I’ve been posting frequently on networking issues with the key point being the market is on the precipice of a massive change. There is a new model emerging.

· Datacenter Networks are in my way

· Networking: The Last Bastion of Mainframe Computing

We now have merchant silicon providers for the core Application Specific Integrated Circuits (ASICs) that form the core network switches and routers including Broadcom, Fulcrum (recently purchased by Intel), Marvell, Dune (purchased by Broadcom). We have many competing offerings for the control processor that supports the protocol stack including Freescale, Arm, and Intel. The ASIC providers build reference designs that get improved by many competing switch hardware providers including Dell, NEC, Quanta, Celestica, DNI, and many others. We have competition at all layers below the protocol stack. What’s needed is an open, broadly used, broadly invested networking stack. Credible options are out there with Quagga perhaps being the strongest contender thus far. Xorp is another that has many users. But, there still isn’t a protocol stack with the broad use and critical mass that has emerged in the server world with the wide variety of Linux distributions available.

Two recent new addition to the community are 1) the Open Networking Foundation, and 2) the Open Source Routing Forum. More on each:

Open Networking Foundation:

Founded in 2011 by Deutsche Telekom, Facebook, Google, Microsoft, Verizon, and Yahoo!, the Open Networking Foundation (ONF) is a nonprofit organization whose goal is to rethink networking and quickly and collaboratively bring to market standards and solutions. ONF will accelerate the delivery and use of Software-Defined Networking (SDN) standards and foster a vibrant market of products, services, applications, customers, and users.

Open Source Routing Forum

OSR will establish a “platform” supporting committers and communities behind the open source routing protocols to help the release of a mainstream, and stable code base, beginning with Quagga, most popular routing code base. This “platform” will provide capabilities such as regression testing, performance/scale testing, bug analysis, and more. With a stable qualified routing code base and 24×7 support, service providers, academia, startup equipment vendors, and independent developers can accelerate existing projects like ALTO, Openflow, and software defined networks, and germinate new projects in service providers at a lower cost.

Want to be part of re-engineering datacenter networks at Amazon?

I need more help on a project I’m driving at Amazon where we continue to make big changes in our datacenter network to improve customer experience and drive down costs while, at the same time, deploying more gear into production each day than all of Amazon.com used back in 2000. It’s an exciting time and we have big changes happening in networking. If you enjoy and have experience in operating systems, networking protocol stacks, or embedded systems and you would like to work on one of the biggest networks in the world, send me your resume (james@amazon.com).
