Traffic policing method and device

Abstract

The invention provides a traffic policing method. In the method, configuration parameters of double token buckets and the corresponding relationship between a routing adjustment strategy and the state change of the double token buckets are preset, wherein, the double token buckets comprise a first token bucket with a low threshold and a second token bucket with a high threshold, and the speed of the first token bucket for throwing a token is lower than that of the second token bucket for throwing a token. The traffic policing method comprises the following steps: A carrying out traffic policing on services to be policed according to the configuration parameters of the double token buckets, and detecting the state of the double token buckets of the services to be policed; and B carrying out routing adjustment according to the state change of the double token buckets and the corresponding relationship between the preset routing adjustment strategy and the state change of the double token buckets. The invention further provides a traffic policing device. In the invention, routing adjustment is carried out according to the state change of the double token buckets of the services to bepoliced so as to change the circulation path of a message and realize high-performance routing based on traffic evaluation, thus achieving the purposes of enhancing the service efficiency of a link and ensuring the service quality of the services.

Description

technical field [0001] The invention relates to network communication technology, in particular to a flow monitoring method and device. Background technique [0002] Traffic monitoring, also known as committed access rate (CAR) technology, is one of the important components of the QOS technology system and an important technology for network equipment to control traffic. The existing traffic monitoring technology adopts the principle of token distribution, based on the preset traffic size, distinguishes the passing packets, and takes actions such as re-marking, passing or discarding, and prepares for other subsequent QoS actions, such as outgoing interface Remark-based QoS queue scheduling. [0003] Routing technology is the basic technology of network communication. It is a technology for finding and forwarding packets between different networks. It mainly includes static routing, dynamic routing, and policy routing. The current traffic policing technology realizes the fl...

Problems solved by technology

However, this technology has two disadvantages. First, when a video conference is held, a large number of red video packets will be generated. If the routing adjustment of data services is performed on each red packet, it will have a great impact on router performance and routing stability. The second is that if the video traffic is slightly lower than 4M in an instant, there will be no red video packets, so when should the data service be readjusted to the original forwarding strategy? If the original strategy is adjusted immediately, the video traffic will The frequent adjustment of the routing strategy of the data service caused by the fluctuation around 4M is not conducive to the stability of the routing

[0007] From the above content, it can be seen that the current traffic monitoring technology can only monitor and limit the traffic, and cannot combine the routing technology to adjust the route according to the change of the business traffic, and cannot change the circulation path of the message
