Added VPP performance tests +#. **Added VPP performance tests** - - **Container Service Chain Topologies Orchestrated by K8s with VPP Memif** + - **MRR tests** : New MRR tests measure the packet forwarding rate + under the maximum load offered by traffic generator over a set + trial duration, regardless of packet loss. Maximum load for + specified Ethernet frame size is set to the bi-directional link + rate. MRR tests are used for continuous performance trending and + for comparison between releases. - - 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; + - **Service Chaining with SRv6** : SRv6 (Segment Routing IPv6) proxy tests + verifying performance of Endpoint to SR-unaware appliance via + masquerading (End.AM), dynamic proxy (End.AD) or static proxy (End.AS) + functions. - - **VPP TCP/IP stack** +#. **Presentation and Analytics Layer (PAL)** - - Added tests for VPP TCP/IP stack using VPP built-in HTTP server. - WRK traffic generator is used as a client-side; + - Added continuous performance measuring, trending and anomaly + detection. Includes new PAL code and Jenkins jobs for Performance + Trending (PT) and Performance Analysis (PA) producing performance + trending dashboard and trendline graphs with summary and drill- + down views across all specified tests that can be reviewed and + inspected regularly by FD.io developers and users community. - - **SRv6** +#. **Test Framework Optimizations** - - 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; + - **Performance tests efficiency** : Qemu build/install + optimizations, warmup phase handling, vpp restart handling. + Resulted in improved stability and reduced total execution time by + 30% for single pkt size e.g. 64B/78B. - - **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; + - **General code housekeeping** : ongoing RF keywords + optimizations, removal of redundant RF keywords.
