Abstract

A method and device for preventing a failure processing delay are provided in the disclosure. In an example, when the number of queue elements in an equivalence class time-window queue reaches a set threshold (denoted as N) in a set time-window, it means that there are N Bidirectional Forwarding Detection (BFD) sessions in the same equivalence class set, that detect Down events. It thus can be intelligently inferred that a public network path carrying the N BFD sessions breaks down. For processing a failure in time and reducing data stream loss on an upper layer, the present disclosure may allow reporting a corresponding Down event for each BFD session in the equivalence class set to which the N BFD sessions belong.
