what the definition of the "flow state" is? I am not very clear about
the content of "flow state" and there is no definition in the RFC3697.
I assume you have read the definition of "flow" at the beginning
of section 1.
"State" or "state information" in the IETF usually means the set of
data held by a node to describe a communications session. So in this case,
a possible definition of flow state would be:
The set of data held by a node to describe a flow as defined in section 1.
I'm sorry we didn't include a definition in the RFC.
As the RFC says, it doesn't describe any mechanisms for establishing
flow state, and therefore it doesn't need to describe the data either.
But I would assume that the flow state will always include at least
Flow label value
Source address
Destination address
with the rest depending on the way the flow label is being used.
Hope this helps.
