Courtesy of Xfinity and Charter overprovisioning most neighborhood’s circuits, we already have that today for a significant subset of U.S. Internet users due to the resulting Bufferbloat (up to 2500ms on a 1000/30 connection!)
- p1mrx 9mo agoHave you seen excessive bufferbloat on a DOCSIS 3.1 modem?
- altairprime 9mo agoYes.
- vitus 9mo agoYou probably meant to say oversubscribing, not overprovisioning. Oversubscription is expected to a certain degree (this is fundamentally the same concept as "statistical multiplexing"). But even oversubscription in itself is not guaranteed to result in bufferbloat -- appropriate traffic shaping (especially to "encourage" congestion control algorithms to back off sooner) can mitigate a lot of those issues. And, it can be hard to differentiate between bufferbloat at the last mile vs within the ISP's backbone.
- altairprime 9mo agoOk.
