  • Patent number: 8339950
    Abstract: A queue processing method and a router perform cache update and queue processing based upon whether or not the packet capacity stored in the queue exceeds a rising threshold, or whether the packet capacity stored in the queue is below a falling threshold after the packet capacity stored in the queue has exceeded the rising threshold. This queue processing method and router makes it possible to eliminate overhead associated with the update of flow information by using two caches, while concomitantly removing the inequality of packet flows via RED queue management with the expedient of using two caches.
