[Dxspider-support] Bad IP

[Kin]

Hi,

An interesting experiment, using paper and pencil, is to calculate the
average value of a packet sent by a single node to the network, let's say a
spot, with the topology we have.
I think it is very interesting and didactic.

A short time ago I shared here a small study attempt that can help in this
topic:

Measurements in the DXCluster Node Network.pdf  

Regards,

Kin EA3CV

Hi Gregor.

If all 400 nodes peered with eachother, everything would probably stop
working.

Everytime a DX spots is recived from some link partner, it would be passed
on to 399 other nodes, while we would probably get the same spot from I
don't know how many other link partners. In my opinion it would be total
caos. But maybe I misunderstand something.

It woul create a LOT of totally unneeded trafic.

It has never been the intention, that everyone should peer with everyone.
thats why you will probably see, that most nodes have in the range from 3-20
link partners.

Myself have been doing finr with three for many years, but have 5 links now.
and if I miss a single dx spot for whatever reason, it will not kill me.

Maybe Dirk can chip in, and give us some idea what would happen if all nodes
peered with all nodes :-)
