Ensuring the quality of service flows in multiservice infrastructure based on network node virtualization

The model of the virtual router with static and dynamic reconfiguration of resources is developed. This model allows to create effective virtual device with optimal parameters (length of queue, management discipline for queue overflowing, the number of service devices and their modes) in order to provide the required level of QoS for all services. The use of virtual network devices in the existing network infrastructure will help effectively allocate the available network hardware resources under a huge load arriving in the network with a variety of types of flows. The use of the developed model will also ensure the necessary quality of experience for the end users for the relevant services, including streaming media as the most spread and resource demanding type of traffic.
