Hi
If I want to get the ( continuous ) data packet flow (same as the packet flow
from one switch to another switch) from the controller to specific host/switch,
what I have to do ?
Please note that I want to get a continuous data flow from the controller to a
specific host/switch. you can compare it as the flow rule set in the switches.
Now, OFPPacketout only sends a message to switch once. But I want to get the
continuous data packet sending from the controller to a specific switch.
It will be so much helpful for me, if you kindly discuss this thing with coding
:)
Thanks
-Tanvir

Hi,
You can use Packet-Out messages for such purpose, I guess.

Thanks,
Iwase

HI,
Thanks for your reply!!
def send_packet_out(self, datapath, buffer_id, in_port):
ofp = datapath.ofproto
ofp_parser = datapath.ofproto_parser
actions = [ofp_parser.OFPActionOutput(ofp.OFPP_FLOOD, 0)]
req = ofp_parser.OFPPacketOut(datapath, buffer_id,in_port, actions)
datapath.send_msg(req)
In these codes of the example, i can't find data the controller send.
I think it can't send data what i want to send.
Thanks,
Alan

Hi,
Please refer to the 'data' attribute of OFPPacketOut.
You can set a binary type value, which you want send, into this attribute.
e.g.)
req = ofp_parser.OFPPacketOut(datapath, buffer_id,in_port, actions,
data=<BINARY_TYPE_VALUE>)
FYI: For building a binary type packet data, Ryu provides the packet libraries.
'bin_packet' in the following example is a binary type value to send.

It's something like this echo package
pkt = packet.Packet()
pkt.add_protocol(ethernet.ethernet(ethertype=pkt_ethernet.ethertype,
dst=pkt_ethernet.src,
src=self.hw_addr))
pkt.add_protocol(ipv4.ipv4(dst=pkt_ipv4.src,
src=self.ip_addr,
proto=pkt_ipv4.proto))
pkt.add_protocol(icmp.icmp(type_=icmp.ICMP_ECHO_REPLY,
code=icmp.ICMP_ECHO_REPLY_CODE,
csum=0,
data=pkt_icmp.data))
pkt.serialize()
data = pkt.data
actions = [parser.OFPActionOutput(port=port)] # port of host
out = parser.OFPPacketOut(datapath=datapath,
buffer_id=ofproto.OFP_NO_BUFFER,
in_port=ofproto.OFPP_CONTROLLER,
actions=actions,
data=data)
datapath.send_msg(out)
You need to set your own configuration if you want that this example works,
but this is the idea.
