<p>A resource manager is operable to control the allocation of a resource to competing computing processes. The resource manager responds to a request from a requesting process for allocation of the resource and, when the resource is currently allocated to another process, it provides an indication to the requesting process of the expected time before the resource will become available. The expected time indication can be derived, for example, by requesting information from a process to which the resource is currently allocated, or by heuristic methods, or by a combination of both. In a telecommunications apparatus, the processes can be applications requiring access to a telephony resource, for example a modem. The applications are implemented as objects, in particular beans, in an object oriented environment whereby the resource manager is able to ascertain parameters from the objects. <IMAGE></p> |
