Real-time flow packet loss state sensing method for high-speed network

Abstract

The invention provides a real-time flow packet loss state sensing method for a high-speed network. The method can detect the packet loss state of a service transmitted by using a TCP and a UDP in the high-speed network in real time. The method comprises the specific steps of model training and model use; during model training, carrying out the traffic sampling collection in a controllable network environment; according to different transmission protocols, setting a counter of the feature Sketch so as to extract effective features; and according to the extracted features, training a machine learning classification model to obtain a packet loss prediction model. When the model is used, firstly, real traffic is sampled and collected at traffic collection points in a network, and real traffic features are extracted in real time by using the feature Sketch; and a packet loss prediction model is used to identify and classify real traffic features, and a packet loss state is detected in real time. The method can be used for a network service provider to monitor the network service state on the network intermediate node in real time, and provides a basis for improving the access service quality.

Description

technical field [0001] The invention relates to a high-speed network-oriented real-time perception method and technology of packet loss state of traffic, belonging to the field of network management. Background technique [0002] In recent years, with the rapid development of the Internet, many new network services have emerged. These network services provide great convenience for people's daily life. At the same time, the stability of these services is also the key factor for people to choose network access service providers. mostly according. However, these network services may encounter different types of network attacks or communication failures, resulting in data packet loss and further affecting user service experience. Therefore, monitoring the traffic of important network services and detecting the packet loss status of service traffic in real time is of great significance for network access service providers to discover security problems and management failures in ...

AI Technical Summary

Problems solved by technology

Because of TCP's timeout retransmission mechanism, this method is often time-consuming, and must use all packet data, which cannot be used in the case of data sampling, resulting in high space and time consumption.

In addition, such methods cannot be applied to packet loss detection of UDP protocol
