Best book in print for designing e-business networking systems. This book leads a designer of E-business solutions through the steps necessary to ensure QoS objectives are meet, performance requirements are satisfied, and networks aren't over engineered. As an instructor of E-commerce Network Engineering for the Univeristy of California, I'm familar with current published literature, and there isn't anything out there that compares in clarity and completeness. This is Daniel Menasce's third book on the subject, and his best by far. On my short list of must read books for network engineers and system architects of E-business solutions.
