Abstract: A component based Application Middleware Framework (20) for modifying Application Middleware Framework (AMF) component services includes an interceptor (70) for intercepting an interface event being transmitted from a software management application (14a-14e) to a software component (40, 42). A rules database (48, 78) stores AMF component service modifying rules, and an adaptor (72) modifies the interface event based on the AMF component service modifying rules stored in the rules database (48, 70). A policy engine (74) attempts to match the interface event with the AMF component service modifying rules stored in the rules database (48, 70), and subsequently coordinates the modification of the AMF component service by the adaptor (72) when the policy engine (74) matches the interface event with at least one of the AMF component service modifying rules stored in the rules database (48, 70).

Abstract: A cable communication system (100) where a control unit (110) sends operation parameters to subscriber units (130) and the subscriber units (130) respond by modifying the method of communication. Also, the subscriber units (130) send messages which include information on the subscriber unit (130) and the capabilities of the subscriber unit (130). Furthermore, the control unit (110) efficiently manages the system 100 by monitoring the capabilities and instructing the subscriber units (130) on-how to communicate on the system (100). Such management allows for the migration of subscriber units (170) from one service area (140) to another (190) without the disruption of service. In addition, initialization of subscriber units (130) may be accomplished over the cable and does not require an operator at the subscriber location.

Abstract: Frequency spectrum management provides for dynamic spectrum usage adjustment among applications on a shared medium. Dynamic resource management methods are applied to the problem of managing spectrum and matching application specific requirements to real-time spectrum characteristics so that more optimal use of the available spectrum may be made. At least a first spectrum agent is assigned to each of the plurality of different applications, for managing channels allocated to the application, and a spectrum manager allocates frequency channels to the plurality of different applications based on the following at least one of parameters of a frequency channel required to implement the application and predetermined requirements based on time of day demand changes for the application.
