Abstract: A system and method for deploying a software build from a plurality of software builds is presented. A target computer sends a request for the software build to a build master. The build master authenticates the request, permitting only authorized requests. If the request is authorized, the build master identifies a build server that stores the requested software build. The build master generates request data that identifies the build server and authentication information, and returns the request data to the target computer. The target computer submits the request, with the request data, to the build server. The build server authenticates the request according to the request data. If the request is an authorized request, the build server returns the software build to the target computer.

Abstract: An improved apparatus and method for isolating faults in a complex communications network such as a collision-detection network. A wrap plug connected to a communications adapter of a computer system simulates multiple functions of the network environment, rather than a single, hardwired function. A method performs a comprehensive yet convenient diagnostic test of multiple functions of the adapter while a terminal is disconnected from the network.
