Examples that come to mind are when the subagent is functioning as a gateway to some other subagent protocol, bridging to a transport protocol not supported by the master agent implementation, or both. I suppose it could come in handy with a connectionless subagent transport, but that seems to me to be a bit of a stretch. There might be other uses, but I've been away from this stuff for a long time. > I've written a sub-agent implementation whose code and API would be > simpler if it would limit users to a single session per connection, There really isn't much reason to expose session ID in a subagent API. Assuming you have some kind of constructor that returns a session object, the session ID would be private data that only the library, and not the user code, would ever have to llok at. > and I am wondering what benefits it would deprive them of by doing so. > As you might guess, I'm hard pressed to come up with use cases myself > -- I must be missing something. > I'm not exactly an SNMP expert, my apologies if this is a silly question. > > Thanks in advance. Not silly at all. As I recall, this was a "borderline" feature of the protocol, dating from a time when lots of things other than AgentX were in use, and the need to be able to build ways to support legacy subagents was a real concern.
