Queue configuration is external to OpenFlow, so it seems to me that you can't
expect the controller to magically know which queues to use for what on which
switches.
The first thing that seems reasonable to me is to set the DPIDs for the
switches to known values when configuring them -- at the
Thanks for your reply. Is there anyway that dpid is taken automatically not
to be entered manually??

The event object also has a .dpid attribute which you can use to distinguish
between switches -- each switch has a different DPID.
So you'll want to do something along the lines of...
if event.dpid == :
if packet.find('tcp'):
action = of.ofp_action_enqueue(port = port, queue_id = 3)
...
First of all I created two queues i.e. queue-0 and queue-1 on PORT Eth-1 of
OVS. I use the code below on cotroller
if packet.find('tcp'):
queue=1
elif packet.find('arp'):
queue=0
else:
queue=1
msg = of.ofp_flow_mod()
msg.match = of.ofp_match.from_packet(p
Thanks a lot. In fact I want the same thing which you mentioned and I was
after this since last one month. I am using OVS switch. I will try this.
This is of great help for me.

Yes, you can do this if what you want can be accomplished using the queue types
available in your switch. If that condition is true, then there are several
ways to do it with different tradeoffs. I'd suggest that you start off by
modifying the l2_learning component to assign each new flow to t
I think you mean that I want to achieve from this. I want to get IP
protocol number from packet and then on the basis of that protocol number I
want to assign bandwidth to flows/hosts on the basis of their needs. Like
the protocol number which needs high bandwidth should be allocated high
bandwidth

Dear Marphy McCauley
The link which you provide was very helpful and I found match class in that
and I use this code
import pox.openflow.libopenflow_01 as of # POX convention
import pox.lib.packet as pkt # POX convention
my_match = of.ofp_match(dl_type = pkt.ethernet.IP_TYPE, nw_proto =
pkt.ipv4.
Thanks for your reply. For now, I am just using simple hub code. I just
want to get Protocol number from Protocol field. I tried match class to get
it but I think I use wrong approach. If there is any other method please
let me know that how to get protocol number from flow entry or if it can be

Hello everybody
I am using Mininet 2.0 and POX controller. I am writing a script and I need
to get data from Protocol field i.e. which protocol number is being used so
that on the basis of that protocol number I can take some decision.
I tried of.ofp_match() class but didn't get what I want. It ma
13 matches
