Re: Ads? Problem here is the isp owns the stream.
Just like Sandvine , they can forge tcp packets with DPI , it depends on how crafty they get.
I think Karl is making these devices a little nicer then they really are. And I am sure they didn't give him decent details so I don't blame him.
With DPI they can pick off a packet destined for say google. You searched for dog leashes, they will not instead of showing you the ads from google intercept and send you off to another ad. They will tack their ads onto googles.
Nice knowing this , however these devices can forge packets as well. So now they can see you blocked an ad of theirs, and go and inject a redirection on the fly so you think the ads are from google , but are being served up via a redirection from their local ad server.
I have to do this at work a lot to keep people off youtube and other sites like it. It is wrong but it's a place of business. These folks are doing the same on a isp that we pay for , not nice.

Certainly not my intent. The potential for abuse here is vast. But injection over the top of existing advertising relationships is not happening - yet.
I'd bet you're 100% correct that ultimately Ad-blocking applications are targeted and conquered.
I also am consistently annoyed that providers whine about funding upgrades and p2p users when they're consistently finding these new revenue streams without lowering prices. |

Puking out a copy of a captured packet with the RST bit set to 1 and injecting viable content into an existing TCP session and having it properly render are completely different scenarios.
You're talking about the difference between building a paper airplane and building a space shuttle. To do the ad injection you would have to pass all port-80 traffic through content engines which could adjust the composition of the layer7 data to ensure proper rendering by web browsers. |

Comcast, for example, hasn't raised prices in at least the last 6 years, meanwhile inflation has marched on. If you adjust for inflation then the price does indeed go down each year, and speeds have increased from 1.5/3mbps to 6/8mbps over that same period. |
