Updateable event forwarding discriminator incorporating a runtime modifiable filter

摘要

A method for updating an updateable event forwarding discriminator (UEFD) with a filter object. The filter object can be created and instantiated within the UEFD during continued operation of the UEFD. The method can further include the steps of defining a filter algorithm text string, incorporating the filter algorithm text string into a filter class template, and compiling the filter class template to create the filter object. The filter algorithm can be simple or complex. A preexisting filter object can be de-referenced immediately prior to instantiating the filter object. Provisions can be incorporated for automatically checking type and syntax of the filter algorithm text string to identify one or more errors and providing an output error signal in the case that the one or more errors are identified. The UEFD can incorporate multiple filter parameters. A method for managing at least one event forwarding discriminator is provided. A filter algorithm can be received via SNMP or other management protocols from a subscriber and used to create a filter object, an event forwarding discriminator shell can be created, and the filter object can be instantiated within the event forwarding shell to create a UEFD. The UEFD can have an identification relating the UEFD to the subscriber. The subscriber can then update the UEFD when desired.
