摘要： A scheduling system for IP routers is provided. A programmable scheduler for IP routers can support single stage and multistage scheduling. This allows flexible combinations of scheduling and widens dramatically the available QoS solutions to operators. With this kind of scheduling the router can be configured to support almost any known scheduling method or combination. Priority Queuing (PQ) and Deficit Round Robin (DRR) scheduling is scheduling is used according to one embodiment of the invention.

摘要： An advanced traffic shaper is provided for shaping real-time traffic in an IP-based network while simultaneously providing keep-alive bandwidth for best-effort traffic. The traffic shaper comprises a packet classifier coupled to receive an incoming packet from the network and to classify the incoming packet as one of a real-time packet and a best-effort packet; a packet discarding block coupled to perform traffic shaping of the incoming packet from the packet classifier and discard the incoming packet in accordance with traffic shaping parameters; connection queues coupled to temporary store real-time packets and best-effort packets from the packet discarding block, respectively; and a packet scheduling block coupled to send the real-time and best-effort packets from the connection queues to an outgoing device in accordance with the traffic shaping parameters.
