LOCAL AND METROPOLITAN AREA NETWORKS

Abstract
The test and performance evaluation of high speed networks pose problems that cannot be solved by traditional equipment. In this paper, the concept of a powerful and versatile tool, capable of generating and detecting traffic to test and assess the performance of such networks, is presented.

VIDEO COMMUNICATIONS AND PACS FOR MEDICAL APPLICATIONS

Abstract
This contribution describes a Videotex terminal with photographic capabilities based on a personal computer (PC). This system takes advantage of a recently available support - the Integrated Services Digital Network (ISDN) - which represents a significant improvement in the performance of communication systems, and is intended to offer a new and practical service while maintaining compatibility with the Alphamosaic Videotex.

LECTURE NOTES IN COMPUTER SCIENCE

Abstract
The provision of real time services through a Packet Switched Network, requires the adoption of end-to-end synchronization methods. Several of these methods, are compared and a specific hardware solution is discussed. Results obtained through a specially designed Simulation Programme are included, for several network time delay jitter distributions and synchronization methods. These results are used to evaluate systems and design parameters.
