A scalable and programmable modular queue manager architecture

The constantly changing nature of network traffic means that scalable and programmable traffic management (TM) in the form of a queue manager (QM) is becoming vital for realizing quality of service (QoS) in next generation networks. Typical QM solutions are proprietary with fixed architectures and costly management of queues. In this paper, we present a new FPGA- based QM architecture which is able to efficiently manage memory resources at high speed, thereby allowing the creation of flexible, scalable TM systems that can adapt to changing network conditions.
