Following my comments about the iPhone VoLTE announcement I had an interesting conversation with Andy Huckridge from Gigamon, a company that provides intelligent traffic visibility networking solutions for enterprises, datacentres and service providers around the globe. An interesting concept that we discussed was the 'triple challenge of network transformation'. The three elements of this challenge are... more
At the Emerging Communications Conference eComm 2008, I'm moderating a panel "Wireless Innovation, with or without operators." This will be a discussion -- smart people from differing camps responding to (hopefully) probing questions from yours truly, and the audience. Points of view represented include Google Android, J2ME/JavaFX Mobile, iPhoneWebDev.com, Skype and Trolltech Qtopia (Nokia), plus Chris Sacca, formerly head of Google's wireless initiatives. I've been thinking about subjects and questions for the panel. As a start, I'll set down my current views, then seek others' views and questions. more
A buzzword in the cable/ilec world is IPTV, a plan to deliver TV over IP. Microsoft and several other companies have built IPTV offerings, to give phone and cable companies what they like to call a "triple play" (voice, video and data) and be the one-stop communications company. ...I'm at the pulver.com Von conference where people are pushing this, notably the BellSouth exec who just spoke. But they've got it wrong. We don't need IPTV. We want TVoIP or perhaps more accurately Vid-o-IP. 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
Interested in working on an open standard for "secure Caller ID" for voice-over-IP (VoIP)? If so, the new "Secure Telephone Identity Revisited (STIR)" working group was just officially chartered within the IETF and the mailing list is open for all to subscribe. more
The 87th meeting of the Internet Engineering Task Force (IETF) in Berlin, Germany, concluded on August 2, 2013. IETF Chair Jari Arkko recently published his summary of IETF 87 on the IETF Blog highlighting what he felt were some of the more important aspects of what was a very successful IETF meeting. I also had the privilege of interviewing Jari on video about the meeting. 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
The Tyee, an independent on-line magazine based in BC wrote a story about net neutrality more than a year ago, noting that most Canadians are sleeping through the debate. They followed up again last week. Despite what is called a "perfect storm of events that may crystallize the issue for consumers, businesses, politicians, and regulators," there hasn't been an overwhelming outcry, despite extensive press coverage of the most recent network activities. There are a number of voices who present a conspiracy theory on traffic shaping in Canada... more
My weekly Law Bytes column (Toronto Star version, freely available version) examines the growing trend toward a two-tiered Internet, which upends the longstanding principle of network neutrality under which ISPs treat all data equally. I argue that the network neutrality principle has served ISPs, Internet companies, and Internet users well. It has enabled ISPs to plausibly argue that they function much like common carriers and that they should therefore be exempt from liability for the content that passes through their systems. ...Notwithstanding its benefits, in recent months ISPs have begun to chip away at the principle. more
Comcast has been in the news recently for deliberately "slowing down" some subscribers and applications in its broadband cable service. There was an article in the Washington Post today updating the case, and there was a recent article in Network World that actually favors the groups filing the complaints and calls for the FCC to crack down on Comcast. more
Voice over IP (VoIP) represents a sharp break from the traditional telephony. The story of VoIP is important in helping us think beyond the simplistic framing of a "digital transition". The first stage of any technology is emulating the old. Indeed, digital telephony was just like traditional analog telephony -- just FBC (Faster, Better Cheaper) but not fundamentally different. Merely changing from analog to digital isn't transformational in itself. But it creates the opportunity for transformation. more
Ahh, so the telecom incumbents have come up with a "new" idea for the Internet -- usage-based pricing. That's right, more usage (for things like VOIP and video especially) means more costs to operate the network, so users should pay by the bit, or some similar metric. It's all so logical! But wait a minute. I thought what sparked the consumer Internet revolution was the fact that ISPs didn't charge by the minute, but offered flat-rate monthly fees. And what catalyzed the boom in cellular usage here in the US was the shift from heavily usage-based pricing to the largely flat rates we see today... more
Ten years ago was the dawn of Voice over IP (VoIP). The pioneering Israeli company VocalTec had just released its VoIP software for PCs (it was named iPhone, BTW). Industry guru Jeff Pulver (whom I now partner with in FWD) had begun to hold his Voice on the Net (VON) shows. As the founder of VoIP startup ITXC, I was invited to give a keynote at VON in Boston. The evolution of VoIP, I opined with the requisite PowerPoint slides, will be like a three stage rocket. I was right about the first two stages and dead wrong about the third... more
"What is a minimum set of specifications that a vendor must implement to be able to say that it is SIP-compliant?" A friend asked me that question and my response was: "It depends." and even more unfortunately:
"I don't know." It turns out to be a challenging question to answer... and it led me to ask: "How do we define what "SIP" is for telecommunications in 2014? How do we help vendors move their products/services to be based on SIP? As we talk about "turning off the PSTN" and "moving all telecom to IP", how can we make it easier for companies to switch to using SIP? 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
