Agent Software Design
The design of an agent is primarily dependent on the development environment you choose. But here are some 'generic' design issues to look at.
Object Instances. For speed agents should maintain object instances in memory. If the only interface to the NE is through the agent then this should not pose any problems. But if the NE can be accessed via other sources then it can be a problem keeping the instance information in sync. In most of these cases refreshing the agent at timed intervals can be a satisfactory solution for rather static attributes. But in other cases you may need to access the NE each time the agent needs to satisfy a request.
Try to use a multi-threaded environment for the agent. For generating CMIP notifications this is almost a necessity. But it can be done in single threaded applications by having very short looping intervals.
