SDN Blog

It is well known that bare metal switches and SDN software that powers them have been successfully deployed in hyperscale data centers (e.g. in Google, Amazon) for many years.  These modern network designs – with HW/SW disaggregation and no vendor lock-in – have proven beneficial in terms of unprecedented application agility, massive operational simplification and dramatic cost savings. &...

This week’s big networking news is that Facebook announced that they have built their own switch (codenamed “Wedge”) and the corresponding networking software on top (“FBoss”).  While the specific technical details are still coming out, I’m more interested in why they did it.  Facebook is an advertising company on steroids, not a networking vendor.  They are not going to...

Achieving DC-Class Resiliency and “Headless” RecoveryIn the second part of the technical blog series, I talk about how forwarding state in modern OpenFlow is communicated from SDN controllers down to switches.  While this level of detail is well beyond what a typical administrator needs to understand about networking products, it is key to SDN’s scalability and reliability.  More s...

Unlocking Hyperscale with Multiple TablesEven after four years of work from the Open Networking Foundation (ONF), three substantial updates to the specification, and countless training sessions, there still exists significant confusion about the OpenFlow protocol and SDN -- particularly about their performance and scale. Fortunately, as more OpenFlow-based commercial products ship and customers ex... Read more
