Traffic scheduling in DPDK

Traffic scheduling in DPDK

[ravulakollu.kumar]

Hello All,

I have an issue in running qos_sched application in DPDK .Could someone tell me how to run the command  and what
each parameter does In the below mentioned text.

Application mandatory parameters:
    --pfc "RX PORT, TX PORT, RX LCORE, WT LCORE" : Packet flow configuration
           multiple pfc can be configured in command line

Thanks,
Uday

RX PORT - Specifies the packets receive port 
TX PORT - Specifies the packets transmit port 
RXCORE - Specifies the  Core used for Packet reception and Classification stage of the QoS application.
WTCORE-  Specifies the  Core used for Packet enqueue/dequeue operation (QoS scheduling)  and subsequently transmitting the packets out.

Multiple pfc  can be specified depending upon the number of instances of qos sched required in application.  For example- in order to run two instance, following can be used-

./build/qos_sched -c 0x7e -n 4 -- --pfc "0,1,2,3,4" --pfc "2,3,5,6" --cfg "profile.cfg"       

First instance of qos sched receives packets from port 0 and transmits its packets through port 1 ,while second qos sched will receives packets from port 2 and transmit through port 3. In case of single qos sched instance, following can be used-

./build/qos_sched -c 0x1e -n 4 -- --pfc "0,1,2,3,4" --cfg "profile.cfg"


Thanks,

Thanks Jasvinder , I am running the below command

./build/qos_sched -c 0xe -n 1  -- --pfc "0,1,3,2" --cfg ./profile.cfg

Bound two 1G physical ports to DPDK , and started running the above command with the default profile mentioned in profile.cfg .
I am using lcore 3 and 2 for RX and TX. It was not successful, getting the below error.

Please, tell me whether I am missing any other configuration.

In default profile.cfg, It is assumed that all the nic ports have 10 Gbps rate. The above error occurs when subport's  tb_rate (10Gbps) is found more than NIC port's capacity (1 Gbps). Therefore, you need to use either 10 Gbps ports in your application or have to amend the profile.cfg to work with 1 Gbps port.  Please refer to  DPDK QoS framework document for more details on various parameters - http://dpdk.org/doc/guides/prog_guide/qos_framework.html

Thanks Jasvinder,

Does this application works on systems with multiple NUMA Nodes ?

After running getting the below error.

        APP: EAL core mask not configured properly, must be 16 instead of 14

So, changed the command line as below

./build/qos_sched -c 0x16 -n 1 --socket-mem 1024,0 -- --pfc "0,1,2,4" --cfg ./profile.cfg

After running getting a different error as shown below.

Could you help me in running this app as per my system configuration.

Thanks Jasvinder,

Does this application works on systems with multiple NUMA Nodes ?

Thanks,

In default profile.cfg, It is assumed that all the nic ports have 10 Gbps rate. The above error occurs when subport's  tb_rate (10Gbps) is found more than NIC port's capacity (1 Gbps). Therefore, you need to use either 10 Gbps ports in your application or have to amend the profile.cfg to work with 1 Gbps port.  Please refer to  DPDK QoS framework document for more details on various parameters - http://dpdk.org/doc/guides/prog_guide/qos_framework.html

I guess you are reserving less memory using --socket-mem. In qos_sched, each mbuf has (1528 + sizeof(struct rte_mbuf) + RTE_PKTMBUF_HEADROOM)  bytes and we have mempool size equal to 2*1024*1024 mbufs. Altogether it becomes approx. 4 GB. So, try using default memory allocated using hugepages or in case, if you want to use less than default ,   may use --socket-mem  5120,0   

Please refer source code as well to get an idea on memory requirements for this application.
