It has been found that architecture shown in Figure 1, performs better in comparison to other loop buffer based architectures [2][3] [5][6] [7] [8] . In these architectures, main optical power signal loss is due to the splitter/co mbiner, which is used to realize the switch arch itecture.…”

“…High priority packet loss probability at load 0.6 is below 6 10 ,  which is almost negligible. At traffic load of 0.7, high priority packet loss probability is approximately 5 10  and low priority packet loss probability is nearly 3 10  . It can be inferred that the switch can provides better quality of service to high priority packets than low priority packets.…”

Abstract-In this paper, an all-optical regenerator based, photonic packet switch arch itecture, wh ich consists of the fiber loop for the storage of the contending packets, is considered. In the loop buffer, the available buffer space may not be fully utilized due to the limited re-circulat ion count of the data placed on buffer. This limit can be counteracted by placing a poo l of regenerators inside the buffer. As optical regenerators are costly devices, hence they should be placed optimally in the buffer. The simu lations results are presented by consider Priorit ized and nonprioritized traffic. It is shown in the results that regeneration of data is essential if prioritized traffic has to be considered.

“…All of them have their advantages and disadvantages. The first loop buffer based architecture was proposed by Bendelli (1995). This architecture requires a very large number of components for buffering; semiconductor optical amplifier (SOA), and also the size of the demux and mux effectively scales linearly with required number of buffer wavelengths.…”

This paper presents optical packet switch architecture with large buffering capacity for the contention resolution of the packets. The main feature of the architecture is no requirement of Demux/Mux and splitter/combiner which are used in most of the other loop buffer based switch architectures. Therefore physical loss of the architecture is very less, and switch performance is not limited by the physical degradation of the signal. In the buffer, TWCs/SOAs are replaced by Tunable Fiber Bragg Gratings (TFBGs). The use of TFBGs inside the buffer is a novel approach towards buffering structure. The architecture presented here can be modeled as output queue buffer scheme. This paper investigates the advantages of the proposed architecture over the earlier architecture. The performance of the architecture in terms of physical layer parameters (loss analysis, power analysis and noise analysis), packaging volume and optical cost is done.
