Hi
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
- I believe these Metadata Values are determined by the ODL
- Do we have certain *rule/ Algorithm *, to determine these Metadata
from a Packet.
Because the Actual Packet in OVS is actually switched based on Matching
Metadata, Is that correct ?? ( Atleast according to the rule )
And the Packet itself does not carry the Metadata.
- Then how exactly the packet hitting a flow matched against the
Metadata.
- If I understood it correctly the Packets those are traversed between
the flow, 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.
- 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.
Thanks for your time, and clarification, and sorry if it is too much.
