Project: OSCAR

  • Proposed name for the project: OSCAR (Open Source Carrier grade ARchitecture)
  • Proposed name for the repository: repo-oscar
  • Project Categories: Integration & Testing, Collaborative Development

Project Description

Project “OSCAR” provides a platform that can be used to assemble and test a base set of infrastructure components for the OPNFV. A few example VNFs will be provided to validate the integrity and the overall functionality of the OPNFV implementation platform. The goals of the Oscar Project is closely aligned with what the OPNFV technical steering committee (TSC) is envisioning for the first release. This is fast track the integration of the core open source network components, learn from their differences and commonality of deployment experience, and feed that back into producing a more flexible implementation framework.

The project targets an installation on a virtual environment based on Ubuntu/Trusty as the base operating system and distribution. Oscar provides a solution to automatically install and configure the required components using existing installer and configuration tools and perform a set of basic system level tests (i.e. test whether OpenStack, OpenContrail, network components like vRouter, etc are operational, tests whether a set of VNFs can be deployed/removed on the compute node and more). All components of the project shown in the table below have already been tested and the overall functionality of the aggregate software components has been validated. As such, this platform should serve as a framework to fast track the continuous integration of various components for the first release (targeted for March 2015).

Scope

The scope of the project is captured in the table shown below. As the table indicates all the features and functionality are part of the first release of the OPNFV. Nearly all these features have been tested and integrated within the OpenContrail, an open source platform under the Apache 2.0 license. Various POCs and pre-production version of the OpenContrail have been demonstrated in numerous lab and production systems.

Targeted Test Cases

OSCAR provides automated testing tools for installation of various components as well as health check for individual components. This includes (but not limited to):

  • OpenStack health check,
  • OpenContrail health check,
  • Life cycle management and automated system-level testing: CRUD operations for multiple instances of VNFs, and
  • Life cycle management of associated network services.

VNFs Served by OSCAR:

  • FW/SRX
  • vFW/vSRX (Firefly)
  • vPE
  • vCDN
  • vCPE
  • vMME (vMCG)
  • 3rd Party VNFs

Testability: (optional, Project Categories: Integration & Testing)

Information regarding testing and integration including interoperability, scalability, high availability are provided in the above table. Any additional information for quality assurance and test resources will be available if necessary.

Documentation: (optional, Project Categories: Documentation)

All API-related documents will be available in a timely manner. Detailed description of the Functional Architecture (building blocks, reference points, interfaces and protocols, work flow diagrams, etc.) will be provided during the development, integration and testing processes.

Dependencies:

The OSCAR project relies on the following open source projects:

  • OpenStack Juno release: various components including Nova, Neutron, Ceilometer, Heat, etc.,
  • OpenContrail: vRouter and other components,
  • Installer: Cobbler,
  • Configuration & Management: Puppet,
  • QEMU/KVM,
  • Linux/Ubuntu distribution.

Committers and Contributors:

Planned Deliverables

Project Oscar:

  • Installs scripts for automated deployment of the test setup to a bare metal environment,
  • Test scripts to allow for automated system level testing and component health check of all network functions, software components, etc in both virtual and physical environments,
  • Heat-based orchestration template for delivered sample VNFs as well as other vendors’ VNFs.

Proposed Release Schedule:

  • The first release is targeted for March 2015.
  • The project aligns with the current release cadence.

Questions

  1. is this project approved by TSC already?
