Abstract:
1. A control method for cross-domain connection of Automatic Switched Optical Network, wherein a multi-layer network structure including both parent domain and child domain is firstly established; there is at least one network element in the parent domain corresponding to one child domain and able to communicate with network elements in the child domain; the network element in the parent domain is configured with parameters of the network elements in the corresponding child domain; boundary links of the child domain are input and output links of the corresponding network element in the parent domain; the optical network domain without child domain is called bottom-layer domain; each network element includes a connection controller CC; one successful cross-domain connection processing includes the following steps of: (a) an input connection controller CC (b) CC (c) CC when the CC (d) after CC wherein, when the parent domain CC (c1) CC (c2) after CC (c3) after completing the SNC processing in the child domain D, CC in the above sub-connection processing, when the CC on the sub-connection routing L
