Dan,
We cannot yet take good advantage of multiple wireless cards and/or
multiple channels, in order to improve performance. I can guide someone
as they implement the requisite improvements to the HSLS daemon. I have
a pretty good idea how to add something like that to the existing daemon.
BTW, I designed the HSLS "Backplane LSA" in anticipation of
multi-radio/-channel nodes. My idea was that by assigning a cost to
cross from interface to interface in the same router, you can express
things like the channel-switching delay, or the (non)interference of
consecutive packets in an IP stream, in a way that lets us use Dijkstra's
algorithm to solve for the best multi-channel/-radio paths. I made
the design without good ideas how to assign the interface-to-interface
costs, though. I still don't know how to do it, but there are more and
more research papers on the multi-* topic.
Has anyone mentioned WCETT by Microsoft, yet?
