A method and system for restoring data redundancy in a storage system without a hot standby disk is disclosed. A splitter is installed between these two rare earth-doped optical fibers. The value of the protocol extension field indicates whether or not the packet header has been altered: 00 indicates no alterations, 01 or 10 indicate a predetermined change in the content andor length of the header, and 11 indicates dynamic negotiation of the field values andor size. Using the resoswitch, power amplifiers and converters more closely approaching ideal may be implemented. Routing of a digital object may be based in part on link quality on the network andor a desired level of quality andor service. Operational resource modeling involves creating and training one or more resource models, andor simulating hypothetical scenarios using resource models.
