Supporting IPv6 on a Linux Server Node
As part of our activities in the Open Architecture Research at Ericsson Research Canada, we are conducting several IPv6-related projects, such as supporting IPv6 on our telecom-grade server nodes, porting application servers to work with IPv6 and establishing research projects in different IPv6 areas.
One of the interesting activities we carried out was to experiment with the Linux IPv6 implementations currently available and present recommendations to decide which implementation to adopt for our Linux processors. The recommendations were based on IPv6-implementation characteristics, such as its development speed, its compliance to the standards and its performance vs. other implementations. The results were presented during the Linux Symposium in Ottawa, Canada, June 26-29 (www.linuxsymposium.org/2002/view_txt.php?text=abstract&talk=93).
For 2002, we continue to support IPv6 on our Linux clusters. Our current efforts are in the direction of supporting IPv6 on the SIP and SCTP implementations for Linux, as well as building an IPv6 benchmarking environment capable of testing the performance and scalability of platforms and applications running over IPv6.
In closing, it's important to know that one of the key advantages of IPv6 is addresses. Any individual can receive as many addresses as the current IPv4 address space. This empowers users with complete freedom to deploy servers and services without having to take care of NAT problems and limited address space. Welcome to the freedom of deploying services on the Internet!

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
