Our recently added [CONN_BW events](https://gitweb.torproject.org/torspec.git/commitdiff/6f2919a) include a ConnType enumeration, but doesn't really describe it. You can mostly guess their meanings, but questions off the top of my head include... * Is OR connections both client and inter-tor relay traffic? * Is DIR for both mirroring and retrieving descriptors? Personally I'd suggest breaking the type down more to be 'CLIENT / RELAY / EXIT / DIR / DIR_MIRROR' but that's up to Karsten.
