New framework needed for open source switching
According to Cardenas, the development of open source switching has proved challenging given Broadcom's dominance in the market. Obtaining the vendor's software development kit (SDK) isn't necessarily easy nor does receipt of it guarantee that a vendor's subsequent product will be as full-featured as it should be, Cardenas said. He suggests that to make open source switching a reality, developers and competitors should escalate the pressure. Cardenas cites Mellanox's Linux kernel derived project, switchdev, as an example of what can be done. Bottom line, writes Cardenas: "Without an open source framework to drive merchant silicon, we won’t truly have an open source NOS."
