| Abstract: | ION is a new generation optical network which can complete automatic switching and linking function under the control of optical routing and signaling.It is considered as the trend of optical transmission network and gets more and more focus under the dual drive of transmission bandwidth and service application demand .First the configuration characteristic of current intelligent optical network is introduced and analyzed in this paper. And then on the base of a new generation ION model namely the combination of GMPLS and ASON, the protection and restoration technologies and the survival tactics based on extended GMPLS signaling are mainly discussed. |
