Persistent/impervious event forwarding discriminator

DETAILED DESCRIPTION It is an object of this invention to provide an EFD that is persistent in the face of catastrophic failures in the system and impervious to security breaches by rogue OSI managers.
In accordance with this invention the above problems have been solved and the above and other objects have been accomplished by providing a new EFD named the persistent/impervious event forwarding discriminator (PI EFD).
The PI EFD is monitored by the agent infrastructure in such a way that if the agent goes down, and thus the PI EFD goes down, the agent rebuilds or restores the PI EFD with all its attributes.
The PI EFD immediately creates an event notification indicating a create PI EFD event has occurred.
This event notification is of the type passed by the PI EFD to its manager.
The manager then knows the poll its other EFDs at the agent and recreate them as necessary.
To foil rogue managers, the PI EFD can not be deleted by other managers.
Further, the PI EFD cannot be locked out.
Also, the PI EFD has limited attributes that can be changed.
A rogue manager can only add himself to the destination list; it can not otherwise change the attributes of the PI EFD.
Other objects, advantages and features of the invention will be understood by those of ordinary skill in the art after referring to the complete written description of the preferred embodiments in conjunction with the following drawings.
