Hi,
>From OpenFlow spec v1.3 said this:
"Packets sent to OFPP_TABLE may be forwarded back to the controller as the
result of a
flow entry action or table miss. Detecting and taking action for such
controller-to-switch loops is outside the
scope of this speci cation. In general, OpenFlow messages are not guaranteed to
be processed in order,
therefore if a OFPT_PACKET_OUT message using OFPP_TABLE depends on a flow that
was recently sent to the
switch (with a OFPT_FLOW_MOD message), a OFPT_BARRIER_REQUEST message may be
required prior to the
OFPT_PACKET_OUT message to make sure the flow entry was committed to the flow
table prior to execution of OFPP_TABLE."
Are there other methods to detect controller-switch loop in ryu? or only
barrier msg?
How to send and recive barrier msg?
Thanks for help
Maurizio
