Abstract
The invention relates to a method and means of workload balancing for a multitude of applications servers. The method comprises a first-step, wherein an application client sends an application request to a request queue of a dispatcher. In a second step the dispatcher is extracting an application request from said request queue. Within the second step the dispatcher selects a certain one of the application servers to which the extracted application request is to be sent to based on a table. The table is administered by the dispatcher and the table comprises an indication of the workload of the application servers. Also within the second step the dispatcher administers the table according to the selection and the dispatcher sends the extracted application request to said certain application server. The method comprises a third step, wherein an application server after processing an application request returns to the dispatcher a response comprising an indication of its current workload. In a fourth step the dispatcher is administering the table according to said response.
