Chapter 6. Network Availability Design Strategies

This chapter provides a survey of availability strategies from a networking perspective. Keep in mind the required degree of availability during the network design process. Availability has always been an important design goal for network architectures. As enterprise customers increasingly deploy mission-critical Web-based services, they require a deeper understanding of designing optimal network availability solutions.

There are several approaches to implementing high-availability network solutions. This chapter provides a high-level survey of possible approaches to increasing network availability and shows possible deployments using actual implemented examples.
