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.

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.
