1. An alarm processing method for an optical transport network, comprising:
layering a service: according to characteristics of the optical transport network and attributes of the service, dividing the service into a first layer, a second layer, . . . , a (n−1)th layer, a nth layer from top to down, wherein the (n−1)th layer is a client layer, the nth layer is a service layer of the (n−1)th layer, and n is greater than or equal to 2;
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.
