"Without a doubt, Tony Kenyon is one of today's foremost technical authorities in the area of network design. High-Performance Data Network Design cements this position, and provides the most complete guide for networking professionals of all levels involved in the design and maintenance of medium to large networks. A book far more likely to be open on the desk than adorning a shelf."?Phil Miller, Nokia Internet Communications, author of TCP/IP Explained and LAN Technologies Explained, published by Digital Press "This book is essential reading for anyone involved in the design, deployment and support of any network. The content is not just theoretical, it is based on extensive practical experience and the writing style makes complex subjects compelling reading. Having been heavily involved with the development of a network topology design and costing tool in previous employment, it is refreshing to find a book that covers these topics and others in such depth. Not only are there excellent chapters on capacity planning, queuing and modeling (many with worked examples), but here, in one book, you can find in depth material on Local Area, Wide Area and Metropolitan Area Networks, including extensive coverage of technologies like ATM."?Bob Brace, VP of Marketing, Nokia
