Problems solved by technology

[0004] However, querying the predicted data requires memory resources, and the amount of predicted data is usually large. If the cached amount of predicted data is large, it will easily lead to memory overflow.

Embodiment Construction

[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] CDN network is a commonly used information distribution network. The network quality of CDN network directly affects the efficiency and reliability of information distribution. Therefore, it is necessary to monitor various indicators related to network quality. Usually, when monitoring network quality, network indicator data in various dimensions are monitored and alarms are issued for abnormal values.

[0034] However, in actual work, due to the following two situations, the network indicators fluctuate greatly; ...

Abstract

The invention provides a network anomaly detection method and device and a server. The method comprises the following steps: receiving a data stream of predicted data of a network index corresponding to a specified time and a data stream of actual data of the network index corresponding to the specified time; and comparing the data stream of the received prediction data with the data stream of the actual data to obtain a comparison result of the network indexes. According to the method, specified time is set in advance, when the specified time is reached, a data stream of prediction data and a data stream of actual data of a network index corresponding to the specified time are received and are compared, the prediction data and the actual data are gradually extracted in the time dimension, and the comparison is carried out in the form of the data streams, and a large amount of prediction data does not need to be cached, so that memory pressure is relieved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a network anomaly detection method, device and server. Background technique [0002] CDN (Content Delivery Network) network is a commonly used information distribution network. The network quality of the CDN network directly affects the efficiency and reliability of information distribution. Therefore, it is necessary to carry out various indicators related to network quality. Monitoring, network indicators such as error code, failure rate, bandwidth, packet loss rate, packet sending time, etc. Through monitoring, network abnormalities can be discovered and dealt with in time to ensure the normal operation of the CDN network. [0003] In one of the methods, it is necessary to obtain the forecast data of the network indicators first, which can be the forecast data obtained by predicting the indicators based on the historical network indicator data using a preset algorithm, a...
