VoIP

Voice-over-Internet protocol (VoIP) is a protocol optimized for the transmission of voice through the Internet or other packet-switched networks. VoIP is often used abstractly to refer to the actual transmission of voice (rather than the protocol implementing it). This latter concept is also referred to as IP telephony, Internet telephony, voice over broadband, broadband telephony, and broadband phone. VoIP can facilitate tasks and provide services that may be more difficult to implement or more expensive using the PSTN. Examples include: The ability to transmit more than one telephone call over the same broadband connection. This can make VoIP a simple way to add an extra telephone line to a home or office. Conference calling, call forwarding, automatic redial, and caller ID; zero- or near-zero-cost features that traditional telecommunication companies (telcos) normally charge extra for. Secure calls using standardized protocols (such as Secure Real-time Transport Protocol.) Most of the difficulties of creating a secure phone connection over traditional phone lines, like digitizing and digital transmission, are already in place with VoIP. It is only necessary to encrypt and authenticate the existing data stream. Location independence. Only an Internet connection is needed to get a connection to a VoIP provider. For instance, call center agents using VoIP phones can work from anywhere with a sufficiently fast and stable Internet connection. Integration with other services available over the Internet, including video conversation, message or data file exchange in parallel with the conversation, audio conferencing, managing address books, and passing information about whether others (e.g. friends or colleagues) are available to interested parties. Advanced Telephony features such as call routing, screen pops, and IVR implementations are easier and cheaper to implement and integrate. The fact that the phone call is on the same data network as a users PC opens a new door to possibilities. Read the full background at VoIP Wikipedia

Hunting Unicorns: Myths and Realities of the Net Neutrality Debate

In many ways, the emotionally charged debate on Network Neutrality (NN) has been a lot like hunting Unicorns. While hunting the mythical horse could be filled with adrenalin, emotion, and likely be quite entertaining, the prize would ultimately prove to be elusive. As a myth, entertaining; but when myths become reality, then all bets are off. The Network Neutrality public and private debate has been filled with more emotion than rational discussion, and in its wake a number of myths have become accepted as reality. Unfortunately, public policy, consumer broadband services, and service provider business survival hang in the balance. more»

FCC's Comcast Ruling Inconsistent and Incoherent

After voting on the Comcast order today, Kevin Martin and his Democratic Party colleagues issued press releases telling us how they saved the Internet from Comcast's discriminatory practices, but they've failed to release the actual order they adopted and subsequently re-wrote. Commissioner McDowell wasn't allowed to see the revised order until 7:00 PM the night before the meeting. Rumor has it that high-level spin doctors are still trying to remove all the rough edges, inconsistencies, and factual errors. more»

Introductory Remarks from Innovation '08

Here's my opening remarks from Media Access Project's Innovation '08 in Santa Clara this morning. A DVD will be available shortly. This was a lively discussion, with Google and Vuze on the case. Good morning and welcome. My name is Richard Bennett and I'm a network engineer. I've built networking products for 30 years and contributed to a dozen networking standards, including Ethernet and Wi-Fi... I'm opposed to net neutrality regulations because they foreclose some engineering options that we're going to need for the Internet to become the one true general-purpose network that links all of us to each other, connects all our devices to all our information, and makes the world a better place. Let me explain. more»

Canadians Aren't Buying Into Net Neutrality

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»

Managing Internet as a Shared Resource: Reasonable Technical Constraints?

The internet is a shared resource. Different access providers begin mixing traffic at different places, but sooner or later, my internet gets mixed into yours. The Canadian Association of Internet Providers (CAIP) application to the Canadian Radio-television and
Telecommunications Commission (CRTC) seems to acknowledge this shared nature with its reference (at paragraph 50 of its application) to the description of the Gateway Access Service its members resell, a description complete with a graphic of a cloud -- a sign that the resource is being shared... more»

Telcos Must Become Major Destination Websites, Says Sun Chairman

Telecommunication companies need to go beyond just providing bandwidth and look into acquiring Internet destination sites that are heavily trafficked, Sun Chairman Scott McNealy said on Friday. "I have explained to every telco that either you become a destination site, or the destination site will become a telco," McNealy said at a news conference at Sun's Worldwide Education and Research Conference in San Francisco on Wednesday... more»

On Comcast and Net Neutrality: Shouting Fire in a Theater

The Comcast traffic shaping case has stirred up passionate debate. Net neutrality proponents are calling for Comcast's head on a platter. The common argument is that Comcast's policy may stifle innovation and competition. If a service provider is allowed to exercise unregulated discretion in how it treats subscriber traffic, it is a slippery slope toward anti-competitive practices. Net neutrality says keep your hands off. Some are preaching net neutrality as if it were an inalienable human right like freedom of speech... more»

IPv6 Over Satellite: Pie in the Sky?

I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world... more»

Call for Telecom Industry Wake-Up

As many of you know, I'm launching the Emerging Communications (eComm) conference -- taking place next month in Silicon Valley, at the Computer History Museum. Communications innovation has been stagnant, in my opinion, for nearly a decade. Telecommunications and Internet communications both seem to be at somewhat of an impasse. The communications industry needs a forum to help break through the stagnancy and highlight the huge opportunity space that is emerging. The stagnancy has been strikingly more so in telecommunications... more»

IPv6: Do as I Say or Do as I Do?

How important is it for a vendor, service provider or integrator to be using a service or technology that it is pushing on its clients? When Voice over IP (VoIP) came out Cisco began a gigantic push, having its salespersons pitch it to anyone and everyone on their client list. But Cisco had not yet deployed VoIP within its own corporate network. It was still making use of traditional voice systems from vendors that today it probably considers competitors. Many people on the receiving end of a sales pitch recognized this... more»

Stealing VoIP Services: Convicted Hacker Interviewed

Up to 300 Megawatt Worth of Keepalive Messages to be Saved by IPv6?

The Time Square Ball bringing in 2008 had more than 9,500 LED bulbs displaying 16 million colours while consuming power equivalent to about ten toasters. This compares to 600 incandescent and halogen bulbs adorning last year's Ball. Easy to forget that most mobile devices used by Time Square revelers were behind IPv4 NAT's and that always on applications such as Instant Messaging, Push e-mail, VoIP or location based services tend to be electricity guzzlers. It so happens that applications that we want always to be reachable have to keep sending periodic keepalive messages to keep the NAT state active... more»

Walks Like a Telco, Yalks Like a Telco… Must be a Telco

Vonage's latest woes are written up by Om Malik in Vonage: How Low Can You Go. More interesting than Om's reportage (Sprint wins case, Vonage ordered to pay damages, stock drops to $1.30) is the commentary afterward, in which one reader takes Om to task for the "gleeful" way in which he reports the demise of the VoIP companies... Boosters made the argument that VoIP was fundamentally cheaper than the TDM systems that phone companies deploy, and so therefore they enjoyed a price advantage in the market place. Anyone in the business of supplying telecom equipment, however, will tell you that the argument is flawed... more»

The Third Stage of the VoIP Rocket Never Fired

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»

Study Says Email Has Surpassed Telephony as Corporate Communication Tool

New research recently released by Dimension Data suggests that email usage has surpassed telephony as communication tool of choice in the workplace. The research surveyed 390 IT managers and 524 enterprise users across 13 countries in the United States, Asia Pacific and Europe, Middle East and Africa. According to the research, 100% of the end-users surveyed use e-mail, followed by fixed-line telephony (80%), mobile telephony (76%) and instant messaging (66%). more»
