I wanted to thank the folks here for pointing out a few issues that we (the authors of the books) hadn't noticed, particular around the meaning of "A Systems Approach". Our definition of the Systems Approach is now on https://www.systemsapproach.org/ https://www.systemsapproach.org/ - The "Systems Approach" refers to the field of design and implementation of computer systems. The term is used commonly by computer science researchers and practitioners who study the issues that arise when building complex computing systems such as operating systems, networks, distributed applications, etc. The key to the systems approach is a "big picture" view – you need to look at how the components of a system interact with each other to achieve an overall result, rather than simply optimizing each component. In the networking context, that often means going beyond the traditional layered view to see how an issue is best tackled in a way that might touch several layers. The Systems Approach has a strong focus on real-world implementation, with the Internet being the obvious example of a widely-deployed, complex networking system.
