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
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
Today, December 14, 2011, the US Federal Communications Commission (FCC) is holding the second of two workshops on the transition of the PSTN to new technologies. The workshop started streaming live this morning at 9:30am US Eastern. The FCC's note about the workshops mentions that people watching the live stream can send in questions to panelists using either of two methods... more
If you missed attending or listening to the live stream of the US Federal Communication Commission's (FCC) workshop on the transition of the Public Switched Telephone Network (PSTN) to new technologies that was held last week on December 6th, the FCC has very nicely made a video recording available from their website for viewing... FCC Chairman Julius Genachowski also appeared briefly to provide a few comments. more
While it would be nice if your company had IT staff members that were experts in every technology, that is just not realistic. And today, many companies face the challenge of finding the appropriate and specialized expertise that is required to deal with ongoing issues such as network optimization, performance degradations, network risks, and more. more
Geoff Huston, APNIC's Chief Scientist, is visiting the RIPE NCC this week to spend time with his fellow Regional Internet Registries (RIR) colleagues and to strengthen collaboration on shared projects. We've used this opportunity to invite him to produce the 'Interesting Graph of the Week'. Geoff has been monitoring the global routing system for many years. Here are his most recent observations. more
There are only a few occasions in any of our lifetimes where what we know and have grown used to is turned on its head. We have now lost the generation that heard radio for the first time; there are only a few who can recall the first television pictures; but many, many more saw color appear on their screens for the first time. more
With the recent passing of Paul Baran, IFTF is releasing an excerpt of a 1971 report in tribute, entitled "Brief descriptions of potential home information services." The excerpts are from the report titled, Toward a Study of Future Urban High-Capacity Telecommunications Systems, which included a handbook of forecasts for what was then called "broadband telecommunication and information services," later known as the Internet. more
The importance of online presence continues to grow exponentially. More and more of our personal and professional endeavors are conducted online. Because of this, the ability to ensure a good experience for our online friends and customers also is increasing rapidly. At its core, load testing is nothing more than ensuring your online presence is ready for the number of visitors you expect. It's simple to explain, but historically it's been anything but simple, or easy to afford. more
According to IDC, smartphones outsold personal computers, laptops included in Q4 2010! Nokia just announced the demise of the Venerable Symbian in favour of Windows 7 phone and Microsoft's bing search engine! Tectonic shifts are under way to adapt to the rise of wireless broadband, an all IP world, and the growing weight of Apple and Google Android. It is also time to head once again for Barcelona with the Mobile World Congress starting on the 14th. Highlights this year? more
