The dispute
While acknowledging that Level 3 traffic going to Comcast subscribers is much greater than the traffic coming from Comcast subscribers, the company argues that this imbalance is irrelevant to the issue of whether a broadband access provider like Comcast is entitled to payment of a toll. The nature of local access network traffic implies that this traffic imbalance will exist everywhere across the Internet and so this is not a peering issue between two backbone operators.
Significantly, Level 3 believes that “Comcast also has a strong motive to discourage competition with its cable TV service. Online distribution of movies, TV shows and other content threatens Comcast’s traditional ‘closed’ video distribution model.”http://www.level3.com
