Introduction

The colored blocks shows the current Features of VSPERF, the White-blocks shows the features we plan to add to VSPERF, in near future.


Significance of VSPERF

VSPERF Only

VSPERF can be used for both Lab and Production/Live Environments, as summarized in the figure below. Typically, in cloud deployments, Telcos define set of "Acceptance Tests" (AT) for cloud. Performance testcases can be part of this AT, and VSPERF is the ideal tool to be used to run those testcases.



VSPERF with other OPNFV Testing Projects:

Similar to NFVBench, measure and assess the L2/L3 forwarding performance of an NFV-infrastructure solution stack (i.e. OPNFV scenario) using a black-box approach. It can be agnostic of the installer used, the hardware used, the controller used (ML2/OVS, ODL...), the network stack used (OVS, OVS-DPDK, VPP...).


Five Main Focus Areas of VSPERF for Iruya and Beyond:


Continued Contribution to Standardization

ETSI TST 009 and VSPERF:

Section

Compliance Comments

Missing Aspects

Test Setups

Fully Compliant


Throughput

Missing capacity reporting. Only throughput is reported.

Capacity with X % Loss

Latency

Missing Transfer time in percentile. Other 4 supported.

Transfer Time (Yth percentile, X % Thpt, Filter)

Delay Variation

Missing FDV and IFDV with %le and %ge throughput

FDV (Yth percentile, X % Thpt, Filter) and Inter-Frame Delay Variation (X % Thpt, Filter)

Loss

Missing loss ratio with %ge throughput and loss-free seconds.

Loss Ratio (X % Thpt, Filter), Loss-Free Seconds (X % Thpt, Filter)

Methods of Measurement

Pre-test requirements automated.

Binary Search with LV needs minor update?

NDR/PDR support is lacking.

Setting up Cross-Numa scenarios automated.

Better configuration for Soak-Tests

Binary Search with NDR/PDR is missing

Container Networking Performance Benchmarking

Goal: Automated Setup of DUT, Comparative Study, Generate Results.

The setup requirements:

  1. Single L2 Forwarding Container.
  2. Two interfaces in Container for 'east' and 'west' traffic.
    1. CN solutions multiple interfaces support.
  3. Two Physical Interfaces on the host to which Traffic-Generator is connected.
    1. CN solution to use these 2 physical interfaces.
    2. CN to bridge/route the traffic across physical-physical, physical-virtual, virtual-physical and virtual-virtual interfaces.

To realize the first step of "Automated Setup of DUT", there are different options:

  1. CN without Kubernetes
  2. CN With Kubernetes
    1. Manual
    2. kubeadm
    3. Kubespray + Kubeadm
    4. Multus/DanM
    5. Multus + ? Plugin
    6. Multus + Userspace CNI?

The DUT architecture would be:



Containerization of VSPERF and Integration with Larger Test-Automation Frameworks

Target Frameworks: Dovetail and X-Testing.

This task has two main parts: 

Part-1: Containerizing VSPERF.


Controller Container: Separating Deployment from Testing

No.TitleDescriptionComments
1Auto-DeployThis container takes the following inputs and automatically deploy VSPERF and setup the TGen if required.Ideal for integrating with CI/CD based larger test automation Frameworks
2Interactive-DeployThis container, starts listening to commands from the user to perform the deployment of VSPERF and TGenIdeal for integrating with other 'interactive' (web-based) test automation frameworks.
3Auto-TestControlThis Container takes the following inputs and automatically runs the tests and publishes the results.Ideal for integrating with CI/CD based larger test automation frameworks.
4Interactive-TestControlThis container, starts listening to commands from the user to perform the testing.Ideal for integrating with other 'interactive' (web-based) test automation frameworks.


Part-2: Integrating VSPERF with larger Test-Automation Frameworks

We are targeting both Dovetail and X-testing.

Analytics

Basic Analytics

Reference work, which was demonstrated at ONS-NA 2019 can be accessed here: https://github.com/opensource-tnbt/vsperf-notebooks 

Advanced Analytics

Work in Progress, in collaboration with Unknown User (vipratos)

Ease of use

Configuration Generation Tool: 

A PoC can be found here: https://github.com/opensource-tnbt/vsperfwizard 

GUI based Test management tool.

Reuse Yardstick GUI?

Dashboard

Custom Dashboard to showcase the status of VSPERF Ongoing Test - Topology, Traffic, etc.

We are looking for some volunteers to develop this - Maybe we can reuse 


Other Works:

  1. New vSwitches support - Tungsten vRouter
  2. Kernel Fastpaths (ex: AF_XDP)
