Abstract: A system assigns, to selected network devices in an intelligent transport network, a policy domain marker that identifies a particular network operation policy. The network devices that receive the policy domain marker delineate a region of enforcement for the particular policy. After an appropriate waiting period to permit the selected network devices to advertise their policy domain marker, the system distributes, to all network devices in the intelligent transport network that support control plane signaling or control plane routing, an enforcement signal to enforce the particular network operation policy for the delineated region.

Abstract: To select a master controller from a plurality of controllers, a computing system may consider whether connections between components within field replaceable units (FRUs) are functional as well as the data dependencies between the FRUs. For example, in addition to identifying whether the connections between the FRUs and the controllers are functional, the computing system sends instructions to each of the FRUs coupled to the controllers to determine if inter- and intra-FRU connections required for booting a compute node hosting the FRUs are functional. For instance, one FRU may depend on data from another FRU in order to boot. If a communication link between the FRUs is non-functional, the compute node may fail to boot. The computer system uses these evaluations to determine which of the controllers to select as the master.

Abstract: An interface accesses a server for managing usage of a plurality of frequency resources allocated to a first wireless system and acquires information indicating the usage. Based on the acquired information, a control unit selects, amongst the frequency resources, a frequency resource to be used by a second wireless system.

If the reacquisition is unsuccessful, the control unit allows a frequency resource for the second wireless system to be selected based on the information acquired at the first time point even from the second time point onward.
