A method of operating a distributed processing, interactive computer network is described. The network is designed to provide very large numbers of simultaneous users access to large numbers of applications which feature interactive text/graphic sessions. The network includes one or more servers, interactive applications, and one or more reception systems, the reception systems being capable of communicating with the respective servers and receiving applications from them. In this arrangement, application are structured from packets termed &ldquo;objects&rdquo;, the objects including the display data and/or program code required to support execution of the application. When a request for an application is received at a reception system, if any objects for the application are unavailable from the reception system, the objects are requested from the server and supplied to the reception systems requesting the application objects. In accordance with the method, the respective reception systems include display interfaces for presenting applications to respective users the respective display interfaces featuring a plurality of display partitions. Also in accordance with the method, at least some of the respective applications are divided into sections, the respective sections being designed to form at least a part of an application display page. Further, application sections are constructed from objects such that display page parts of one or more respective applications may be controllably presented at the partitions of the interface to permit at least application page part nesting, scrolling and navigation, the objects being of multiple types and including display data and/or program code for enabling execution of applications and their presentation at the interface partitions of the respective user reception systems.

Interactive computer network and method of operation

A method is described for operating a distributed processing, interactive computer network. The network is intended to provide very large numbers of simultaneous users access to large numbers of applications which include pre-created, interactive text/graphic sessions. The network includes one or more servers, interactive applications, and one or more user reception systems. The respective reception systems are designed to and are capable of communicating with the respective servers and receiving applications from them. The respective reception systems feature a display interface, as well as reception system software, operating system software and CPU for executing the applications and presenting applications to respective users. The method features steps for preparing the applications in a high-level programing language so that the applications may be executed at the respective reception systems independently of the reception system CPU type and operating system type by interpreting the respective applications at runtime with an interpreter available at the respective reception systems. In accordance with the method, the applications are divided into sections and structured with objects of multiple types containing application display data and/or program code. The objects are distributed in the network and provided at run time at a reception system at which the respective applications are requested. The method further features steps for providing the respective application programs with a structure that features a header section, data structure section and code section implemented in objects. In this arrangement, method steps are provides to enable respective application programs code section to include one or more procedures for supporting system services, the procedures including a key word for identifying the respective procedures. Additionally, the method includes steps for enabling application program data structure section to identifying the data structure for the respective application programs. Further, the method includes steps for enabling the respective application program structure to include a header section that identifies the respective application program names.

A distributed processing, interactive computer network and method of operation is described. The network is designed to provide very large numbers of simultaneous users access to large numbers of applications which feature interactive text/graphic sessions. The network includes one or more host computers having application data stores; a plurality of concentrator computers, also including application data stores, the concentrator computers being connected in groups of one of more to each of the host computers; and a plurality of reception system computers connected in groups of one or more to each of the concentrator computers, the reception system computers being arranged so that respective users can request interactive applications at the reception system computers. In accordance with the design, the reception system computers also include application data stores. The method for operating the network includes steps for generating the interactive text/graphic sessions from objects that include data and/or program instructions. Additionally, the method features steps for distributing objects among the data stores of the network computers, and, thereafter, permitting the reception system computer at which an application is requested to selectively collect objects required for the application from the network and the respective reception system so that the requested application may be presented at the reception system based on the objects collected. This operation decreases processing demand on the higher-level network elements, permitting them to function primarily as data supply and maintenance resources, thereby reducing network complexity, cost and response time.
