A kind of processing method and device for OLt uplink CRC error

Abstract

An embodiment of the present invention provides a method and device for processing CRC errors in an OLT uplink link. The method includes: collecting monitoring data, obtaining information about OLT uplink ports with CRC errors based on the monitoring data, and updating the uplink port information based on the growth rate of the CRC. Classify the port information to obtain the classified information table; perform data calculation on the classified information table to obtain the peak traffic information and peak traffic generation time of each link uplinked by the OLT; decide the emergency repair behavior according to the peak traffic information, and the emergency repair behavior includes link-level automatic Switchover and equipment-level automatic cutover; determine the emergency repair time according to the peak traffic generation time, obtain the processing time limit according to the emergency repair time and synchronize it to the alarm work order. The method and device for processing the CRC error of the OLT uplink provided by the embodiments of the present invention, when a CRC error occurs at the OLT uplink port, there is no need to judge the failure business behavior, and there is no need to manually complete link switching or service cutover. The quick evaluation of the service carrying capacity and the decision-making of the preemption behavior can be realized.

Description

technical field [0001] The present invention relates to the technical field of data communication networks, in particular to a processing method and device for OLT uplink CRC errors. Background technique [0002] Cyclic Redundancy Check (hereinafter referred to as CRC) is a method of providing error checking during data transmission, which mainly ensures that the receiver completes the reception after confirming the correctness of the data before receiving the data. [0003] With the rapid development of the Internet TV business of operators, the pressure of network maintenance and guarantee continues to rise. Since the TV business is more sensitive than the broadband Internet business, especially to CRC errors, the complaints of artifacts caused by CRC errors have increased from time to time. [0004] At present, in order to deal with customer complaints about blurred screen faults, the business department usually conducts an end-point test first, and then notifies the uppe...

Problems solved by technology

[0005] The existing solution does not form an intelligent analysis and processing mechanism for the CRC error of the OLT uplink port that is sensitive to TV services. Usually, after the customer complains, it is necessary to manually check whether there is a CRC error in the OLT uplink port. If there is, it needs to be operated and maintained. It is inefficient for personnel to manually complete link switchover or service cutover at the first time, and there is no fast and accurate evaluation method for the service carrying capacity of other links, which may lead to excessive traffic after link switchover. Link congestion causes service quality complaints. At the same time, after the service is restored, the automatic service cutback operation cannot be triggered immediately. With the rapid development of the TV service, and due to the sensitive nature of the TV service, the above problems need to be solved urgently
