Large-Scale IP Network Solutions (CCIE Professional Development)

Summary

Network design involves the art and science of meeting requirements while dealing with economic, technological, physical, and political constraints. Scalability and extensibility are the hallmarks of a successful large-scale network design, and are encouraged through layering, modularization, and hierarchy. Randomization, soft state, dampening, separation of the control plane, regionalization, and optimizing the common case are also important considerations for routing protocols and the overall routing topology.

Although requirement analysis is an important aspect of design, it should be viewed as an ongoing task and should be ratified by the collection of traffic statistics that describe actual network usage.
