WSJ on Wireless Network Neutrality

Today's Wall Street Journal had an interesting article (subscription required) on the current state of the wireless walled garden. It cites several recent clashes between handset vendors and cellcos over the extent to which consumers can use their phones to access non cellco content. From the article: "At stake for consumers are what services will be available on their mobile phones and whether they're free or cost a monthly fee. The wireless Web is taking off more slowly in America than overseas, and one reason is that U.S. carriers tightly control what applications are available on mobile devices..." more

VoIP: Beyond Digital POTS

I've been involved with VoIP technology since 1996. I've been a public advocate for wideband audio at least since 1997. And I've admired and supported a variety of companies using VoIP to provide innovative services and new user interfaces. But reflecting on the past decade, the only globally significant impact of VoIP has been on prices (by fostering arbitrage). Most VoIP telephony services are just digital POTS... more

Treating Different Types of Communications Differently

A friend who read my Creating Sustainable Network Neutrality paper wrote to say, "Help me understand what is so bad about treating different types of communications differently." That's a really good question! If you want to offer vertically integrated services on special purpose networks, such as video entertainment or pager service or telephony, I do not have a problem with that, provided you don't use your market power to impede Internet applications that offer competing services... more

Skype as a Platform for Secure VPN Tunnels?

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

Frustrations with VoIP Phone Services

I ought to explain why I've suddenly gone cold on VoIP. It's just I've watched my own behaviour. I've grown tired of the inconsistency of PC VoIP calls, and instead I've reverted to using landlines, mobiles and Jajah (for callback). But I'm still using IM to set up many of those calls! The problem isn't unique to any one client - they're all proving unsuitable for business use with clients (which is most of my telephony needs covered). The worst of all seems to be Skype conference calling... more

VoIP/IP Telephony in Estonia: Disrupted by Botnets?

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

Net Neutrality Reflection

So this afternoon my charge is to lay out all the Net Neutrality (NN) issues to a bar association that doesn't have a telecom subcommittee... Cringely says that "In the end the ISPs [network providers] are going to win this [network neutrality] battle, you know. The only thing that will keep them from doing that is competition, something it is difficult to see coming along anytime soon..." more

Clues about the Future of TV

A recent article chronicles the telcos' slow start in cable TV. I don't think the telcos stand a chance of succeeding in cable TV. Instead, if they're to succeed at all, they'll probably buy or form alliances with existing cablecos... But they'd better start swimming, because the times are a changing.. more

More on Broadband Router Insecurity and Being Proactive

Fergie replied on NANOG to my recent post on the subject of broadband routers insecurity: "I'll even go a step further, and say that if ISPs keep punting on the whole botnet issue, and continue to think of themselves as 'common carriers' in some sense -- and continue to disengage on the issue -- then you may eventually forced to address those issues at some point in the not-so-distant future..." He is right, but I have a comment I felt it was important - to me - to make. Not just on this particular vulnerability, but on the "war"... more

Broadband Routers and Botnets: Being Proactive

In this post I'd like to discuss the threat widely circulated insecure broadband routers pose today. We have touched on it before. Today, yet another public report of a vulnerable DSL modem type was posted to bugtraq, this time about a potential WIRELESS flaw with broadband routers being insecure at Deutsche Telekom. I haven't verified this one myself but it refers to "Deutsche Telekom Speedport w700v broadband router"... more

Ready or Not… Here Come the IRC-Controlled SIP/VoIP Attack Bots and Botnets!

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

Ed Richards of Ofcom on Net Neutrality

Ed Richards, Chief Executive of Ofcom, was at Columbia today... NN (Net Neutrality) debate does give us insight into importance of disclosure to consumers -- consumers should be able to switch providers, and they should know which ISPs are making prioritization decisions. This should be an obligation of suppliers to communicate this information to consumers. In particular, he says that Ofcom is actively exploring whether network operators whose traffic shaping activities change materially should have to tell consumers -- and if these changes are significant consumers should be allowed to break their contracts with the provider without penalty... more

Whose Network is it Anyway?

In reading a Q&A with Verizon's Brian Whitten I found this striking Q and A: "Q. With a fiber connection being symmetric, many fiber providers such as Paxio are providing symmetric connections such as 5Mbit, 10Mbit, 30Mbit. Why is Verizon keeping this arbitrary asymmetric limit with Fiber? A. ...Indeed, our FTTP network can easily support a symmetric data service. As market dynamics change, we would re-assess the benefit to our customers of introducing a class of symmetric data services." My reaction is "No thank you, I'd rather do it myself". To understand my reaction you need to recognize the difference between wanting to build my own bridge across a stream and asking why I'm not allowed to cross it myself using my own boat. more

Infrastructure ENUM

After much initial fanfare a couple of years ago ENUM has matured to a state where it is currently yet another under-achiever in the technology deployment stakes. ENUM initially presented itself as a very provocative response to the legacy telco position of monopolising public voice services through their exclusive control over the Public Switched Telephone Network (PSTN) and the associated controlling position over the telephone number space... The perception was that ENUM was going to dismantle these levers of control and open up the voice market to a new wave of competitive carriers. If the address plan was the key to the PSTN, then ENUM was intended unlock this network and position the new wave of Voice Over IP (VOIP) carriers to take over any residual treasures of the traditional voice market. Events have not played out according to these expectations... more

.Mobi Premium Name Auction Off to Wild Success at TRAFFIC in Miami

I'm in attendance at the the TRAFFIC EAST 2006 show, in Hollywood [Miami], Florida. There has been a lot of buzz here about the .Mobi top level domain, ranging from the talk of early registrants hoping to create the next big mobile portal to those that were keen to see implementations of mobile content. There was a domain name auction this evening where flowers.mobi sold for $200,000.00 (USD), and fun.mobi for $100,000.00 (USD) from a long list of domain names in the com, net, info, org, us and mobi extensions. more
