Hi Sakib,
You can get all the flows by using OFPFlowStatsRequest and OFPFlowStatsReply
message.
http://ryu.readthedocs.org/en/latest/ofproto_v1_3_ref.html#ryu.ofproto.ofproto_v1_3_parser.OFPFlowStatsRequest
http://ryu.readthedocs.org/en/latest/ofproto_v1_3_ref.html#ryu.ofproto.ofproto_v1_3_parser.OFPFlowStatsReply
e.g.) req = ofp_parser.OFPFlowStatsRequest(datapath, 0,
ofp.OFPTT_ALL,
ofp.OFPP_ANY, ofp.OFPG_ANY)
And, to delete all flows and a single flow, please refer to the OFPFlowMod
message.
http://ryu.readthedocs.org/en/latest/ofproto_v1_3_ref.html#ryu.ofproto.ofproto_v1_3_parser.OFPFlowMod
FYI, to delete all flows, the match value of OFPFlowMod message should be None
(or {}).
Thanks,
Iwase
