White Box Switches: Part Three, OpenSwitch

Wednesday, November 7, 2018 1:57:47 PM Asia/Taipei

OPS And OPX, or a Bit of History

At first, OpenSwitch project and openswitch.net were governed by HP as they tried to ride the "open networking" wave. An open community, a lot of talk-based supports from several vendors, all as usual.

Efforts were made to create a set of protocols and an SAI connector to make adoption of new silicon easier.

After about 8 months, the project was handed to the Linux Foundation. A proper excuse was made - HPE said the move was a way to show the community that this wouldn’t be an effort controlled by one vendor.

White Box Switches: Part Two, ICOS

Saturday, October 27, 2018 12:16:47 PM Asia/Taipei

A common description

It’s easy to find pieces like these:

  • Web-scale NOS with traditional L2/L3 functions and management, with an API structure for third-party apps and integration with provisioning and orchestration systems.

  • Broadcom ICOS/FASTPATH is an off-the-shelf (Linux based) network operating system (NOS), providing traditional L2 and L3 functions and management, with an API-structure for value-added applications and integration with provisioning and orchestration systems.

  • ICOS is a robust, programmable full featured and most widely deployed networking operating system for enterprise and data center networking. Its built-in arbitration between conventional and SDN flows allowing customers seamless integration to Next-Gen Open programmable networks.

  • FASTPATH production-ready networking software helps manufacturers achieve record-setting time-to-market performance for introducing new Ethernet products. In part, this advantage comes from the extensive feature set and integration capabilities that give Broadcom’s software unprecedented application flexibility.

A general praise to its wholesome, next-gen design, apps and APIs. Typical marketing stuff that gives no real understanding of the product.
