TRANSCRIPT
Outline
• About Time Warner Cable • Current Status • How we got here • Left to do • Future Networking Thoughts
Time Warner Cable • Second largest MSO (Multi Systems
Operator) in the United States • Providing high definition television,
Enhanced TV features, high-speed data and Digital Phone services to over 14 million customers
• Major service areas are New York City, Los Angeles, Texas, Upstate New York, Ohio, the Carolinas and Hawaii
Current Status • National Backbone
o Dual Stack o Supports IPv6 Services o IPv6 Peering enabled with several Peers
• Regional Backbones o Dual Stack o Supports IPv6 Services o Connects to National Backbone
Current Status • Access Networks
o IPv6 enabled o Commercial Dedicated IPv6 Internet Access o Residential cable modems in trial
• Data Centers o IPv6 Network connectivity o Supports some IPv6 Services o Connects to Regional backbone
Current Status • Systems
o 40 plus unique systems o Over 90% IPv6 enabled o Minor bugs and some interoperability issues
• Services o Commercial DIA launched September 2011 o Residential trials gearing up

o Peering
How We Got Here • Lots of hard work
o Vendor Management was tough o Internal planning and coordination meetings (lots
of them)
• Internal IPv6 Program o Launched in late 2008 o Lee Howard heads up the program o Over 20 Project Managers involved o Lots of internal education required
How We Got Here • Network Upgrade
o Coordinated effort of Architecture, Engineering, Quality Assurance and Operations
o Four phase roll out • National Backbone to Regional Networks • Data Centers • Regional Networks to Metros • Access networks – CMTS’s
• Systems Upgrade o 3 year process o OSS/BSS systems o DHCP, TFTP, DNS, several internal systems o Again lots of hard work and coordination
Left to Do • Major Issues
o Home Networking • Routers, Game Systems, Home Gateways • Cable Modems and E-MTA’s • Computer systems
o Vendor Management • Mainly CPE Vendors • Edge and Access Vendors
o Replacement of incompatible hardware
Future Networking • Home Networking
o Increase in the number of isolated networks in the home (think more 802.11 SSIDs)
o Home security and automation o Multi-router including support for arbitrary
topology o Multi-connected (e.g. separate wireless and wire
line provider) o Smart Energy Applications and Appliances
Future Networking • IPv6 Deployment in the home will bring
about the following: o Massive public address space (capable of
supporting every device with a unique IP) o Multiple routed segments – move away from flat
VLAN-type model to multiple routed interfaces presumably separated by firewall functionality
o Exponential increase in complexity will have to be balanced with auto-configuration of the home network
