Updating software and configuration data in a distributed communications network

The author presents a method for the organization and controlled distribution of software and configuration data throughout a communications network. Central to the discussion are two concepts: download, which can be thought of as a mechanism by which network software and data are obtained and installed in a network component, and data reconciliation, which can be thought of as the process by which the consistency of all downloaded information within a network component is assured. A network component can use data reconciliation to determine what data is needed for operation and when that data has changed, thus requiring update. The download process can then be used to obtain the needed data. The methodology is illustrated by its implementation in an advanced, commercially available packet switching network.<>
