6. Technical Discussion: Different or Same, IP for Internet and Limited Domain

Zhenbin Li delivered a presentation on “Same or Different: IP for Limited Domain and Internet.”

Zhenbin Li said that there are always new innovations based on the argument that the Internet does not work well. In fact, the some IP technologies may only be used in the limited domains and still cannot change resources in the Internet infrastructure like IP address, domain name, AS number, etc.

So Zhenbin Li asked whether the Internet should be divided into Internet vs. Limited Domains or not?

RFC 8799, “Limited Domains and Internet Protocols,” discusses trends around limited domains. Zhenbin Li asked what else can be done; should there be a new document to record the conflict and current thinking, or perhaps a workshop to explore this further?

Russ White said that he thinks it is important to think through the differentiation between local scope and global scope, and agreed that this is an important area for the IAB to think about. He noted this might be relevant to the proposed IDR workshop.

Lars Eggert said that limited domains are being used as a solution to some of the harder Internet problems, but eventually people will want to stitch these limited domains back together into something that resembles the Internet, only using technologies that aren’t designed for that. Lars said that he would prefer to focus on the global Internet; people bring work to the IETF because they want standards and interoperability that is broader than limited domain.

Warren Kumari agreed, saying that many people who cite RFC 8799 think they do not need to worry about security or operational issues, but that is not what the document says.

Éric Vyncke said that there are a few things that will never leave the local domain, but that interoperability is important; it is the reason why enterprises come to the IETF for standardization.

Jari Arkko said he agrees with Lars Eggert, and that the IETF should focus on making the global Internet work correctly rather than focusing on local domains. He noted, however, that a feature of the Internet architecture has always been to allow customization locally. If the local solution needs too much information from the application, then you might have a solution that does not work across a bigger domain. Jari added that the security model has changed, and that the notion that a limited domain is under your control is old fashioned.

Deborah Brungard said that many people misinterpret RFC 8799, but that we should also remember that it was an Independent Submission and does not have IETF consensus. It should be very clear if a protocol is to be for a limited domain.

Zhenbin Li agreed that the IETF should work on technologies for the global Internet, but noted that data center networks are a special case. The operators depend on the vendors for the functionality, and they need interoperability between different vendors. Zhenbin thanked everyone and said he looked forward to continuing the discussion in the future.
