Embodiment Construction

[0018] Embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0019] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0020] figure 1 It is a schematic diagram of the token consumption process using the WFQ algorithm. Use WFQ or similar algorithms to realize queue shaping, and you can use linked list or index form to add tokens to the queues that need to be served at the current moment in turn. Wherein, use RAM (Random-Access Memory, random access memory) to store the n...

Abstract

The invention discloses a traffic shaping method and device. The traffic shaping method comprises the steps of determining whether any queue needs to be aged or not by monitoring token consumption information of the queue; and when any queue in a token adding table needs to be aged, removing the queue from the token adding table, and updating the number of tokens in a token bucket of the queue toa value greater than a lower limit threshold of the token bucket. According to the traffic shaping method and device provided by the invention, quick response of shaping can be realized, and the powerconsumption is reduced.

Description

technical field [0001] The present application relates to but is not limited to the technical field of data communication, especially a traffic shaping method and device. Background technique [0002] With the rapid development of the Internet and mobile Internet, people have put forward newer, faster and more stable service requirements for the network, and the bandwidth and business access volume have increased rapidly. The guarantee of network service quality requires a network processor (Network Processor, NP) chip to improve performance in an all-round way. Among them, traffic shaping (Traffic Shaping) is a method to ensure the smooth output of the rate, ensure the stable forwarding of network data at the negotiated rate, prevent the congestion of downstream network devices, and avoid the delay, loss or even error of data packets. [0003] The traffic shaping of a common network processor chip adopts a timing adding method. Among them, a timer can be configured for ea...
