Now that I think of it, since TCP wants a minimum of two un-acked packets, you can just reduce the rate of your ACKs to keep the sender from flooding. Total hack of course. It's really a packet-pacing issue. On Fri, Jan 27, 2017 at 6:11 PM, Benjamin Cronce wrote: > In the past I've seen issues w

In the past I've seen issues with Windows Updates because the CDN was 1 ms away. TCP wants to have 2 segments in flight, resulting in a non-responsive TCP stream below 13Mb/s. CDNs with low RTTs cause cause issues with low bandwidth connections. Not only does DSL tend to have a low first hop latenc

Hi Eric, quick question from the peanut gallery: on a typical home router with 1Gbps internal and <<100Mbps external interfaces, will giant packets will be generated by the 1Gbps interface (with acceptable latency)? I ask, as what makes sense on a 1000Mbps ingress link, might still block an 20M
