6RD: offer an IPv6 Service over an IPv4 Backbone

Friday, January 13th, 2012

6RD (RFC5969)

In 2007, Remi Despres, already famous for having designed Transpac–an X25 Network in the 80s, had the idea to customize 6to4 to make a protocol that a Service Provider could use to deploy an IPv6 Service over an IPv4 Backbone.

For a full overview of all the principle Transition Protocols, please refer to this blog:

The first popular automatic tunnels were 6to4. 6to4 solved two problems, IPv6 addressing and automatic destination tunnel configuration. 6to4, Connection of IPv6 Domains via IPv4 Clouds, RFC 3056 was published in 2001. It was one of the first transitions to IPv6 protocols after the static tunnels and dual-stack.
It provided the reserved IPv6 prefix, 2002::/16.

The labs have been redesigned completely to support the SP environment and will follow the order of the transition phase for a Service Provider which is planning a transition to IPv6.

The Labs description is provided below…

Why it’s the right time to start working in 802.11 wireless: new protocols are coming

Thursday, November 10th, 2011

So you thought that 802.11n was the ultimate protocol, allowing 300 Mbps, maybe up to 450 Mbps? If you are not working in wireless yet, now is the right time to think about switching career, and starting to get a few certifications in the 802.11 wireless field: new protocols are coming that will change the deal for a long time, and make 802.11 THE protocol you want to be expert on. So get some Cisco wireless training and prepare for the storm to come: Read the rest of this entry »

A+P An Interesting Alternative To Large Scale NAT (LSN) or Carrier Grade NAT (CGN)

Monday, October 17th, 2011

1. Introduction

Since most IPv4 addresses are taken (and many people have not yet started their transition process to IPv6), we need to make sure that we have all the tools available to make the most of the remaining addresses without breaking the Internet even more than we did with NAT.

Carrier Grade NAT (CGN) or Large Scale NAT (LSN) proposes to run NAT at the Service Provider rather than, or in addition to, the Customer Premises Equipment (CPE).
