Sorry. None of this make sense to me. This is my understanding of how the modules work in NOX: * The spanning tree module calculates the spanning tree and set the flood bits for the port config accordingly. That's all it does. No path calculation, etc. * And the routing module is really just

If you wanted to compare against something that already exists, the only thing I can think if would be the routing module along with the spanning tree module. -- Murphy On Sunday, May 22, 2011 06:44:15 AM marwen mechtri wrote: > Hi all, > > could you tell me please if there is a module that ca

Hi all, could you tell me please if there is a module that calculates the shortest path (it handles loops). Best regards Marwen 2011/5/20 marwen mechtri > Hi all > > Thank you for your replay. > > I said "the module don't give any result" because when I ping form source > host the destination

Hi all Thank you for your replay. I said "the module don't give any result" because when I ping form source host the destination is not reachable. I think it's a problem of loop, because in a partial mesh I have many path from source to destination. I developed a Nox application and one of the f

What do you mean by "don't give any result"? Do you have NOX working on topologies besides your partial mesh one? You'll need to have the topology component and probably the discovery component running, so please make sure they are (start nox with -v or -v -v). Your problem may be that the rout

Hi Marwen. Nox routing implements OSPF protocol and It is based on Dijkstra algorithm (also called SPF). In this algorithm, the component knows the data of all nodes in the network. Hope it helped. Best Regards. 2011/5/19 marwen mechtri > Hi all, > > I'm exploring "routing", "sample_routing"
