The Need for IPv6
 Next Generation Satellite Platform


Satellite Modems supported dual stack for the Data
plane
Control/Mgmt plane was IPv6
 IP Exhaustion



Mgmt /Control Plane Yes – running out of RFC1918
Don’t have any Network Layer abstraction yet (MPLS)
Data plane – not really as we have IPv4 NAT –
however, IPv6 gives a direct shot to the internet!
Options
 We went straight to Dual stack!

No Tunneling and no transition strategies
 Life was easy for us because this was a greenfield
deployment and the Modems supported IPv6
 Got ARIN assignment: 2600:E000::/28
 Got Transit from our existing providers
IPv6 Advertisements
Level Of Difficulty
 Access
As mentioned the Modems
supported IPv6

 Core

Our Core had the latest routers with the latest images
which also supported IPv6
 Edge

Getting IPv6 transits was a piece of cake ( Our first
attempt was with GTT )
Impact
 Subscriber Experience:


No problems experienced this was completely
transparent to the customers
Win 7, Vista etc all supported dual stack
 Operations

A new set of skills was required and this was a
challenge
 Engineering

IPv6 is now always the first thing ( instead of the last
thing )
Design Decisions
 IPv4 design should not depend on IPv6 Design and




vice versa.
Complete separation between families ( peraddress BGP sessions )
Multi-topology ISIS
Stay far away from transition strategies
Host effectively gets a /64
Traffic Trends
 Different OS’ and applications will prefer different
means of accessing the internet.
 Certain Apple Products seem to prefer IPv6 vs IPv4
NAT
 NetFlix and Youtube tend to use IPv6 ( happy
eyeballs )
 If there is a AAAA record – IPv6 appears to be
chosen!
Traffic Trends
 Traffic Split( new platform only ) – IPv6/IPv4



Real Time Entertainment: 60/40
Social Networking: 70/30
Web Browsing: 40/60
The Future
 Our Network Element Traffic Graphs don’t classify
traffic by Type ( IPv4 and IPv6 ). We use Netflow (
but then that’s based on a sampling rate )
 We have an Analytics platform on the Edge which
shows IPv6 stats but would be beneficial to have
more granular visibility further in the Core and
Access
 Expand IPv6 to other brownfield deployments
 Press Vendors for Dual stack support
Some Resources
 Hurricane Electric’s “IPv6 Certification” program, which I strongly
recommend for getting one’s hands dirty
