Teresa C. Piliouras , Kornel Terplan. Network Design outlines the fundamental principles and analytical techniques used in designing data networks.
The text enables future managers and technical professionals to better understand and appreciate each other's perspective in the network design process. Network managers will need a sound grounding in basic design principles to effectively manage, plan, and assess the plethora of new technologies and equipment available for designing networks. They also must understand how requirements should be formulated and specified for design engineers. Managing QoS in the face of constantly changing operating conditions demands dynamic management approaches that span multiple layers in the protocol stack.
Such cross-layer design approaches have recently received attention in the context of cellular and mobile ad hoc networks. However, there are still a wide range of opinions and definitions about what exactly CLD entails, and there is no fundamental guidance concerning how to apply CLD techniques in various environments. In this article we introduce the notion of network predictability and describe its relationship to achievable QoS.
This relationship is used to propose a framework for CLD that can be used to guide development efforts and direct investment decisions for future military networks. The framework also contains the notion of a crosslayer coherence length, which determines the protocol layers across which the highest degree of coupling, or correlation, should be present in order to realize the greatest possible gains in achievable QoS.

This helps the operation to decide how it wants to influence the overall shape of its network, the location of each operation, and how it should manage its overall capacity within the network. Why should an organization take a total supply network perspective? The supply network perspective Supply network: A supply network perspective means setting an operation in the context of all the other operations with which it interacts, some of which are its suppliers and its customers.
Materials, parts, other information, ideas and sometimes people all flow through the network of customer—supplier relationships formed by all these operations. Supply side: An operation has its suppliers of parts, or information, or services.

These suppliers themselves have their own suppliers who in turn could also have suppliers, and so on. Demand side: The operation has customers. They are supplied by second-tier suppliers. However, some second-tier suppliers may also supply an operation directly, thus missing out a link in the network.
Why consider the whole supply network? Immediate customers and immediate suppliers, quite understandably, are the main concern to competitively minded companies. Yet sometimes they need to look beyond these immediate contacts to understand why customers and suppliers act as they do. Alternatively, it can look beyond its immediate customers and suppliers.
It helps identify significant links in the network. The key to understanding supply networks lies in identifying the parts of the network which contribute to those performance objectives valued by end-customers.

Any analysis of networks must start, therefore, by understanding downstream end of the network. After this, the upstream parts of the network which contribute most to end-customer service will need to be identified. But they will not be equally significant.
