Introduction

Flexible and agile service adaptation at the cost of commodity servers and whitebox switches VOLTHA introduces the next-generation optical access system architecture, based on SDN/NFV technologies. Disaggregating PON functions to functional modules with open interfaces supports the CORD vision for open source reference implementations to service "Access-as-a-Service" use cases.   VOLTHA  is a virtual OLT hardware abstraction component that supports the CORD Project objective of multi-vendor, multi-domain "any broadband access as a service" reference implementation for the Central Office. VOLTHA provides isolation between an abstract (vendor agnostic) PON management system, and a set of vendor-specific and white-box PON hardware devices. On its north-bound interface, VOLTHA provides a set of abstract APIs which north-bound systems can interact with the PON networks.  On its south-bound side, VOLTHA communicates with PON hardware devices using vendor-specific protocols and protocol extensions through adapters.


Key People and Communication Channels

Technical Steering Team

The technical steering team is responsible for all technical decisions in the project. They are responsible for the content and structure of the code base and for all technical priorities with respect to the code base.

Lists

The mailing lists are the preferred way to get in touch with the project members with any questions, suggestions, or concerns.

Slack

The CORD Slack is the best way to get quick answers to your questions. Our team is distributed globally, so someone should be available at all times. vOLTHA topics are discussed in the #voltha channel.

Brigades

Interested in contributing to VOLTHA? Some of the tools we use require you to register for the overarching CORD project, so we suggest you register first and then dig into the rest of the information, starting with the Contributing to CORD documentation.

Here are the key tools we use: 

  • VOLTHA JIRA Project - Project here
  • VOLTHA GitHub - here 
  • Olf test suite for OLT functionality: https://gerrit.onosproject.org/#/admin/projects/olt-oftest
  • VOLTHA 2.x Roadmap and Release Planning

    VOLTHA work is done primarily using the brigade structure. Current brigades:

    Release and Project Management

    Working as an open source community team

    • The intended host of this project is the CORD project (opencord.org).
    • All source code to be developed via the gerrit system of opencord.
    • All parts of VOLTHA will be managed as one git repository (any proprietary plugin code by vendors will be kept in separate repos/places).
    • All project documentation must be kept with the git repository (preferably as markdown (*.md) files, with drawings created with preferably Inkscape (has to be editable and PNGs can be redesigned).
    • All major changes, decisions, etc., must be done with VOLTHA TST approvals, and pursuant of the CORD project governance rules.

    VOLTHA Release Acceleration

    • Agile + Continuous Integration - Mandatory Test Driven Development
    • Single source code repo with automated build
    • Transparency - Everyone should know what is going on
    • Design Specs for all major new features - get the team engaged for cross functional support on features (dev, test, doc etc)
    • WIKI is the main source of true for documentation, not google docs
    • All contributions upstream tracked in JIRA and linked to Gerrit
    • Keep JIRA up-to-date to avoid duplication of efforts or gaps in sprint deliverables

    Release Model and Cadence

    VOLTHA will follow the CORD release model, branching, versioning and tagging best practices found here: Release Management

    Election Process

    The 2019 election process has two main steps for all positions. Nomination, and voting.

    When there is only one nomination for a position, there does not need to be a vote.

    Voting Community

    The voting community is composed of the following people:

    • Steering team members and leads
    • Contributors (those who have submitted code which has been reviewed and accepted in the last year)
