Abstract
Systems which utilize a series of managers to handle resource management. Three types of managers are preferably used, with each manager being in one of two states, active or available. The types of managers are Global Interface Manager (GIM), Resource Manager (RM) and Access Manager (AM). Associated with each device driver for a given function is a GIM. The device driver may be associated with one or more RMs and/or AMs. Among managers of a given type, one is the active manager and all other managers of that specific type are available and work with the active manager to handle resource requests. As there can be RMs for different resources, the active manager concept is applied to the RMs associated with each resource. Mechanisms are present to allow the active manager and related information to be transferred to an available manager if necessary.
