Today, Internet Protocol (IP) is acknowledged as the optimal network protocol for digital communications. By eliminating network layers, we’ve been able to deploy our Pure IP™ network at significantly lower capital costs and operating expenditures when compared to traditional communication networks. On our Enron Intelligent Network, IP is the convergence layer where the most innovative new applications—like ePowered™ Media Cast—are being developed.

With Enron’s Intelligent Network, Pure IP overcomes these shortcomings of the public Internet for serving rich media content to the desktop:

• Requires multiple hops to reach desired content
• "Best effort" delivery (no guarantee)
• Unpredictable quality of service
• The Internet is extremely oversubscribed

Why Pure IP?

• Deploy a next generation architecture which meets the demand for low-cost, highly reliable IP bandwidth on demand
  
• Deliver high-speed, native IP service only, in a service-optimized network
  
• Avoid applications which require functions not possible in today's IP implementations
  
• Leverage architecture to enable network applications dependent on higher bandwidth
