[ippm] RE: [PMOL] Draft Charter for discussion
Hi Al,
Is the WG pmol created in the transport area?
To take in account the last IPPM meeting output, I will remove the passive metrics stuffs from http://tools.ietf.org/html/draft-ietf-ippm-multimetrics-04. These performance metrics are performed on real applications traffic transported by IETF-specified protocols. Are they an emanation of PSAMP WG or of the (IETF-specified) protocol actually observed?
Regards
Emile
