Is this ultimately just to free up bandwidth in areas limited by poor last mile infrastructure? The US has some of the cheapest transit network bandwidth costs in the world. Most ISPs can peer to YouTube(Google) for free minus the cost of equipment/data center ports. Thus, is this just addressing the last mile problem again, when the video finally makes it to the neighborhood and you just have too many people on a single DOCSIS node?


A well engineered DOCSIS network can really scream. Unfortunately it’s way cheaper to oversubscribe since 99.99% of the time no one complains.


well-engineered vs oversubscribed is a false dichotomy. A well-engineered network is an oversubscribed one.


well trying to use a cable network is your problem there


Similar bottlenecks occur in FTTx/DSL networks. For example, uplink congestion on a DSLAM or L2 aggregation device.
