That won't help. Think about it this way. A session state log entry is roughly 512 bytes. [math redacted] you're still looking at roughly 85 Petabytes of storage required to meet CALEA standards.

I've done my share of shoveling dirt on the CGN coffin, but in the interest of fact-based decision-making: nobody is going to create a separate log entry for every session/flow. You do bulk port assignment or deterministic NAT, so whenever you assign an address, you know what ports you'll be mapping that address to. One entry per Lease_Time. Doesn't matter, because the servers aren't logging port number, so nobody will ever need to see those logs. * Unless Geoff Huston's wackiness finds support, and somebody will pay you to keep that kind of log. Although if somebody would pay, I'd expect them to be paying for DPI deployment already.
