OF-DPA 2.0 and Tomahawk

Thursday, August 11, 2016 12:05:30 PM Asia/Taipei

There is a word that Aurora 620 and Aurora 720 supports Ubuntu with integrated OF-DPA 2.0

That means an availability of one more NOS option for Tomahawk HW and fully-features OpenFlow 1.3.4 support.

MPLS in all it's glory and several OpenFlow controllers tested.


Sounds interesting for those who want to play with telecom applications.

OpenSwitch NOS for Aurora switches

Tuesday, June 14, 2016 2:57:50 PM Asia/Taipei

An alternative to ICOS is ready – OpenSwitch.

OpenSwitch - an open source, Linux-based network operating system (NOS) designed to power enterprise grade switches from multiple hardware vendors that will enable organizations to rapidly build data center networks that are customized for unique business needs.

 OpenSwitch web interface

Now you can grab a bare metal version of Aurora 720 or Aurora 620 and make it ready for use in your network.

ICOS and Linux shell management.

Wednesday, June 8, 2016 12:43:44 PM Asia/Taipei

More about ICOS here.

DC switch NOS evolution

For many years, switches were black boxes with management through CLI/web or special API from vendors.

Cumulus Linux was the first product that aimed to change the industry and manage a switch like a Linux server with standard Linux management, monitoring, and provisioning tools. However, Cumulus Linux is aimed at the particular market with heavy L3 usage and offers a limited set of network protocols.

What’s going on with traditional CLI-oriented network OS?

They are going to be open too. Let’s take a look at ICOS, a feature-rich package from Broadcom that serves as a foundation for NOS on their ASICs.

Unlike servers, Ethernet switch does not allow simple Linux deployment with an ASIC drivers. Special integration efforts are required for a proper LED indication management, port mapping, power control, etc. Such integration could be implemented in many ways, let’s take a look at them.

100G HW at a cost of 40G.

Thursday, May 5, 2016 6:44:10 PM Asia/Taipei

The price for Aurora 720 100G bare metal switch was aligned to match 40G counterparts - $7000.


Also, 100G optics from Optech was added to our catalog. Quite expensive so far but it’s not in a real volume production yet.

Cost-effective 10G optics from Optech added - high-quality Taiwan-made product.

An open source NOS from Microsoft.

Friday, March 11, 2016 11:26:10 AM Asia/Taipei

called Software for Open Networking in the Cloud or SONiC.


SONiC is a collection of networking software components required to have a fully functional L3 device that can be agnostic of any particular Linux distribution. Today SONiC runs on Debian and available on Github.


No support from Microsoft, they intend to keep SONiC relevant, reliable and stable. The rest depend on a community or your development resources.

A major requirement for the switching silicon - to be SAI-compatible.


A detailed post from Mark Russinovich is here.

Cumulus went to perpetual license model

Tuesday, January 19, 2016 7:50:06 PM Asia/Taipei


    • Align with industry standard – all OS’ sold this way.
    • NOS is integral to the switch – customers expect to own it
    • Reduce procurement/sales barrier – make things frictionless
