Abstract

The invention discloses a method and a device for supervising traffic based on a token bucket. The device comprises a setting module, a memory, a control module and a traffic supervising module. The corresponding method comprises the following steps that: 1) setting different leaky bucket algorithm rules, and establishing a mapping relationship table between stream IDs and the leaky bucket algorithm rules; and 2) acquiring a message to be supervised; searching for the corresponding leaky bucket algorithm rule and a leaky bucket parameter by using a stream ID as an index; accordingly determining the number of available tokens in the current average leaky bucket and the peak leaky bucket; comparing the length of the message with the number of the available tokens in the current average leaky bucket and the peak leaky bucket respectively; coloring the message by adopting a corresponding leaky bucket algorithm rule and according to the comparison result; updating and storing the leaky bucket parameter serving as a standby parameter for processing the next stage of message with the same stream ID; and then discarding or forwarding the message according to the coloring result. The method and the device simultaneously support a single-rate marker algorithm and a double-rate marker algorithm, have excellent compatibility, break through the bottle neck of processing capacity and have high processing rate.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a token bucket-based flow monitoring method and equipment applied in a passive optical network (GPON). Background technique [0002] With the development of the Internet, IP services continue to grow rapidly. GPON technology has received widespread attention. It supports traditional telecommunication services in the original format with unprecedented economy, and also supports the future evolution to all-packet / all-IP networks. [0003] How to improve the quality (QoS) of information in transmission is also a key point. QoS technology is to provide end-to-end service quality assurance for user services, and has become a research hotspot in the industry in recent years. Currently there are many QoS service models, among which the most widely used is the differentiated service model (DiffServ). The DiffServ model implements quality of service control through packet classificatio...
