Re: [Peerfactsim-developer] Problems with Net-Layer

Hi Robert,

> When we use :
"de.tud.kom.p2psim.impl.network.simple.SimpleNetFactory" "de.tud.kom.p2psim.impl.network.simple.SimpleStaticLatencyModel"
as net-Layer configuration the Analyzer gives use the amount of Neighbors, we expect for every Peer.
There is no Problem if there are not more then 100-200 Peers we simulate.
But if we want to simulate more peers, the simulator gets very slow. The simulation then takes a lot of time.

Which analyzer are you using for the simulations? As far as I know, there is no analyzer which records the amount of neighbours of each peer. Are you talking about overlay neighbours? If so, why do you analyze it in the network layer?

It would be fine to get more information about the evaluative scenario you are running. Which components (specified in the xml file) are selected for the simulations?

Cheers,

Betreff: [Peerfactsim-developer] Problems with Net-Layer

Hi there,

i´m writing, 'cause we have a Problem running our configuration within the simulator.

When we use :
"de.tud.kom.p2psim.impl.network.simple.SimpleNetFactory" "de.tud.kom.p2psim.impl.network.simple.SimpleStaticLatencyModel"
as net-Layer configuration the Analyzer gives use the amount of Neighbors, we expect for every Peer.
There is no Problem if there are not more then 100-200 Peers we simulate.
But if we want to simulate more peers, the simulator gets very slow. The simulation then takes a lot of time.

When we use :
"de.tud.kom.p2psim.impl.network.gnp.GnpBitmapNetLayerFactory"
"de.tud.kom.p2psim.impl.network.gnp.GnpLatencyModel"
as net-Layer configuration the simulation is a lot faster, but the Analyzer tells us, the peers only have 0-3 Neighbors which is way too little and probably false.

Has anyone an idea, why we get this wrong outputs?
Has anyone an other Net-Layer configuration, we can use, which runs quite fast and gives us the right outputs?

Thanks in advance.

Robert
