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
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
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
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
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
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, 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
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
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
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
