Foundations of Network Architecture – Part 1: Route/Switch

In the previous chapters, we discussed the role a network architect plays within an organization, the skillset needed to fulfill a network architect’s position, along with the concepts and mental framework required to be successful in the role. Now, let’s transition to the technical aspects of the network architect’s role and dive into the foundation of network architecture.

The foundation of network architecture refers to the underlying principles and design concepts that guide the development and organization of computer networks. It encompasses the fundamental components, protocols, and technologies that are used to create and maintain networks to support the following:

• Fault tolerance: The ability of a network to continue operating even when some of its components fail
• Scalability: The ability of a network to grow and adapt to changing demands
• Quality of service (QoS): The...
