Abstract
Embodiments of the present disclosure disclose a method and an apparatus for protecting a subscriber access network, and relate to the field of communications. The method includes: connecting a Broadband Network Gateway BNG device and N predetermined Digital Subscriber Line Access Multiplexers DSLAMs to an aggregation device AGG; allocating an active BNG interface for each of the N DSLAMs, allocating a standby BNG interface set for the N DSLAMs to obtain a backup relationship, and sending the backup relationship to the AGG (102); and backing up subscriber data on the DSLAMs to the standby BNG interface set, so that when an active BNG interface fails, the AGG switches subscribers on a DSLAM served by the failed active BNG interface to a standby BNG interface in the standby BNG interface set.
