Configuration Management with the NSE

The Sun Network Software Environment (NSE) is designed to support both developers and release engineers who are working on large software projects. It is a network-based object manager designed to support closely cooperative, parallel development work by moderate sized work groups and provide configuration management for larger efforts. It supports parallel development through an optimistic concurrency control mechanism, in which developers do not lock objects they wish to modify but instead copy objects, modify the copies, and merge the modified objects with the originals. More detailed descriptions are found in [Cour89] and [AHM89]. The sections below describe several aspects of the NSE design and serve to illustrate its key design principals.
