[OPSAWG] 答复: Re: An SNMP Usage for RELOAD

[[e-mail]]

In short, the relation between SNMP Usage and RELOAD as follows:
SNMP Usage get a available IP address, which is used for SNMP 
communication, for snmeEngineID or NodeID or ResourceID or Manager name by 
RELOAD mechanism, such as AppAttach, Store, Fetch.
Then SNMP Usage uses this IP address for SNMP communication between SNMP 
entities by the SNMP mechanism and architecture which defined in RFC3411 
and RFC5953 and other SNMP RFCs (as depicted in the diagram below). And 
now there is little relation between SNMP Usage and RELOAD besides using 
RELOAD certificate. So we say "SNMP entities talk to each other using SNMP 
protocol on dedicated connections"


If you till have questions, please tell us. Thanks!

You are indeed using SNMP terminology, but I struggle to see how its usage 
is
the same as in RFC3411.

RELOAD defines a messaging network, on top of which run applications, 
which
RELOAD calls Usages, so when you define an SNMP Usage, you would appear to 
be
discarding most of an Architecture for SNMP as defined in RFC3411, perhaps
providing instead a gateway for functionality such as that specified in 
RFC3414;
or perhaps not, I do not find the I-D clear on this.  Thus you have

                  Application

            +-------+  +-------+  +-------+
            | SIP   |  | XMPP  |  | SNMP  |  ...
            | Usage |  | Usage |  | Usage |
            +-------+  +-------+  +-------+
         ------------------------------------------- Messaging API

                      RELOAD

but elsewhere you say
' SNMP entities talk to each other using SNMP protocol on dedicated 
connections'
which is rather different.

The I-D reads more like a wish list of requirements, than an overview,
architecture or framework.  Or perhaps it is all beyond me:-(
