Application Level Multicast

Firstly challenges in P2P media streaming applications were pointed out, then some recent research results such as application-level multicast tree, heterogeneity of network and incentive mechanism and so on were introduced. This paper has proposed a new model of application level multicast named DHCM (density-based hierarchical clustering multicast)which has improved IHC arithmetic．DHCM divides the hosts into many hierarchies according to their density，and constructs a density tree to realize the shortest routing．The tree delivers the content of video server to each host in density tree and uses a P2P scheme in data transmission．By this way the application-level multicast has been realized．This density tree has the homogeneity and monotonic properties．The experiment result has proved that DHCM can transmit the video stream efficiently and robustly.

Strategic Procurement

The purpose of this chapter is to illustrate the application of advanced data analytics in the domain of strategic procurement and its effects on processes, people, and on the procurement business model itself. Advanced data analytics are generally accepted as being one of the key enablers for organisations to build their capabilities to adapt quickly and navigate through volatile business circumstances successfully. Strategic procurement is in a pivotal position in a network of external suppliers and internal stakeholders, and thus ideally positioned to benefit from the introduction of advanced data analytics. However, to date, the application of these technologies has been limited, and clear evidence of benefits delivery is yet to be demonstrated. This chapter draws upon research results from a detailed case study in the aviation industry to assess the benefits of advanced data analytics in the strategic procurement function and puts forward a maturity model of relevance to both researchers and procurement professionals.

E-Banking is an inevitable trend of banking industry in the future, it brings about benefits not only for the banks but also for customers. The studies showed that, different patterns of EBanking is essential to match specific countries and the popularity of E-Banking products to customers. This study proposes a new model that is the adoption and usage of E-Banking in Vietnam (E-BAM, EBanking Adoption Model). Research results showed that all hypothesis of E-BAM would be accepted. EBAM explained the data reasonably well, with 57% of the total variance in the adoption and usage of EBanking.

Network Scalability

In recent years, there has been considerable interest in applying Distributed Hash Tables (DHTs) to application-level multicast since DHTs have many advantages that are good for multicast applications: decentralization, scalability, fault tolerance, load balancing, and good routing performances. However, an effective bandwidth utilization method is required for DHT-based multicast systems because of a number of technical issues such as heterogeneous node capacity and dynamic membership. In this paper, the authors propose their BAM-Chord (i.e., Bandwidth Adaptive Multicast over Chord), a DHT-based multicast system that focuses on host heterogeneity, network scalability and effective bandwidth utilization. In the authors’ system, when a node joins into the system, it will find out an appropriate position (i.e., node identifier) on a BAM-Chord ring and create links to neighbor nodes based on node’s bandwidth capacity such that the multicast tree can be built efficiently and balanced. Therefore, their system can utilize bandwidth of every node efficiently to reduce the depth of the multicast tree, increase network scalability and take advantages of DHTs in maintaining the multicast tree.

Client Server Architecture

A VoD system is typically implemented by a client-server architecture supported by certain transport networks such as telecom, CATV, or satellite networks. The simplest scheme is to dedicate a channel to each client. Many VCR-like functions may be provided (e.g., forward, rewind, pause, search, etc.). Since video is an isochronous medium, the video server has to reserve a sufficient amount of network bandwidth and I/O bandwidth for each video stream before committing to a client’s request. Apparently, such systems may easily run out of channels because the growth of the number of channels can never keep up with the growth of the number of clients. To solve this problem, many schemes have been proposed to resolve the bandwidth problem. In this chapter, we review two kinds of broadcasting schemes. The first one is the batching scheme, in which a set of viewers arriving close in time will be collected and grouped together. Then the video server will serve them altogether with one channel. The second one is the periodic broadcasting approach. The server uses multiple dedicated channels to cooperatively broadcast one video. Each channel is responsible for broadcasting some portion of the video. Each client follows some reception rule to grab data from appropriate channels so as to play the whole video continuously. The server’s broadcasting activity is independent of the arrivals of requests. Such an approach is more appropriate for popular or “hot” videos that may interest many viewers during a certain period of time.

P2p Applications

P2P applications have become enormously popular and currently take into account a large majority of the traffic transmitted over the Internet. A unique characteristic of P2P networks is their flexible and robust operation, which is enabled by the peers’ ability to serve as both servers and clients. Thus, P2P networks are able to provide a cost effective and easily deployable solution for sharing large files among participating peers with no significant help from a de facto, centralized infrastructure. Due to these advantages, P2P networks have also recently become popular for multimedia streaming. The requirements for general file sharing and real-time media streaming are very different and thus, we discuss in this chapter solutions for both these applications. We begin the chapter with an overview of various P2P network structures and their advantages and disadvantages. We then present in detail the BitTorrent system, which is one of the most popular file sharing protocols. We then overview existing P2P-based media streaming applications, and discuss mechanisms that have been developed to support such applications. We also discuss state-of-the-art research in P2P networks which is based on several game theoretic approaches.
