The growing dependence of enterprise networks on Internet connectivity is forcing professional system and network administrators to turn to technologies that they may not fully understand for solutions. This book will provide those connectivity solutions, delivering both an understanding of technology fundamentals and their practical applications. Written for beginning to intermediate network professionals, this book will give readers a framework to assess the requirements and problems of their particular environment, and the information and know-how to build the optimal network for that environment. The content of the book provides the necessary balance between the basics and the practical examples needed to distinguish this book from other professional networking book offerings.
