The paper shows how large carriers use IP edge routers:
- TELUS, Portugal Telecom, and Belgacom reduced opex by leveraging a common IP platform to deliver a combination of residential, business, and mobile services
- British Telecom and Portugal Telecom solved the video onslaught with caching/content delivery networks (CDNs), delivery of high quality unicast video, and per-flow QoS
- Portugal Telecom added multiscreen and network intelligence for applications
- Portugal Telecom and Belgacom provide high performance, secure, flexible L2/L3 VPNs, and use them for access to cloud services
- Operators now have the tools to increase revenue with CDN services, a broadband “turbo” button, and new service bundles that are impossible with separate service networks
