Hi Mahdi, Looks like the DPDK's rte_distributor is the right tool for your task. Please have a look at: http://dpdk.org/doc/guides/prog_guide/packet_distrib_lib.html
There is also the Distributor Sample Application in DPDK: http://dpdk.org/doc/guides/sample_app_ug/dist_app.html Please do not cross-post to dev@ mailing list.
