-CSIT Release Notes\r
-==================\r
-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. **Added VPP performance tests**\r
-\r
- - **MRR tests** : New MRR tests measure the packet forwarding rate\r
- under the maximum load offered by traffic generator over a set\r
- trial duration, regardless of packet loss. Maximum load for\r
- specified Ethernet frame size is set to the bi-directional link\r
- rate. MRR tests are used for continuous performance trending and\r
- for comparison between releases.\r
-\r
- - **Service Chaining with SRv6** : SRv6 (Segment Routing IPv6) proxy tests\r
- verifying performance of Endpoint to SR-unaware appliance via\r
- masquerading (End.AM), dynamic proxy (End.AD) or static proxy (End.AS)\r
- functions.\r
-\r
-#. **Presentation and Analytics Layer (PAL)**\r
-\r
- - Added continuous performance measuring, trending and anomaly\r
- detection. Includes new PAL code and Jenkins jobs for Performance\r
- Trending (PT) and Performance Analysis (PA) producing performance\r
- trending dashboard and trendline graphs with summary and drill-\r
- down views across all specified tests that can be reviewed and\r
- inspected regularly by FD.io developers and users community.\r
-\r
-#. **Test Framework Optimizations**\r
-\r
- - **Performance tests efficiency** : Qemu build/install\r
- optimizations, warmup phase handling, vpp restart handling.\r
- Resulted in improved stability and reduced total execution time by\r
- 30% for single pkt size e.g. 64B/78B.\r
-\r
- - **General code housekeeping** : ongoing RF keywords\r
- optimizations, removal of redundant RF keywords.\r
-\r
-Performance Changes\r
--------------------\r
-\r
-Relative performance changes in measured packet throughput in CSIT\r
-|release| are calculated against the results from CSIT |release-1|\r
-report. Listed mean and standard deviation values are computed based on\r
-a series of the same tests executed against respective VPP releases to\r
-verify test results repeatibility, with percentage change calculated for\r
-mean values. Note that the standard deviation is quite high for a small\r
-number of packet throughput tests, what indicates poor test results\r
-repeatability and makes the relative change of mean throughput value not\r
-fully representative for these tests. The root causes behind poor\r
-results repeatibility vary between the test cases.\r
-\r

-Known Issues\r
-------------\r
-\r
-<to be updated before rls1804 release>\r
-\r
-Here is the list of known issues in CSIT |release| for VPP performance tests:\r
-\r
-+---+-------------------------------------------------+------------+-----------------------------------------------------------------+\r
-| # | Issue | Jira ID | Description |\r
-+---+-------------------------------------------------+------------+-----------------------------------------------------------------+\r
-| 1 | Vic1385 and Vic1227 low performance. | VPP-664 | Low NDR performance. |\r
-| | | | |\r
-+---+-------------------------------------------------+------------+-----------------------------------------------------------------+\r
-| 2 | Sporadic (1 in 200) NDR discovery test failures | CSIT-570 | DPDK reporting rx-errors, indicating L1 issue. Suspected issue |\r

-| | | | outside of LF testbeds. |\r
-+---+-------------------------------------------------+------------+-----------------------------------------------------------------+\r
