A BELL LABS STUDY ON RISING VIDEO DEMAND AND ITS IMPACT ON BROADBAND IP NETWORKSAs consumers demand ever more video and video consumption methods, the broadband IP networks used by many service providers to offer residential services will be overwhelmed by the sheer volume of data. The problem will be most acute at the IP edge of a triple-play provider’s network, where video traffic will grow 2.5 times faster than traffic on subscriber links. To thrive in this new era of high bandwidth services, service providers will need to delight their customers with compelling new video on demand (VoD) services while keeping unicast video transport costs in check and controlling the bandwidth consumed by over-the-top (OTT) video.To accomplish their goals, providers need to move away from broadband architectures based on legacy Broadband Network Gateway/Broadband Remote Access Server (BNG/BRAS) routers and adopt a distributed network architecture based on enhanced, terabit-speed BNGs and content delivery network (CDN) caches.This document provides a detailed forecast of video consumption to 2020, determines the impact of video growth on IP service networks, and outlines strategies for rising above these challenges. A detailed Bell Labs case study quantifies the total cost of ownership (TCO) savings of moving from a centralized to a distributed IP edge with CDN caching.
