| 摘 要： | 对光分组交换中每条链路共享波长转换器(SPL,share-per-link)的结构进行了理论分析,推导出SPL系统的丢包率公式,并对系统丢包率与负载、输入光纤端口数和每纤波长数的关系进行了数值计算.结果表明:SPL的丢包率极限是随着波长数的增加而减小,在SPL结构中当波长转换器数目较小且一定时,波长数大的系统的丢包率比波长数小的系统要大.

| Abstract: | The scheme based on SPL wavelength conversion was analyzed in theory and the formulation of packet loss probability in this scheme was deduced.Simulations on the relationship between the packet loss probability and load,the port number of input fiber and the number of wavelength per fiber were carried out.Simulation results indicate the packet loss probability of SPL reduces with the increase of the number of wavelength.When the number of wavelength converters in SPL is small and definite,the packet loss pr... |
