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
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»
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»
A spammer who goes by the name "Ed" (and sometimes SpammerX ), has gotten out of the business and written a book, "Inside the Spam Cartel: Trade Secrets from the Dark Side". The book, which has had a particular level of interest in the law enforcement circles eager to learn more about the spam business, predicts the spam problem will only get worse. Ed says: "As broadband speeds increase, spammers will increasingly look to market goods by making VoIP calls or sending out videos..." more»
I recently came across a copy of a ruling in the bizarre case of MySpace vs. theglobe.com. Theglobe.com was the ultimate dot.com bubble company. It started up here in Ithaca, and went public at the peak of dot.com hysteria with one of the the greatest one-day price runups ever. Since then they bought and sold a variety of busineses, none of which ever made any money, including the Voiceglo VoIP service which appears to be what the spam was promoting. more»
I have long been intrigued by the question of how do we turn the internet into a lifeline grade infrastructure... My hope that this will occur soon or even within decades is diminishing. Most of us observe, almost daily, how even well established infrastructures tend to crumble when stressed, even slightly... I was at the O'Reilly Etel conference last week. The content was impressive and the people there were frequently the primary actors in the creation and deployment of VOIP. However, not once during the three days did I hear a serious discussion by a speaker or in the hallways about how this evolving system would be managed, monitored, diagnosed, or repaired. more»
What economic and social factors are shaping our future needs and expectations for communications systems? This question was the theme of a joint National Science Foundation (NSF) and Organisation for Economic Co Operation and Development (OECD) workshop, held on the 31st January of this year. The approach taken for this workshop was to assemble a group of technologists, economists, industry, regulatory and political actors and ask each of them to consider a small set of specific questions related to a future Internet. Thankfully, this exercise was not just another search for the next "Killer App", nor a design exercise for IP version 7. It was a valuable opportunity to pause and reflect on some of the sins of omission in today's Internet and ask why, and reflect on some of the unintended consequences of the Internet and ask if they were truly unavoidable consequences... more»
In January of this year, a frontpage article on WSJ quoted Verizon Chief Executive Ivan Seidenberg "We have to make sure they (Google) don't sit on our network and chew up our capacity". Both AT&T and Bellsouth also made similar statements in the same article. A few days ago, Verizon repeat their call to "End Google's Free Lunch": "A Verizon Communications Inc. executive yesterday accused Google Inc. of freeloading for gaining access to people's homes using a network of lines and cables the phone company spent billions of dollars to build." ...it is no surprise that Network Neutrality, a concept where broadband providers are not to discriminate rivals when they charge tolls or prioritize traffic, is now on the agenda of the US Congress. more»
ENUM has a critical role to play in telephony services convergence. Although many carriers are adopting ENUM there are myths swirling around the confuse newcomers. In data networks, the domain name system (DNS) is responsible for converting Uniform Resource Locators (URL's) to IP addresses in order to route data traffic. The ENUM protocol performs a similar essential function of linking E.164 telephone numbers to Universal Resource Identifiers (URIs) -- enabling communication services to use traditional phone numbers to set up calls over IP networks. Unfortunately, there's a good deal of hype and confusion around ENUM, which might lead carriers to delay ENUM implementations. That delay would be a mistake... more»
For some years now the general uptake of IPv6 has appeared to be "just around the corner". Yet the Internet industry has so far failed to pick up and run with this message, and it continues to be strongly reluctant to make any substantial widespread commitment to deploy IPv6. Some carriers are now making some initial moves in terms of migrating their internet infrastructure over to a dual protocol network, but for many others it's a case of still watching and waiting for what they think is the optimum time to make a move. So when should we be deploying IPv6 services? At what point will the business case for IPv6 have a positive bottom line? It's a tough question to answer, and while advice of "sometime, probably sooner than later" is certainly not wrong, it's also entirely unhelpful as well! more»
I'm kinda foxed by the some of the discussion going on about "Net Neutrality". The internet was designed from the outset not to be content neutral. Even before there was an IP protocol there were precedence flags in the NCP packet headers. And the IP (the Internet Protocol) has always had 8 bits that are there for the sole purpose of marking the precedence and type-of-service of each packet. It has been well known since the 1970's that certain classes of traffic -- particularly voice (and yes, there was voice on the internet even during the 1970's) -- need special handling... more»
All those Internet Governance pundits who track ICANN the way paparazzi track Paris Hilton are barking up the wrong tree. They've mistaken the Department of Street Signs for the whole of the state. The real action involves words like rbldnsd, content filtering, and webs of trust. Welcome to the Internet! What's on the menu today? Spam, with some phish on the side! We've got email spam, Usenet spam, IRC spam, IM spam, Jabber spam, Web spam, blogs spam, and spam splogs. And next week we'll have some brand new VoIP spam for you. Now that we're a few years into the Cambrian explosion of messaging protocols, I'd like to present a few observations around a theme and offer some suggestions. more»
In looking at the general topic of trust and the Internet, one of the more critical parts of the Internet's infrastructure that appears to be a central anchor point of trust is that of the Domain Name Service, or DNS. The mapping of "named" service points to the protocol-level address is a function that every Internet user relies upon, one way or another. The ability to corrupt the operation of the DNS is one of the more effective ways of corrupting the integrity of Internet-based applications and services. If an attacker can in some fashion alter the DNS response then a large set of attack vectors are exposed. ...The more useful question is whether it is possible to strengthen the DNS. The DNS is a query -- response application, and the critical question in terms of strengthening its function is whether it is possible to authenticate the answers provided by the DNS. DNSSEC provides an answer to this question. more»
In follow-up to recent announcement on the release of the latest edition of the very popular DNS and BIND book -- often referred to as the bible of DNS -- CircleID has caught up with Cricket Liu, co-author and a world renowned authority on the Domain Name System. In this interview, Cricket Liu talks about emerging issues around DNS such as security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework). "Cricket Liu: We're now seeing more frequent attacks against DNS infrastructure. ...Turns out that name servers are terrific amplifiers -- you can get an amplification factor of nearly 100x. These attacks have raised awareness of the vulnerability of Internet name servers, which is possibly the only positive result..." 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»
I'm sure this is something that's been raked over before, but I don't see a common understanding of what 'Net Neutrality' actually is. Despite many of the Internetorati demanding it by law. There appear to be several different camps, which you could paint as "bottom of IP", "middle" and "top". The bottomistas would see enforced Internet Protocol itself as a premature optimisation and violation of the end-to-end principle. Unhappy that you only get IPv4 or IPv6? Still grumpy that you only have IPv4 and not even IPv6? Really miserable that your VoIP packets are staggering under the poisonous load of IPv6 headers? You're a bottomista. more»
