Subject aims expressed by acquired skills and competences
The aim of the subject is to provide an overview of modern technologies of intelligent control of network infrastructures, their applications and practical configuration. Students will understand modern methods of secure interconnection of enterprise networks and data centres over transport networks, technologies of load distribution in server farms and methods of network infrastructure management. Students will also learn to choose and configure network devices for secure interconnection of the remote sites over the shared transport network infrastructure. Development of applications embedded into network infrastructure and their integration with external systems will be also discussed.

Summary
The subject provides an overview of modern technologies of intelligent control of computer network infrastructures, especially enterprise networks and data center networks, including methods for their secure high-speed interconnection. Mechanisms of interfacing with transport networks and optimization of transferred flows are also discussed. Further,. methods of modern methods of network management are explained. The final part presents possibilities of development of applications embedded into networking devices and their integration with external systems.
