Software-defined networking aims to change the inflexible state networking, by breaking vertical integration, separating the network’s control logic from the underlying routers and switches, promoting (logical) centralization of network control, and introducing the ability to program the network. Consequently, SDN is an important key for resolving aforementioned difficulties.

The thesis aims to propose some control techniques for mobile target Robot-camera. After that, I studied some of the torque control techniques of joints for the Robot-camera system sticking to the mobile target and the Robot-camera system, paying attention to the motivating motor sticking to the mobile target. Finally, the author also proposed some control algorithms for Robotic-camera arm system with irregular model, external noise and preventing system degradation, using nonlinear sliding controller (TSMC) in combination with Artificial neural networks to estimate uncertain numbers.

The telecommunications access network is the section of the network that connects the local exchange to the customers. At present most of the access network is composed of low bandwidth copper cable. Electronic communications are becoming an essential feature of life both at home and at work. The increasing use of applications that require larger bandwidths (such as the internet and video on demand) are making the copper infrastructure inadequate. These demands could be met using optical fibre technologies....

Telecommunications is a vital and growing area, important not only in its own right, but also for the service it provides to other areas of human endeavour. Moreover, there currently seems to be a demand for an ever-expanding set of telecommunication services of ever-increasing bandwidth. One particular technology that has the potential to provide the huge bandwidths necessary if such broadband services are to be widely adopted, is multiwavelength all-optical transport networks (Mukherjee, 1997)....

In line with the rapid growth of telecommunications networks in recent years, there has been a corresponding increase in the level of network complexity. Consequently, it is now generally accepted that advanced computer aided simulation and analysis methods are essential aids to the management of large networks. The 1990s will be recalled as the decade of business process re-engineering

Evolutionary Methods for the Design of Reliable Networks Alice E. Smith and Berna Dengiz Introduction to the Design Problem The problem of how to design a network so that certain constraints are met and one or more objectives are optimized is relevant in many real world applications in telecommunications (Abuali et al., 1994a; Jan et al., 1993; Koh and Lee, 1995; Walters and Smith, 1995), computer networking (Chopra et al., 1984; Pierre et al., 1995), water systems (Savic and Walters, 1995) and oil and gas lines (Goldberg, 1989).

Optimization Issues in Telecommunications The complexity and size of modern telecommunications networks provide us with many challenges and opportunities. In this book, the challenges that we focus on are those which involve optimization. This simply refers to scenarios in which we are aiming to find something approaching the ‘best’ among many possible candidate solutions to a problem. For example, there are an intractably large number of ways to design the topology of a private data network for a large corporation....

Public Networks and Telecommunications Service Providers Historically, telecommunications networks have been run by state-owned organizations, who have operated as legally protected monopolies. These organizations tended run telecommunications to in a manner similar other public utility services (electricity, gas, water, etc.), providing only a few to very basic services, but in a reliable and well-engineered fashion, and available at almost any location to anyone who cared to apply.

Technical Standards for Networks In the past, telecommunications networks have been evolved in the minds of their designers to meet well defined but changing user demands. These broadly innovative influences are bound to persist and users can look forward toever more sophisticated telecommunications services in the future.

Charging and Accounting for Network Use So far we have concerned ourselves entirely with the technical and operational side of running networks and providing telecommunications services. Network operators, if they wantto stay in business, also need to think about capital and operational costs, and how to recover them from their customers.

Introduction to Signal Transmission and the Basic Line Circuit To make it suitable for carriage over most telecommunications networks, information must first be encoded in an electrical manner, as anelectrical signal.
