Abstract

A configuration change management system is provided. The configuration change management system includes a configuration information repository and a human-machine interface for interacting with field-installed communications network entities. Versions of communications network entity specific configuration information are stored in repository entries. Methods of managing configuration changes include: retrieving configuration information from communications network entities; storing thereof under version control in repository entries; comparing at least one retrieved repository entry from the repository; and configuration information retrieved from field-installed communication network entities; and submitting, for reconfiguration, of at least one field installed communication network entity, selected configuration information held in a corresponding repository entry. Advantages are derived from: a centralized tracking and storage of configuration information under version control, and the ability to compare versions of communications network entity configurations, reducing equipment downtime and reducing communications network management overheads. Further advantages are derived from an efficient method of debugging communications network entity configuration problems. The methods and system further enable easy migration of communications network entities to newer software/firmware releases, and fast provisioning of replacement communications network equipment.
