Facebook Shares Open Networking Switch Design, Part of its Next Gen Networking

Facebook’s enormous scale comes with enormous technological challenges, which go beyond conventional available solutions. For example, Facebook decided to abandon Microsoft’s Bing search engine and instead develop its own revamped search capabilities. Another important area is Facebook’s massive networking needs, which called for a whole new paradigm, code named data center fabric.

The next step in Facebook’s next-gen networking architecture is “6-pack” – a new open and modular switch announced just a few days ago. Interesting to note that Facebook chose to announce the new switch the same day Cisco reported its earnings. This is more than a hint at the Networking equipment giant, representing the “traditional networking”. As Facebook says in its announcement, it started the quest for next-gen networking due to

the limits of traditional networking technologies, which tend to be too closed, too monolithic, and too iterative for the scale at which we operate and the pace at which we move.

The new “6-pack” is a modular high volume switch built on merchant silicon based hardware. It enables you to build any size switch using a simple set of common building blocks. The design uses Software Defined Networking (SDN) hybrid approach: While classic SDN separates control plane from forwarding plane and centralizes control decisions, in Facebook’s hybrid architecture each switching element contains a full local control plane on a microserver that communicates with a centralized controller.

Facebook made the design of “6-pack” open as part of the Open Compute Project, together with all the other components of its data center fabric. This is certainly not good news for Cisco and the other vendors, but great news for the community. You can find the full technical design details in Facebook’s post.

Faceook is not the only one in the front line of scaling challenges. The open cloud community OpenStack, as well as the leading public cloud vendors Google and Amazon also shared networking strategies to meet the new challenges coming with the new workloads in modern cloud computing environment.

Cloud and Big Data innovations were born out of necessity in IT, driven by companies with the most challenging use cases and backed by open community. The same innovation is now happening with networking, paving the way to simpler, scalable, virtual and programmable networking based on merchant silicon.
