Excerpt from Using a Hop-Constrained Model to Generate Alternative Communication Network Designs
This paper presents a methodology to support topological design and link capacity planning decisions for the backbone network interconnecting geographically dispersed gateway nodes and switching centers in a telecommunication system. Topological design decisions are very important in backbone network planning because Of the enormous capital investments required for transmission and switching facilities, and the significant impact Of network configuration choices on service levels. In selecting the configuration and capacities for a backbone network, planners face conflicting objectives Of reducing the total investment and operating costs while ensuring adequate service levels, expressed in terms Of network performance measures such as reliability and vulnerability, alternate routing capabilities, blocking probabilities, and queueing and transmission delays. With increasing competition and service diversity in the communications sector, these service considerations are becoming increasingly important.
Because Of the multiple, conflicting objectives, non-linearities in service criteria, and discrete design choices, formulating and solving a comprehensive Optimization model to support backbone network planning decisions is impractical. Indeed, even with a single objective such as cost minimization, the design task is very complex and challenging because the decision model must (i) incorporate binary network design decisions to capture the significant fixed costs, and (ii) simultaneously account for the close linkages between topological design, link capacity, and routing decisions.

Paperback. Condition: New. Print on Demand. This book presents a groundbreaking approach to network design for communication systems. The author proposes an optimization-based methodology that generates cost-effective backbone network designs with varying performance characteristics. The method uses hop constraints, which restrict the number of links that messages can be transmitted over, to generate alternative network topologies. The author describes a Lagrangian-based algorithm to solve the resulting optimization problem, and demonstrates its effectiveness through extensive computational tests. The book also explores model extensions to incorporate buffer capacities and alternate routes, providing a comprehensive framework for telecommunication network planning. This innovative approach empowers network planners to assess cost-performance trade-offs and select designs that balance investment and service levels, ensuring optimal network performance. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
