CSIT Release Notes ================== Changes in CSIT |release| ------------------------- #. Added VPP performance tests - **Container Topologies Orchestrated by K8s with VPP memif tests** - Added tests with VPP in L2 Cross-Connect and Bridge-Domain configurations containers, with service chain topologies 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 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 tests** - Initial SRv6 tests verifying performance of SRv6 encapsulation and decapsulation and SID lookups. - **IPSecSW tests** - 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 improvements - **Framework optimizations** - Ability to run CSIT framework on ARM architecture. - Overall stability improvements. Performance Improvements ------------------------ Substantial improvements in measured packet throughput have been observed in a number of CSIT |release| tests listed below, with relative increase of double-digit percentage points. Relative improvements for this release are calculated against the test results listed in CSIT |release-1| report. The comparison is calculated between the mean values based on collected and archived test results' samples for involved VPP releases. Standard deviation has been also listed for CSIT |release|. Performance numbers since release VPP-16.09 are provided for reference.

Other Performance Changes ------------------------- Other changes in measured packet throughput, with either minor relative increase or decrease, have been observed in a number of CSIT |release| tests listed below. Relative changes are calculated against the test results listed in CSIT |release-1| report.
