Re: [eman] EMAN-REQ: the notion of importance

["Mouli Chandramouli (moulchan)" <[e-mail]>]

Given the precedence of use of priority in other IETF MIBs, I think the value of importance is clearly illustrated. 

 

Regarding Role, it is not intended to be an IANA registry.  This concept is already used by deployments.  Should not be dismissed as not useful. 

 

If the question is – clearer description of these terms, in the requirements draft, it is possible to provide some text and also how these concepts can be useful. 

 

Thanks

Mouli

Hi,

Brad - good precedent - because it makes the "importance"
machine readable (and therefore useful).

But since EMAN (and many other IETF WGs) have consistently
backed away from any standard definition of "role" (w/ behavior
semantics that are predictable), a text string of "role" is useless
(except in a vendor- or site-specific manner - out-of-scope IMHO).

And I suggest that the "universe of things" is too diverse to lend
itself to an IANA registry of standard "role" keywords.

Cheers,
- Ira

Benoit,

 

There is a precedence for doing this on the device in the PoE MIB, rfc3621 which defines pethPsePortPowerPriority:

   pethPsePortPowerPriority OBJECT-TYPE
    SYNTAX INTEGER   {
               critical(1),
               high(2),
               low(3)
     }
    MAX-ACCESS read-write
    STATUS current
    DESCRIPTION
        "This object controls the priority of the port from the point
         of view of a power management algorithm.  The priority that
         is set by this variable could be used by a control mechanism
         that prevents over current situations by disconnecting first
         ports with lower power priority.  Ports that connect devices
         critical to the operation of the network - like the E911
         telephones ports - should be set to higher priority."
    ::= { pethPsePortEntry 7 }

Subject: [eman] EMAN-REQ: the notion of importance

 

Dear all, 

There is a discussion amongst the "EMAN requirements" authors right now about the notion of importance.
We're trying to evaluate the requirements related to the "importance".

The current draft version <http://tools.ietf.org/html/draft-ietf-eman-requirements-05>  only mentions:


5.1.2.  Context information on powered entities

   The energy management standard must provide means for retrieving and
   reporting context information on powered entities, for example, tags
   associated with a powered entity that indicate the powered entity's
   role, or importance.


So there are no justifications why the importance is required. 
The people who want this, please provide some more text/justifications

Some extra questions: 
- Is this importance specific to EMAN or is this generic also for non Energy Objects?
- Importance is important related to ...?

Regards, Benoit (as a contributor for the EMAN-REQ)
