The IPv6 protocol introduced very few changes to its IPv4 predecessor. The major change was of course the expansion of the size of the IP source and destination address fields in the packet header from 32-bits to 128-bits. There were, however, some other changes that apparently were intended to subtly…
After pulling out the notes from the IEPG meeting and aspects of the DNS, here are the rest of the items that I personally found to be of interest at IETF 99 last week. IPv6 Operations – Apple’s Happier Eyeballs? The way in which browsers leverage the potential opportunities offered…
Interest in the DNS appears to come in waves. It’s quiet for a few years, then there is a furious burst of activity. We appear to be in the middle of a burst of activity, and there is probably enough material presented at the recent IETF meeting to cover the…
It’s hard to classify the IEPG meetings that occur at the start of the IETF week. Many years ago they had a role in allowing network operators to talk to other operators about what they were seeing and what they were thinking about. Those days are long since over, and…
The Border Gateway Protocol (BGP) is the routing protocol that literally keeps the Internet glued together. The public Internet is composed of some 58,000 component networks (BGP calls them “Autonomous Systems” (AS’s)), many of which are very small, while some are very large both in terms of geographical coverage and…
OARC 26 was held in May in Madrid. Here are my impressions of the meeting, drawn from some presentations that I found to be of personal interest. All the presentations can be found at OARC’s web site.
RIPE 74 was held in May in Budapest, and as usual it was a meeting that mixed a diverse set of conversations and topics into a very busy week. Here are my impressions of the meeting drawn from a number of presentations that I found to be of personal interest.…
The Internet was built using an architectural principle of a simple network and agile edges. The basic approach was to assume that the network is a simple collection of buffered switches and circuits. As packets traverse the network they are effectively passed from switch to switch. The switch selects the…
The IETF meetings are relatively packed events lasting over a week, and it’s just not possible to attend every session. Inevitably each attendee follows their own interests and participates in Working Group sessions that are relevant and interesting to them. I do much the same when I attend IETF meetings.…
Having just spent two and a half days at an ARIN Public Policy Meeting, I’d like to share some of my impressions of the meeting, and the state of address policy in the region served by ARIN. It’s clear that ARIN has largely undertaken its mission with careful and considered…
