Providing a satisfactory multimedia service in networking environments requires an effective media delivery mechanism. However, the Internet does not provide a guaranteed network bandwidth to accommodate multimedia service in a reliable fashion. The Internet is a heterogeneous networking environment, in which resources available to multimedia applications are changing. In the last decade, the research community has proposed both networking techniques and application layer techniques, which adapt to the changes in network conditions. This chapter focuses on the application level techniques, including methods based on compression algorithm features, layered encoding, rate shaping, adaptive error control, and smoothing. The chapter also discusses operating system methods to support adaptive multimedia.

The progress of the internet has become the best means to start a property business and it has been proven to be an effective and effective media of information from the internet to disseminate information that is fully accessible to anyone,anytime and anywhere. The great effect on the property business is caused through the internet because only by accessing it from smartphone device and computers at home or in the office of prospective buyers can see property add information.In today’s digital era property sales are mostly done on social media. Social media has many users. But social media has the disadvantages of having to pay if you want to advertise sales, consumers are only users of social media, sales posts quickly sink. In this research, a web-based property sales and leasing information system will be built to cover the shortage.

Digital marketing can help a lot of tourism practitioners, especially the Tourism Village in marketing the tourism village. Along with changes in people's behavior that is more 'internet', the internet media is an effective media in marketing tourism services. Since not all rural communities are familiar with digital marketing, there is a need for community empowerment to develop their Tourism Village through Digital Marketing Management activities.The method of carrying out the dedication by making a program of empowering the skills of tourism aware groups, and also the community of Banyuresmi Village, Jiput Pandeglang. It is hoped that after this program, the community and also POKDARWIS can effectively manage digital marketing (product, price, place, promotion) to develop Kampung Bambu Tourism Village.

With the Internet services increased explosively, the requirement for network bandwidth is rigorous. Upon the extraordinary development of process capability, Memory access control has become a key factor that impacts the performance of network processor. The paper proposed a storage management for fast packet buffers in network processor, which can enhance the utilization of bandwidth. Experiment results shows that this approach improved the rates of accessing to memory system in network processor remarkably.

This book chapter presents the role of telecommunications network in voice and data transmission. Switching, signaling and transmission are the technologies used to carry out this process. In landline call establishment, calls are routed from subscriber handset to a remote switching unit (RSU), a main switching unit (MSU), and to the internet protocol trunk automated exchange (IPTAX). Then, it is directed to the National Internet Backbone (NIB). On the receiver side, the IPTAX receives this signal from the NIB and directs to it to the MSU and RSU, respectively. The receiver side RSU delivers the information to the destination subscriber. In order to transmit the information from one place to other, it undergoes various process like modulation, demodulation, line coding, equalization, error control, bit synchronization and multiplexing, digitizing an analog message signal, and compression. This chapter also discusses the various services provided by BSNL and agencies governing the internet. Finally, it focuses on the National Internet Backbone facility of BSNL, India.

The internet is designed for processing and forwarding of any packet in a best effort manner. The packets carried by the internet may be malicious or not. Most of the time, internet architecture provides an unregulated path to victims. Denial-of-service (DoS) attack is the most common critical threat that causes devastating effects on the internet. The Botnet-based DoS attack aims to exhaust both the target resources and network bandwidth, thereby making the network resources unavailable for its valid users. The resources are utilized by either injecting a computer virus or flooding the network with useless traffic. This chapter provides a systematic analysis of the causes of DoS attacks, including motivations and history, analysis of different attacks, detection and protection techniques, various mitigation techniques, the limitations and challenges of DoS research areas. Finally, this chapter discusses some important research directions which will need more attention in the near future to guarantee the successful defense against DoS attacks.

Human motion animation has been one of the major research topics in the field of computer graphics for decades. Techniques developed in this area help present human motions in various applications. This is crucial for enhancing the realism as well as promoting the user interest in the applications. To carry this merit to e-learning applications, we have developed efficient techniques for delivering human motion information over the Internet to collaborating e-learning users and revealing the motion information in the client machines with different rendering capability. Our method offers a mechanism to extract human motion data at various levels of detail (LoD). We also propose a set of importance factors to allow an e-learning system to determine the LoD of the human motion for rendering as well as transmission, according to the importance of the motion and the available network bandwidth. At the end of the paper, we demonstrate the effectiveness of the new method with some experimental results.
