8 \r
9    - **Container Topologies Orchestrated by K8s with VPP memif tests**\r
10 \r
11    - Added tests with VPP in L2 Cross-Connect and Bridge-Domain\r
12      configurations containers, with service chain topologies orchestrated by\r
13      Kubernetes. Added following forwarding topologies: i) "Parallel" with\r
14      packets flowing from NIC via VPP to container and back to VPP and NIC;\r
15      ii) "Chained" a.k.a. "Snake" with packets flowing via VPP to container,\r
16      back to VPP, to next container, back to VPP and so on until the last\r
17      container in chain, then back to VPP and NIC; iii) "Horizontal" with\r
18      packets flowing via VPP to container, then via "horizontal" memif to\r
19      next container, and so on until the last container, then back to VPP and\r
20      NIC;.\r
21 \r
22    - **VPP TCP/IP stack**\r
23 \r

28 \r
29      - Initial SRv6 (Segment Routing IPv6) tests verifying performance of\r
30        IPv6 and SRH (Segment Routing Header) encapsulation, decapsulation,\r
31        lookups and rewrites based on configured End and End.DX6 SRv6 egress\r

39 #. Presentation and Analytics Layer\r
40 \r
41      - Added throughput speedup analysis for multi-core and multi-thread\r
42        VPP tests into Presentation and Analytics Layer (PAL) for automated\r

44 \r
45 #. Other improvements\r
46 \r
47      - **Framework optimizations**\r
48 \r
49        - Ability to run CSIT framework on ARM architecture;\r
50 \r
51        - Overall stability improvements;\r
52 \r
53 Performance Improvements\r
54 ------------------------\r
55 \r
56 Substantial improvements in measured packet throughput have been observed in a\r
57 number of CSIT |release| tests listed below, with relative increase of\r
58 double-digit percentage points. Relative improvements for this release are\r
59 calculated against the test results listed in CSIT |release-1| report. The\r
60 comparison is calculated between the mean values based on collected and\r
61 archived test results' samples for involved VPP releases. Standard deviation\r
62 has been also listed for CSIT |release|. Performance numbers since release\r
63 VPP-16.09 are provided for reference.\r
