Bottlenecks - System Limitation Testing
Table of Contents
This project aims to find system bottlenecks by testing and verifying OPNFV infrastructure in a staging environment before committing it to a production environment. Instead of debugging a deployment in production environment, an automatic method for executing benchmarks which plans to validate the deployment during staging is adopted. This project will provide a framework to find the bottlenecks of OPNFV infrastructure. The framework has four components: Workload generator and VNFs (WV), Monitor and Analysis (MA), Deployment and Configuration (DC), Automated Staging (AS). The architecture is shown as follow:
The functions of each components are as below.
Workload generator and VNFs: workload generator generates workloads which go through VNFs
Monitor and Analysis: monitor VNFs status and infrastructure status to output analyzed results
Deployment and Configuration: deploy and configure infrastructure and WV
Automated Staging: implement automated staging
The scope of Bottlenecks project includes:
Forming a staging test framework
Release candidates A,B... provides a foundation to be tested of Infrastructure layer
A workload generator generates workloads which go through VNFs. This workload generator will be scalable and may cover multiply workload models for different scenarios
Monitor and analysis units will monitor the infrastructure and VNFs status and present results after analysis
Automatically generating the full set of experimental specification
Document and codes to describe how to generate experimental specification according to different service level agreement (SLA)
Document to describe how to find some typical bottlenecks according to specific monitoring
Measuring the performance of standard benchmarks over a wide range of hardware and software configurations
Different hardware resource adopted to produce test data used for bottleneck analysis
Different parameters adopted in software configuration files to produce test data used for bottleneck analysis
Automated iterative staging process for finding bottlenecks
Achieve full automation in system deployment, evaluation, and evolution, by creating code generation tools to link the different steps of deployment, evaluation, reconfiguration, and redesign in full lifecycle.
Reassignment and reconfiguration of hardware resources
Reassignment and reconfiguration of software resource
