For the past 10 years, we’ve been hearing about IPv4 address space depletion and I always took it with a slight shrug, believing that there would be ways to manage a punctual migration to IPv6. I was of the opinion that just like the Netware server forgotten in my basement, IPv4 would be with us for the next 20 years (at least!) as the world pursued its migration to IPv6.
But recently I’ve had a change of heart. Carriers have had to deal with a very tight supply of IPv4 space, and some years ago, started to re-use internal (RFC1918) IP space for network element addressing. We’re faced with such a large explosion of mobile device and IP-aware machines that it has become imperative to use Carrier Grade Network Address Translation (CG-NAT) to stave off the lack of IP address resources.
Now, NAT and CG-NAT certainly aren’t that new, but recent standards such as RFC6598 enable service providers to deploy address translation (NAT44, NAT444) within a better established framework. Read the rest of this entry »

Networks are teeming with video and audio streaming – our newly released Global Internet Phenomena Report revealed that streaming comprises more than half of mobile data traffic in North America, from frontrunner content providers such as YouTube, Pandora and Netflix, to a wide range of others. The massive growth of video drives operators to seek methods to optimize this traffic, but buyers beware! Not all video optimization techniques are able to achieve the network savings that operators are seeking and the quality of experience that subscribers are demanding.
