CSIT Release Notes
==================
Changes in CSIT |release|
-------------------------
#. Added VPP performance tests
- **Linux Container VPP memif tests**
- Tests with VPP in L2 Bridge-Domain configuration connecting over
memif virtual interfaces to VPPs running in LXCs;
- **Docker Container VPP memif tests**
- Tests with VPP in L2 Cross-Connect configuration connecting over
memif virtual interfaces VPPs running in Docker containers;
- **Container Topologies Orchestrated by K8s with VPP memif tests**
- Tests with VPP in L2 Cross-Connect and Bridge-Domain configurations
connecting over memif virtual interfaces VPPs running in Docker
containers, with service chain topologies orchestrated by Kubernetes;
- **Stateful Security Groups**
- m-thread m-core VPP stateful and stateless security-groups tests;
- **MAC-IP binding**
- MACIP input access-lists, single-thread single-core and m-thread
m-core tests;
- Statistical analysis of repeatibility of results;
Performance Improvements
------------------------
Substantial improvements in measured packet throughput have been observed in a
number of CSIT |release| tests listed below, with relative increase of
double-digit percentage points. Relative improvements for this release are
calculated against the test results listed in CSIT |release-1| report. The
comparison is calculated between the mean values based on collected and
archived test results' samples for involved VPP releases. Standard deviation
has been also listed for CSIT |release|. Performance numbers since release
VPP-16.09 are provided for reference.

}
Measured improvements are in line with VPP code optimizations listed in
`VPP-17.10 release notes
<https://docs.fd.io/vpp/17.10/release_notes_1710.html>`_.
Other Performance Changes
-------------------------
Other changes in measured packet throughput, with either minor relative increase
or decrease, have been observed in a number of CSIT |release| tests listed
below. Relative changes are calculated against the test results listed in CSIT
|release-1| report.

Known Issues
------------
Here is the list of known issues in CSIT |release| for VPP performance tests:
+---+-------------------------------------------------+------------+-----------------------------------------------------------------+
| # | Issue | Jira ID | Description |
+---+-------------------------------------------------+------------+-----------------------------------------------------------------+
| 1 | Vic1385 and Vic1227 low performance. | VPP-664 | Low NDR performance. |
| | | | |
+---+-------------------------------------------------+------------+-----------------------------------------------------------------+
| 2 | Sporadic NDR discovery test failures on x520. | CSIT-750 | Suspected issue with HW settings (BIOS, FW) in LF |
| | | | infrastructure. Issue can't be replicated outside LF. |
+---+-------------------------------------------------+------------+-----------------------------------------------------------------+
