Are you talking about a solution for storing a large number of OID/value
pairs, or a solution for compressing OIDs in PDUs?
I think your idea could work well for local storage on the manager side,
and that would be an implementation issue, and wouldn't require any changes
I don't think it would work so well for over the wire PDU OID compression.
One problem I see with this is that the manager and agent would have to
agree on the mapping in advance. This means there would have to be either
a) a machine parseable mib-oid mapping document provided by the vendor
b) a mib table on the agent providing the mapping
c) a centralized authority (ala IANA) for all mibs.
(c) is unlikely, (b) would place to much burden on small agents, both (a)
and (b) would require the manager to maintain a separate mapping for each
agent or mib.
