The net neutrality debate has flared up once again, with arguments between cable operator Comcast and broadband backbone provider Level 3 over new fees for data transport. Level 3 has accused Comcast
of charging extra for content delivered to Comcast subscribers from Level 3's customers, "effectively putting up a toll booth at the borders of its broadband Internet access network, enabling it to unilaterally decide how much to charge for content which competes with its own cable TV and Xfinity delivered content." However, Comcast argues
that this isn't an open access issue, and is in fact Level 3 offering CDN (Content Delivery Network) services to its clients but refusing the pay the going rate for such data transport to Comcast.
