This Question is extension of the following
OpenFlow Rule Metadata
I would like to have this clarified, on my question about Metadata Let us say, I have an Open Flow rules, as below
Cookie=0x8000001, duration=228925.445s, table=17, n_packets=350, n_bytes=32424, priority=10,metadata=0xc000f30000000000/0xffffff0000000000 actions=goto_table:19
I wanted to understand the following
Do we have certain rule/ Algorithm , to determine these Metadata from a Packet.
because the Packet in OVS is actually switched based on Matching Metadata, Is that correct ?? ( At least according to the above flow rule )
And the Packet itself does not carry the Metadata, then how exactly the packet hitting a flow matched against the Metadata.
So, If I understood it correctly the Packets those are traversed between the flow-tables, are within the OVS application itself or Handled @OVS Application level, until it had determined Egress Port So in that Case, the MetaData are handled @OVS-Application level, until the Packets is send via Egress Port.
Is this correct??
Finally which Module in ODL is responsible for determine the Metadata, and I would like to understand from the code how exactly it was done.
