Abstract: A network system includes a reconfigurable network and a network management system. The network management system can represent the network in the form of a network image. Network image objects, corresponding to network objects, can be selected as copy sources and paste targets. A copy-and-paste operation modifies the network image to indicate a potential modification of the actual network in which the configuration of the network object corresponding to the selected copy source object is applied to the network object corresponding to the selected image object. In addition, the copy-and-paste operation can automatically represent a common connection of a source object input and a target object input to a common data source. Furthermore, the copy-and-paste operation can automatically connect outputs of source and target objects to a comparison function so that the implementation of the copy-and-paste operation on the actual network can be validated.

Abstract: A document reader program determines the existence of an updated version of a document file at a network location specified by an original version of the document file. The document reader program then presents the user a choice of rendering the original version or the updated version in human-cognizable form. For example, a user can request help for a host application, which accesses an original version of a help file via the document reader. Instead of displaying information from the original help file, the reader access a network location specified in the original help file, downloads an updated help file and then displays its information to the user. The updated help file can correspond to the local version of the host application or, in another embodiment, the most-recent help file for the most-recent version of the host application.

Abstract: A software application includes a document generator. A user can download from an upgrade website documentation (e.g., release notes) describing the differences in operation between a post-upgrade version of the application that would result if a target upgrade is implemented and a pre-upgrade version of the application, e.g., the one available on the user computer system. The document generator can generate full documentation for the post-upgrade version from the pre-upgrade documentation and the upgrade documentation. The post-upgrade documentation has a revision display mode and a non-revision display mode, the former showing the changes from the operation of the pre-upgrade version to the operation of the post-upgrade version.
