The goal of this working group is to define standards-track technology for SNMP Agent extensibility. The resulting technology specification will allow independently developed sub-agents to communicate with a master-agent running on an Internet device.
The technology specification will consist of:
o (mandatory) a platform-independent protocol which supports intra-agent communication within a device or local area network;
o (optional) a MIB module, which, when implemented by a master-agent, allows an SNMP-based management application to monitor and control the intra-agent communication service; and,
o (optional) a programmatic interface to the services offered by that protocol.
The working group is explicitly directed to develop a solution which is adequate to achieve transparency with respect to whether a SNMP request is processed by a master-agent and/or one or more sub-agents; simultaneously, the working group is further directed to use good engineering judgement is developing an approach with the smallest reasonable "footprint" to achieve intra-agent communication. As a consequence, if the working group may choose to avoid complete transparency, if, at its discretion, this proves too costly. In this case, the working group should document its decision for this engineering trade-off.
Although the working group will solicit existing specifications and experience in this area, it will produce a vendor-neutral technology specification.
