End of the World Revisited: No More IPs!

We’ve posted this before, but in honor of the end of the Mayan calendar and the destruction of the world which was forecast for today we’re posting it again. In our mind, not having any more IP addresses would be a terrible event -  if you’re going to build the Internet of Everything you need a lot of IP addresses! Read More »

Where’s My IPv6 Prefix? Part Deux

December 17, 2012 at 1:12 pm PST

My previous post examined how a regional Provider Independent (PI) prefix is propagated across the Internet.  This post discusses the second aspect of the issue: how does Provider Assigned/Aggregateable (PA) space propagate across the Internet? Read More »

Where’s My IPv6 Prefix? Part One

December 13, 2012 at 5:28 am PST

In a previous blog series about interfacing with your ISP, I mentioned tools that Internet Service Providers (ISPs) have, such as looking glasses and route servers, that can be used to verify their policies.  In this blog post, I want to examine some of those tools, but primarily I want to show how prefixes are propagating across the Internet. 

The question of prefix propagation comes up often when discussing how to develop an IPv6 address plan.  What happens if an organization gets Provider Independent (PI) space from a registry and then tries to advertise that prefix, or a smaller portion of that prefix, in a different region?  Will ISPs in that region filter the non-regional prefix?  Will they let the aggregate pass, but not the more specific prefixes?

Cisco Helps NxtGn and Telarix Deliver IPv6-enabled Video Solution

We’ve talked about how the Internet is forecast to carry a million minutes of video every second in the next few years, and how Cisco’s Elastic Core solution will help the core infrastructure carry that load. But a scalable and flexible core is only one piece of the puzzle that network operators need. Who else is helping to make a video-centric future a reality?

One place to look is a solution that’s been developed by Miami, FL based NxtGn and Virginia-based Telarix. We wrote about NxtGn’s affiliate Next Communications last year, they’ve been successful in wholesale voice communications, in part due to in-house technology paired with an off-the-shelf Cisco ASR 1000 router performing Session Border Control functionality. Packing a softswitch and an SBC that can handle 16K voice or HD video calls in half a rack has enabled them to minimize their costs in a relatively low-margin market. Telarix isn’t as well known outside of the carrier market – they specialize in what is known as “interconnect business optimization” – basically the back-office components to handle billing, auditing, and traffic routing between carriers. While the concept of billing and auditing might make your eyes glaze over, if carriers can’t figure out how to bill for services rendered you can imagine they view that as a really bad thing.
