Physical Network Implementations
The next step involves constructing a real network based on the logical network architecture. You can use several approaches to realize the network that functionally satisfies the logical architectural requirements.
The multi-tier data center is vendor independent, and you can use the network equipment that best suits your environment. We briefly describe the original multi-tier data center implementation (secure multi-tier architectures), then we describe the multiswitch approach, and finally we describe the collapsed approach.
Secure Multi-Tier
FIGURE 7-13 shows the overall structure of a classic multi-tier design.

The advantages of this approach are simplicity and security. Clearly ...
