CSIT Performance TCs Naming

Background

Now that the number and type of CSIT test cases (TCs) grew significantly, existing naming notation does not work anymore. Firstly, the existing practice does not always follow any strict naming convention. Secondly current TC names do not always clearly capture packet encapsulations, the actual type or content of the tests. Thirdly HW configurations in terms of NICs, ports and their locality are not captured in the name. Bottom line, to address these points within the CSIT project, we agreed to define a new more complete and stricter TC naming convention, and to apply this to all existing and new test cases.

This wiki page captures this change.

CSIT Tests - Naming

Overview

The approach is to use tree naming convention and to encode following testing information into test names:

1. packet network port configuration
   • physical port type;
   • NIC model;
   • port-NIC locality;
2. packet encapsulations
3. VPP packet processing
   • packet forwarding mode
   • packet processing function(s)
4. packet forwarding path
   • if present, network functions (processes, containers, VMs) and their topology within the computer;
5. main measured variable, type of test;

Proposed convention is to encode physical ports and NIC on the left (underlay), followed by outer most frame header, then other stacked headers up to the header processed by vSwitch-VPP, then VPP forwarding function, then encap on vhost interface, number of vhost interfaces, number of VMs. If chained VMs present, they get added on the right. Test topology is expected to be symmetric, in other words packets enter and leave SUT through ports specified on the left of the test name. Here some examples to illustrate the convention followed by the complete legend, and tables mapping the new test filenames to old ones.

Convention

CSIT test naming convention for common tested VNF topologies:

Throughput NDR Check

Performance Trending Graphs

One of the CSIT goals is to auto-generate VPP performance trending graphs for tested use cases and configurations. Trending graphs are auto-generated for Jenkins csit-perf* jobs using Jenkins plugin <add link> and for CSIT release reports using separate python scripts <add link>. For better readibility VPP performance results are marked with RF tags and grouped into separate graphs as follows:

1. L2BD, L2XC
   • tags: L2BDMACSTAT or L2BDMACLRN or L2XCFWD
2. IPv4 base, scale, feature
   • tags: IP4FWD
3. IPv6 base, scale, feature
   • tags: IP6FWD
4. Overlay tunnels - LISP, VXLAN, GPE, GRE
   • tags: VXLAN or LISP or LISPGPE or VXLANGPE or GRE
5. Crypto in software: IP4FWD, IP6FWD
   • tags: IPSECSW and (IPSECTRAN or IPSECTUN)
6. Crypto in hardware: IP4FWD, IP6FWD
   • tags: IPSECHW and (IPSECTRAN or IPSECTUN)
7. Overlay tunnels with crypto in software
   • tags: (VXLAN or LISP or LISPGPE or VXLANGPE or GRE) and IPSECSW and (IPSECTRAN or IPSECTUN)
8. Overlay tunnels with crypto in hardware
   • tags: (VXLAN or LISP or LISPGPE or VXLANGPE or GRE) and IPSEHW and (IPSECTRAN or IPSECTUN)
9. vhost-user
   • tags: VHOST and (ETH or DOT1Q or VXLAN)

For each of the above, separate graph series is auto-generated for:

1. Throughput type
   1. NDR
      • tags: NDRDISC
   2. PDR
      • tags: PDRDISC
2. Worker thread and core configuration
   1. 1t1c - 1 worker-thread, 1 core
      • tags: 1T1C
   2. 2t2c - 2 worker-threads, 2 cores
      • tags: 2T2C
   3. 4t4c - 4 worker-threads, 4 cores
      • tags: 2T2C

Resulting total number of auto-generated graphs: 9*5 = 45 graphs.

Test RF Tagging for Trending Graphs
