From: Numan Siddique <num...@ovn.org> This patch series tries to handle port binding, datapath binding and ovs interface changes incrementally.
First 2 patches does some refactoring. Submitting this as RFC to get some comments. Still need to update the proper commit messages and fix one test case related to Incremental processing which is failing. Another test case related to Interconnection is failing. 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 | 0.484 | 0.507 | 0.526 | 0.537 | 0.547 | 0.51 | 100.0% | 100 | | ovn.create_port_acls | 0.948 | 1.014 | 1.05 | 1.06 | 1.089 | 1.016 | 100.0% | 100 | | ovn_network.bind_port | 1.244 | 1.294 | 1.333 | 1.346 | 1.397 | 1.301 | 100.0% | 100 | | ovn.bind_ovs_vm | 0.379 | 0.432 | 0.463 | 0.469 | 0.472 | 0.434 | 100.0% | 100 | | ovn.bind_internal_vm | 0.824 | 0.861 | 0.897 | 0.906 | 0.941 | 0.868 | 100.0% | 100 | | ovn_network.wait_port_ping | 7.153 | 7.183 | 7.214 | 7.22 | 7.237 | 7.185 | 100.0% | 100 | | total | 10.373 | 10.479 | 10.544 | 10.551 | 10.581 | 10.483 | 100.0% | 100 | +----------------------------------+--------+--------+--------+--------+--------+--------+---------+-------+ Load duration: 1048.8911039829254 Full duration: 1050.4055325984955 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 | 0.479 | 0.492 | 0.513 | 0.52 | 0.531 | 0.495 | 100.0% | 100 | | ovn.create_port_acls | 0.946 | 0.964 | 0.998 | 1.001 | 1.041 | 0.969 | 100.0% | 100 | | ovn_network.bind_port | 1.22 | 1.297 | 1.342 | 1.36 | 1.402 | 1.298 | 100.0% | 100 | | ovn.bind_ovs_vm | 0.373 | 0.418 | 0.436 | 0.455 | 0.472 | 0.42 | 100.0% | 100 | | ovn.bind_internal_vm | 0.818 | 0.88 | 0.911 | 0.93 | 0.982 | 0.878 | 100.0% | 100 | | ovn_network.wait_port_ping | 3.812 | 3.854 | 3.906 | 3.934 | 4.015 | 3.861 | 100.0% | 100 | | total | 6.977 | 7.165 | 7.277 | 7.308 | 7.401 | 7.176 | 100.0% | 100 | +----------------------------------+-------+--------+--------+--------+-------+-------+---------+-------+ Load duration: 718.401807308197 Full duration: 719.8932237625122 Testing the same with fresh OVN dbs didn't show any improvements in the timings. v1 -> 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.
