Problems solved by technology

[0021] The above-mentioned message marking method of message-driven calculation token can obtain high bandwidth supervision accuracy, but when multiple streams share bandwidth, the messages of multiple streams have a certain sequence in the marking time, and The number of tokens in the token bucket is associated with the marking time. Therefore, there is a fixed difference in the number of tokens in the token bucket corresponding to the marking of multiple flow packets, and the packet marking rule is based on the packet length The result of comparing with the number of tokens. Therefore, for the packets of each flow with a fixed packet length, the chances of obtaining tokens are fixed. In extreme cases, all packets of some flows will be marked as red. , thus causing unfairness in bandwidth regulation

Abstract

The provided method for monitoring message bandwidth comprises: obtaining the current token quantity in the token bucket when labeling PRI for message; according to current token quantity, calculating the probability of abandoning PRI mark of the message; according to the abandoning probability, random labeling the abandoning PRI; then according to last labeling result, controlling the bandwidth occupancy of message. This invention can guarantee fair sharing bandwidth for multiple pieces of flow message.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a message broadband monitoring method and device thereof, and a message discard probability marking device. Background technique [0002] On the network device, monitoring the packet bandwidth input by the user is an important aspect to ensure the quality of service of the system. In order to monitor the bandwidth of user input packets, Committed Access Rate (CAR, Committed Access Rate) is the most commonly used approach. CAR compares the length of the user message with the number of tokens in the CAR token bucket to mark the message with priority for discarding, for example, marking the message as red, yellow, and green. When the system bandwidth is insufficient, the part with high discarding priority will be discarded. Level, such as red and yellow packets, to achieve the purpose of limiting the bandwidth of user input packets. [0003] Currently, there is a message ...
