i have a scenario where i draw a network and set all it's paraments on swing based gui, after that i have to translate this network into a python based script which another framework reads and realize this network in the form of virtual machines.
As an example have look here:
from mininet.topo import Topo, Node
class MyTopo( Topo ):
def *__init__*( self, enable_all = True ):
super( MyTopo, self ).__init__()
Host = 1
Switch = 2
self.add_node( Switch, Node( is_switch=True ) )
self.add_node( Host, Node( is_switch=False ) )
self.add_edge( Host, Switch )
self.enable_all()
topos = { 'mytopo': ( lambda: MyTopo() ) }
It simply connects a host to a switch and realize this topology on mininet framework.
Now for now in order to realize the drawn network on java GUI here is what i am doing:
I simply take the information from GUI and creates a new python file like the one above using java code and then run this file in mininet, which works fine somehow.
I want to know, is this the correct and robust way how i am doing this or should i be looking further into java-python bridge like scenarios to be more effective or so as to say more professional.

Hi all,
What's the UNC path to a folder on my local computer, and how can I access it?
I have tried:
1. Security for the folder -- set to Everyone Full Control (for now!)
2. Sharing permissions -- set to Everyone Full Control (for now!)
I can see the folder in \, but can't go in ( is not accessible.)
Error message:
"You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access pernmissions. The network location cannot be reached. For information about network troubleshooting, see Windows Help."
My computer is not connected to a network.
We have an application server which have been observed sending headers with TCP window size 0 at times when the network had congestion (at a client's site).
We would like to know if it is Indy or the underlying Windows layer that is responsible for adjusting the TCP window size down from the nominal 64K in adaptation to the available throughput.
And we would be able to act upon it becoming 0 (nothing gets send, users wait = no good).
So, any info, link, pointer to Indy code are welcome...
Disclaimer: I'm not a network specialist. Please keep the answer understandable for the average me ;-)
Note: it's Indy9/D2007 on Windows Server 2003 SP2.
More gory details:
The TCP zero window cases happen on the middle tier talking to the DB server.
It happens at the same moments when end users complain of slowdowns in the client application (that's what triggered the network investigation).
2 major Network issues causing bottlenecks have been identified.
The TCP zero window happened when there was network congestion, but may or may not be caused by it.
We want to know when that happen and have a way to do something (logging at least) in our code.
So where to hook (in Indy?) to know when that condition occurs?
