In the first embodiment, taking the IP RAN network structure formed by the system structure shown in fig. 11 as an example, the process of the present invention is as follows:
step 1101: the access node A1, or A2, or A3 encapsulates the port type and state information of itself into a port information sub TLV, and sends the port type and state information to the corresponding management node B1 or standby management node B2.
Step 1102: after receiving the port type and state information reported by the access node a1, or a2, or A3, the management node B1 or the standby management node B2 determines whether the message is the protocol information message for automatic configuration and management described in this patent according to the TCP port number (e.g., 2000) or the ECP Sub-type (e.g., 0x03) in the port type and state information, and if so, performs a corresponding PW encapsulation mode and parameter configuration operation according to the port type, identifier, and state encapsulated therein.
Step 1103: the management node B1 or the standby management node B2 packages the parameters and command data (such as ID or cluster ID assigned to each access node a1, a2, and A3), the configuration information related to PW emulation (such as PWType, PW ID, or PW Label), and the encapsulation mode of emulation service in Type, length, Value (TLV, Type Value) and the configuration command of TCP specific port number (such as 2000) or ECP subtype (Sub-Type) (such as 0x03), and sends the configuration command to the access node a1, a2, or A3.
Step 1104: when the access node A1, or A2, or A3 receives the TCP/ECP message sent by the management node B1 or the standby management node B2, the message is decapsulated and analyzed, and a response message is returned to the management node B1 or the standby management node B2.
Specifically, whether the information encapsulated by the TCP/ECP is the protocol information message of the automatic configuration and management described in the patent is judged according to the port number (such as 2000) used in the TCP message or the Sub-Type (such as 0x03) used on the ECP, and if so, the information in the message is analyzed; if the TLV type can be identified, if the TLV type can not be identified or the parameter is wrong, returning a receiving confirmation message of wrong information to the opposite management node B1 or B2; if the parameter command can be identified or the parameter command is correct, the corresponding parameter configuration and command operation is executed, and a parameter or command correct response message is returned to the management node B1 or the standby management node B2.
Step 1105: the management node B1 or the standby management node B2 determines whether a response packet fed back by the access node a1, or a2, or A3 is received, and if so, executes step 1107; otherwise, step 1106 is performed.
Step 1106: if the management node B1 or the standby management node B2 still does not receive the response message fed back by the access node a1, or a2, or A3 within a certain time, the management node B1 or the standby management node B2 performs the retransmission operation of the TCP/ECP message; if no response message fed back by the access node A1, or A2, or A3 is received after 3 times of continuous retransmission, or a failure in connection between the access node and the management node is detected, the parameter or command data to be configured is issued and configured by the standby node B2 through a TCP/ECP protocol, and the processing flow is ended.
Step 1107: when the management node B1 or B2 receives the response message of parameter error fed back by the access node, the relevant configuration error information is reported to the NMS/EMS system, and then the correct parameters and commands are issued and managed; and if the received response message with the correct parameters is the response message with the correct parameters, starting the issuing operation of the next parameter or management command.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
