    Duplication of Key Frames of Video Streams in Wireless Networks

    In this paper technological solutions for improving the quality of video transfer along wireless networks are investigated. Tools have been developed to allow packets to be duplicated with key frames data. In the paper, the authors tested video streams with duplication of all frames, with duplication of key frames, and...

    Packet-Pair Technique for Available Bandwidth Estimation in IPv6 Network

    This paper presents experimental checking of the model for measuring available bandwidth in IPv6. The experiment was performed using a measuring infrastructure RIPE test box, ensuring precision accuracy. The experimental results showed that to increase the accuracy of available bandwidth, the authors need to neutralize the effect of the variable...

    Active Flows in Diagnostic of Troubleshooting on Backbone Links

    This paper aims to identify the operational region of a link in terms of its utilization and alert operators at the point where the link becomes overloaded and requires a capacity upgrade. The number of active flows is considered the real network state and is proposed to use a proxy...

    What Type of Distribution for Packet Delay in a Global Network Should Be Used in the Control Theory?

    In this paper correspondence between experimental data for packet delay and two theoretical types of distribution is investigated. Calculations have shown that the exponential distribution describes the data on network delay better, than truncated normal distribution. Precision experimental data to within microseconds are gathered by means of the RIPE Test...

    Throughput Metrics and Packet Delay in TCP/IP Networks

    Measurement of throughput metrics like available bandwidth and capacity gives a great chance to predict the end-to-end performance of applications, for dynamic path selection and traffic engineering, and select among numbers of differentiated classes of service. The throughput metric is an important metric for several applications, such as grid, video...
