Quality of Service is expected to become the most important communications topic in the new millennium.<br> <br> The acclaimed author, Gilbert Held, provides a comprehensive guide to obtaining a Quality of Service (QoS) capability in a Cisco hardware environment.<br> <br> Today there are many aspects of the QoS 'puzzle' and Cisco is providing users with a wide range of solutions. Some solutions are well known but do not scale for use on the Internet or on a large corporate Intranet. Other solutions must be used in conjunction with different schemes for true end-to-end QoS. That is where this book comes in, providing a guide to the various pieces of the QoS puzzle.<br> <br> Quality of Service in a Cisco Networking Environment:<br> * Is a one-stop location to obtain complete and concise information about achieving QoS for applications transported over local and wireless area networks.<br> <br> * Provides a tutorial on the operation of different QoS techniques (IEEE 802.1p, 802.1Q, Differentiated Services, and RSVP).<br> <br> * Describes Cisco Router QoS and Switch QoS commands.<br> <br> * Gives examples of QoS configurations.<br> <br> * Includes a series of easy to implement IP and Frame Relay traffic enhancement techniques.<br> Written for the local and wide area network planners and managers, local area network administrators and router administrators, every chapter initially guides the reader through the theory behind a specific QoS technique. This information is then followed with a series of Cisco command examples tailored to a specific QoS technique. Readers learn both how a QoS technique operates and how to place it into effect in a Cisco environment.
In most schools the dominant supporting technology has been either the stand-alone personal computer or a modest local network. The situation is changing rapidly as a rising number of schools provide access to the Internet for their staff and pupils, opening avenues for communication and networking hitherto not possible. This book reflects on this change. It aims to further the vision of how these new technologies could improve and transform aspects of education. Yet in parallel it asks serious questions about the realities of an interface between the social, cultural and pedagogical contexts of education and the actual affordances that these new information and communication technologies offer. The chapters in this book provide a heady mix of foresight and practical reporting, of planning for the future but at the same time respecting the problems education already has with current technologies. The richness of the points presented here stems in part from the range of experience of the international authors - from academics and administrators, to teachers and curriculum designers. This mix ensures that the central questions on communications and networking in education are considered not simply from a variety of personal perspectives, but also from different cultural and environmental experiences. And yet interest also lies in the commonality of reporting and discussion based on activity in the field. All the contributions draw heavily on research and experience in devising and running projects and experimental activities in a range of schools and teacher-training institutions and environments. The opinions expressed are thus grounded in knowledge gained from work embedded in the reality of today's educational settings. This must be the only sound base upon which to consider the issues of the future. This book is essential reading for all professionals involved in all aspects of information and communication technologies in education. Teachers, lecturers, researchers, students and administrators will find it invaluable.
Recent advancements in mobile device technologies are revolutionizing how we socialize, interact, and connect. By connecting the virtual community with the local environment, mobile social networks (MSNs) create the opportunity for a multitude of new personalized services for mobile users. Along with that comes the need for new paradigms, mechanisms, and techniques with the capacity to autonomously manage their functioning and evolution.
