Abstract

The invention provides a method and device for predicting the real-time flux and a method and device for monitoring and alarming the real-time flux. The method for predicting the real-time flux comprises the following steps: step S102 of obtaining the real-time flux information in given cycle from port or link and determining an average of flux in given cycle and an average of flux at a special time in given cycle; step S104 of setting a first weight for the average of flux in given cycle based on flux characteristic of different service and setting a second weight for the average of flux at a special time in given cycle, based on flux characteristic of different service; and step S106 of weighted averaging the average of flux in given cycle and the average of flux at a special time in given cycle to obtain the predicted flux of port or link at a special time in given cycle.

Description

technical field [0001] The invention relates to the technical field of network flow analysis, in particular to a real-time flow prediction method and a real-time flow detection and early warning method and device. Background technique [0002] Traffic models are very important for network performance analysis, network planning and design, network load balancing, and discovery of network anomalies. With the increasing development of Internet applications, the scale of the network is also increasing, and the operation status of the network and possible problems have become more and more concerned issues. [0003] Most of the previous traffic models borrowed from the traffic model of the PSTN network, and used the Poisson model to describe the traffic model of the data network, also known as the classic model. Its three main assumptions are: [0004] 1. The time interval at which data sources generate traffic is exponentially distributed, that is to say, the generation of data...
