Clustered computing systems, using commercially available computers networked in a loosely-coupled fashion, can provide high levels of reliability if appropriate levels of error detection and recovery software are implemented in the middleware and application layers. In this paper we present a modeling approach for analyzing the hardware and software reliability of clustered computing systems. ...

Since there is an increasing demand for fast networks and switches, the electronic data processing imposes a severe bottleneck and all-optical processing techniques will be required in the future. All-optical flip-flops are one of the key components because they can act as temporary memory elements. Several designs have already been demonstrated but they are often relatively slow or complex to ...

The causes for feature interactions are many, therefore several remedies will have to be applied together. In this paper, we investigate the architecture of the users' interface of a telephone switching system and tackle a certain kind of feature interactions by employing a more modular structure for the design of the system and its features. We propose to apply results from the research on hum...

We report the development of two liquid waveguide based photonic elements for use in reconfigurable photonic systems. This work demonstrates the ability to couple light from a conventional optical fiber to an adaptable liquid-core/liquid-cladding waveguide and back again to an optical fiber(s) enabling us to take advantage of both liquid- and solid-state photonic modalities. We demonstrate and ...

We propose this wireless system to send information to people with disabilities (especially deaf people).The most effective...

Toady’s telecommunication network serves as an essential platform in our society for exchange of information in its various possible forms, viz., voice, data and video, and thus helps us in living the life of this modern era. Networking practices have evolved almost over two centuries with an unbelievable range of technologies, services and standards, calling for accommodation of heterogeneous ...

label switching technology is a flexible and high performance method for forwarding layer three packets that are mapped to layer two flows. each label switch router, lsr, needs a specific label for every flow, where the number of labels depends on the mapping and granularity of flows. data and control driven methods are the most significant and popular methods in label mapping policy. the above...

A number of research works have been devoted to the optimization of protection strategies (e.g. transmission line switch off) of critical infrastructures (e.g. power grids, telecommunication networks, computer networks, etc) to avoid cascading failures. This work aims at improving a previous optimization approach proposed by some of the authors [1], based on the modified binary differential evo...
