A Simple Framework for IP Network Design

A Simple Framework for IP Network Design Jeff Loughridge Principal Consultant Brooks Consulting LLC

Industry Trends • Per-Mb prices in perpetual downfall • Utilization constantly increasing • New services emerging

The two fundamental components of IP networks are routers and fiber.

An IP network core’s primary function is to move bits as inexpensively as possible.

The Ideal All-IP Environment • Maintains end-to-end principle • Intelligence in the end points; limited state maintained in the core • Clear demarcation between IP network performance/capabilities and applications that rely on network for bit carriage • Limited number of devices in the data delivery path

Business Requirements for IP Networks • Simple to add new services • Generate new revenue without major overhauls to processes and systems • Easily adaptable to technology change • Full transparency – costs, metrics, accountability • Seamless access to the network

Simplicity and Cash Flow • When a new device or system is added to the infrastructure, is value added commensurate with the investment? • What is the effect on the cost structure? • Minimizing cost-per-bit

Conclusion • Design simple IP networks- you and your customers will mutually benefit • Ask questions – – Why are we adding this complexity to the network? – Are we pouring money into network elements not designed for IP? – What is the effect on the cost per bit
