Abstract

Techniques are provided for using library caches in a distributed software development environment that includes a plurality of development sites. Each of the plurality of development sites is associated with at least one library cache area that is accessible over a LAN to a set of network nodes included in that development site. A configuration management server is operable to cause all of a plurality of files associated with a software project to be transferred, in an optimized package, from a file server to a particular development site that is communicatively connected to the file server over a WAN. The configuration management server is also operable to cause the plurality of files to be stored in a particular library cache area that is associated with the particular development site, and to cause one or more of the plurality of files to be transferred from the particular library cache area to a work area that is configured on a developer network node in the particular development site.
