the system single channel transmission rate has evolved from 10Gbit/s
40Gbit/s to 100Gbit/s
so the DWDM system capacity is no longer a bottleneck in the network development.Hence
end-toend dynamic configuration and scheduling and the network security and utilization improvement have become the focus of attention.This paper briefly describes the key technologies for Wavelength Switched Optical Networks(WSON)
verifies the WSON functions through the trial network and explores the strategies for its applications.
