Added VPP performance tests -#. Changes to CSIT driver for TRex Traffic Generator: + - **Container Topologies Orchestrated by K8s with VPP memif tests** - - Complete refactor of TRex CSIT driver; + - 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;. - - Introduction of packet traffic profiles to improve usability and - manageability of traffic profiles for a growing number of test - scenarios. + - **VPP TCP/IP stack** - - Support for packet traffic profiles to test IPv4/IPv6 stateful and - stateless DUT data plane features; + - Added tests for VPP TCP/IP stack using VPP built-in HTTP server. + WRK traffic generator is used as a client-side. -#. Added VPP performance tests + - **SRv6 tests** - - **Linux Container VPP memif virtual interface tests** + - Initial SRv6 tests verifying performance of SRv6 encapsulation and + decapsulation and SID lookups. - - VPP Memif virtual interface (shared memory interface) tests - interconnecting VPP instances over memif. VPP vswitch - instance runs in bare-metal user-mode handling Intel x520 NIC - 10GbE interfaces and connecting over memif (Master side) virtual - interfaces to another instance of VPP running in bare-metal Linux - Container (LXC) with memif virtual interfaces (Slave side). LXC - runs in a priviliged mode with VPP data plane worker threads - pinned to dedicated physical CPU cores per usual CSIT practice. - Both VPP run the same version of software. This test topology is - equivalent to existing tests with vhost-user and VMs. + - **IPSecSW tests** - - **Stateful Security Groups** + - SW computed IPSec encryption with AES-GCM, CBC-SHA1 ciphers, in + combination with IPv4 routed-forwarding. - - New tests of VPP stateful security-groups a.k.a. acl-plugin - functionally compatible with networking-vpp OpenStack; +#. Presentation and Analytics Layer - - New tested security-groups access-control-lists (acl) - configuration variants include: [iaclNsl] input acl stateless, - [oaclNsl] output acl stateless, [iaclNsf] input acl stateful - a.k.a. reflect, [oaclNsf] output acl stateful a.k.a. reflect, - where N is number of access-control-entries (ace) in the acl. + - Added throughput speedup analysis for multi-core and multi-thread + VPP tests into Presentation and Analytics Layer (PAL) for automated + CSIT test results analysis; - - Testing packet flows transmitted by TG: 100, 10k, 100k, always - hitting the last permit entry in acl. +#. Other improvements - - **VPP vhost and VM tests** + - **Framework optimizations** - - New VPP vhost-user and VM test cases to benchmark performance of - VPP and VM topologies with Qemu and CFS policy combinations of - [vr256,vr1024] x [cfs,cfsrr1]; + - Ability to run CSIT framework on ARM architecture. - - Statistical analysis of repeatibility of results; + - Overall stability improvements.
