  • IP Mobility This chapter will provide an overview of IP mobility. It aims to be pretty selfcontained, and so should stand alone fairly independently of the other chapters. IP mobility is very important, because it is predicted that the vast majority of terminals will be mobile in a few years and that the vast majority of traffic will originate from IP-based applications. The challenge of ‘IP mobility’ is to deliver IP-based applications to mobile terminals/users, even though, traditionally, IP-protocols have been designed with the assumption that they are stationary...

  • This report provides a brief overview of several important techniques for media broadcasting and stream merging, as well as a discussion of traditional IP multicast and overlay multicast. Additionally, we present a proposal for a new distribution system, based on the broadcast and stream merging algorithms in the BitTorrent distribution and replication system.

  • TECHNOLOGIES SUPPORTING VoIP1 In this chapter, we discuss and review various standard and emerging coding, packetization, and transmission technologies that are needed to support voice transmission using the IP technologies. Limitations of the current technologies and some possible extensions or modifications to support high-quality—that is, near-PSTN grade—real-time voice communications services using IP are then presented. VOICE SIGNAL PROCESSING For traditional telephony or voice communications services, the base-band signal between 0.3 and 3.

  • VoIP FOR GLOBAL COMMUNICATIONS1 This Chapter discusses how IP-based voice communications can be deployed for global communications in multinational enterprises and for international calling by residential PSTN customers. In traditional PSTN networks, various countries use their own version of the ITU-T standards for signaling or for bearer or information transmission. When IP-based networks, protocols, interfaces, and terminals (PCs, IP phones, Web clients, etc.) are used, unification of transmission, signaling, management, and interfaces can be easily achieved....

  • Even since computers were invented many decades ago, many researchers have been trying to understand how human beings learn and many interesting paradigms and approaches towards emulating human learning abilities have been proposed. The ability of learning is one of the central features of human intelligence, which makes it an important ingredient in both traditional Artificial Intelligence (AI) and emerging Cognitive Science.

  • A clickbot is a software robot that clicks on ads (issues HTTP requests for advertiser web pages) to help an attacker conduct click fraud. Some clickbots can be purchased, while others are malware that spread as such and are part of larger botnets. Malware-type clickbots can receive instructions from a botmas- ter server as to what ads to click, and how often and when to click them. There are many types of clickbots used on the Internet. Some are “for-sale” clickbots, while others are malware.

  • The deregulation of the telecommunications industry, creating pressure on new operators to innovate in service provision in order to compete with existing traditional telephone service providers, is and will be an important factor for an efficient use of the spectrum. It is certain that most of the information communicated over future digital networks will be data rather than purely voice. Hence, the demand for high-rate packet-oriented services such as mixed data, voice, and video services, which exceed the bandwidth of conventional systems, will increase.

  • Video surveillance has been a key component of many organizations’ safety and security groups for decades. As an application, video surveillance has demonstrated its value and benefits countless times by: ● Providing real-time monitoring of a facility's environment, people, and assets. ● Recording the movements inside and outside a facility's environment for delayed viewing. Many traditional video surveillance deployments are purely analog and have not yet been able to benefit from a converged network approach.

  • Modern WAN architectures require additional network capabilities to support current higher bandwidth and mission-critical applications. Requirements for deploying voice over IP (VoIP) and video conferencing include high availability, IP multicast, and quality of service (QoS). Today, most enterprises rely on private WAN connections such as Frame Relay, ATM, or leased-line services to connect their businesses.

  • The economic drivers for voice and data integration using voice over IP (VoIP) are catching the attention of CFOs, CIOs and others involved on the cost side of any business. This white paper will show the cost justification for voice and data network integration and how much increase in bandwidth will be necessary once voice traffic is added to the traditional data traffic being carried across a wide area network (WAN).

  • The term AAA has been traditionally used to refer to Authentication, Authorization, and Accounting activities. All of those activities are of crucial importance for the operation of an IP network, although typically they are not so visible to the end user. The importance of AAA functions lies in the fact that they provide the required protection and control in accessing a network. As a consequence, the administrator of the network can bill the end user for services used.

  • Traditionally, firewalls use IP addresses to monitor traffic and are unaware of the user and machine identities behind those IP addresses. Identity Awareness removes this notion of anonymity since it maps users and machine identities. This lets you enforce access and audit data based on identity. Identity Awareness is an easy to deploy and scalable solution. It is applicable for both Active Directory and non-Active Directory based networks as well as for employees and guest users.

  • The traditional hierarchical structure of cellular networks has led to deployment models which are heavily centralized. Mobility management with centralized mobility anchoring in existing hierarchical mobile networks is quite prone to suboptimal routing and issues related to scalability. Centralized functions present a single point of failure, and inevitably introduce longer delays and higher signaling loads for network operations related to mobility management.
