Network delay state detection method and device

Abstract

The invention discloses a network delay state detection method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: inserting INT message headers into a plurality of messages, and adding metadata packaged with state information of a head node switch behind the INT message headers to obtain a plurality of detection messages comprising INT data; sending the plurality of detection messages to an intermediate node, and adding metadata packaged with state information of an intermediate node switch; continuously forwardingthe plurality of detection messages to the terminal node, and adding metadata packaged with the state information of the terminal node switch; and packaging the plurality of detection messages and sending the packaged detection messages to a monitoring server to realize network delay state detection. According to the embodiment, the INT detection message is actively sent by the head node switch byconfiguring a simple sampling rule, so that the technical effects of acquiring the network delay state information and reducing the pressure of monitoring equipment are achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a detection method and device for a network delay state. Background technique [0002] The traffic carried by the current data center network is becoming more and more diversified, and the traffic load is getting heavier. Therefore, how to solve or avoid network congestion is becoming more and more critical for network forwarding devices. INT (In-band Network Telemetry, in-band network telemetry) is a new type of Telemetry (telemetry technology) protocol, which can monitor the network status by collecting and reporting the status of the network at the data level. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] 1. When using INT, it is necessary to predict the traffic that may be carried on the data link in advance, so the same sampling rules need to be configured on the swit...

AI Technical Summary

Problems solved by technology

[0004] 1. When using INT, it is necessary to predict the traffic that may be carried on the data link in advance, so the same sampling rules need to be configured on the switch and service packets. For networks with complex topological structures, the operation is complicated and difficult;

[0005] 2. When the configured sampling rules match randomly, all traffic in the entire network will need to insert INT data, which greatly increases the pressure on the monitoring server
