How Much of an Investment Should Your Network Be?
Obviously, you don’t want to break the bank with your network infrastructure, but you shouldn’t take shortcuts either. For example, home network hardware isn’t meant to handle the same amount of information as commercial-grade network hardware, but not all commercial hardware is meant for large corporations. You want to operate within your budget while getting hardware that will manage what you need for your company now and within projections for the next few years, so you want to make sure your network infrastructure is easily scalable. Find the quality of components that will last your company for several years without having expensive features that you will likely never use.

What is scalable network design?
In fact, what can be considered as a successful scalable network is not only measured by the network size factor but also by how stable and reliable the net-work is and how easily this network can be managed and troubleshot. For example, a network may be designed in a way that can expand to thousands of routers, but at the same time, a failure in one link or device can introduce a high degree of processing and CPU utilization across the network, which may lead to instability. This design cannot be considered a successful scalable design, even though it can grow to a large number of routers. Similarly, a network may be designed to grow to a large scale while at the same time being difficult to manage and troubleshoot, with any issue potentially taking a long time to be fixed. This network cannot be considered a successful scalable design either.
How to achieve network design?
To achieve a network design that delivers value to the business and aligns with its goals and directions, network designers must follow a structured approach. This approach must start from the top level, focusing on business needs, drivers, and directions, to generate a business-driven design. In addition, with the top-down approach, network designers and architects can always produce business-driven network architecture that facilitates, at later stages, the selection of the desired hardware platforms and technol-ogy features and protocols to deploy the intended design. This makes the network design more responsive to any new business or technology requirements. Furthermore, considering the different design principles discussed in this chapter and considering the different requirements (business, functional, and mission-critical applications) can help network designers to plan and make the right design choices that ultimately will make the network be seen as a “business enabler.”
What is modular design?
Modular design is commonly used in software development , where an application can be built from multiple blocks of codes that collectively integrate to form the desired application. These “building blocks” of modular structure enhance and simplify the overall application architecture. For example, if an issue exists in one block or module of that software, it can easily be isolated from the other modules and fixed separately without impacting other parts. Furthermore, from the perspective of ongoing enhance-ments, it is easier to add additional modules or blocks to this structure if new features are required. This makes the overall application architecture more structured and manageable.
What is network design?
Network design can be defined as the philosophy that drives how various components, protocols, and technologies should be integrated and deployed based on certain approach-es and principles to construct a cohesive network infrastructure environment that can facili-tate the achievement of tactical or strategic business goals. Previous sections in this chapter described the end-to-end process of a network design (PPDIOO) and the approaches that you can use to tackle different network designs (top down and bottom up).
What are constraints in network design?
Constraints are factors or decisions already in place and cannot be changed and often lead to a direct or indirect impact on the overall design and its functional requirements. In reality, various design constraints affect network design. The following are the most common constraints that network designers must consider:
How to develop a successful network design?
To develop a successful network design, a proper planning approach is required to build a coherent strategy for the overall design. Network designers can follow two common planning approaches to develop business-driven network designs and facilitate the design decisions:
Why is a reliable network important?
In today’s modern converged net-works, maintaining a highly reliable network is extremely important because modern businesses rely heavily on IT services to achieve their business goals. For these businesses (especially service providers and modern financial institutions), it can be even more critical that their network is considered as a revenue-generating entity. For example, a five-minute network outage that might affect x number of customers can cost the busi-ness hundreds of thousands of dollars. Therefore, having a highly reliable and available network architecture that can survive during any network component failure without any operator intervention (also known as resiliency ) is a key design principle. It is considered a top priority of most of today’s modern businesses. For the network to achieve the desired level of resiliency, a redundant component must exist to take over the role of the failed component following a failure event.
