The method of dynamic prioritization of real-time multimedia flows is proposed. This method stabilizes the delay of packet processing when transmitting real-time flows in cases of network devices overload. As the result, the jitter of the flow can be significantly decreased. Moreover, decreasing the delay of packets processing allows to use the preserved time for more intelligent encryption algorithms that are usually very time-consuming. Based on the proposed prioritization method the algorithm of processing of high priority real-time flows that suffer from high delay has been developed in this paper. The algorithm is able to establish how long the specific packet has been transmitting through the network and determine the way to process it as fast as possible if the packets delay has exceeded a critical value. The proposed method and algorithm form a basis for ensuring quality of service in transport networks of long-distance class that require high level scalability and quality of service. This features are especially important when organizing networks of civil and military purposes including wireless broadband access networks. The proposed method becomes especially effective under the conditions of high incoming load on the communication core of the network since even small reduction of real time packets delay significantly increases quality of service. In case of special purpose networks, the developed algorithm allows to stabilize the delay and significantly decrease jitter which are a crucial factor when ensuring promptness of network reaction on the crisis situation [ABSTRACT FROM AUTHOR] |
