Grey fault diagnosis method applied to telecom bearing network

Abstract

The invention discloses a grey fault diagnosis method applied to a telecom bearing network. The grey fault diagnosis method comprises the following steps: step 1, acquiring information of all paths inthe whole telecom bearing network; step 2, sending UDP detection packets on all the paths to measure the packet loss conditions of the paths; and step 3, for each interface, link and equipment in allthe paths, respectively analyzing the packet loss condition of all the paths passing through the interfaces, links and equipment, and diagnosing the gray fault occurrence position in the telecom bearing network according to the packet loss condition. The method does not need any hardware update, can be quickly deployed in a telecom bearing network environment, and can quickly find and position gray faults in the network.

Description

technical field

[0001] The invention relates to network fault diagnosis, which is a gray fault diagnosis method applied to telecommunication bearer network. Background technique

[0002] The telecommunications bearer network contains tens of thousands of servers, and all business data must be transmitted to users through the telecommunications bearer network. Therefore, network failures are not accidental but a normal occurrence. These network failures can be caused by, for example, routing configuration failures, loose links, network equipment hardware failures, and network equipment software defects. Among them, gray failures are very common and are the main cause of abnormal service availability and performance. Gray faults manifest in subtle ways, such as random packet loss (packet loss with a certain probability), performance degradation, flaky I / O, memory thrashing, and non-fatal exceptions. Different from fail-stop failure, packet loss is random when a gray fault oc...
