Having problem in running loadbalancer.py script which is step no. 13
already try command ./loadbalancer.py
but couldn't run that file
IS there anything to configure before running this file?
Could you upload the load balancing code using the REST API for the ONOS controller?
Thank you!
Hi,
I followed the steps mentioned for the project. I am using the floodlight controller, and everything works fine until the step where we run the loadbalancer.py file. The file runs properly, and I also get the best path in the output.
However the last 2 steps are not working. I mean in Step 18, we should only see 10.0.0.3 packets, but I see both the packets i.e 10.0.0.3 and 10.0.0.4.
And in the last step, I don't see any packets. I have also properly selected the ports in both the steps.
Could you please help me?
Thanks

I can't understand the loadbalancer's code why node < 17.
17 means what..... I don't know where 17 comes from.
The following is the code
def findSwitchRoute():
for currentPath in nx.all_shortest_paths(G, source=src, target=dst, weight=None):
for node in currentPath:
tmp = ""
if node < 17:
pathKey = pathKey + "0" + str(hex(node)).split("x",1)[1] + "::"
tmp = "00:00:00:00:00:00:00:0" + str(hex(node)).split("x",1)[1]
expect your reply .thank you .
