Hi,

cores and ports and queues can be mapped just about any way that your application
wants. The only real restriction is that two cores cannot poll the same queue
on the same port at the same time.
You can set up your app to have each port polled by a single core, or to have
all ports polled by one core, or to have one port polled by multiple cores (using
different queues).

Hi,

cores and ports and queues can be mapped just about any way that your application wants. The only real restriction is that two cores cannot poll the same queue on the same port at the same time.

What application are you using? DPDK is primarily a set of libraries, and
contains some apps purely as examples or for testing.

I am using OVDK (dpdk openvswitch ), where I need to enhance the packet processing speed on DPDK data path by modifying lcore-- port-- queue mapping .
