The invention comprises a method and system to support dynamic allocation of traffic management resources in a network element. Shared pools of traffic management resources, comprising an aggregation of local line card resources hosted by various line cards, are distributed across line cards (blades) of a network element. Incoming packets are classified into subscriber flows, usin g a hierarchical classification scheme. In view of subscriber services and flo w application types, traffic management resources are dynamically allocated fr om the shared pools, and traffic management policies associated with the subscriber services and application types are applied to the subscriber flow s via the allocated resources. In response to detection that a subscriber flow has terminated, the allocated resources are released, and made available to be dynamically re-allocated to subsequent subscriber flows. |
