scu/dcu — Truman Boyes

Been working with source-class-usage and destination-class-usage (SCU/DCU) for some recent project work; it is pretty cool what you can do with JUNOS policy to accomplish some complex data accounting based on pretty much anything. For example, it is possible to tag BGP communities against some particular routes, then you can create source class usage or destination class usage datasets when traffic either comes from those prefixes or is destined to those prefixes or you can get data for both directions.

Also, been hacking away on some IPv6 accounting with SCU/DCU, found an issue or two but still working through it.
