Data include non- continuous ones, like text and image, and continuous ones, like video and audio, which are characterized by time. A specification language to specify multimedia Quality of Service (QoS) parameters synchronisation mechanisms, it must be able to support the timing relationship between different types of data. Estelle, an internationally standardized Formal Description Technique (FDT) for specifying communication protocols and distributed systems, does not have enough expressing power to specify the time- dependent behaviours of a module of a distributed system. To address this limitation, we have developed an extended Estelle, called Time-Estelle (1) which is capable of describing QoS parameters and synchronization requirements of a DMS. In this paper, we first present a review of QoS formal specification, then Time-Estelle, a...

This property of the PON can be exploited for node consolidation where multiple central offices are replaced by a single one covering a larger service area. Such node consolidation is being particularly driven by the need for network operational cost saving, and is offering significant challenges to PONs. The degree of node consolidation that can be achieved is limited by the reach of conventional PON systems. In order to achieve a larger degree of node consolidation, an extension of the PON reach, beyond the conventional 20 km, is required. This article addresses the challenges of the dynamic bandwidth allocation (DBA), where increased reach results in a degradation of DBA performance and quality of service support. We use Real Time Probabilistic Systems to evaluate a typical PON syste...

Based on the QoS measures, we propose a Generalized Stochastic Petri Net (GSPN) based model, called QoS-GSPN, which can express the real-time behavior of QoS measurement for mobile networks. QoS-GSPN performance analysis methodology includes the formal expression and performance analysis environment.

Despite the recent findings of real time human behavior in measured traffic from data networks, much of the current understanding of IP traffic modeling is still based on simplistic probability distributed traffic. Unlike most existing studies that are primarily based on simplistic probabilistic model and traditional scheduling algorithms, this research presents an analytical performance model for real time human behavior queue systems with intelligent task management traffic input scheduled by a novel and promising scheduling mechanism for 4G-LTE system. Our proposed model is substantiated on human behavior queuing system that considers real time of traffic exhibiting homogeneous tasks characteristics. We analyze the model on the basis of newly proposed scheduling scheme for 4G-LTE system . We present closed form expressions of expected response times for real time traffic classes. We develop a discrete event simulator to understand the behavior of real time of arriving tasks traffic under this newly proposed scheduling mechanism for 4G-LTE system . The results indicate that our proposed scheduling algorithm provides preferential treatment to real-time applications such as voice and video but not to that extent that data applications are starving for bandwidth and outperforms all other scheduling schemes that are available in the market.

Modelling and analysing for multimedia applications in a mobile network, with real-time behaviour... more Modelling and analysing for multimedia applications in a mobile network, with real-time behaviour taken into consideration, is still a subject of much research. Generalized Stochastic Petri Net (GSPN) is well known formalisms used to represent and analyse communication and computer systems. However, it does not have enough expressive power to model timing behaviours of multimedia applications in a mobile network. To address this limitation, we develop quality of services based GSPN, which is capable of doing so. The extension offers the promise of providing real-time system predictability for systems characterised by substantial stochastic behaviour. With this model we model and analyse the handover and admission control schemes in the different multimedia traffic environments. Our result, thereby, provide the optimal performance achievable for these schemes under the real-time constraints in the given setting of design parameters.

We present a formal modelling language, called real-time stochastic process algebra (RT-SPA), to describe the real-time stochastic behaviour of optical communication systems. The language combines conventional stochastic process algebra with realtime semantics to describe complex systems in a compositional manner. It includes timed transition, parallel composition, probabilistic branching and hard real-time aspects. With this performance analysis methodology it is possible to obtain the design parameters of implementation using simulation with a lower computational time and cost than using conventional techniques. The adequacy of this framework applicability check is assessed by applying it to model and analyze wavelength-routed packet buffering techniques for optical networks.

This article presents MIMO-OFDM concept prototype of signal processing operations and simulate performance results. The prototype is based on the IEEE 802.11a/g standards at physical layer, supporting multiple antennas, adaptive modulation and coding, with peak rates up to 54 Mb/s. The proposed prototype architecture is modelled using VHDL-AMS-RTS, and synthesized using 0.35 mum CMOS standard cell library with a SYNOPSYStrade tool, as well as doing a timing simulation.

The major problem of existing performance methodology is the lack of feasibility in time-dependent and functional behaviours, as well as statistical traffic characteristics for distributed multimedia systems. The internationally standardised Formal Description Technique, Estelle, does not have enough expressive power to specify the time-dependent performance characteristics of a multimedia system. To address this limitation of Estelle, we have developed a variant of Estelle, called Time-Estelle. In this paper, we describe a method for analysing the performance of a multimedia protocol specified in Time-Estelle. To aid the analysis, we introduce a traffic model called the Time-interval Performance Indices in order to capture the burstiness and time correlations of realistic multimedia traffic. Thus, performance parameters of multimedia systems, such as the long-term average rate and short-term peak rate allocation, and exploitation of statistical resources utilisation, can be analysed. To demonstrate the soundness of our method, we have applied it to the Resource ReSerVation Protocol and some results are included in this paper.

We have developed Time-Estelle, an extended Estelle which is capable of doing so. Correct operations of this type of systems have stringent requirements for synchronisation of different entities or media data residing in a number of nodes possibly located very remotely from each other. Verification of formal specifications for such systems with time taken into consideration has been a subject of research. We have developed a method of verifying Time-Estelle specifications; it involves translating Time-Estelle specifications to Communicating Time Petri Nets which can then be verified by using the automated tool ORIS, with the dynamic behaviours of Estelle modules all supported. Using this verification method, this paper describes a timed verification of the Reliable Adaptive Multicast Protocol formally specified in Time-Estelle, and presents the results of the verification. Its contribution is that it represents a success in the use of a method in verifying a real-life protocol with timed properties specified formally.

An all-IP network architecture with reliable high-throughput air interface make orthogonal frequency division multiplexing access (OFDMA) based mobile worldwide interoperability for microwave access (mobile WiMAX) a viable technology for wireless multimedia services, such as voice over IP (VoIP), mobile TV, and so on. In this article, we first give an overview of the key aspects of WiMAX and describe multimedia broadcast multicast service (MBMS) architecture of the 3GPP. We propose a framework for combined real-time behaviors and stochastic process algebra. This is done with a modeling language, called real-time stochastic process algebra (RT-SPA), for describing the real-time stochastic behaviors of wireless networks. This methodology can then be analyzed using an automatic tool. With this performance analysis methodology it is possible to obtain the design parameters of implementation using simulation with a lower computational time and cost.

In these measurements, electron bunches with charge up to 20 pC were created by a 300 fs pulse duration Ti:sapphire laser system illuminating a polished copper cathode. Images of the electron beam were captured at two locations downstream from a solenoid focusing magnet. The focal spot size was studied as a function of bunch charge and accelerating gradient. Beam waists down to 85 microns were obtained. The focal spot size was found to be dominated by spherical aberration at low beam charges, however the beam trajectory is in good agreement with simulation.
