Do "smart" parking meters really need phone numbers? Does every "smart meter" installed by electric utilities need a telephone number? Does every new car with a built-in navigation system need a phone number? Does every Amazon Kindle (and similar e-readers) really need its own phone number? In the absence of an alternative identifier, the answer seems to be a resounding "yes" to all of the above. more»
Do you know of a person or organization who has made a great contribution to the Internet community? If so, have you considered nominating that person or organization for the 2013 Jonathan B. Postel Service Award? The nomination deadline of May 31 is fast approaching! more»
Following up on my recent post about how solving the Bufferbloat problem could dramatically increase the speed of Internet usage, I recently learned via a Google+ post by Michael Richardson of this video of a presentation by Jesper Dangaard Brouer of Red Hat at the recent DevConf.cz Brno 2013 titled "Beyond the existences of Bufferbloat - Have we found the cure?" more»
Could you sign off of the Internet today -- right now, in fact -- and not come back online for 12 months? If you are a reader of CircleID, odds are pretty good that the answer is probably an emphatic "No!" This is, after all, a site for "Internet Infrastructure" and for most of us visiting the site (or writing here) the "Internet" is completely woven into the fabric of our lives... and we have a hard time thinking of a life without it. more»
Of all the many applications and services that run on top of the Internet, arguably none has been more successful than that of the World Wide Web. Invented by Tim Berners-Lee back in 1989 while he was a physicist at CERN, the "Web" has fundamentally changed almost every aspect of our life... and become a part of basically every aspect of our life. Think of a part of your life... and then think of the websites that are part of that. more»
Tonight begins the third annual SIP Network Operators Conference (SIPNOC) in Herndon, Virginia, where technical and operations staff from service providers around the world with gather to share information and learn about the latest trends in IP communications services - and specifically those based on the Session Initiation Protocol (SIP). Produced by the nonprofit SIP Forum, SIPNOC is an educational event sharing best practices, deployment information and technology updates. Attendees range from many traditional telecom carriers to newer VoIP-focused service providers and application developers. more»
What if there was a relatively simple fix that could be applied to home WiFi routers, cable modems and other gateway devices that would dramatically speed up the Internet access through those devices? Many of us may have heard of the "bufferbloat" issue where buffering of packets causes latency and slower Internet connectivity, but at IETF 86 last month in Orlando I got a chance to see the problem with an excellent demonstration by Dave Täht as part of the "Bits-And-Bytes" session. more»
If you are interested in the current state of IPv4 address exhaustion within North America as well as the current state of IPv6 deployment, there will be a live stream today, April 17, of the sessions happening at INET Denver starting at 1:00pm US Mountain Daylight Time (UTC-6). The event is subtitled "IPv4 Exhaustion and the Path to IPv6" and you can view the live stream at. more»
One of the staggering numbers introduced during the opening remarks at ICANN 46 here in Beijing by multiple speakers, including ICANN CEO Fadi Chehade and speakers from the Chinese government, was this: China now has over 564 million Internet users! Think about that for a minute. more»
The 46th meeting of the Internet Corporation for Assigned Names and Numbers (ICANN) takes place this week in Beijing, China, and will bring together leaders from all over the world to discuss and debate a wide range of issues related to domain names and the surrounding industry. One can expect that the new gTLDs, a topic frequently discussed here on CircleID, will naturally consume a great amount of the discussion at ICANN 46. more»
How will the business of existing top-level domains (TLDs) be impacted by the new gTLDs? Someone asked me this simple question and I was very surprised to see that my online searches couldn't easily find many detailed articles or research related to that point. more»
For those of you interested in IPv6 and/or DNSSEC, we'll have a live webcast out of the Internet Society's ION Singapore conference happening tomorrow, March 28, 2013, starting at 2:00pm Singapore time. more»
As much as we talk here about the inner workings of the Internet's infrastructure, there are times when you have to just sit back and look at how incredibly cool some of the things are that are enabled by the Internet. For example, last week I was delighted to stumble across this excellent music video collaboration between the International Space Station's Canadian commander Chris Hadfield, the Canadian band Barenaked Ladies along with a Canadian student choir. more»
It was 30 years ago today, on January 1, 1983, that the ARPANET had a "flag day" when all connected systems switched from using the Network Control Protocol (NCP) to the protocols known as TCP/IP. This, then, gave rise to the network we now know as the Internet. more»
If any of you are attending the USENIX Large Installation System Administration (LISA) conference in San Diego this week, the Internet Society's "Internet ON" (ION) Conference is co-located with LISA12 and will take place tomorrow, December 11, 2012, from 1:30 - 5:00 pm US Pacific time. more»
This morning brought word that all Internet connections into Syria had been severed. Internet monitoring firm Renesys was among the first to report the news in a blog post that they have continued to update. That news was subsequently confirmed by other sites and services... Multiple reports indicate that all Internet, cell phone and landline connections to all or most of the country have been severed. more»
The Seventh Annual Internet Governance Forum (IGF) is underway now in Baku, Azerbaijan, from November 6-9, 2012. Very appropriately, it is possible to listen in to any of the sessions remotely across the Internet. Details can be found here... more»
The 85th meeting of the Internet Engineering Task Force (IETF) begins next week in Atlanta, Georgia, USA. Over 1000 engineers, maybe as many as 1400 or more, from all around the world will gather in various working groups to discuss and debate issues relating to the open standards that define the Internet's infrastructure. more»
As we start moving more real-time communications into web browsers with the upcoming WebRTC/RTCWEB offerings, what do we do about congestion control? How do we ensure that all these browser-based communications sessions share the network fairly? With RTC capabilities now already available in builds for browsers such as Google Chrome and Mozilla Firefox, how do we deal with the expected increase in voice, video, chat and data traffic? more»
No more "test flights" ... 2012 is the year that IPv6 gets permanently deployed! That is the message of "World IPv6 Launch," announced today by the Internet Society, Google, Facebook, Cisco, Microsoft, Comcast, AT&T, Time Warner Cable and a whole host of other companies. While last year's successful World IPv6 Day was all about testing how your site or service worked with IPv6, this year's World IPv6 Launch is about enabling IPv6 permanently as of June 6, 2012 (or earlier). more»
What kind of IPv6 support will we see in consumer devices at the massive Consumer Electronics Show (CES) happening in Las Vegas this week? The show is already underway and much of the tech media is already writing in breathless prose about the latest tablets, notebooks and zillions of other consumer devices making their debut at CES. While the bright-shiny-object-chasing side of me definitely notices those articles, my own interest is on a deeper and far more technical level. 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»
With IPv4 address exhaustion upon us, it appears that the going market rate for IPv4 addresses is now $12/address. Over at the Register, Kevin Murphy reports on a bankruptcy filing from Borders seeking to sell a /16 block of to healthcare software vendor Cerner for a total of $786,432. At $12 per IPv4 address, this sets a new public record given that the previous high was Microsoft's acquisition of a block of Nortel IPv4 addresses... 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»
Fascinating stats out of an article at TheNextWeb this week: China has become the first country to reach the 900 million mobile phone user milestone after amassing about 11 million mobile phone users in April alone, according to a report by the country's Ministry of Industry and Information Technology. more»
Before writing my story yesterday about Skype killing off Skype For Asterisk, I had reached out to Skype's PR agency to see if there was any statement from Skype. There wasn't at the time, but today they sent over this statement from Jennifer Caukin, a spokeswoman for Skype... more»
And so it ends... Skype was always always a fun company to write about because they were always a bit of a rogue. The scrappy little startup that took on the megacorps of the telecom industry... and won in so many ways... look at their leading % of international calls... or the fact that per-minute call costs are now very clearly being commoditized down to zero... more»
It's been a busy month for the folks in the Skype For SIP project. First, back on September 9, Skype announced ShoreTel interoperability. Then last week on September 17, Skype announced interop with the open source SIPFoundry sipXecs product. Today, though, is Skype's biggest announcement yet... more»
Is the new ".tel" domain launching today more than just a pretty web interface to DNS? Is it something really unique? Is it a new service that couldn't be easily replicated elsewhere? In case you haven't been following the subject, a company called Telnic has launched a new top-level DNS domain ".tel" today. Today, December 3rd, is the launch of the "Sunrise" period where companies can (for a high price) obtain the ".tel" domain associated with their trademark. more»
Do you care any more about zillion different IM services? Do you care about the IM protocol wars that have plagued the usage of IM for the last years? Odds are that if you are an IM user like me, you probably don't. Why not? Simple... we've unified the IM services on the client side and basically stopped caring about the various services and protocols. I was reminded of this fact this morning when I received a message saying that an update was available for Adium on my Mac that solved a really annoying disconnection problem with Yahoo!Messenger. more»
Does "voice" communication really matter as much today in business communications? Think about it. When you need to reach someone today, what do you do? Do you call them on the phone? Or do you send them email? Or a text message? or IM? I know personally that my normal communication flow usually goes something like this: Instant Messaging; I check first to see if I can reach the person on some form of IM... SMS; if the matter is relatively important... E-mail/Facebook/Twitter/other; Previously that would have just been email, but these days I find myself very often sending messages via Facebook or Twitter... more»
News breaking out today is that Google has acquired GrandCentral for something around $50 million. GrandCentral is a service that gives you one phone number that can ring multiple numbers, provide one common voicemail - and all sorts of the other features (see "howitworks" for a list of features)... So will we ultimately see voicemail inside of Gmail? One would assume that we will eventually see integration with GoogleTalk... more»
NetworkWorld is running an article today that talks about the announcement from ARIN (the American Registry for Internet Numbers) of the ARIN Board resolution calling upon ARIN to no longer be "neutral" in the IPv4 vs IPv6 space and instead work to actively encourage migration to IPv6... Until now, ARIN and the other RIRs have generally been fairly neutral in the IPv4 versus IPv6 debate and have not shown a preference in allocation, but this announcement from ARIN shows the first signs of change. more»
Since Skype has an open client-side API, why not use it as a transport to tunnel VPN traffic and blow through firewalls to connect you to a remote system? That's the idea raised by Peeter P. Mõtsküla in his Skype Developer Blog entry: "Idea: skypetunnel". For instance, have a Skype client running on your home machine logged in as one account. Have Skype on your laptop on another account. Initiate a connection between the two of them and wind up with secure, encrypted access through the firewall from wherever you are. Being peer-to-peer, there would be no central servers or infrastructure required (outside the usual Skype p2p cloud.) This would require, of course, a yet-to-be-created "extra" that connected into the Skype client API and was installed on both systems...but that was the point of the article... more»
With my post earlier this month about the possibility of SIP botnets [also featured here on CircleID], I've had a number of people asking about more information and wondering about the possible impacts. And while I will write more on botnets in general, as far as the potential impact of "botnets" in general, one need only look over at the current situation in Estonia... Now, perhaps Russia is behind the attack... perhaps not. There are obviously much larger political issues going on between the two states. more»
A story... ZZZ Telemarketing (not a real name) is locked in a heated fight with their bitter rival, YYY Telemarketing (also not a real name), to win a very large lead generation contract with Customer X. Customer X has decided to run a test pitting the two companies against each other for a week to see who can generate the most leads. The ZZZ CEO has said to his staff that it is "do or die" for the company. If they fail to win the contract, they will have to shut down -- they need to do "whatever it takes" to win over YYY. A ZZZ staffer discovers that part of why YYY has consistently underbid them is because they are using SIP trunks to reduce their PSTN connection costs. But the staffer also discovers that YYY is using very cheap voice service providers who run over the public Internet with no security... more»
