Distributed data acquisition and control systems in large-scale scientific experiments, like e.g. ITER, require time synchronization with nanosecond precision. A protocol commonly used for that purpose is the Precise Timing Protocol (PTP), also known as IEEE 1588 standard. It uses the standard Ethernet signalling and protocols and allows obtaining timing accuracy of the order of tens of nanoseconds...

The following article is about the network quality of service issues, which is a set of technologies that enable to users obtain from the network predicted level of services basing on particular rules e.g. throughput, delay and jitter. An investigation and comparison of QoS mechanisms, focusing on the Internet protocols has been done here, to analyze and compare existing solutions. Beginning from...
The downsizing of transistor dimensions enabled in the future nanotechnologies will inevitably increase the number of faults in the complex ULSI chips. To maintain the production yield at acceptable level, several levels of protection mechanisms will have to be implemented to tolerate the permanent and transient faults occurring in the physical layers. In this paper, we study fault tolerance at the...
Mobile phones market has become one of the most important industry in United Kingdom. In recent years mobile phones have gained more and more popularity and the number of their sales is still increasing. This success is caused by a few reasons. First of all, mobile phones enable people to communicate easily all over the world. Secondly, modern mobile phones provide additional features that make them...
This article makes an attempt to analyze the most essential aspects connected with IP based transmission in present and future mobile networks by means of network programming in J2ME. It presents simple programs, which are related with network programming in mobile phones. First program can communicate with server and collect some information. Second application allows the user of mobile phone to...
Today's world has been changing drastically over few past years in aspect of telecommunication technology development. World has become a small village, connected via large variety of media and devices. With grow of telecommunication industry popularity a need of Internet-mobile-fixed convergence has grown to be a significant issue to be considered and implemented. The matter is important as combining...
Modern enterprises often face the challenge of performing complex and time -consuming tasks that require more than one server machine to participate in. To address this issue wide Server Farms were deployed, that need constant monitoring and maintenance.
We present the proposal of functional extensions to email clients (and alternatively also transmission protocols). Changes shown are supposed to help people working with email programs in different places, trying to get the same emails at home, work and other locations. We also propose methods for reducing the number of emails sent without the intended attachments.
