Ed,

Since you volunteered for writing a draft to clarify the I1NSF terminologies, I put down some controversial terminologies I have captured:

Object vs. Contextual State: both for describing the contextual or environment for the rule sets. WG needs to agree on one terminology.

Asymmetrical vs. Direction of traffic:

Some people use "Asymmetrical" & "symmetrical" to refer to the requirement of both directions of the traffic have to go through the same path. In another word: congruent paths for both directions.

"Direction" is also used by some people to refer to one direction of traffic is allowed, where the other is not. E.g. A group can only originate traffic and can only receive traffic for the responses of their own originated traffic.

Differentiation from SFC:

SFC is about delivering traffic to the door. I2NSF is about how to treat packets delivered to my door.

I2NSF is really focusing how to treat packets, but not how the traffic is delivered to my door.

Thanks, Linda Dunbar
