Method for detecting time delay of optical transport network based on pseudo-random code and storage medium

The invention discloses a method for detecting time delay of an optical transport network based on a pseudo-random code and a storage medium. The method comprises the following steps that: equipment accesses the optical transport network; a service supported by the optical transport network is configured on the device; starting a pseudo-random code detection function on the equipment; stopping pseudo-random code detection to check the connectivity of the service; restarting pseudo-random code detection; stamping a timestamp on the pseudo-random code data; and obtaining the time delay of the optical transport network according to a pseudo-random code result. According to the method, the connectivity, the network service quality and the storage medium of the OTN network can be known more conveniently and quickly through the functions of the equipment in a simple and crude test environment or an environment without a tester. 本发明公开了一种基于伪随机码检测光传送网络时延的方法及存储介质，包括以下步骤：设备接入光传送网络；设备上配置光传送网络支持的业务；设备上开启伪随机码检测功能；停止伪随机码检测查
