Is there something particular that you're trying to achieve which
standard OpenFlow cookies do not provide?

The OVS datapath extracts the packet headers then looks for a match in
its flow table. What part of that is the "flow index"?

Hi Ben,
So, I am reading how OVS datapath works... don't see the details but read
the following (which I had read before as well):
- A flow may be identified by any combination of ... (tunnel id, ipv6 nd
target, ipv4/6 src addr, ip4/6 dst addr, ... etc.)
- The first packet of the flow is sent to
Okay. How does the OVS datapath know this is a new flow? i.e. there is no
matching flow entry? Doesn't it derive some sort of an index (into the flow
table) from packet header fields? What am I missing? :)
If this is explained in details somewhere, I would appreciate the pointer.
Thanks,
ashok

Perhaps once you understand, it will make sense? :)
Call it whatever flow_id or cookie or xyz? Let me call it "flow index" for
the sake of this discussion. The ovs datapath has some sort of a flow index
to look into the flow table when a packet arrives, right? Now, how does the
ovs datapath arrive

Hi,
Could someone please let me know if my request can be accomodated...
I have asked a few times for this before, but I'll ask again:
Basically, I need a new ofp_type support... something like
OFPT_GET_FLOWID_REQUEST and OFPT_GET_FLOWID_RESPONSE.
