A method for providing time-critical services via a flow control environment, wherein each service is assigned a server component that includes at least one application instance and that is formed by a flow control component that is loadable into the flow control environment and executed there, where an individual virtual communication network is made available for each server component via the flow control environment, a reverse proxy of a subnetwork, comprising the flow control environment, forwards service access requests, for use of the services outside of the subnetwork in accordance with predefined forwarding rules, to the respective server component via its virtual communication network, and the where the virtual communication networks are used for all application instances of the respective server component for forwarding the service access requests.

Method and system for providing time-critical services via a flow control environment

A method for processing data in a data processing system () which includes a number of data processing units (), and operator and observation units (), which are interconnected by way of a data transmission unit (), whereby a respective data processing program () with corresponding function modules (FBto FBn) and data modules (DBto DBn) is implemented in the data processing units (). At least one identifier (K, KE, KI) for the function modules and data modules is stored in a respective conversion table () belonging to each data processing unit (). When an external data processing unit () accesses a data module (DBto DBn) and/or a function module (FBto FBn) of another data processing unit (), a conversion table () mediates by using an external identifier (KE) that characterizes the access and verifies whether a matching internal identifier (KI) is stored for the particular external identifier (KE).

Method for processing data using external and internal identifiers to provide reliable access to the data even when reconfigurations of the data occur, and associated system
