Extend high CPS flow table management from DPU to host CPU

A system comprising:

• a host including a policy agent executing on the host and a data plane development kit (DPDK) interface;
• and
• a data processing unit (DPU) to transmit packets to the host, wherein the DPDK interface of the host performs operations including:
• evaluating the transmitted packets at the host;
• generating packet evaluation results;
• selecting, with the policy agent executing on the host, a data processing library based on the packet evaluation results;
• and
• transmitting a control packet containing the selected data processing library from the policy agent of the host to the DPU,
• wherein the DPU is further configured to receive the transmitted control packet and execute a software proxy on a plurality of cores to program datapath tables based on the selected data processing library and wherein write access to the datapath tables is restricted to the plurality of cores.

A non-transitory computer-readable storage medium storing instructions, which when executed on one or more processing devices, uses a data plane development kit (DPDK) interface running on a host to perform operations including:

• receiving packets from a data processing unit (DPU);
• evaluating the received packets at the host;
• generating packet evaluation results;
• selecting, with a policy agent executing on the host, a data processing library based on the generated packet evaluation results;
• and
• transmitting, to the DPU, a control packet comprising the selected data processing library from the policy agent of the host.
