+Changes in CSIT |release|\r
-------------------------\r
\r
-#. VPP performance test environment changes\r
+#. Test environment changes in VPP data plane performance tests:\r
\r
- - further VM and vhost-user test environment optimizations - Qemu virtio queue size increased from default value of 256 to 1024\r
- - addition of HW cryptodev devices in all three LF FD.io physical testbeds\r
+ - Further characterization and optimizations of VPP vhost-user and VM\r
+ test methodology and test environment;\r
\r
-#. Added tests (to be updated)\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
- - NICs\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
- - Intel x710 (L2 Bridge Domain switched-forwarding, vhost-user)\r
- - Cisco VIC1385 (L2 Bridge Domain switched-forwarding)\r
- - Cisco VIC1227 (L2 Bridge Domain switched-forwarding)\r
+ - Resulting test cases are all combinations with [vr256,vr1024] and\r
+ [cfs,cfsrr1] settings;\r
\r
- - vhost-user tests with VM\r
+ - For more detail see performance results observations section in\r
+ this report;\r
\r
- - L2 Bridge Domain switched-forwarding with Intel x710 NIC\r
- - L2 Bridge Domain switched-forwarding with VxLAN and Intel x520 NIC\r
- - L2 Bridge Domain switched-forwarding with Intel xl710 NIC\r
+#. Code updates and optimizations in CSIT performance framework:\r
\r
- - Tests with VxLAN\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
- - L2 Bridge Domain switched-forwarding with Intel x520 NIC\r
- - L2 Bridge Domain switched-forwarding with vhost-user, VM and Intel x520\r
- NIC\r
+ - For more detail see the CSIT Framework Design section in this\r
+ report;\r
\r
-Performance Improvements - to be updated\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
+Performance Improvements\r
------------------------\r
\r
-Substantial improvements in measured packet throughput, with relative increase\r
-of double-digit percentage points, have been observed in a number of CSIT\r
-|release| tests listed below. Relative improvements are calculated against the\r
-test results in CSIT rls1701 report.\r
+Substantial improvements in measured packet throughput have been\r
+observed in a number of CSIT |release| tests listed below, with relative\r
+increase of double-digit percentage points. Relative improvements for\r
+this release are calculated against the test results listed in CSIT\r
+|release-1| report. The comparison is calculated between the mean values\r
