Oh I see - the bindings_storage module would hold that information from nox.netapps.bindings_storage.pybindings_storage import pybindings_storage
self.bindings = self.resolve(pybindings_storage) and then you can use the module's API as defined in netapps/bindings_storage for example self.bindings.get_all_links() would give you a list with tuples of the form (src_dpid, src_port, dst_dpid, dst_port) you can take a look at the code of Glen Gibb's spanning tree module<http://www.openflow.org/wk/index.php/Basic_Spanning_Tree>, which is the only example that comes to my mind that uses the python binding storage API On Tue, Mar 29, 2011 at 3:36 AM, karim torkmen <karim.torkm...@gmail.com>wrote: > On 03/29/2011 12:29 PM, Kyriakos Zarifis wrote: > > Hi Karim, > > the second parameter of install_datapath_flow() is a python dictionary > that describes the flow for which you are setting up an entry.
