Re: New Version Notification for draft-maglione-radext-ipv6-acct-extensions-00
Why do you need separate counters for IPv6?
Is it because you want to have different counters for different IP technology at the same time in the accounting stream?
If yes there are other problems with that approach. Accounting is used for both volume and time accounting. While having distinct volume counters for one technology may solve the volume aspect it does not address the time aspect. Consider the fact that even if you have both IPv4 and IPv6 enabled one may start at a different time then the other and one may stop at a different time then the other.
There are other information elements that are accounted for that may be specific to a particular IP technology and not the other.
As well, a user may have multiple IPv4 addresses and multiple IPv6 addresses.
So I am concerned that you are not really addressing all the issues.
Separate accounting streams per IP session solves these problems.
What is the problem with having separate accounting streams per IP session?
