ndnping results

[ebagies]

hi,

when I do ndnping, the result shows as the following:
PING /ndn/h1-site/h1
nack from /ndn/h1-site/h1: seq=908807860193924757 time=9.50899 ms reason=NoRoute

--- /ndn/h1-site/h1 ping statistics ---
1 packets transmitted, 0 received, 1 nacked, 0% lost, 100% nacked, time 0 ms

My Question:
what does it mean by "nacked" and "NoRoute"

Thanks in advance
Enas Bagies

Means there is no route to /ndn/h1-site/h1 in nfdc fib. Can you check nfdc fib on the node and also share the topology?

thanks for your reply.

here are requested screenshots

Okay so /ndn/h1-site/h1 is present on h2. Is the ndnpingserver running on h1 node?

here is the content of experiment that contains ndnpingserever. Also, I need to mention that ndnpinping works successfully with other nodes that are not directly connected to h1!

Experiment file:

from ndn.experiments.experiment import Experiment

import time

class pingExperiment(Experiment):

def __init__(self, args):

    Experiment.__init__(self, args)

def setup(self):
    self.checkConvergence()
def run(self):
    nodeh1 = self.net['h1']
    nodeh1.cmd("ndnpingserver /ndn/h1-site/h1 &> /dev/null &")
    self.net['h2'].cmd("ndnping -c1 /ndn/h1-site/h1 > ndnping.txt &")		
    self.net['h3'].cmd("ndnping -c1 /ndn/h1-site/h1 > ndnping.txt &")
    self.net['h4'].cmd("ndnping -c1 /ndn/h1-site/h1 > ndnping.txt &")
    self.net['h5'].cmd("ndnping -c1 /ndn/h1-site/h1 > ndnping.txt &")
    self.net['h6'].cmd("ndnping -c1 /ndn/h1-site/h1 > ndnping.txt &")
    self.net['h7'].cmd("ndnping -c1 /ndn/h1-site/h1 > ndnping.txt &")
    self.net['h8'].cmd("ndnping -c1 /ndn/h1-site/h1 > ndnping.txt &")
    self.net['h9'].cmd("ndnping -c1 /ndn/h1-site/h1 > ndnping.txt &")
    self.net['h10'].cmd("ndnping -c1 /ndn/h1-site/h1 > ndnping.txt &")

Experiment.register("ping", pingExperiment)

Not sure, maybe time.sleep for 1 or 2 seconds after running ndnpingserver?

[ebagies]

ok I will try this.

Thank you
