Adaptive resource management in a communication system

A method 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 models, the method comprising the steps of:

• initially allocating the system resource among the modules in accordance with a predetermined allocation and establishing a reserve pool with a first portion of the system resource and equally dividing a remaining portion of the system resource among the interconnected modules;
• and
• periodically updating the allocation of the system resource 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;
• wherein the interconnected set of modules comprises a multi-shelf daisy-chained DSL access multiplexer (DSLAM), with each of the modules corresponding to a particular shelf of the DSLAM.

An apparatus for use in 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, the apparatus comprising:

• at least one processor operative to initially allocate the system resource among the modules in accordance with a predetermined allocation, and to periodically update the allocation of the system resource based at least in part on measured utilization history information of at least a subset of the modules, the measured utilization history information being indicative of utilization of the initial allocation;
• and
• a memory coupled to the processor for storing information associated with allocation of the system resource;
• wherein the interconnected set of modules comprises a multi-shelf daisy-chained DSL access multiplexer (DSLAM), with each of the modules corresponding to a particular shelf of the DSLAM.

A machine-readable medium storing one or more programs for use in 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, wherein the one or more programs when executed by a processor implement the steps of:

• initially allocating the system resource among the modules in accordance with a predetermined allocation;
• and
• periodically updating the allocation of the system resource based at least in part on measured utilization history information of at least a subset of the modules, the measured utilization history information being indicative of utilization of the initial allocation;
• wherein the interconnected set of modules comprises a multi-shelf daisy-chained DSL access multiplexer (DSLAM), with each of the modules corresponding to a particular shelf of the DSLAM.
