<div>Hi,</div>
<div>I have 10 systems running olsrd (0.6.1). To test scalability, I set up a simple network topology.</div>
<div>To minimize radio interference and maximize the results, I assigned different channels to each wireless link. Because the node is running with AC power, I also set Willingness to 6 not 3. I found some routing brokerage betweeen nodes. For this report, the brokerage happened between node 5 andf node 6.</div>
<div> </div>
<div>Internet --- Node1 ---- Node2 ---- Node3 ----- Node 4 ----- Node 5 -----Node 6 ----Node 7-----Node 8-----Node9----Node10<br clear="all">(ch) 161 161 149 149 153 153 157 157 165 165 1 1 11 11 6 6 9 9 <br>
</div>
<div> </div>
<div>I also assigned the following simple woing schemes to each node.</div>
<div>Node1: wlan0 10.10.10.10</div>
<div> lan 192.168.10.1</div>
<div> wan 172.31.1.88</div>
<div> </div>
<div>Node 2: wlan0 10.10.10.20</div>
<div> wlan1 10.10.10.21</div>
<div> lan 192.168.20.1</div>
<div> </div>
<div>Node 3: wlan0 10.10.10.30</div>
<div> wlan1 10.10.10.31</div>
<div> lan 192.168.30.1</div>
<div>.....</div>
<div> </div>
<div>Node 9: wlan0 10.10.10.90</div>
<div> wlan1 10.10.10.91</div>
<div> lan 192.168.90.1</div>
<div> </div>
<div>Node 10: wlan0 10.10.10.100</div>
<div> lan 192.168.100.1</div>
<div> </div>
<div> </div>
<div>For this case, node1-to-node5 seems to be well but the rest of the nodes are separated as I can show the following observations.</div>
<div>Link between node 5 and node 6 seems to be broken. When I rebooted all of the nodes, then link brokerage is happening at one of the nodes such as 2 or 4. When I planned to test this configuration, I thought all of the nodes have to be linked although the nodes have different hop metric.</div>
<div>In addtion, is there any olsr related performance results that I tried to test my case? </div>
<div>Why doe the routing metric only show 2 or 0? Any helps and commests will be very appreciated... </div>
