Özet:

The trend of growing capacity of modern infrastructures and popularity of network services raises the requirements for multi-server information processing systems they work with. The occurrence of events on a regional and global scale affects the activity of processed data streams, which can lead to losses of processed information and decrease in the quality of services for end users. The dependence of the variation coefficient of time intervals between adjacent requests and the probability of loss of the request processed by the software module is found. The two-level control scheme of the shared memory resource of all modules and the functioning algorithm of managers are proposed. The experiment proves the efficiency of the developed method and algorithm for abnormal situations. This method is applicable and effective for various information processing systems and will allow the rational use of computing resources. The application of the method will allow preserving the efficiency of information processing systems for cases of local overload of nodes. Practical implementation of the method will reduce losses of processed information to 10 %. This is especially important for systems that process user-defined data streams based on the concept of software-defined networks.
