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
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
