Re: [OPSAWG] Fwd: New Version Notification for draft-nishizuka-cgn-deployment-considerations-00.txt

Hello authors,

Thanks for sharing your tests.
Some comments are below.

Section 5.2 provides two formulas to estimate the address multiplexing.
If the formula of static assigment is intended to align with
I-D.donley-behave-deterministic-cgn, it may be amended by adding
active subscriber's coefficient. CGN may only assign static port block
to active users.Meanwhile, log just needs to add one record for each
user.

Section 6.1 states the MCS is highly dependent with retention time of
NAT table. It would be intereted to add some discussions if CGN could
interact with PCP.

BTW, the table shown CGN sets retention time for DNS. would you do DNS
filter on CGN to identify DNS package?  I saw you also described DNS
bypass CGN. Are those related?

Many thanks

Gang
