Re: [eman] two questions to draft-claise-power-management-arch-02 draft

The power levels are designed to be sparse.   So, your platform can implement those EMAN levels 1..12 which made sense for it.  Figure 6 of the EMAN Framework v-01 gives an example of this mapping to a device supporting four fictitious power states:

              Power State / Name       Manufacturer Power State / Name
               1 / Mech Off             0 / none
               2 / Soft Off             0 / none
               3 / Hibernate            0 / none
               4 / Sleep, Save-to-RAM   0 / none
               5 / Standby              0 / none
               6 / Ready                1 / short
               7 / LowMinus             1 / short
               8 / Low                  1 / short
               9 / MediumMinus          2 / tall
               10 / Medium              2 / tall
               11 / HighMinus           3 / grande
               12 / High                4 / venti

                          Figure 6: Mapping Example 3

This is similar to the DMTF and ACPI models which define many states, but devices are not required to implement them all.

Thanks for your answer!

I recognize that other protocols besides SNMP are not in our scope from your answer.

But how about the second question? Would you like to give us an answer?



Thanks!

Yes, the EMAN data model uses the Simple Network Management Protocol (SNMP).  Our draft management information base (MIB) inherits data types and textual conventions from the SNMP standard.  It’s not really adaptable to other protocols that don’t support SNMP data types.

There is no standard data format for FTP, hence its not useful by itself as a data transfer protocol without another layer of interpretation such as an XML schema or CSV format.  As for the other protocols you mention, they seem to be domain specific, but I’m not familiar with them.

Regards,

Brad Schoening

1,The protocol between NMS and device is SNMP, but how about other protocol, such as FTP, TL1 or Qx ?  Is these protocol prohibited  or out of eman's scope?  Now lots of SDH, MSTP devices is managed by NMS in protocol Qx or TL1. Also, lots of core network device is  managed by NMS in protocol MML, and so on.  Will our draft fit for these devices(wireless device, core network device, transfer device )?

2,The power level is defind in the draft is [0...12], how will we use it? All device must have all the power level? or different NE can select different part of them. For example, A can select [0...7], B can select [8,10,12], and so on.



How about other memeber's thought?
