Network Blueprint for Capacity Planning

Figure 14-1 serves as the basis for this case study. It represents the different components of a service provider network from a high-level perspective:

• Provider edge (PE) routers connected to the core network

• Customer edge (CE) routers connected to the customers

• Multiple points of presence (PoP) composed of PE and CE routers

• Server farms or data centers

• A core network connecting all the pieces to an intranet

• Different BGP routers (numbered from 1 to 4) for the Internet connections via different providers and the BGP Autonomous Systems (AS) (displayed by AS1 through AS5).
