This paper reports on a graph-based approach to enable real-time update of 3D shared elements over the network between multiple artists working simultaneously on the same 3D scene. It presents an experimental framework for exploring real-time collaboration in Digital Content Creation such as animation. The framework combines a push- pull network architecture and data translation protocol with hybrid command/data replication mechanisms. This enables the synchronization of object components and hierarchy between multiple instances of the same Digital Content Creation application in a non-destructive way. Conflicts between users are prevented with a strong right management system. We demonstrate the interest of such an approach by means of an application example in Blender and discuss collaborative experimental sessions outcomes over a Local Area Network and through the Internet.

In order to meet the real-time demands of some equipment networked test, the time synchronization techniques of ATS based traditional instrument buses are compared with the techniques of LXI ATS. Accordingly，the necessity of LXI ATS time synchronization technique study is put forward. The sorts of time synchronization techniques based on Local Area Network are analyzed. In addition, some methods which could improve the level of LXI data real-time communications are presented. Afterwards, technique realizations of PTP are studied in detail. Local Area Network techniques and IEEE 1588 Precise Time Protocol are adopted in the LXI Automatic Test System which designed in the paper, and the level of time synchronization precision in the system is improved.

Research Platform

During last few years avionics system research platform was invented at the Military University of Technology. This modular simulator allows user to design and verify avionics system software using hardware-in-the-loop technique. Mathematical model of an airplane under tests is implemented on a high-performance computer which response to all control signals and environmental disturbances. Environment is simulated on a separate computer which can also visualize orientation and movement of the airplane. Plane structure and aerodynamic features as well as control data can be modified accordingly to user needs. The third PC is used as an interface unit between research platform and main computational unit of the avionics system. This device can send and receive information in real-time using various data protocols and interfaces depending on sensors and actuators that are planned to be used in real system. Those three computers work in a local area network and exchange data using Gigabit Ethernet standard. Possibility to simulate behavior of an UAV controlled by the developed avionics system implemented on an embedded computer working in hardware-in-the-loop mode on the platform, allows software developer to debug any part of the application in various environment conditions very close to reality. Research platform gives also the possibility to modify algorithm and adjust its parameters in real-time to verify suitability of the implemented avionics system software for the particular UAV. The avionics system software developed using this simulation method minimize expensive in-flight tests and assure failsafe performance after first successful flight

In order to be competitive enterprises continuously implement ICT strategies & architectures to improve manufacture, research, products quality, sales, services and costs control. All large enterprises have a local area network, a virtual private network, an Intranet and Internet, servers and workstations for operations, administration and management working together for the same objective: profits. The virtual enterprise and the virtual team?s concepts are discussed in this article. This work analyzes the network architecture for geographically dispersed enterprises (seen as virtual enterprises) as support for virtual project development by virtual teams work. In addition, the paper presents an enterprise networks monitoring solution using open source software (OSS).
