英文摘要：

With the development of high-speed optical transmission technology,100 Gbit/s or higher all-optical networks have become crucial.This paper proposes ultrahigh-capacity all-optical network architecture based on flexible spectrum use.In this architecture,the bandwidth of optical channels can be set up according to the actual port rate,and all-optical switching can be implemented.This new architecture can overcome problems of limited fixed-channel bandwidth in wavelength division multiplexing（WDM）networks and in the ultra high-speed optical transport.The new architecture supports fine-granularity control and management technologies used for segmenting and grooming in all-optical frequency domains.It also implements virtualization and on-demand allocation for optical-layer resources so that bandwidth use is optimized.
