A subport represents a predefined group of users. + +2. A pipe represents an individual user/subscriber. + +3. A traffic class is the representation of a different traffic type + with a specific loss rate, delay and jitter requirements; + such as data voice, video or data transfers. + +4. A queue hosts packets from one or multiple connections of the same type + belonging to the same user. + +The detailed description of the application items and mode can be found in +https://doc.dpdk.org/guides/sample_app_ug/qos_scheduler.html + +Prerequisites +============= +The DUT must have four 10G Ethernet ports connected to four ports on +Tester that are controlled by the Scapy packet generator:: + + dut_port_0 <---> tester_port_0 + dut_port_1 <---> tester_port_1 + dut_port_2 <---> tester_port_2 + dut_port_3 <---> tester_port_3 + +Or use IXIA as packet generator. + +Assume four DUT 10G Ethernet ports' pci device id is as the following:: + + dut_port_0 : "0000:05:00.0" + dut_port_1 : "0000:05:00.1" + dut_port_2 : "0000:05:00.2" + dut_port_3 : "0000:05:00.3" + +1. Compile DPDK and sample with defining:: + + CONFIG_RTE_SCHED_COLLECT_STATS=y + +2. Bind four ports to dpdk igb_uio driver:: + + ./usertools/dpdk-devbind.py -b igb_uio 05:00.0 05:00.1 05:00:2 05:00.3 + +Test Case: single packet flow +============================= +1. This example uses a single packet flow configuration + which creates one RX thread on lcore 5 reading from port 3 + and a worker thread on lcore 7 writing to port 2:: + + ./qos_sched -l 1,5,7 -n 4 -- --pfc "3,2,5,7" --cfg ../profile.cfg + +2. Set flows with different vlan ID, which represent different pipes. + Each Rx flow is shaping to 1/4096 of Tx flow. + Set flows with different Destination IP address (0.0.X.0), + such as 100.0.1.0-100.0.4.0, which represent different tc. + Check the Rx/Tx Bps too. + +Test Case: two packet flows +=========================== +1. This example with two packet flow configurations using different ports + but sharing the same core for QoS scheduler is given below:: + + ./qos_sched -l 1,2,6,7 -n 4 -- --pfc "3,2,2,6,7" --pfc "1,0,2,6,7" --cfg ../profile.cfg + +2. Set flows to port 3 and port 1 with different vlan ID. + Each Rx flow is shaping to 1/4096 of Tx flow. + Set flows with different Destination IP address (0.0.X.0), + such as 100.0.1.0-100.0.4.0, which represent different tc. + Check the Rx/Tx Bps too. + +Note that independent cores for the packet flow configurations +for each of the RX, WT and TX thread are also supported, +providing flexibility to balance the work. +The EAL coremask/corelist is constrained to contain +the default mastercore 1 and the RX, WT and TX cores only. -- 2.5.0
