Potential rebalancing of upload and download bandwidth
From what I have heard, a neighborhood node has 4x load-balanced 6.4Mhz 64-QAM upstream channels. Effective throughput per channel is only 26.92Mb/sec. That means the cable modems on a node are all sharing just 107.68Mb/sec. When these channels become saturated, we get packet loss and ping jitter, essentially an unstable connection.
Given that node splits are probably a necessity across the entire US right now (but Cox probably doesn't want to do anything about it since they think this will all blow over in a month or two), is there some way the amount of carved out upstream bandwidth could be improved at a neighborhood node scale? I don't need 500 Mb/s down, I need a consistent connection (which requires both back and forth, upload and download rate, not to be congested).
