Governance of the ONOS™ project is a hybrid. It attempts to take what has worked well for open source projects and leave out what didn’t work so well. Mostly, it is governed as a technical meritocracy – those who contribute the most have the most influence on the technical direction and decisions. There is also an element of benevolent stewardship. This is what gives the project its strong vision, goals, and technical shepherding. More specifically, ONOS governance is


The ONOS project is governed by four teams and a board of advisorsof directors. The four teams are the technical steering team, the use case team, the release management team, and the community team. ONOS subprojects are formed as part of one of the four teams.


The Chairman of the Board is chosen by the Open Networking Laboratory Board of Directors. Each organization is responsible for nominating their board member. The chairman of the board must approve the nomination. Board members are (re) elected nominated/approved every year. Elections Nominations/approvals are held in the first quarter of each calendar year. If any board member must leave before the end of their term, their organization will nominate a new member and that member must be approved by the Chairman of the Board. If the Chairman of the Board must step down, then the ON.Lab Board of Directors will select a new Chairman.

2016 Elections Process and Information can be found here.


There are three classes of voting: ON.Lab, Vendors and Service Providers. Each receives votes according to the following allocation of 100 votes. Votes may be fractional.


The technical steering team is responsible for all technical decisions having to do with the ONOS core codebase. The ONOS core codebase is the software distribution represented by the ONOS trademark. Use case applications, southbound plug-ins for non-OpenFlow devices, sample applications, vendor proprietary extensions may or may not be part of the ONOS core. It is entirely up to the technical steering team to decide what constitutes the ONOS core codebase.
