I guess that I would probably implement a new ofproto provider that includes the features that you can support. You can register your new ofproto provider by inserting a call to ofproto_class_register() into ofproto_initialize(), in ofproto/ofproto.c. On Sat, Jan 28, 2012 at 07:10:45PM +0100, Gio

Hello Ben, Yes, you're definitely right! But this is not about implementing OpenFlow: I just want to realize a management interface translation for the features that is possible to translate (e.g. port statistics retrieval). Is up to the legacy network device to provide switching, routing, VLAN ta

Dear all, I would like to use Open vSwitch for the monitoring/control of a legacy data plane (i.e. with no support to OpenFlow). The idea is to extend OVS to make it an adapter between the OpenFlow protocol (used by the control plane) and SNMP (exposed by the underlying network devices). I'm evalua
