Hi! However, in my personal case, there's also the fact that WBM has been evolving in a direction that I don't feel comfortable with (less technical content, more self- promotion, tolerance for bomb-makers, etc.) Self-promotion of good ideas is not necessary bad. And others are there to

That was our intuition too, but experiments we did in Brussels using 802.11n multiradio routers, with Benjamin and Juliusz, seemed to show that packet loss (as measured by babel at least) is not always correlated to throughput. I do not claim to understand how this is possible. It's not

The metric is simply based on TQ. C=S will probably have a better local TQ than C'-S because of the load balancing over the two links, Sorry for the confusion, I used « = » to mark a different frequency than « - ». There's only the one link between C and S, it's just using a different

With such metric, you don't make any difference between a 56K telephone line and a 10Ge NIC. If you 10Ge has 5pc packet loss and your 56K line has 0pc, your TQ will be prefer the 56k link. If my 10Ge has 5% packet loss, its broken. I don't want to use it. Falling back to the 56K link is the
