THE LINUX FOUNDATION PROJECTS
Tunnel Background

PROJECT CHARTER

1. Mission of the Data Plane Development Kit

The mission of DPDK is to:

  1. Create an open source, production quality, vendor neutral software platform for enabling fast packet processing, upon which users can build and run data plane applications.
  2. Host the infrastructure for the DPDK community, establishing a neutral home for community assets, meetings, events and collaborative discussions.
2. Project Structure

The DPDK Project is composed of software, a community lab (development infrastructure), and marketing activities.

2.1 Software

The DPDK Project software is composed of one core software project which is DPDK itself, and a few hosted projects that are closely related to DPDK.

The core DPDK project is comprised of a number of git repositories, including a master repository, several “next” repositories which are used to apply changes to specific parts of DPDK before these are pulled into the master repository, and a stable release repository. This structure is listed in the repository home page.

The hosted projects that are also hosted as part of the DPDK Project are typically applications that are closely related to DPDK. These are called “hosted projects” and can be browsed in the repository home page.

Changes to this software structure, including approval for any new hosted projects, are the responsibility of the Technical Board (see clause 3.2 below).

2.2 Community Lab

The DPDK Community Lab provides the project’s physical infrastructure for a test harness and software in support of the project’s software development, testing, and release processes.

2.3 Marketing Activities

Marketing activities include planning, creating and executing community events, content (including but not limited to blogs, whitepapers, social media posts, and testimonials), external communications, and media relations. The marketing activities define the public persona of the project.

3. Project Governance

Governance of the DPDK project is followed through the following boards:

  1. A Governing Board which has ownership and oversight on budget, marketing, lab resources, administrative, legal, and licensing issues.
  2. A Technical Board which has ownership and oversight on technical issues including approval of new hosted projects, deprecating old hosted projects, the project’s technical roadmap, recruiting maintainers, defining the processes for contributing, testing, and managing security, defining criteria and a process for event technical content, and resolution of technical disputes.

These two boards are peers and work together to oversee the DPDK project.

3.1. Governing Board3.1.1. Scope

The Governing Board covers the full scope of DPDK, including all hosted projects. Responsibilities of the Governing Board are:

  1. Electing a Chair to preside over meetings, authorize expenditures approved by the Governing Board, and manage day-to-day operations.
    1. The Chair will be elected on an annual basis.
    2. The existing Chair will be allowed to stand for re-election
  2. Electing a Vice Chair to support the Chair as needed in presiding over meetings, authorizing expenditures approved by the Governing Board, and managing day-to-day operations
    1. The Vice Chair will be elected on an annual basis.
    2. The existing Vice Chair will be allowed to stand for re-election.
  3. Electing a Treasurer to assist in the preparation of budgets for Governing Board approval, monitor expenses against the budget and authorize expenditures approved in the budget, and work with the Linux Foundation to maintain current sponsorship levels. As schedule permits, the treasurer may also elect to work to secure new project sponsors.
    1. The Treasurer will be elected on an annual basis.
    2. The existing Treasurer will be allowed to stand for re-election.
  4. Overseeing all project business and marketing matters including planning and executing DPDK events.

  11. Voting on all matters requiring a decision from the Governing Board.
3.1.2. Composition

The Governing Board shall consist of:

  1. One representative appointed by each Gold Member as specified in clause 4.iv.i below.
  2. Up to two Silver Member representatives as specified in clause 4.v.i below.
  3. One representative of the Technical Board, to be rotated through by Technical Board members, approximately quarterly.
3.1.3. Conduct

Conduct of Governing Board meetings:

  1. Governing Board meetings shall be limited to the Governing Board representatives, plus any other individuals that the Governing Board invites because their input is required on specific agenda topics. The Governing Board will allow a named representative to attend as an alternate if a Governing Board member cannot attend.
  2. The quorum required for a meeting to proceed is a majority (> 50%) of the Governing Board.
  3. For a vote to be passed on the following items, a ⅔ majority (> 66%) of the total Governing Board is required (not just a ⅔ majority of those in attendance at the meeting). In the event of a deadlock the Governing Board Chair shall cast the deciding vote.

    2. Approval of any changes to this Charter document (see clause 12).

  5. The Governing Board will encourage transparency, including the publication to the community of summary meeting minutes and reporting of budgets within a reasonable time following their approval by the Governing Board. When approving meeting minutes and budgets, the Governing Board must approve any items which cannot be included in the public versions for confidentiality reasons.
    Note: Examples of board discussions which should not be made public might include things like legal issues, confidential budget discussions, discussion on potential new project members that have not yet been made public, etc.
3.2 Technical Board3.2.1. Scope

The Technical Board is responsible for technical decision making for the DPDK project. Its scope does not include the other dpdk.org’s hosted projects (e.g. Pktgen, SPP etc.). A separate Technical Board may be established for other hosted projects in the future if any of them grows sufficiently large to require one.

Responsibilities of the Technical Board are:

Electing a Chair to preside over meetings, and manage any day-to-day operations. The Chair may be appointed on a rotating basis.

  1. Approving any new hosted projects, including new “next” repositories for DPDK and new DPDK-based apps like Pktgen and SPP. The procedure and requirements for requesting a new hosted project will be defined by the Technical Board. The Technical Board will apply non-technical criteria for new hosted projects that are defined by the Governing Board (see clause 3.1.1.ix) when making its decision on proposed new projects. Requests can be submitted by emailing techboard@dpdk.org.
  2. Deprecating any existing hosted projects. The procedure for deprecation and archival is defined by the Technical Board. Deprecation requests can be submitted by emailing techboard@dpdk.org.
  3. Resolving any technical disputes. Anybody who is unhappy with the resolution of a technical issue can request that the Technical Board review the issue and make a decision on it by emailing techboard@dpdk.org. This is only expected to happen in exceptional cases. Before escalating to the Technical Board it is required that all reasonable steps to resolve the dispute via consensus are taken and recorded on the dev@dpdk.org mailing list. If the Technical Board Chair does not feel that this has happened, they can refer the issue back to the complainant for further action to be taken before escalating it to the Technical Board.
    The decision of the Technical Board on any technical disputes will be final and all project contributors are expected to comply. If a Maintainer or Committer fails to comply with a decision of the Technical Board, the Technical Board will be empowered to take any necessary steps to enforce its decision, including replacing that Maintainer/Committer.
    Note: Examples of issues that fall into this category might include disagreements over which patches should/should not go into DPDK.
  4. Voting on all matters requiring a decision from the Technical Board.
