Re: [EFM] Re: OAM - To side-band or not to side-band


The moment that you say minimum and maximums, you have said that it is not 
deterministic from the service provider viewpoint for any kind of service 
than "Internet" related.  Deterministic means that at any   specific 
granular time frame, a specific level of performance monitoring is 
available.  On today's infrastructure, where it is managed at all, that 
time frame is measured in microseconds.  Where infrastructure is not 
managed, the facility is managed through the services using  SNMP embedded 
in the customer revenue stream.  Sometimes ATM is used to create an 
dedicated channel at L2 for the SNMP, but it is still embedded as part of 
the service revenue stream.  I think that we have agreed that the 802.3ah 
OAM will not be taking that approach.
