Specific embodiments of the embodiments of the present invention.

S001: ECN1 is powered on, reads the configured ECNO information, organizes a Setup Request message, and sends the message to the ECNO;

S002: After receiving the ECL1 Setup Request message, the ECNO determines whether the ECNO is within the jurisdiction. Then read the basic information of ECN1 and select the security algorithm. According to the configuration of the ECNO, it is decided whether to carry the network topology information in the response message. Then organize the Setup Response and send it to ECN1;

S003: After receiving the Setup Response, ECN1 determines whether the sender is the correct ECNO. Then check to see if the chain is built successfully. If the chain fails to be built, the corresponding retry, alarm, notification, etc. are processed according to the failure code. If the link is successful, check if there is network topology information. If the value of the IsNetworkInfoExist field is Yes, the network topology information is saved and the contiguous ECN is started. If the IsNetworkInfoExist field has a value of No, it waits for a Network Info message. If the Network Info message is not received within a certain period of time, the chain building process is re-initiated;

S004: After receiving the Network Info information, ECN1 saves the network topology information to the local area. Then start looking for a neighboring ECN. After the search process ends, if there is a neighboring ECN node, the local network topology information is updated and the Network Info Update message is sent to the ECNO;

S005: The newly discovered ECN node of the ECN1 organizes and sends a Network Info Update message to the ECNO according to the locally updated network topology information after updating and saving the information of the ECN1;

S006: After receiving the Network Info Update message, the ECNO waits for the Network Info Update message of the other party's ECN according to the content of the message. If the message is received, it means that the two parties are interworking and update the local network topology message. If the message is not received, the Network Info message is sent to both parties to initiate the search process.
