[Cerowrt-devel] Network behavior of Moca bridges

[Aaron Wood]

In about 2 months, I'll have my hands on some HomePlugAV devices that I can
do extensive testing with.  My previous tests were showing very, very large
bufferbloat, when used on poor links (2000ms of buffering and growing over
a 1-2 minute rrul test that wasn't able to get over 10Mbps due to SF
Victorian wiring issues).
