Status of IPv6 John Sweeting Time Warner Cable Oct 5, 2011 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 • http://www.timewarnercable.com/Corporate/support/IPv6_volunteer form.html 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 o o o Launched in late 2008 Lee Howard heads up the program Over 20 Project Managers involved 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 o o o 3 year process OSS/BSS systems DHCP, TFTP, DNS, several internal systems 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 Thank You !
