- test methodology and test environment;\r
-\r
- - Tests with varying Qemu virtio queue (a.k.a. vring) sizes:\r
- [vr256] default 256 descriptors, [vr1024] 1024 descriptors to\r
- optimize for packet throughput;\r
-\r

- settings: [cfs] default settings, [cfsrr1] CFS RoundRobin(1)\r
- policy applied to all data plane threads handling test packet\r
- path including all VPP worker threads and all Qemu testpmd\r
- poll-mode threads;\r
-\r
- - Resulting test cases are all combinations with [vr256,vr1024] and\r
- [cfs,cfsrr1] settings;\r
-\r
- - For more detail see performance results observations section in\r
- this report;\r
-\r
-#. Code updates and optimizations in CSIT performance framework:\r
-\r
- - Complete CSIT framework code revision and optimizations as descried\r
- on CSIT wiki page\r
- `Design_Optimizations <https://wiki.fd.io/view/CSIT/Design_Optimizations>`_.\r
-\r
- - For more detail see the CSIT Framework Design section in this\r
- report;\r
-\r
-#. Changes to CSIT driver for TRex Traffic Generator:\r
-\r
- - Complete refactor of TRex CSIT driver;\r
-\r
- - Introduction of packet traffic profiles to improve usability and\r
- manageability of traffic profiles for a growing number of test\r
- scenarios.\r
-\r
- - Support for packet traffic profiles to test IPv4/IPv6 stateful and\r
- stateless DUT data plane features;\r
-\r
-#. Added VPP performance tests\r
-\r
- - **Linux Container VPP memif virtual interface tests**\r
-\r
- - VPP Memif virtual interface (shared memory interface) tests\r
- interconnecting VPP instances over memif. VPP vswitch\r
- instance runs in bare-metal user-mode handling Intel x520 NIC\r
- 10GbE interfaces and connecting over memif (Master side) virtual\r
- interfaces to another instance of VPP running in bare-metal Linux\r
- Container (LXC) with memif virtual interfaces (Slave side). LXC\r
- runs in a priviliged mode with VPP data plane worker threads\r
- pinned to dedicated physical CPU cores per usual CSIT practice.\r
- Both VPP run the same version of software. This test topology is\r
- equivalent to existing tests with vhost-user and VMs.\r
-\r
- - **Stateful Security Groups**\r
-\r
- - New tests of VPP stateful security-groups a.k.a. acl-plugin\r
- functionally compatible with networking-vpp OpenStack;\r
-\r
- - New tested security-groups access-control-lists (acl)\r
- configuration variants include: [iaclNsl] input acl stateless,\r
- [oaclNsl] output acl stateless, [iaclNsf] input acl stateful\r
- a.k.a. reflect, [oaclNsf] output acl stateful a.k.a. reflect,\r
- where N is number of access-control-entries (ace) in the acl.\r
-\r
- - Testing packet flows transmitted by TG: 100, 10k, 100k, always\r
- hitting the last permit entry in acl.\r
-\r
- - **VPP vhost and VM tests**\r
-\r
- - New VPP vhost-user and VM test cases to benchmark performance of\r
- VPP and VM topologies with Qemu and CFS policy combinations of\r
- [vr256,vr1024] x [cfs,cfsrr1];\r
-\r
- - Statistical analysis of repeatibility of results;\r
-\r

+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
+ configurable trial duration and number of consecutive executions.
+ Coverage of MRR tests has been extended across more test
+ scenarios. MRR tests are used for continuous performance trending
+ and for comparison between VPP releases.
+
+ - **MLRsearch Throughput**: MLRsearch algorithm has been introduced
+ for all NDR and PDR throughput tests. All tests that previously
+ used binary search got converted to MLRsearch. Coverage of NDR/PDR
+ tests has been extended across more test scenarios.
+
+ - **L2patch Tests**: Tests measure performance of VPP L2patch, the
+ fastest L2 forwarding path implemented in VPP, that cross-links
+ RX and TX of two physical interfaces.
+
+ - **2-Node Tests**: A new baseline set of 2-node tests covering base
+ ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake
+ testbeds.
+
+ - **Generated tests**: Simplified and unified test structure, semi-
+ autogenerated by generator script. Test generator is currently
+ able to create test combinations with various frame size and
+ cores combinations. All existing test cases were converted to new
+ format.
+
+ - **Simultaneous Multi-Threading**: SMT-aware detection of server
+ processor operation mode (HyperThreading enabled/disabled) with
+ associated compute resource configuration including thread
+ affinity, number of Rx queues and DPDK I/O mbufs. Tests are
+ automatically tagged during execution to indicate executed thread
+ configuration.
+
+ - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node
+ physical testbed topologies based on the new SuperMirco servers
+ each with two Intel Xeon Skylake Platinum processors. Full
+ Ansible playbooks refactor for quick server (re)installation and
+ reference pointers of configuration.
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Performance trending**: Further improvements of continuous
+ performance trending, anomaly detection and analysis.
+
+#. TEST FRAMEWORK OPTIMIZATIONS
+
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
+ removal of redundant RF keywords.
