Remote Access to 3D Models for Research, Engineering, and Art
Found in: IEEE MultiMedia
By Sven Ubik,Zdeněk Trávníček,Petr Žejdl,Jiří Halák
Issue Date:October 2012
pp. 12-19
Stereoscopic (3D) models and visualizations can add value to current videoconferencing systems by offering a higher level of immersion when accessing remote 3D models. The low-latency remote access to 3D models in high resolution over high-speed networks c...
Evaluating Application-Layer Classification Using a Machine Learning Technique over Different High Speed Networks
Found in: Systems and Networks Communication, International Conference on
By Sven Ubik, Petr Žejdl
Issue Date:August 2010
pp. 387-391
Application–layer classification is needed in many monitoring applications. Classification based on machine learning offers an alternative method to methods based on port or payload based techniques. It is based on statistical features computed from networ...
Data Stream Processing for 40 Gb/s Networks
Found in: Digital Telecommunications, International Conference on
By Jirí Halák, Sven Ubik, Petr Žejdl
Issue Date:June 2010
pp. 149-152
For emerging 40 Gb/s computer networks, we need devices that are capable of sustained line-rate operation for monitoring, test patterns generation and data stream processing. In this paper, we describe design options and our practical experience with devel...
Receiver synchronization in video streaming with short latency over asynchronous networks
Found in: Design and Diagnostics of Electronic Circuits and Systems
By Jiri Halak, Sven Ubik, Petr Zejdl
Issue Date:April 2010
pp. 403-405
Video transfers are an expected driver application area of the future Internet. When sending real-time video signals over an asynchronous network, such as Ethernet, some mechanisms need to be used to adjust the rendering speed on the receiver to the data s...
MTPP - Modular Traffic Processing Platform
Found in: Design and Diagnostics of Electronic Circuits and Systems
By Jiri Halak, Sven Ubik
Issue Date:April 2009
pp. 170-173
High-speed (10 Gb/s and above) network monitoring and traffic processing requires hardware acceleration. Different applications require different functions to be placed in hardware. Current packet capture cards include fixed firmware, which is difficult to...
Real-time anonymization in passive network monitoring
Found in: Networking and Services, International conference on
By Sven Ubik, Petr Zejdl, Jiri Halak
Issue Date:June 2007
pp. 100
<p>Passive network monitoring that observes user traffic has many advantages over active monitoring that uses test packets. It can provide characteristics of real user traffic, that cannot be detected actively.</p> <p>However, when proces...
ABW--Short-Timescale Passive Bandwidth Monitoring
Found in: International Conference on Networking
By Sven Ubik, Demetres Antoniades, Arne Oslebo
Issue Date:April 2007
pp. 49
Bandwidth usage monitoring is important for network troubleshooting and planning. Traditionally, used bandwidth is computed from router interface byte counters read by SNMP. This method only allows to check long-term averages of the total used bandwidth wi...
