  • Patent number: 6874021
    Abstract: A page for sending to a client process from a server during network management incorporates a form having a plurality of input fields and a submit button. The form is associated with either a first submit method or a second submit method. The first submit method is for obtaining information about a state of a particular network device. The second submit method is for changing the state of a particular network device. The page is sent to the client process. In response to activation of the submit button in the client process, routines are executed to operate on the particular network device based on which submit method was associated with the form. Using these techniques, a single set of input fields can be designed for both displaying and editing the state of network devices.

    Abstract: Techniques for developing device-centric network management applications include a template. A computer platform includes one or more processors and an operating system. The template includes one or more sequences of statements of a platform-dependent scripting language. The statements are processed by a Web server executing on the platform. The statements cause the Web server to define a plurality of standard management methods and call at least a first standard management method. The statements also cause the Web server to define page level variables for holding in memory values used as parameters for the standard management methods. The template also includes a place to insert application-specific statements for presenting network information to a Web-based client process and for receiving input from the Web-based client process. A developer inserts the application-specific statements.
