• Export virtual interface drop and error counters as metrics. 3.0. DPDK Keep Alive Core Status is exposed When a DPDK primary process starts it configures the system, writing a configuration file.
  • 1) QoS support for DPDK vRouter: TF vRouter supports QoS marking and enforcement. The marking part is done leveraging Linux kernel support and enforcement in the physical interface is done using a utility called ‘qosmap’ which configures the NIC queues with the desired scheduling and priority. However, in DPDK, this support is not there.

  • Command line DPDK configuration controls a number of parameters, including device whitelisting, the number of CPUs available for launching dpdk-eal-controlled threads, the number of I/O buffers, and the process affinity mask. In addition, the DPDK configuration function attempts to support all of the DPDK EAL configuration parameters.
  • After a data packet is received from an entrance network card port by a DPDK receiving-transmitting packet, a DPDK data packet mbuf is copied to a packets buffer with a user-defined format and then the mbuf is returned to the DPDK; when the packets buffer is going to exceed the internal memory space size, the packets buffer is placed into a ...
