A telecommunication system employs dynamic shaping across a plurality of access modules of an access node using a dynamic bandwidth allocation (DBA) algorithm that is based on current load conditions for each of the access modules in order to achieve a fair allocation of network bandwidth at the access node. In one exemplary embodiment, access modules at an access node communicate via a control channel with shaper control logic that receives load information from each of the access modules. Using such load information, the shaper control logic dynamically controls the shaper rates for the access modules so that a fair allocation of network bandwidth is achieved across all of the access modules. Specifically, the shaper rates are controlled such that packet flows for services of the same class achieve the same or similar performance (e.g., average data rate) regardless of which access module is communicating each respective packet flow.
