Disruptive innovation in networking is not going to come from “”yet another”” BGP stack or by adding more APIs to monolithic network operating systems. To date, the NOS architecture has been stretched beyond its original intent in an attempt to leverage modern orchestration and automation toolchains. As we move into the Cloud Native era, we need to evolve the core architecture of the NOS to embrace technologies that define Cloud Native – microservices, serviceability, and resiliency.
Using my years of experience running hyperscale environments at Apple, I can clearly see that networking cannot move forwarding using the approaches available today. Although disaggregation has facilitated networks to be more, open – it has stopped short of modernizing the NOS, thus not addressing the truly difficult problems that operators face in regards to automation, security and time to service.
The talk starts by sharing my firsthand experience with the challenges of running networks at scale with legacy approaches, including disaggregation. It finishes with an example of an alternative architectural model that looks to elevate the NOS towards the Cloud Native approach.
