This patch series implements conditional monitoring by introducing an OVSDB RFC extension with 2 new JSON-RPC methods: "monitor_cond" and "monitor_cond_update". Specification of this extension is defined in the ovsdb-server (1) man page. Monitor2 is now merged into monitor_cond. A monitor_cond session with an empty condition, will behave exactly like monitor2 and will get update2 notifications on all rows.
This patch series is also available on: https://github.com/liranschour/ovs.git branch monitor_cond_ovn. OVN: Last patch in this series is a RFC for OVN usage of conditional monitoring. Performance evaluation: OVN is the main candidate for conditional monitoring usage. It is clear that conditional monitoring reduces computation on the ovn-controller (client) side due to the reduced size of flow tables and update messages. However, performance evaluation shows also a reduction in computation on the SB ovsdb-server side proportional to the degree that each logical network is spread over physical hosts in the DC. Evaluation on simulated environment of 50 hosts and 1000 logical ports shows the following results (cycles #): LN spread over # hosts| master | patch | change ------------------------------------------------------------- 1 | 58855158082 | 38175941755 | 35.1% 3 | 54816462604 | 40255584120 | 26.5% 6 | 52972265506 | 39481653891 | 25.4% 12 | 57036827284 | 42008285519 | 26.3% 18 | 61900476558 | 45903107035 | 25.8% 24 | 64281399690 | 55617752599 | 13.4% 30 | 66905128558 | 61835913623 | 7.5% 42 | 76763742331 | 70522724721 | 8.1% 50 | 85372146321 | 80130285454 | 6.1% Liran Schour (11): ovsdb: create column index mapping between ovsdb row to monitor row ovsdb: add conditions utilities to support monitor_cond ovsdb: allow unmonitored columns in condition evaluation ovsdb: generate update notifications for monitor_cond session ovsdb-client: support monitor-cond method ovsdb: enable jsonrpc-server to service "monitor_cond_update" request lib: add to ovsdb-idl monitor_id lib: add monitor_cond_update API to C IDL lib python: move Python idl to work with monitor_cond tests: add testing for idl conditional monitoring RFC OVN: Quick implementation of conditional monitoring NEWS | 3 +- lib/ovsdb-idl-provider.h | 13 + lib/ovsdb-idl.c | 250 ++++++++++++++++-- lib/ovsdb-idl.h | 39 +++ ovn/controller/binding.c | 114 +++++++- ovn/controller/binding.h | 4 +- ovn/controller/lport.c | 124 ++++++++- ovn/controller/lport.h | 10 +- ovn/controller/ovn-controller.c | 54 +++- ovn/controller/ovn-controller.h | 8 + ovsdb/condition.c | 186 ++++++++++++- ovsdb/condition.h | 41 ++- ovsdb/jsonrpc-server.c | 222 ++++++++++++++-- ovsdb/jsonrpc-server.h | 2 +- ovsdb/monitor.c | 572 +++++++++++++++++++++++++++++++++++----- ovsdb/monitor.h | 35 ++- ovsdb/ovsdb-client.1.in | 37 ++- ovsdb/ovsdb-client.c | 70 +++-- ovsdb/ovsdb-idlc.in | 336 +++++++++++++++++++++++ ovsdb/ovsdb-server.1.in | 230 ++++++++++++++-- ovsdb/ovsdb-server.c | 20 +- ovsdb/query.c | 6 +- python/ovs/db/data.py | 16 +- python/ovs/db/idl.py | 172 ++++++++++-- tests/ovs-vswitchd.at | 8 +- tests/ovsdb-condition.at | 41 +++ tests/ovsdb-idl.at | 243 ++++++++++++++++- tests/ovsdb-monitor.at | 207 +++++++++++++++ tests/test-ovsdb.c | 271 ++++++++++++++++++- tests/test-ovsdb.py | 27 ++ 30 files changed, 3107 insertions(+), 254 deletions(-) -- 2.1.4 _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
