Introduction: Requirements of the physical layer in a photonic switching network include a high channel bandwidth for the throughput of ultra-high bandwidth signals, fast switching speeds and optical processing of switching control algorithms to remove the speed bottleneck imposed by electronic processing. Integrated-optic waveguide switches offer a channel bandwidth comparable to that of the f...

In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...

Current data centers networks rely on electronic switching and point-to-point interconnects. When considering future data center requirements, these solutions will raise issues in terms of flexibility, scalability, performance and energy consumption. For this reason several optical switched interconnects, which make use of optical switches and wavelength division multiplexing (WDM), have been r...

A Unified Approach to Inter-Domain Routing Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited. Abstract This memo is an informational RFC which outlines one potential approach for inter-domain routing in future global internets. The focus is on scalability to very large networks and func...

In the frame of this work, we present an optical multicasting approach based on optical code-words. Our approach associates, in the edge node, an optical code-word to a group multicast address. In the core node, a set of tunable decoders are used to send a traffic data to multiple destinations based on the received code-word. The use of code-words, which correspond to the combination of an inpu...
