The embodiment of the invention provides a hot plug fault recovery method and a distributed device and belongs to the technical field of data communication. The method comprises the steps of traversing at least one service board; judging whether preset times of fault recovery is carried out on the service board in which a loading fault has occurred or not when it is detected that in the traversing process, the service board in which the loading fault has occurred is in place; restarting the service board in which the loading fault has occurred for reloading if the preset times of fault recovery is carried out on the service board in which the loading fault has occurred; otherwise, forbidding the service board in which the loading fault has occurred. According to the method and the device, the recovery capability for a hot plug fault of the service board can be ensured, and the stability of the distributed device also can be ensured.
Description
technical field [0001] The invention relates to the technical field of data communication, in particular to a hot swap fault recovery method and distributed equipment. Background technique [0002] With the continuous development of network technology, people have higher and higher requirements on the reliability and flexibility of the network. It is necessary to use high-end distributed equipment network equipment at the core node to speed up the operation of the equipment and reduce the load pressure. When the distributed equipment is hot-swapping business boards (including line cards, switching cards, etc.), once the processing flow of a certain module is abnormal, it may cause the business board to be unable to continue loading or unloading, and even cause the main Faults such as the dead loop of related tasks on the control card, deadlock of semaphore or task suspension, etc., will eventually lead to the failure of the entire equipment system. [0003] In actual use, ...
