Internet protocol version 6 (IPv6) promises to deliver connectivity features in Windows Vista not possible with today's Internet protocol version 4 (IPv4).
Sinead O'Donovan, product unit manger for networking at Microsoft, said "When we looked at key applications such as MSN Messenger, we learned that developers needed to do too many tricks to get them to work over NAT." more»
From a notorious striptease by Internet pioneer Vint Cerf to a fist-pumping, table-jumping brawl about cryptography policy, the Internet's premier standards-setting body has had its share of big moments. This week, the IETF celebrates another one when it turns 20. The IETF is an egalitarian, all-volunteer group consisting of network engineers from Cisco, IBM, Microsoft, AT&T and other leading vendors. It has created many of the underlying standards that make the Internet work, including fundamental routing, e-mail, directory services and telephony protocols. 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»
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»
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»
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»
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»
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»
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»
The US Federal Communications Commission (FCC) recently issued a public notice that it will be holding two workshops on the transition of the public switched telephone network (PSTN) to "new technologies" such as voice-over-IP (VoIP). The workshops will be held on December 6 and 14, 2011, at the FCC's office in Washington, DC. The public notice states the goal as... 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»
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»
"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»
Doug Madory reporting in Renesys Blog: "Packet latency is a big issue in Internet-based applications (i.e. the stuff in the cloud). In conducting analysis on Internet infrastructure over the years, we have seen many patterns of connectivity. One such pattern that can wreak havoc on latency is 'hair-pinning', a phenomenon where traffic takes an unnecessarily long physical path between two points on the Internet due to suboptimal routing. The increased distance results in increased latency, and the 'lag' or 'sluggishness' that users experience as a result can hinder latency-sensitive online applications whether they are financial trading applications or MS SharePoint." more»
