Iterative routing for Pastry networks

[Robert Langenberg]

Hello,

I am currently running Pastry simulations with OverSim and was trying to run a
Pastry network with iterative routing. I changed the Pastry configuration
provided in the default.ini with OverSim to iterative routing and
overrideNewPastry = true. Running the 30 nodes Pastry network from omnetpp.ini
results in many of the nodes not connecting but only a small fraction of the
nodes forming a network on my machine. Is this a known problem or should i
have changed other settings aswell? Setting overrideNewPastry = true works fine
for semi-recursive routing.

The only configuration line changed is in default.ini under pastry settings
# old state
#**.overlay*.pastry.routingType = "semi-recursive"
# new state
**.overlay*.pastry.routingType = "iterative"

#old state
#**.overlay*.pastry.overrideNewPastry = false
#new state
**.overlay*.pastry.overrideNewPastry = true

Thanks a lot

Regards
Robert Langenberg

I'm afraid, iterative routing in pastry is currently broken. Something
goes wrong during the nodes' joining procedures. Anyway, this is a hack.
In the original paper, Pastry does not support iterative routing. Have
you tried to use Bamboo?

I am simulating Pastry with exhaustive-iterative routing, but I did
not set overrideNewPastry = true. All nodes join the overlay. Is there
just a problem with overrideNewPastry = true, or is it generally not
possible to simulate Pastry with (exhaustive-)iterative routing though
it is implemented?

Hallo,

thank you for your suggestions, but since I focus on the new Pastry
implementation I cannot make use of old Pastry or Bamboo at the moment.

Thank you & best regards,
Robert
