Of course, this only works for traffic to the places where you've deployed bundler, and there is the problem of other people's traffic also going to that destination ("cross-traffic" he called it). I found it interesting. It doesn't solve the problem that I've long been obsessed about, which is finding a way to estimate the total bandwidth cross that "l2" hop between a home CPE and the ISP "CMTS" or "BNG"... such that we can auto-tune thing= s. IETF watchers might also care about the APN (really poorly named in the en= d) BOF, where one use case they care about is where the "L2" hop is actually = a large metro-ethernet. -- ] Never tell me the odds! | ipv6 mesh networ= ks [ ] Michael Richardson, Sandelman Software Works | IoT architect= [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails = [
