摘要： Methods and apparatus for smart switch centered next generation cloud infrastructure architectures. Smart server switches are implemented in place of Top of Rack (ToR) switches and other switches in cloud infrastructure that include programmable switch chips (e.g., P4 switch chips) that are programmed via data plane runtime code executing on the switch chips to implement data plane operations in hardware in the switches. Meanwhile, control plane operations are implemented in the server switches via software executing on one or more CPUs or are implemented via servers that are coupled to the server switches. The data plane runtime code is used to forward data traffic and storage traffic in hardware via the programmable switch chips in a manner that offloads forwarding to hardware in virtualized cloud environments.
