hi murphy
i have a path between two hosts(h1 and h2) in a data center,when i ping h2
from h1 since switches on this path have no flow entry for route icmp
packet to h2 , the edge switch that h1 connected to it(e_s1) ,send icmp
packet to controller. in controller i handle it and i add flow entry to
each switch on this path in my controller code and at last send packet out
msg to e_s1 to forward this packet. during this action (ping h2 from h1) i
capture traffic of my network by wireshark and i see packet in msg from
e_s1 two times sends to controller that i expect packet in msg must send
once.
