Impressive, Alibaba used something like that with RDMA to hook up remote storage/tls termination/transcoding.<p>The entirety of control plane is done in http apis that basically ssh into switches and opens L2 route from the client to RDMA box.<p>Then the userspace lib calls the control server to get address and settings for that RDMA box.<p>Every other interaction is than handled by userspace libraries that don't expose RDMA.
