Human perception-based distributed architecture for scalable video conferencing services: theoretical models and performance

This research work proposes a human perception-based distributed architecture for the multiparty video conferencing services. The new architecture can effectively reduce the unnecessary traffic of the multilayer video streams on the overlay network. Rich theoretical models of the three different architectures: the proposed perception-based distributed architecture, the conventional centralized architecture, and perception-based centralized architecture have been constructed by using queuing theory to reflect the traffic generated, transmitted, and processed by the three architectures. The performance has been considered in different aspects from the total waiting time to the required service rates. Together, the modeling tools, the analysis, and the numerical results help to answer the common concern about advantages and disadvantages of the centralized and distributed architectures. Overall, the proposed human perception-based distributed architecture can maintain a smaller total waiting time with a much smaller requirement of service rate in comparison with the conventional centralized architecture and perception-based centralized architecture.

A positively self-feedbacked Hopfield neural network architecture for crossbar switching

We propose a positively self-feedbacked Hopfield neural network architecture for efficiently solving crossbar switch problem. A binary Hopfield neural network architecture with additional positive self-feedbacks and its collective computational properties are studied. It is proved theoretically and confirmed by simulating the randomly generated Hopfield neural network with positive self-feedbacks that the emergent collective properties of the original Hopfield neural network also are present in this network architecture. The network architecture is applied to crossbar switching and results of computer simulations are presented and used to illustrate the computation power of the network architecture. The simulation results show that the Hopfield neural network architecture with positive self-feedbacks is much better than the previous works including the original Hopfield neural network architecture, Troudet's architecture and maximum neural network for crossbar switching in terms of both the computation time and the solution quality.

A Flexible UMTS-WiMax Turbo Decoder Architecture

This work proposes a VLSI decoding architecture for concatenated convolutional codes. The novelty of this architecture is twofold: 1) the possibility to switch on-the-fly from the universal mobile telecommunication system turbo decoder to the WiMax duo-binary turbo decoder with a limited resources overhead compared to a single-mode WiMax architecture; and 2) the design of a parallel, collision free WiMax decoder architecture. Compared to two single-mode solutions, the proposed architecture achieves a complexity reduction of 17.1% and 27.3% in terms of logic and memory, respectively. The proposed, flexible architecture has been characterized in terms of performance and complexity on a 0.13-mum standard cell technology, and sustains a maximum throughput of more than 70 Mb/s.     

A flexible parallel architecture for relaxation labeling algorithms

The design of a flexible parallel architecture for both the discrete relaxation labeling (DRL) algorithm and the probabilistic relaxation labeling (PRL) algorithm is addressed. Through the analysis of parallelism in the computational models of both algorithms, the parallel execution of the algorithms on a flexible parallel architecture is presented. Three basic types of parallel operations are performed in the architecture: simultaneous, pipeline, and systolic. An illustrative example is used to show how the DRL algorithm can be executed on the parallel architecture. In doing so, the processing element (PE) organization and the combiner organization of the architecture are described. The same architecture with programmable functional units is shown to be able to execute the PRL algorithm, too. The performance comparisons between the proposed architecture and some other existing ones are also given

Security-State Adjustable Gateway with Threat-Based Configuration

This paper proposes a configurable secure gateway architecture which allows the system administrators to dynamically configure the security mechanisms upon deployment or during the run-time. Rather than allowing the system administrators to turn on or off individual security mechanisms, the proposed architecture allows the administrators to configure the gateway based on the security threats to be overcome. The current common architecture leads to tremendous administration overhead and increases the chance of misconfiguration vulnerability. We propose a novel software architecture to aid the product designers to avoid the misconfiguration vulnerability and the end-users to ease the administration overhead. The software architecture makes use of the threats to the gateways and the occurrence relation between the threats to configure the security software components on the gateways. With the software architecture, the end-users can focus on determining the desired security features rather than the software configuration. Moreover, the architecture allows the product designers or security service to incrementally revise the software configuration when new threats appear.
