The Simple Network Management Protocol (SNMP) [1] Distributed Program Interface (DPI) is an extension to SNMP agents that permits end-users to dynamically add, delete or replace management variables in the local Management Information Base without requiring recompilation of the SNMP agent. This is achieved by writing a so-called sub-agent that communicates with the agent via the SNMP-DPI.
For the author of a sub-agent, the SNMP-DPI eliminates the need to know the details of ASN.1 [2] or SNMP PDU (Protocol Data Unit) encoding/decoding [1, 3].
This protocol has been in use within IBM since 1989 and is included in the SNMP agents for VM, MVS and OS/2.
Potentially useful sample sub-agent code and implementation examples are available for anonymous FTP from the University of Toronto.
