Speech at the Internet Governance Principles panel at ICANN 49, Friday 21st March, 2014, Singapore. I wanted to approach the panel's topic from the angle of the people in the organisation that I work with, the Internet Engineering Task Force or the IETF. I will first talk about our general engineering angle on Internet governance, and then continue about the specific and current hot topic of IANA evolution. The engineers, and the IETF, obviously care a lot about the Internet. That it works well, and that all aspects of managing it are done carefully, with sufficient knowledge, and with stability and growth of the Internet in mind. We realize of course that there are multiple topics in the area of Internet governance, and some are further away from us than others. As an example, we care about names and addresses, but their management is the daily task of other organizations. Whereas protocol parameters - such as port number allocations - are something that we directly depend on. Some of the key principles for any work that we do include open participation, getting input from different parties, and broad consensus on decisions. A natural fit for the multi-stakeholder model. And as engineers we obviously care a lot about the technical aspects. Solutions should provide global interoperability and scalability. Technical merit and implementability matters. These need to be taken into account even in Internet governance. But we also like our technology to serve as building blocks for further innovation. We sometimes talk about the concept of permissionless innovation that is behind so many successes in the Internet. What this concept implies is that users and developers have an ability to create their own innovations on top of generally usable technology. And the technology largely allows that. This has also interesting implications for Internet governance. For instance, new identifier spaces are created all the time, just witness hash tags or social media nicknames and the like. The Internet evolves fast. Finally, I wanted to get back to the more specific question of IANA evolution, and particularly the protocol parameters aspect. Our role in that space relates to setting the allocation policies and ensuring their faithful registry implementation. Working together with IANA. Earlier this month the IAB held a session in our meeting to discuss the principles regarding IANA evolution from our perspective. I wanted to highlight a couple of the results. First, I want to make the observation that IANA functions have evolved over time. In the last decade, the IETF and IANA have seen the creation of MoUs, SLAs, role definition RFCs, and groups to track the relationship. Not to mention 1000s of RFCs on protocol parameter allocation policies. Second, the process recently started by NTIA is just another step in that evolution. And I think that step is well justified, given IAB view, supported by the community, that the protocol parameter registry function as being and continuing to be capably provided by the Internet technical community, without the need for external parties. Third, I wanted to observe that we consider the protocol parameters work a big success. Everything is running very well, we are happy with the services provided by the IANA function, and we keep making continuous improvements. I would like to offer that this operating model is a good basis in many situations. That is, we have agreements in place for the function to be performed, there are specifications about how the process should work, and there are boards that are accountable to the specific parts of the efforts on both sides.
