With the CDN World Summit coming up this week in London (Oct 26-28), it seems a good time to describe something that’s been a working passion of mine: CDNI, where the “I” stands for “Interconnect.”
What’s CDNI? It’s a new working group within the Internet Engineering Task Force (IETF), co-chaired by myself and my colleague Rich Woundy, Senior VP/Software and Applications for Comcast. The working group mission is to develop standards for the interconnection of CDNs run by different operators, so they can inter-operate and collectively provide a multi-footprint CDN — thereby pooling resources that are owned and operated by multiple operators.
It’s all about how to link up the world’s CDNs, so that they can exchange information and work collectively. Just like the Internet was about linking up the world’s IP networks.
In this brief video discussion, Cisco’s Director of Video Solutions Marketing, Murali Nemani talks candidly about “what’s in it for cable” to deliver a suite of IP video services. In his view, it’s a three-step process that’s already beginning.
First, sending video services over bonded DOCSIS channels means pursuing the only path to those 15 billion video-hungry, IP-enabled end points which analysts predict will be present at the end points of the broadband network within 5 years. Whether “managed” (by the cable operator, such as cable modems and set-tops) or “unmanaged” (purchased by consumers), those IP end points will be seeking video over broadband.
Second, the continued attention and investment in DOCSIS 3.0 rollouts will help fend off competitive broadband “speed wars” while laying the foundation for video delivered over IP. Cable operators have the plant capacity, spectrum, and scale to reach an unprecedented footprint of IP end devices.
Lastly, cable’s continued work on the “video back end,” from content delivery networks (CDNs) to set-tops and next-generation gateways, will help the industry permeate the IP video marketplace and drive adoption across the U.S.
