  • OPTICAL TRANSPORT NETWORK ALARM PROCESSING METHOD AND APPARATUS, AND NETWORK MANAGEMENT SYSTEM AND MEDIUM
    Publication number: 20230047670
    Abstract: Provided are an alarm processing method and apparatus for an optical transport network, a network management system and a non-transitory computer readable storage medium. The alarm processing method for an optical transport network may include: acquiring intra-layer alarms of respective layers of a service layer by layer; acquiring a root alarm of an associated layer corresponding to a current layer based on the intra-layer alarms; and determining a service fault point based on the root alarm.

  • Method for measuring transmission delay of optical transport network device and source OTN device
    Patent number: 10361938
    Abstract: A method for measuring transmission delay of an optical transport network (OTN) device and a source OTN device. The method comprises: a source OTN device receives a delay measurement request transmitted by a user, generates a delay request frame, and transmits the delay request frame to a destination OTN device; the source OTN device receives a response frame returned from the destination OTN device, the response frame including a first time information; after receiving the response frame returned from the destination OTN device, the source OTN device obtains the system time T4 at when the response frame is received by the source OTN device; the source OTN device parses the response frame to obtain the first time information, and calculates the transmission delay between the source OTN device and the destination OTN device according to T4 and the first time information.
