Added VPP performance tests - - - **Container Service Chain Topologies Orchestrated by K8s with VPP Memif** - - - Added tests with VPP vswitch in container connecting a number of VPP- - in-container service chain topologies with L2 Cross-Connect and L2 - Bridge-Domain configurations, orchestrated by Kubernetes. Added - following forwarding topologies: i) "Parallel" with packets flowing from - NIC via VPP to container and back to VPP and NIC; ii) "Chained" (a.k.a. - "Snake") with packets flowing via VPP to container, back to VPP, to next - container, back to VPP and so on until the last container in a chain, - then back to VPP and NIC; iii) "Horizontal" with packets flowing via VPP - to container, then via "horizontal" memif to next container, and so on - until the last container, then back to VPP and NIC; - - - **VPP TCP/IP stack** - - - Added tests for VPP TCP/IP stack using VPP built-in HTTP server. - WRK traffic generator is used as a client-side; - - - **SRv6** - - - Initial SRv6 (Segment Routing IPv6) tests verifying performance of - IPv6 and SRH (Segment Routing Header) encapsulation, decapsulation, - lookups and rewrites based on configured End and End.DX6 SRv6 egress - functions; - - - **IPSecSW** - - - SW computed IPSec encryption with AES-GCM, CBC-SHA1 ciphers, in - combination with IPv4 routed-forwarding; - -#. Presentation and Analytics Layer - - - Added throughput speedup analysis for multi-core and multi-thread - VPP tests into Presentation and Analytics Layer (PAL) for automated - CSIT test results analysis; - -#. Other changes - - - **Framework optimizations** - - - Ability to run CSIT framework on ARM architecture; - - - Overall stability improvements; - - - **NDR and PDR throughput binary search change** - - - Increased binary search resolution by reducing final step from - 100kpps to 50kpps; - - - **VPP plugin loaded as needed by tests** - - - From this release only plugins required by tests are loaded at - VPP initialization time. Previously all plugins were loaded for - all tests; - -Performance Changes -------------------- - -Relative performance changes in measured packet throughput in CSIT -|release| are calculated against the results from CSIT |release-1| -report. Listed mean and standard deviation values are computed based on -a series of the same tests executed against respective VPP releases to -verify test results repeatibility, with percentage change calculated for -mean values. Note that the standard deviation is quite high for a small -number of packet throughput tests, what indicates poor test results -repeatability and makes the relative change of mean throughput value not -fully representative for these tests. The root causes behind poor -results repeatibility vary between the test cases. - -NDR Throughput Changes -~~~~~~~~~~~~~~~~~~~~~~ - -NDR small packet throughput changes between releases are available in a CSV and -pretty ASCII formats: - - - `csv format for 1t1c <../_static/vpp/performance-changes-ndr-1t1c-full.csv>`_, - - `csv format for 2t2c <../_static/vpp/performance-changes-ndr-2t2c-full.csv>`_, - - `pretty ASCII format for 1t1c <../_static/vpp/performance-changes-ndr-1t1c-full.txt>`_, - - `pretty ASCII format for 2t2c <../_static/vpp/performance-changes-ndr-2t2c-full.txt>`_. - -PDR Throughput Changes -~~~~~~~~~~~~~~~~~~~~~~ - -NDR small packet throughput changes between releases are available in a CSV and -pretty ASCII formats: - - - `csv format for 1t1c <../_static/vpp/performance-changes-pdr-1t1c-full.csv>`_, - - `csv format for 2t2c <../_static/vpp/performance-changes-pdr-2t2c-full.csv>`_, - - `pretty ASCII format for 1t1c <../_static/vpp/performance-changes-pdr-1t1c-full.txt>`_, - - `pretty ASCII format for 2t2c <../_static/vpp/performance-changes-pdr-2t2c-full.txt>`_. - -Measured improvements are in line with VPP code optimizations listed in -`VPP-18.01 release notes -`_. - -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 (1 in 200) NDR discovery test failures | CSIT-570 | DPDK reporting rx-errors, indicating L1 issue.
