Banyan óptico empilhado verticalmente (VSOB) é uma arquitetura atraente para a construção de switches ópticos baseados em banyan. A análise de comportamentos de bloqueio é uma abordagem eficaz para estudar o desempenho da rede e encontrar um compromisso elegante entre custos de hardware, probabilidade de bloqueio e tolerância a diafonia; entretanto, pouco tem sido feito na análise do comportamento de bloqueio de redes VSOB sob restrição de crosstalk, o que adiciona uma nova dimensão ao desempenho de comutação. Neste artigo, estudamos o comportamento geral de bloqueio de uma rede VSOB sob vários graus de crosstalk, onde é desenvolvido um limite superior para a probabilidade de bloqueio da rede. O limite superior representa com precisão o comportamento geral de bloqueio de uma rede VSOB, conforme verificado por extensos resultados de simulação, e concorda com a condição estritamente sem bloqueio da rede. O limite superior derivado é significativo porque revela a relação inerente entre a probabilidade de bloqueio e o custo de hardware da rede, pelo qual uma compensação desejável pode ser feita entre eles sob vários graus de restrição de diafonia. Além disso, o limite superior mostra como o crosstalk adiciona uma nova dimensão à teoria dos sistemas de comutação.

Abstract: Vertically stacked optical banyan (VSOB) is an attractive architecture for constructing banyan-based optical switches. Blocking behaviors analysis is an effective approach to studying network performance and finding a graceful compromise among hardware costs, blocking probability and crosstalk tolerance; however, little has been done on analyzing the blocking behavior of VSOB networks under crosstalk constraint which adds a new dimension to the switching performance. In this paper, we study the overall blocking behavior of a VSOB network under various degree of crosstalk, where an upper bound on the blocking probability of the network is developed. The upper bound depicts accurately the overall blocking behavior of a VSOB network as verified by extensive simulation results and it agrees with the strictly nonblocking condition of the network. The derived upper bound is significant because it reveals the inherent relationship between blocking probability and network hardware cost, by which a desirable tradeoff can be made between them under various degree of crosstalk constraint. Also, the upper bound shows how crosstalk adds a new dimension to the theory of switching systems.
