user behavior. The rapidly evolving communication system and technology have provided numerous choices for people. The ever-shifting changes in the generation of communication networks have posed challenges for mobile network service providers to attract and retain customers. This study aims to prioritize the determinants of the adoption of mobile network service providers using the unified theory of acceptance and use of technology (UTAUT-2). In this study, data were collected from 660 mobile phone users in Haryana, India. A fuzzy analytical hierarchy process (F-AHP) was applied to arrange the priority or rank the factors based on the significance of the factors in explaining the adoption of mobile network service providers. Results of the study reveal that efforts expectancy is the highest-ranked and prioritized factor for the adoption of mobile network service providers followed by performance expectancy and facilitating conditions. However, social influence emerged as the least important factor. The present study provides theoretical implications for future researchers by synthesizing and prioritizing the important factors affecting technology acceptance. The practical implications offer a clearer insight to marketers for developing focused pragmatic strategies to retain customer loyalty. The study has considered only UTAUT-2 model constructs and used the F-AHP technique. Other factors may be considered in future studies. Other priority analysis techniques can also be used such as ISM and MICMAC analysis for further study. The research has been conducted in Haryana, India, and therefore, it needs to be tested in other areas/countries for generalizability. JEL Classification: O1, O2, O4

Service Oriented

In Service-Oriented Computing, service providers publish their services by deploying service components which implement those services into a network. Since such services are distributed around the network, Service-Oriented Computing requires the functionality to discover the services that meet certain criteria specified by an end user. In order to overcome the scalability issue that the current centralized discovery mechanism inherently has, distributed discovery mechanisms that the P2P research community has developed may be promising alternatives. This chapter outlines existing distributed mechanisms and proposes a novel discovery mechanism that utilizes end users’ preferences. The proposed mechanism allows end users to return their feedback that describes the degree of the preference for discovered services. The returned preference information is stored at nodes and utilized to decide where to forward subsequent queries. The extensive simulation demonstrates that the proposed mechanism meets key requirements such as selectivity, efficiency and adaptability.

Delivery Networks

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.

As computer networks, specifically the Internet, become more and more integral to business and society, the performance and availability of services on the Internet become more critical. It is now a common need to provide a reliable network service to millions of Internet users and customers. The performance of these services is commonly a key factor in their success. Web portals and popular sites build relationships with customers based in part on their speed and availability. Even services internal to an enterprise frequently have serious consequences if there is a loss of availability. This chapter discusses how advanced, multilayer switches can be used to increase the performance of network services. For this discussion, the term “performance” refers to availability, latency, and throughput, since all of these factors affect a user’s impression of a site’s performance. This chapter is intended for network service providers who must scale their services, network administrators who need to apply policies to their networks, and developers of switches who need to understand what the utility and requirements for these switches are. It is assumed that the reader has a working familiarity with networking principles, but substantial background information is also provided.

As the content delivery network becomes widely-used, storage has emerged as a typical kind of service in the cloud environment. This paper conducted a research on the management issues for such applications, and implemented some meta-services upon the underlying cloud services. The architecture of the system was described in detailed and the detailed design of four types of meta-services was further discussed. Experiments show that the implemented prototype can work effectively and meaningful suggestions could be given according to users’ requests, and thus depict the advantages of employing the proposed meta-services.

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.
