Hi,
Umm, I couldn't reproduce your situation.
I use OpenVSwitch, and with it, I could get different duration_sec and
duration_nsec values like this:
OFPPortStats(port_no=4294967294,rx_packets=0,tx_packets=0,rx_bytes=0,tx_bytes=0,rx_dropped=0,
tx_dropped=0,rx_errors=0,tx_errors=0,rx_frame_err=0,rx_over_err=0,rx_crc_err=0,collisions=0,
* duration_sec=739,duration_nsec=140000000*)
What switch do you use?
I guess the problem is in your switch, not in Ryu.
Please ask the development team of your switch.
Thanks,
Fujimoto

Hi,
I was experimenting with ryu, openflow stats request/reply, and
mininet. I noticed that duration_sec and duration_nsec are always the
same for each reply and they have same values i.e duration_sec =
duration_nsec.
Is it the right behavior? shouldn't the values be different?
Because openflow specification says: "The duration_sec and
duration_nsec fields indicate the elapsed time the port has been
configuredinto the OpenFlow pipeline. "
here is a sample of the port_stats_reply:
port stats reply body content [
OFPPortStats(port_no=1,rx_packets=22,tx_packets=0,rx_bytes=1056,tx_bytes=0,rx_dropped=0,tx_dropped=0,rx_errors=0,
tx_errors=0,rx_frame_err=0,rx_over_err=0,rx_crc_err=0,collisions=0,*duration_sec=4294967295,duration_nsec=4294967295*),
OFPPortStats(port_no=2,rx_packets=22,tx_packets=0,rx_bytes=1056,tx_bytes=0,rx_dropped=0,tx_dropped=0,rx_errors=0,
tx_errors=0,rx_frame_err=0,rx_over_err=0,rx_crc_err=0,collisions=0,*duration_sec=4294967295,duration_nsec=4294967295*),
]
Thank you.
