As a network engineer, you're designing a large enterprise network that requires high scalability and optimized performance. You plan to implement a hierarchical design with separate layers for high-speed backbone transport, policy-based routing functions, and direct end-device connectivity. Which network topology architecture best suits this requirement?
Three-tier architecture maps exactly to the requirements described. The core layer forms a high-speed, policy-free backbone that simply switches packets at wire speed between distribution blocks. The distribution layer sits between core and access, enforcing policies, running inter-VLAN routing, and providing aggregation. Finally, the access layer delivers Layer-2/3 connectivity to end devices. By cleanly separating these roles, the design offers superior scalability, simplified troubleshooting, and predictable performance for large enterprise campuses.
