Contributor Onboarding

For new contributors, the following should be helpful to get up to speed quickly and contribute to the project.


Discussions around OpenSwitch development are held in two places:

  • The openswitch-dev mailing list.
  • The #openswitch channel on Freenode.

New contributors should be sure to subscribe to the mailing list and to add #openswitch to their IRC client. To join the mailing list, go to and follow the instructions to join the mailing list “openswitch-dev” there. To join Freenode, select an IRC client for your operating system, join Freenode, and ensure you add the #openswitch channel to your list of channels. Webchat is a good system for those new to IRC who want to quickly get up and running with IRC.

Licensing of Contributions

OpenSwitch uses a combination of the standard Developer Certificate of Origin (DCO) and a Contributor License Agreement (CLA) for all contributions. The dual-stacked approach allows for the following:

  • Corporate entities must execute the corporate CLA before their employees may contribute.
  • Everyone submitting code adds the (DCO) to their commits.

The CCLA text can be found in the appropriate documents.

The exact text for the DCO used by OpenSwitch is as follows:

Developer's Certificate of Origin 1.1

By making a contribution to this project, I certify that:

(a) The contribution was created in whole or in part by me and I
    have the right to submit it under the open source license
    indicated in the file; or

(b) The contribution is based upon previous work that, to the best
    of my knowledge, is covered under an appropriate open source
    license and I have the right under that license to submit that
    work with modifications, whether created in whole or in part
    by me, under the same open source license (unless I am
    permitted to submit under a different license), as indicated
    in the file; or

(c) The contribution was provided directly to me by some other
    person who certified (a), (b) or (c) and I have not modified

(d) I understand and agree that this project and the contribution
    are public and that a record of the contribution (including all
    personal information I submit with it, including my sign-off) is
    maintained indefinitely and may be redistributed consistent with
    this project or the open source license(s) involved.

Please note code commits will not include the DCO text above, but rather the standard “Signed-Off-By” line. The above is meant to replicate the text a contributor is agreeing to by adding their “Signed-Off-By” to each commit.

IRC Information and Etiquette

The main IRC channel for OpenSwitch is #openswitch on Freenode. Sub projects may utilize additional channels, and they should be added below as they are created and used for OpenSwitch development.

Please note the #openswitch IRC channel is logged publicly.

Weekly Meetings

OpenSwitch holds a weekly IRC meeting. This meeting is held on Freenode in the #openswitch channel. The meeting is held at 1700 UTC on Wednesdays. Please note the OpenSwitch meeting follows UTC and not DST.
