=====================
Application for rte_flow performance testing.
-The application provide the ability to test insertion rate of specific
-rte_flow rule, by stressing it to the NIC, and calculate the insertion
-rate.
+The application provides the ability to test insertion rate of specific
+rte_flow rule, by stressing it to the NIC, and calculates the insertion
+and deletion rates.
-The application offers some options in the command line, to configure
-which rule to apply.
+The application allows to configure which rule to apply through several
+options of the command line.
After that the application will start producing rules with same pattern
but increasing the outer IP source address by 1 each time, thus it will
give different flow each time, and all other items will have open masks.
-The application also provide the ability to measure rte flow deletion rate,
-in addition to memory consumption before and after the flows creation.
+To assess the rule insertion rate, the flow performance tool breaks
+down the entire number of flow rule operations into windows of fixed size
+(defaults to 100000 flow rule operations per window, but can be configured).
+Then, the flow performance tool measures the total time per window and
+computes an average time across all windows.
-The app supports single and multi core performance measurements.
+The application also provides the ability to measure rte flow deletion rate,
+in addition to memory consumption before and after the flow rules' creation.
-
-Known Limitations
------------------
-
-The current version has limitations which can be removed in future:
-
-* Single core insertion only.
+The app supports single and multiple core performance measurements, and
+support multiple cores insertion/deletion as well.
Compiling the Application
.. code-block:: console
- sudo ./dpdk-test-flow_perf -n 4 -w 08:00.0 -- --ingress --ether --ipv4 --queue --flows-count=1000000
+ sudo ./dpdk-test-flow_perf -n 4 -a 08:00.0 -- --ingress --ether --ipv4 --queue --rules-count=1000000
The command line options are:
* ``--help``
Display a help message and quit.
-* ``--flows-count=N``
- Set the number of needed flows to insert,
- where 1 <= N <= "number of flows".
+* ``--rules-count=N``
+ Set the total number of flow rules to insert,
+ where 1 <= N <= "number of flow rules".
The default value is 4,000,000.
+* ``--rules-batch=N``
+ Set the number of flow rules to insert per iteration window,
+ where 1 <= N <= "number of flow rules per iteration window".
+ The default value is 100,000 flow rules per iteration window.
+ For a total of --rules-count=1000000 flow rules to be inserted
+ and an iteration window size of --rules-batch=100000 flow rules,
+ the application will measure the insertion rate 10 times
+ (i.e., once every 100000 flow rules) and then report an average
+ insertion rate across the 10 measurements.
+
* ``--dump-iterations``
- Print rates for each iteration of flows.
- Default iteration is 1,00,000.
+ Print rates for each iteration window.
+ Default iteration window equals to the rules-batch size (i.e., 100,000).
* ``--deletion-rate``
Enable deletion rate calculations.
* ``--enable-fwd``
Enable packets forwarding after insertion/deletion operations.
+* ``--portmask=N``
+ hexadecimal bitmask of ports to be used.
+
+* ``--cores=N``
+ Set the number of needed cores to insert/delete rte_flow rules.
+ Default cores count is 1.
+
+* ``--meter-profile-alg``
+ Set the traffic metering algorithm.
+ Example: meter-profile-alg=srtcmp, default algorithm is srtcm_rfc2697
+
+* ``--unique-data``
+ Flag to set using unique data for all actions that support data,
+ Such as header modify and encap actions. Default is using fixed
+ data for any action that support data for all flows.
+
+* ``--rxq=N``
+ Set the count of receive queues, default is 1.
+
+* ``--txq=N``
+ Set the count of send queues, default is 1.
+
+* ``--rxd=N``
+ Set the count of rxd, default is 256.
+
+* ``--txd=N``
+ Set the count of txd, default is 256.
+
+* ``--mbuf-size=N``
+ Set the size of mbuf, default size is 2048.
+
+* ``--mbuf-cache-size=N``
+ Set the size of mbuf cache, default size is 512.
+
+* ``--total-mbuf-count=N``
+ Set the count of total mbuf number, default count is 32000.
Attributes:
under ``TAG_INDEX`` with full mask, default value = 0.
Other fields are open mask.
+* ``--icmpv4``
+ Add icmpv4 item to all flows items, This item have open mask.
+
+* ``--icmpv6``
+ Add icmpv6 item to all flows items, This item have open mask.
+
Actions:
* ``--flag``
Add flag action to all flows actions.
+
+* ``--raw-encap=<DATA>``
+ Add raw encap action to all flows actions.
+ Data is the data needed to be encaped, with fixed values.
+ Example: raw-encap=ether,ipv4,udp,vxlan
+
+* ``--raw-decap=<DATA>``
+ Add raw decap action to all flows actions.
+ Data is the data needed to be decaped, with fixed values.
+ Example: raw-decap=ether,ipv4,gre
+
+* ``--vxlan-encap``
+ Add vxlan encap action to all flows actions.
+ Data to encap is fixed with pattern: ether,ipv4,udp,vxlan,
+ all encapped items have fixed values.
+
+* ``--vxlan-decap``
+ Add vxlan decap action to all flows actions.
+
+* ``--meter``
+ Add meter action to all flows actions.
+ Currently, 1 meter profile -> N meter rules -> N rte flows.
