-==================\r
-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. Test environment changes in VPP data plane performance tests:\r
-\r
- - Further characterization and optimizations of VPP vhost-user and VM\r
- 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
- - Tests with varying Linux CFS (Completely Fair Scheduler)\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
+
+ - **Service density 2n-skx tests**: Network Function Virtualization (NFV)
+ service density tests focus on measuring total per server throughput at
+ varied NFV service *packing* densities with vswitch providing host
+ dataplane. The goal is to compare and contrast performance of a shared
+ vswitch for different network topologies and virtualization technologies,
+ and their impact on vswitch performance and efficiency in a range of NFV
+ service configurations.
+
+ - **Experimental Soak Tests**: Added performamce soak tests framework
+ code for extended time duration tests and throughput discovery
+ at given PLR and at give total test time e.g. minutes, hours,
+ days, weeks, months, years. See updated
+ :ref:`test_methodology` section for more details.
+
+#. TEST FRAMEWORK
+
+ - **Container code optimizations**: Optimized container library allows to
+ run containre_memif tests faster.
+
+ - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to
+ PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away
+ from VAT.
+
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
+ removal of redundant RF keywords.
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Graphs Layout Improvements**: Improved performance graphs layout
+ for better readibility and maintenance: test grouping, axis
+ labels, descriptions, other informative decoration.
+
+#. MISCELLANEOUS
+
+ - **3n-dnv Tests (3rd Party)**: Published performance tests for 3n-
+ dnv (3-Node Atom Denverton) from 3rd party testbeds running FD.io
+ |csit-release| automated testing code.
+ Only graphs for Packet Throughput and Speedup Multi-core and not
+ for Packet Latency were published as there are no results for Packet
+ Latency available.
