<div>olsr will do so as u wanted, but,.. </div><div>.</div><div>but it needs to loose several hello messages till link costs raise enough to take the other (initially quite longer) route</div><div>so the hello interval must be about 1/10 of the reaction time you want to reach (=RT)</div>
<div>.</div><div>furthermore the changes need to be reported to all nodes, so the tc interval must be about 1/5 of RT</div><div>.</div><div>next all nodes must process (and forward) the messages very fast, so the polling interval should be around 1/10 of RT</div>
<div>.</div><div>and finally all nodes must recalculate their routing very fast, so the dijktra limit (minimal interval) must be at least 1/2 of rt</div><div>.</div><div>one hint if your setup is only a-b-c-a, and u want to stream between a and c, and u drop the link c-a, it will react faster, as the alteernative path is shorter/cheaper than your intended setup,...</div>
<div></div><div>regards Markus</div><div></div><div>p.s. abovenumbers are only good guesses from my side, so please report your experience with them, or maybe henning will write a mail as he knows more about fast reacting olsr setups than me</div>
