Abstract :
A novel implementation of a tag sorting circuit for a weighted fair queueing (WFQ) enabled Internet protocol (IP) packet scheduler is presented. The design consists of a search tree, matching circuitry, and a custom memory layout. It is implemented using 130-nm silicon technology and supports quality of service (QoS) on networks at line speeds of 40 Gb/s, enabling next generation IP services to be deployed.
