COLLISION-FREE FAULT TOLERANT MULTISTAGE INTERCONNECTION NETWORKS BASED ON WAVELENGTH DIVISION MULTIPLEXING
In this paper, the performance of the extra stage Omega (ESO) networks based on wavelength division with limited number of buffers and wavelength converters was analyzed. Since the ESO networks suffer from the problem of internal blocking, therefore, the goal is to minimize the dropping probability by utilizing the available buffers and wavelength converters in the central controller of these networks. The advantage of ESO over the Omega networks is that there is a redundant path from any source to any destination. Having an additional path gives packets more flexibility, thus reducing the probability of packet buffering or dropping.
Strategic units at the various levels of the cyberspace, from the personal level to the world level, through the enterprise and the country levels, need to protect their information security.
Grid computing is emerging as the foundation upon which virtual organizations can be built. Such organizations are becoming of increasing importance for tackling various projects, both in academic…
In this paper, methods to alleviate the problem of internal blocking in interconnection networks based on WDM are studied. In an ordinary 8x8 Omega network, only 10% of all permutations are…
