Hi,
I have been experimenting with Mininet for some time and I noticed that
_not_ all packets that do not match a flow entry are being forwarded to
the controller.
I have a UDP stream from a host to another across a linear topology of 5
switches. While changing the rules on the switches, I expect some
packets not to find a matching rule on one or more switces. However the
number of packets the receiver reports lost is always greater than the
total number of packets the switches send to the controller (i.e. The
receiver loses 70-80 packets while only 20-30 packets are sent to the
controller).
According to the OpenFlow specs, aren't switches supposed to forward all
table misses to the controller? Is there something obvious I am missing
here?
Thanks and regards,
