In my previous blog on the topic, I stated that the business case supporting the IPv4 roll-out in the late 90s was the Internet. Although IP depletion will slowly become a reality, the chances are that due to mitigating technologies such as NAT and DNS64, it may take quite a while before organizations in the developed economies will get serious about IPv6. So where should we look to find a business case for IPv6? more

When discussing IPv6, it is easy to forget that we are ultimately talking about an enhanced version of an existing network protocol. Sure, it brings about a number of technical advantages. But when viewed in isolation - without a business case - there really are not that many drivers that would place IPv6 on the agenda of the top decision makers looking after budgets. For IPv6 to gain serious momentum, this has to be changed. more

While a great deal of attention has recently been paid to the enormous amount of change that is taking place at the edge of the network with smartphones, tablets, apps, Web2.0 etc, massive changes are also underway on the network side. The current network has been designed over a period of thirty years and it is due for a serious overhaul to keep abreast of changes in the industry in general. more

No, that title is not a typo. The WHOIS service and the underlying protocol are a relic of another Internet age and need to be replaced. At the recent ICANN 43 conference in Costa Rica, WHOIS was on just about every meeting agenda because of two reasons. First, the Security and Stability Advisory Committee put out SAC 051 which called for a replacement WHOIS protocol and at ICANN 43, there was a panel discussion on such a replacement. The second reason was the draft report from the WHOIS Policy Review Team. more

Another twenty five years has just zoomed by, and before you know it, it's all on again. The last time the global communications sector did this was at the WATTC in 1988, when "the Internet" was just a relatively obscure experiment in protocol engineering for data communications. At that time the Rather Grand telephone industry bought their respective government representatives... to the Rather Grandly titled "World Administrative Telegraph and Telephone Conference (WATTC) in November 1988 in Melbourne, Australia and resolved to agree to the Rather Grandly titled "International Telecommunication Regulations." more

"Internet protocols simply aren't adequate for the changes in hardware and network use that will come up in a decade or so," says Professor Dave Farber who was recently interviewed by Andy Oram. "Dave predicts that computers will be equipped with optical connections instead of pins for networking, and the volume of data transmitted will overwhelm routers, which at best have mixed optical/electrical switching," writes Oram. more

As part of its efforts to speed up the delivery of web content, Google has proposed changes to Transmission Control Protocol (TCP), "the workhorse of the Internet." Yuchung Cheng who works on the transport layer at Google wrties: "To deliver content effectively, Web browsers typically open several dozen parallel TCP connections ahead of making actual requests. This strategy overcomes inherent TCP limitations but results in high latency in many situations and is not scalable. Our research shows that the key to reducing latency is saving round trips. We’re experimenting with several improvements to TCP." more

An interesting new paper from the Naval Postgraduate School describes what appears to be an interesting new twist on spam filtering, looking at the characteristics of the TCP session through which the mail is delivered. They observe that bots typically live on cable or DSL connections with slow congested upstreams. ... This paper tries to see whether it would be practical to use that info to manage spam in real time. more

I am a big fan of DDI (DNS, DHCP and IPAM) as magical trio to manage all transactions on network infrastructures... Or to say the least: make it possible. Basically it makes these "Core Network Services" concise, manageable and integrated. It basically makes the network infrastructures of today and the future possible. There is however one thing that continuously seems to irritate when talking about integrating these services on networks. more

In a move to be celebrated by many of us with a VoIP background, the United States Federal Communications Commission (FCC) announced today the appointment of Henning Schulzrinne as Chief Technology Officer (CTO). As the release indicates, Henning's role as CTO will be to: ...guide the FCC's work on technology and engineering issues, together with the FCC's Office of Engineering and Technology. more
