Updating method for service parameters of network element cluster

The invention discloses an updating method for service parameters of a network element cluster. The updating method comprises the following steps: forming the network element cluster through a main network element and a plurality of auxiliary network elements; obtaining a new configuration file through monitoring changes of a configuration file, stored in the main network element, in the network element cluster; reading configuration information in the new configuration file; updating the service parameters of the auxiliary network elements in the network element cluster according to the configuration information; configuring self service parameters by the auxiliary network elements according to the configuration file of the main network element, wherein the configuration file does not need to be stored in each auxiliary network element; when application service provided by the network element cluster is changed, only modifying the configuration file stored in the main network element, so as to configure the
