2、SnapRoute  //??

Founded by engineers who created and reliably operated some of the largest data center networks on the planet by adopting open networking principles, SnapRoute is dedicated to bringing simplicity, reliability, and white-box economics to data center networks everywhere. SnapRoute’s FlexSwitch software runs on industry standard white-box switches, providing all management and networking functionality through an innovative architecture that simplifies the networking stack and dramatically reduces the code bloat typical of incumbent products. SnapRoute makes it easy to automate network provisioning while giving unprecedented visibility into how the network is running.  SnapRoute is backed by Norwest Venture Partners, Lightspeed Venture Partners, AT&T, and Microsoft.  

3、FBOSS(facebook) //barefoot

github：https://github.com/facebook/fboss

FBOSS is Facebook's software stack for controlling and managing network switches.

4、SONiC(azure) //trident, barefoot, caviun, centec

github: https://github.com/Azure/SONiC

SONiC is an open source project for network routers and switches.

 5、Switch Light（bigswitch) //

Switch Light™ is a Linux-based, thin switching software solution, providing consistent data plane programming abstractions across merchant silicon-based physical switches (white-box or brite-box) and hypervisor vSwitches.

Switch Light is a key enabling technology for Big Switch Networks’ centralized SDN applications, and comes in two flavors:

• Switch Light OS: a complete SDN operating system based on Open Network Linux (ONL), an open source effort within the Open Compute Project.
• Switch Light VX: a user space software agent for KVM-based virtual switches that adds advanced functionality and improved performance on top of the Open vSwitch kernel.

6、Cumulus linux //trident, Mellanox Spectrum, 

The world’s most flexible open network operating system for bare metal switches。

>> ONL（open network linux）

源代码：https://github.com/OpenComputeProject/OpenNetworkLinux

Open Network Linux is a Linux distribution for "bare metal" switches, that is, network forwarding devices built from commodity components. ONL uses ONIE to install onto on-board flash memory. Open Network Linux is a part of the Open Compute Project and is a component in a growing collection of open source and commercial projects.
