-Test Case: single packet flow
-=============================
+Test Case: 1 pipe, 8 TCs
+========================
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.

+ Frame size=70bytes.
+ Send rate is 100% linerate.
+ The pipe’s rate is limited to 1/4096 linerate.
+ So priority guarantees tc0 rate, while tc1 has few packet forwarded.

+Test Case: qos_sched of two ports
+=================================
+1. This example with two packet flows configuration 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.
+ ./qos_sched -l 1,2,6,7 -n 4 -- --pfc "0,1,2,6,7" --pfc "1,0,2,6,7" --cfg ../profile.cfg
+
+2. The traffic manage setting is configured in profile.cfg.
+ Set flows with QinQ inner vlan ID=random, which represents pipe 0-4095.
+ Set IP dst address from 10.0.0.0~10.0.0.15, which enter queue0~queue15,
+ mapping TC0~TC12.
+ Frame size=70bytes.
+ Send rate is 100% linerate, which is 13.89Mpps.
+ Received rate from port 0 and port 1 are both 8.10Mpps.
+ No packets are dropped on two ports.
+ You can check the pipe0~pipe4095 of port0 and port1 stats::
+
+ qos_sched> stats port 0 subport 0 pipe 4095

+
+ It might be the case that packets are dropped due to less space in mempool.
+ In this experiment, we are stressing the system with more packets
+ to see how much scheduler can process.
Note that independent cores for the packet flow configurations
for each of the RX, WT and TX thread are also supported,
