Optique: Towards OBDA Systems for Industry

Abstract: The recently started EU FP7-funded project Optique will develop an end-to-end OBDA system providing scalable end-user access to industrial Big Data stores. This paper presents an initial architectural specification for the Optique system along with the individual system components.

Choice as a principle in network architecture

Abstract: There has been a great interest in defining a new network architecture that can meet the needs of a future Internet. One of the main challenges in this context is how to realize the many different technical solutions that have developed in recent years in a single coherent architecture. In addition, it is necessary to consider how to ensure economic viability of architecture solutions. In this work, we discuss how to design a network architecture where choices at different layers of the protocol stack are explicitly exposed to users. This approach ensures that innovative technical solutions can be used and rewarded, which is essential to encourage wide deployment of this architecture.

A next generation architecture for air traffic management systems

Abstract: In an effort to increase the efficiency and safety of air travel while accommodating the growing demand for air traffic, the aviation community is working towards designing next generation air traffic management (ATM) systems. ATM will replace the completely centralized, ground based, air traffic control procedures. Within ATM, the concept of free flight allows each aircraft to plan four dimensional trajectories in real time, thus replacing the rigid and inefficient discrete airspace structure. These changes are feasible due to GPS and various other technological innovations. In this paper, we propose a decentralized ATM architecture, where much of the current ATC functionality is moved on board each aircraft. Within this framework, we present various issues that arise in the emerging area of hybrid systems based on our work in conflict resolution strategies between aircraft, and in flight mode switching logic.

System architecture for free-viewpoint video and 3D-TV

Abstract: This paper presents a system architecture of an acquisition, compression and rendering system for 3D- TV and free-viewpoint video applications. We show that the proposed system yields two distinct advantages. First, it achieves an efficient compression of 3D/multi-view video by extending a standard H.264 encoder such that near backward compatibility is retained. Second, the proposed system can efficiently compress both 3D-TV and free- viewpoint multi-view video datasets using the single proposed system architecture.

An atm switching system based on a distributed control architecture

Abstract: An ATM switching system architecture is presented which employs distributed control to cope with diversified requirements. ATM switching system is expected to efficiently and flexibly handle multimedia traffic, therefore traffic control architecture is one of the most crucial issues for ATM switching systems. The requirements, architectural concept and construction scheme of two important technologies, self-routing switches and quality control of statistical switching, are discussed. A switch fabric, which provides a unified inter-module inter face, switches and distributes cells between modules. It gives very stable switching performance under an arbitrary flow environment without centralized resource management. A three-layerd traffic control model is also presented which consists of cell transfer level, call control level and network control level. Control functions of each level and the interfaces among them are considered, then cell transfer level control schemes and their performances are discussed, including marking scheme for policing control and the effect of burstiness. Laboratory experiment system is designed and implemented to confirm the feasibility of the ATM switching system architecture concept. The system employs a VLSI memory switch with dynamic link speed control as an element of the self-routing switch fabric, achieving the capacity of 256 I55Mb/s lines. It also realizes efficient statistical switching functions such as policing control, multiplexing and quality control for multiple transport quality classes.
