From: Numan Siddique <[email protected]> This patch series handles port binding, datapath binding, ovs interface changes, runtime data changes, sb chassis changes incrementally.
(These patches can also be found here - https://github.com/numansiddique/ovn/tree/IP_improvements_v5) Below are the results of some testing I did with ovn-fake-multinode setup Test setup ------ 1. ovn-central fake node running OVN dbs and 2 compute nodes running ovn-controller. 2. Before running the tests, used an existing OVN db with the below resources No of logical switches - 53 No of logical ports - 1256 No of logical routers - 9 No of logical router ports - 56 No of port groups - 152 No of logical flows - 45447 Port bindings on compute-1 - 19 Port bindings on compute-2 - 18 No of OF flows on compute-1 - 84996 No of OF flows on compute-2 - 84901 3. The test does the following - Creates 2 logical switches (one for each compute node) and connect to a logical router for each compute node. - 100 logical ports are created (50 per lswitch), a simple ACL is added and the address set is created for each port. - Each port is bound on the respective compute node and the test pings the IP of the port (from another port belonging to the same lswitch created earlier). Below are the results with OVN master +---------------------------------------------------------------------------------------------------------+ | Response Times (sec) | +----------------------------------+-------+--------+--------+--------+--------+--------+---------+-------+ | action | min | median | 90%ile | 95%ile | max | avg | success | count | +----------------------------------+-------+--------+--------+--------+--------+--------+---------+-------+ | ovn.create_or_update_address_set | 0.491 | 0.519 | 0.542 | 0.548 | 0.558 | 0.521 | 100.0% | 100 | | ovn.create_or_update_port_group | 0.0 | 0.0 | 0.0 | 0.0 | 0.001 | 0.0 | 100.0% | 100 | | ovn.create_port_group_acls | 0.966 | 1.037 | 1.065 | 1.069 | 1.07 | 1.037 | 50.0% | 100 | | ovn_network.bind_port | 1.242 | 1.341 | 1.397 | 1.409 | 1.443 | 1.348 | 100.0% | 100 | | ovn.bind_ovs_vm | 0.413 | 0.469 | 0.49 | 0.494 | 0.523 | 0.469 | 100.0% | 100 | | ovn.bind_internal_vm | 0.804 | 0.875 | 0.921 | 0.935 | 0.95 | 0.88 | 100.0% | 100 | | ovn_network.wait_port_ping | 6.695 | 7.788 | 7.903 | 11.63 | 16.124 | 7.997 | 100.0% | 100 | | total | 9.271 | 10.318 | 11.269 | 14.047 | 18.509 | 10.871 | 100.0% | 100 | +----------------------------------+-------+--------+--------+--------+--------+--------+---------+-------+ Load duration: 1087.5742933750153 Full duration: 1089.151035308838 Below are the results with these patches +-------------------------------------------------------------------------------------------------------+ | Response Times (sec) | +----------------------------------+-------+--------+--------+--------+-------+-------+---------+-------+ | action | min | median | 90%ile | 95%ile | max | avg | success | count | +----------------------------------+-------+--------+--------+--------+-------+-------+---------+-------+ | ovn.create_or_update_address_set | 0.484 | 0.506 | 0.53 | 0.536 | 0.551 | 0.509 | 100.0% | 100 | | ovn.create_or_update_port_group | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 0.0 | 100.0% | 100 | | ovn.create_port_group_acls | 0.966 | 1.006 | 1.032 | 1.036 | 1.059 | 1.006 | 50.0% | 100 | | ovn_network.bind_port | 1.255 | 1.352 | 1.421 | 1.444 | 1.516 | 1.352 | 100.0% | 100 | | ovn.bind_ovs_vm | 0.411 | 0.455 | 0.472 | 0.476 | 0.5 | 0.456 | 100.0% | 100 | | ovn.bind_internal_vm | 0.806 | 0.893 | 0.968 | 0.989 | 1.043 | 0.896 | 100.0% | 100 | | ovn_network.wait_port_ping | 0.226 | 0.253 | 0.325 | 0.329 | 0.347 | 0.267 | 100.0% | 100 | | total | 2.517 | 3.137 | 3.718 | 3.749 | 3.797 | 3.135 | 100.0% | 100 | +----------------------------------+-------+--------+--------+--------+-------+-------+---------+-------+ Load duration: 313.99292826652527 Full duration: 315.29931354522705 I ran same tests but with 1000 lports and below are the results with these patches +-------------------------------------------------------------------------------------------------------+ | Response Times (sec) | +----------------------------------+-------+--------+--------+--------+-------+-------+---------+-------+ | action | min | median | 90%ile | 95%ile | max | avg | success | count | +----------------------------------+-------+--------+--------+--------+-------+-------+---------+-------+ | ovn.create_or_update_address_set | 0.483 | 0.555 | 0.6 | 0.615 | 0.661 | 0.555 | 100.0% | 1000 | | ovn.create_or_update_port_group | 0.0 | 0.0 | 0.0 | 0.0 | 0.002 | 0.0 | 100.0% | 1000 | | ovn.create_port_group_acls | 0.973 | 1.101 | 1.176 | 1.195 | 1.271 | 1.097 | 50.0% | 1000 | | ovn_network.bind_port | 1.239 | 1.371 | 1.444 | 1.47 | 1.557 | 1.373 | 100.0% | 1000 | | ovn.bind_ovs_vm | 0.409 | 0.482 | 0.522 | 0.541 | 0.597 | 0.486 | 100.0% | 1000 | | ovn.bind_internal_vm | 0.784 | 0.882 | 0.945 | 0.968 | 1.063 | 0.887 | 100.0% | 1000 | | ovn_network.wait_port_ping | 0.218 | 0.251 | 0.313 | 0.324 | 0.395 | 0.262 | 100.0% | 1000 | | total | 2.465 | 3.251 | 3.956 | 4.016 | 4.226 | 3.274 | 100.0% | 1000 | +----------------------------------+-------+--------+--------+--------+-------+-------+---------+-------+ Load duration: 3279.292845249176 Full duration: 3280.6857619285583 v4 -> v5 ---- * Applied patch 1 of v4 to master. * Addressed the review comments from Han for patch 2. * Rebased to latest master. v3 -> v4 ---- * A small fix in patch 3 when binding the port for ovs interface change. * Rebased to latest master. v2 -> v3 ---- * Added back the patch 5 and 6 and added 4 more patches. So totally totally 10 patches in the series * Handling the runtime data changes in flow computation. * Handling sbrec_chassis changes. v1 -> v2 ------ * Addressed the review comments from Han in patch 1, 2 and 3. * Removed patch 5 and 6 from the series. As per the comments from Han, we should handle runtime data changes in flow output engine. But the patch 6 of the series had added a no-op handler. So removed these 2 patches until those are addressed. RFC v2 -> v1 --------- * Fixed the 2 failing test cases. * Updated the commit messages. RFC v1 -> RFC v2 --------- * Added 2 new patches * Patch 5 (ofctrl_check_and_add_flow) was submitted earlier too and the previous discussion is here - https://patchwork.ozlabs.org/patch/1202417/ * Patch 6 handles I-P for ct_zone and OVS interface changes in flow_output_run stage.
