Chapter 4. Applying the Principles of Network Design
The elements of network design—hierarchy, redundancy, addressing, and summarization—have been addressed in relative isolation up to this point. The following list groups them together:
Hierarchy— Provides a logical foundation, the "skeleton" on which addresses "hang."
Addressing— Isn't just for finding networks and hosts; it also provides points of summarization.
Summarization— The primary tool used to bound the area affected by network changes.
Stability/Reliability— Provided by bounding the area affected by changes in the network.
Redundancy— Provides alternate routes around single points of failure.
