Abstract:
A method of handling a pool of hardware resources within an architectural model for level 1 ISO-OSI protocol comprising two sublayers, the lowest of them (PHLR) being designed to the control functions of a common hardware platform and the highest (PHLU) being designed to the functions of the use of the hardware resources;providing the architectural model for level 1 ISO-OSI protocol such that the lowest sublayer (PHLR) does not know which is the use of the hardware resources, the highest sublayer (PHLU) does not know the implementing features of hardware resources, and the lowest sublayer (PHLR) communicates with the highest sublayer (PHLU) to provide information about the status of the hardware in use; and the lowest sublayer (PHLR) informing the highest sublayer (PHLU) of a fault in one of a plurality of hardware cards, and the PHLR and PHLU sublayers communicating in order to automatically remove the fault through the use of a previously non-configured card so that said information makes possible the replacement of a used circuit of a card in the event of a fault.
