<html><head></head><body>This is an active area of research, particularly with the advent of multi-path TCP.<br>
Presently, however, you have to hide the two-link-ness from the TCP layer, and essentially from the IP layer as well.<br>
ECMP would work, as long as both lines are the same (this does not hold true as a dynamic assertion with DSL technology, *ever*).<br>
LACP will *not* work.<br>
If you have Linux boxes at both ends, you can use mod_bonding in its round-robin mode... I've done that in the past and it does work.<br>
<br>
Far more effective, however, would be to upgrade to a symmetric VDSL2 setup that supports DSL bonded pairs.<br>
That'll set you back around $600+ per end, IIRC, replaces both the DSLAM and the DSLR, but makes your problems go away by turning all the copper into a single Ethernet link.<br>
<br>
I just worked with someone else on this kind of setup, I'll see if I can find the links...<br>
