Running Code

There was an interesting discussion in a working group session at the recent IETF 111 meeting over a proposal that this working group should require at least two implementations (presumably independently developed implementations) of a working group draft before the working group would consider the document ready for submission to…


Some not-DNS Topics at IETF 111

I’ve already scribed my thoughts on the DNS-related topics that were discussed at the July 2021 IETF 111 meeting. It may be surprising to the DNSphiles out there but there really are other topics that are discussed at IETF meetings not directly related to the DNS! These are some notes…


DNS at IETF 111

IETF 111 was held virtually in July 2020. These are some notes I took on the topic of current activities in the area of the Domain Name System and its continuing refinement at IETF 111. DNSOP – DNS Operations DNSOP is the general working group for most DNS topics and…


DNS at IETF 110

IETF 110 was held virtually in March 2020. These are some notes I took on the topic of current activities in the area of the Domain Name System and its continuing refinement at IETF 110. The amount of activity in the DNS in the IETF seems to be growing every…


TCP Congestion Control at IETF 110

IETF 110 was held virtually in March 2020. These are some notes I took on the topic of current research activities in the area of transport protocol flow control at the meeting of the Internet Congestion Control Research Group at that meeting. HPCC+: High Precision Congestion Control In the early…


IETF 109

For a group that works on network technologies it was always a bit odd that the IETF met in person three times a year. Didn’t we have enough trust in the efficacy in the technologies that we work on? I don’t think that is the case. I think the bandwidth…


My IETF 106

The 106th meeting of the IETF was in Singapore in November 2019. As usual for the IETF, there were many Working Group meetings, and this report is definitely not an attempt to cover all of these meetings or even anything close to that. Here I’ve been highly selective and picked…


Network Protocols and their Use

In June I participated in a workshop, organized by the Internet Architecture Board, on the topic of protocol design and effect, looking at the differences between initial design expectations and deployment realities. These are my impressions of the discussions that took place at this workshop. 1 – Case Studies In…


Just One Bit

I’m never surprised by the ability of an IETF Working Group to obsess over what to any outside observer would appear to be a completely trivial matter. Even so, I was impressed to see a large-scale discussion emerge over a single bit in a transport protocol being standardized by the…
