Abstract: Process to associate a set of physical ports on a physical device with a set of software virtual interfaces. Process includes placing the set of software virtual interfaces to be associated with a set of N physical ports in an enabled state which has a first link state when no activation device is connected to a particular software virtual interface and a second link state when an activation device is connected to the particular software virtual interface. Connecting an activation device such as a loopback connector to a physical port to shift the software virtual interface to the second link state to map that particular physical port to that particular software virtual interface.

Abstract: A method for creating an optical binary digital transmit signal to be supplied to an optical transmission link including: operating an optical transmitter in such a state that mode hopping occurs between a predefined first and a predefined second optical mode of the optical transmitter if a binary digital modulation signal is supplied to the optical transmitter and creating a modulated optical output signal of the optical transmitter corresponding to the binary digital modulation signal supplied to the optical transmitter. The modulated optical output signal is optically filtered in such a way that at least a portion of the optical power spectrum of the modulated optical output signal caused by a selected one of the first and second optical modes is suppressed or at least substantially attenuated.

Abstract: A method for allocating a fixed number of resources of a first type within a compute platform. Allocating a set of at least one resource of the first type as targeted resources; the targeted resources available for management workloads when not activated for use by productive workloads. Assigning a set of management workloads to a first targeted resource while the first targeted resource is not activated for use by productive workloads. Processing management workloads on the first targeted resource. Responding to an opportunity to use the first targeted resource for productive workloads instead of continued use for management workloads by ceasing processing of management workloads on the first targeted resource and activating the first targeted resource for use by productive workloads and making the first targeted resource unavailable for management workloads until deactivated.
