This book provides an all-important connection to the actual realities of designing a communication network for optimizing demand (traffic).

Pioro and Medhi's book is very refreshing and gives a comprehensive view of network design. It unifies many important topics on network design that are not found in one place; for example, this book provides the first thorough treatment of multi-layer design. Practitioners will find the book useful due to its development of both models and algorithms that are more applicable to real-world problems.
