[Dxspider-support] SECURITY MEASURES TO MINIMIZE ATTACKS

[Mikel EA2CW]

Thanks Anthony,

Well, I think they are different POVs. I see the cluster network as a 
peer-to-peer net, not a pyramidal structure. I mean, I don't receive the 
spots from some nodes and pass them to others. The spots can come from 
any node in the net, and they will be distributed to all other nodes, 
not up to the upper levels or down to the lower ones. That is how the dx 
cluster network is structured.

I mean, there is not a "master cluster/group" of nodes and then 
secondary ones, tertiary, etc., but all at the same level, not some 
being the spots "servers" and others the "clients". The spots flow in 
both directions, and so the connections might be (IMHO), as far as I 
understand it.

Just a different point of view...
