Network delay detection method, device and system

Abstract

The embodiment of the invention provides a network time delay detection method, device and system, and the method comprises the steps: transmitting a request echo message to a receiving end, and transmitting detection information detected by a plurality of detection points in the transmission process of the request echo message; receiving a response echo message returned by the receiving end, wherein the response echo message carries detection information detected by the plurality of detection points in the process of transmitting the request echo message and detection information detected by the plurality of detection points in the return process; and the network time delay is determined according to the detection information in the response echo message. Time synchronization is not needed, and flexible addition and deletion of various detection points are supported, so that flexible diagnosis of network time delay is realized; the method can solve the problem of delay of fine-grained analysis, especially for fine-grained analysis of a sending end and / or a receiving end, deployment is flexible, data analysis is decentralized, data does not need to be uploaded to a central node, and the method does not depend on a complex analysis system.

Description

technical field [0001] The embodiment of this specification relates to the field of computer technology, and in particular to a method for detecting network delay. Background technique [0002] With the rapid development of computer technology, the network has been widely used. Measuring and evaluating network performance is an important part of network operation and maintenance, and network delay analysis is the most critical. However, the link complexity of the network is high. In the cloud environment, the transmission of a message will go through various complicated transmission paths and intermediate nodes; the problem of network delay and jitter is difficult to locate, and the positioning time is long. In the process, any tiny factor may cause jitter in the transmission delay of the packet. These problems make the demarcation of network delay very difficult, and it is impossible to achieve fine-grained demarcation of network delay, and it usually needs to rely on mec...

However, the link complexity of the network is high. In the cloud environment, the transmission of a message will go through various complicated transmission paths and intermediate nodes; the delay and jitter of the network is difficult to locate, and the positioning time is long. Any tiny factor may cause jitter in the transmission delay of the message

These problems make the demarcation of network delay very difficult, and it is impossible to achieve fine-grained demarcation of network delay, and usually need to rely on time synchronization, centralized data collection and analysis system and other mechanisms
