  • Adaptive resource management in a communication system
    Patent number: 7009939
    Abstract: Methods and apparatus for allocating a system resource in a communication system having an interconnected set of modules and for which the system resource is allocated among the modules are disclosed. The interconnected set of modules may be a multi-shelf daisy-chained DSL access multiplexer (DSLAM), with each of the modules corresponding to a particular shelf of the DSLAM. The system resource is initially allocated among the modules in accordance with a predetermined allocation, e.g., a reserve pool is established with a first portion of the system resource and the remaining portion of the system resource is equally divided among the interconnected modules. The allocation of the system resource is then periodically updated based at least in part on measured characteristics of at least a subset of the modules, the measured characteristics being indicative of utilization of the initial allocation.
