A network adaptive traffic shaping method and system

Abstract

The present invention provides a network adaptive traffic shaping method and device. The method includes S1: setting relevant configuration parameters through a user-mode tc command, and enabling a dynamic traffic shaping function; S2: collecting the entry io rate of a cache queue, and calculating the rate within a period of time S3: Calculate the new token issuance rate according to the current ingress io rate, token issuance rate, buffer queue length and delay information of packets in the buffer queue; S4: According to the new token issuance rate and the current There is a rate to judge whether the rate adjustment needs to be performed, and the real-time adjustment takes effect if the adjustment is required. The present invention collects the rate of the ingress traffic of the network card in real time, counts the change trend of the ingress rate of the network card, and dynamically adjusts the issuing rate of the token, so that it can be adaptive according to the traffic, and at the same time, it can smooth the sudden network io, and can monitor the loss of the network card. Packet situation, realize the shaping scheme that reduces packet loss and dynamically adjusts according to real-time traffic.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a network adaptive traffic shaping method and system. Background technique [0002] Traffic shaping is a network traffic management technology that sends jittered traffic packets at a relatively uniform rate. Currently, there are two core traffic shaping algorithms: [0003] Leaky bucket algorithm: [0004] The leaky bucket algorithm is an algorithm often used in Traffic Shaping or Rate Limiting. Its main purpose is to control the rate at which data is injected into the network to smooth out burst traffic on the network. The leaky bucket algorithm provides a mechanism by which burst traffic can be shaped to provide a stable flow to the network. [0005] A leaky bucket can be thought of as a single-server queue with a constant service time, if the leaky bucket (packet buffer) overflows, packets are dropped. In the network, the leaky bucket algorithm can control...

Problems solved by technology

However, in essence, the token bucket algorithm and the leaky bucket algorithm are still the same. In the case of a fixed traffic threshold, it is difficult to achieve traffic shaping when the traffic is low, and it is easy to cause packet loss in the case of high traffic.
