Iran's Internet Censorship Creates Deep Packet Firestorm
Debate bubbles over surroundig Nokia-Siemen's work in Iran...
The network traffic snooping power of Deep packet inspection
(DPI) has many legitimate uses on an ISP network, but has gained notoriety in recent years for its use in delivering behavioral ads
, and identifying (and ultimately filtering
) P2P traffic. Like most technology DPI isn't inherently bad, but the way it can be used and mis-used by carriers or governments certainly may be.
Evolution in DPI technology has ISPs not only buying and selling your online habits, but hardware vendors push the technology as a new Internet policing solution, placing the onus on ISPs to someday compare every packet a user sends to a master database of what's legal or moral. The negative uses of DPI led to recent hearings exploring how broadband ISPs use the technology, and whether stronger privacy guidelines are needed.
The technology got an additional black eye this week when the Wall Street Journal reported
that Iran was using Western-developed implementations of the technology by Nokia-Siemens to slow and censor traffic related to the ongoing protests in the country. Wired News
claims a boycott of Nokia-Siemens has started, though evidence of the boycott seems scarce. Nokia Siemens, in a blog post
, says the Journal got the story wrong:
The restricted functionality monitoring center provided by Nokia Siemens Networks in Iran cannot provide data monitoring, internet monitoring, deep packet inspection, international call monitoring or speech recognition. Therefore, contrary to speculation in the media, the technology supplied by Nokia Siemens Networks cannot be used for the monitoring or censorship of internet traffic.
Consumer advocacy firm Free Press proclaimed
that the use of DPI in Iran is a warning for Americans about the abuse of DPI. Former AT&T engineer David Isenberg wonders
if the Journal's using issues loved by "US techno-leftists" to push a long-standing Iran interventionist position. Since nobody can get into Iran to dig through their networks to check, the best we seem to be getting is speculation
on what Iran's actually doing.
The entire debate's making deep packet inspection's already troubled reputation even worse. Lost in the mix is the fact that for all of its negative qualities, DPI can
be used to help ISPs better manage information flow and bandwidth demand. However, in the wrong hands it can be an accessory to censorship and murder

said by 33358088:That is an absurd supposition. If they were, then one of two things would have happened. You wouldn't have been able to post such a comment - it would have been blocked. Or two, if you had found a way to bypass the filters, you would have been arrested and imprisoned.
HEY BELL canada and rogers, what ya doing with DPI these days , is it anything like iran?

Nokia says just providing voice tapping capability Basically, Nokia-Siemens says all their hardware can do is tap voice calls. No different than can be accomplished by any Central Office telephone center in the world. Police tap voice calls all over the world, some with warrants and some without.
To clarify: Nokia Siemens Networks has provided Lawful Intercept capability solely for the monitoring of local voice calls in Iran. Nokia Siemens Networks has not provided any deep packet inspection, web censorship or Internet filtering capability to Iran.If Nokia is correct then the threatened boycott is unwarranted.
In most countries around the world, including all EU member states and the U.S., telecommunications networks are legally required to have the capability for Lawful Intercept and this is also the case in Iran.
Nokia Siemens Networks provided TCI, the Iranian national operator, with the capability to conduct voice monitoring of local calls on its fixed and mobile network.

The question I keep asking every website is WHY THE HELL ISN'T SSL IMPLEMENTED YET!
Even dslreports doesn't have https and this place goes on and on about DPI and ISP censorship.
Hmmm... As disheartened as I am by the Iranian government's handling of the situation over there, boycotting the hardware developers over here seems to make as much sense as boycotting automobile manufacturers every time someone gets hit by a car. A tool is a tool is a tool; abuse is in the hands of the user.

The riot police there don't have the guns that people are being killed by. They don't even have guns, only the military does.
I have a feeling foreign powers are making some of the chaos occur over there, while some of it is caused by the people themselves.
Don't be so quick to judge a situation you've never seen except through your own controlled media.
You sit and say the police don't have weapons, and that may be true... at least on paper. The reality is that whoever the government decides to give weapons has weapons, be they police, snitch, military or civilian.
Come let us reason together.

said by Vtr_Racing:Timezone searches are just the first step in a trace.
The more people at this location, the more of a log jam it creates for forces trying to shut down Iranians' access to the internet. Cut & paste; pass it on.
Generally speaking though, I'm curious to see how long before net neutrality and corporate/government censorship clash in a serious firefight.
