Abstract:
1. A system for managing transfer of communication traffic between communication traffic management devices which employ respective communication traffic management schemes, a first one of the communication traffic management devices being capable of transferring communication traffic to a second one of the communication traffic management devices, the system comprising: a queue threshold status detector configured to determine whether an amount of communication traffic currently stored in a communication traffic queue of the second communication traffic management device exceeds a threshold; and a transfer rate control module operatively coupled to the queue threshold status detector and configured to apply transfer rate control to the first communication traffic management device, based on whether the amount of communication traffic exceeds the threshold, to control a rate of transfer of communication traffic to the second communication traffic management device, wherein: the first communication traffic management device comprises an Internet Protocol (IP) communication traffic management device, and wherein the second communication traffic management device comprises an Asynchronous Transfer Mode (ATM) communication traffic management device; the IP communication traffic management device comprises a plurality of queues for storing communication traffic received from at least one communication traffic source; the ATM communication traffic management device comprises a plurality of queues for storing communication traffic received from at least one corresponding queue in the plurality of queues of the IP communication traffic management device for transmission on respective Virtual Circuits (VCs); the queue threshold status detector is configured to determine whether an amount of communication traffic currently stored in a communication traffic queue of the second communication traffic management device exceeds a threshold by determining, for each of at least one of the plurality of queues of the ATM communication traffic management device, whether the amount of communication traffic currently stored in the queue exceeds a respective threshold associated with the queue; and the transfer rate control module is configured to apply transfer rate control to the IP communication traffic management device, based on whether the amount of communication traffic stored in each of the at least one queue exceeds the threshold associated with the queue, to control a rate of transfer of communication traffic to the ATM communication traffic management device from the at least one corresponding queue of the plurality of queues of the IP communication traffic management device.
