===== Description =====

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 as shown [[https://wiki.opnfv.org/_media/project_proposals/bottlenecksproposal.png?cache=|here]], and 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

===== Scope =====

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
