Abstract
A traffic manager to manage flows to a plurality of remote physical ports. The traffic manager employs two tiers of shaping and scheduling driven by performance characteristics of the remote physical ports. By modeling the remote physical ports within the traffic manager, flows to the physical ports can be controlled to arrive at a rate the physical ports can handle. Any backup that would otherwise occur in the queue at the physical ports is instead queued in the traffic manager. In this manner, the intelligence of the traffic manager can be leveraged to provide improved quality of service with existing infrastructure.

12. A system comprising:
-
a broadband communication link;
a demultiplexer coupled to a plurality of physical ports and the broadband communication link; and
a network element coupled to the communication link, the network element modeling the plurality of physical ports and providing a two-tier hierarchy of shaping and scheduling of flows directed to the plurality of physical ports.
