Previously Comcast argued that, I believe it was Level 3, was "pushing 5 times more data onto their network than Comcast was pushing onto theirs"

This made me laugh seeing as every one of Comcast's customer ISP packages have 5 times higher download speeds than upload speeds.

It's almost as if Comcast is forcibly causing an imbalance of traffic so they can extort more money out of Tier 1 providers.
