An API including a registration function and a configuration function, is provided to an optical networking apparatus to facilitate registration of configuration specification delimiter pairs by service routines of function blocks of multi-protocol optical networking modules (MPONM), and extraction of configuration specifications for the function blocks from a configuration specification input set using the registered configuration specification delimiter pairs. In one embodiment, the configuration function also receives current configuration of the function blocks, and merges the received current configurations of the function blocks into a configuration specification output set, separating the merged configuration specification using the registered configuration specification delimiters.

An API is provided to an optical networking apparatus to facilitate uniform access, control and interaction with its multi-protocol optical networking modules (MPONM) by its applications. Each of the MPONM has a number of function blocks having corresponding drivers. In response to an application's request to initialize a MPONM, the initialization function of the API cooperates with the function block drivers to create a data structure for the MPONM, and returns a handle of the data structure to the application. Thereafter, in response to a need to have an operation performed in the packet filtering function block of a MPONM, the application makes the request to the API, including with the request the handle of the data structure of the MPONM. In response, the API allocates a packet filtering resource to perform the operation, and returns a handle corresponding to the allocated resource to the application for use in further requests. When the application is finished with the resource, the resource is de-allocated by the API.

An API including an interrupt handler registration function and one or more interrupt dispatchers, is provided to an optical networking apparatus to facilitate registration of interrupt handlers to handle interrupts triggered by the function blocks of multi-protocol optical networking modules (MPONM). Each registered interrupt handler may handle interrupts triggered by one or more function blocks of any of the MPONM, and/or for one or more cause. In one embodiment, the one or more interrupt dispatchers are equipped to determine the triggering function block and the cause, and determine the interrupt handlers, if any, are to be notified. Each of the interrupt handlers to be notified is notified accordingly, including the triggering function block and the cause.
