Hey nayan seth
thanks a lot for great description , But This error is appeared , when I run it

Traceback (most recent call last): File "./loadbalancer.py", line 328, in getResponse(deviceInfo,"deviceInfo") File "./loadbalancer.py", line 19, in getResponse deviceInformation(jData) File "./loadbalancer.py", line 35, in deviceInformation if(i['ipv4']): TypeError: string indices must be integers

Could you upload the load balancing code using the REST API for the ONOS controller?
Thank you!

Please Explain how to remove the default balancer, and how to run the .sh script

Just for the idea to see if i have not made any mistake

Hi nayanseth：
I try to change H1 H4 H3 to H1 H5 H6 or H1 H7 H8, I found that the program isn't working. Why can appear such a problem？

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?

Hi,

There you said

1.Remove the official Floodlight Load Balancer.

I used the floodlight v1.2 and found the package named net.floodlightcontroller.loadbalancer, however, if i deleted this package, the floodlight wouldn't work and report the error.

Thank you.

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 .

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
