The notice transfer module of registration service abstraction layer, which services corresponding network device management service model for notice, different
Business function service model that correspondence is different, which will generate respective service request return information and network configuration pipe
Reason strategy.It requests return information to generate in step 304, arrives step 308, request return information will will do it interface position, interface
It will position and be to report in the identical port in request port, in step 311, manager will request return information to be sent to net
Element device.On the other hand, step 306, requested network equipments configuration management service model will match new network management
In the DataStore for setting strategy write-in network manager.Next in step 307, network configuration management service model will be supervised
The variation for hearing DataStore, is read out related data, and then model is combined with network demand.Step 309, net
Network configuration admin service model will issue corresponding network management configuration strategy and give request routing, and request routing will be the net
Network management configuration strategy is positioned with the southbound interface library being related to.In step 310, manager southbound interface will be to network
Management strategy information carries out serializing operation.Finally, in step 312, by PacketOut data packet by network configuration management
Strategy is sent on the network element device being related in network.
Fig. 4 show the present invention in the realization stream of industrial converged network manager processes isomery Industrial Ethernet equipment access
Journey exemplary diagram.Method 400 is by the 1 access industrial converged network of equipment step 401, under Industrial Ethernet a Networking protocol.?
In step 402, converged network manager periodically will send Topology Discovery data message to converged network, thus, it is found that newly
The Industrial Ethernet a equipment 1 of access.Equipment 1 sends access request message, and in step 403, industrial converged network manager is logical
Service abstraction layer is crossed, calls the protocol identification function in southbound interface library a corresponding to industrial ethernet protocol a to the request report
Text is identified and is parsed.If industrial ethernet protocol a equipment 1 is not configured network protocol, enter step
404, converged network manager will access the unknown network equipment and alert, to ensure the safety of converged network.Such as
Fruit industrial ethernet protocol a equipment is the network protocol being configured, then in step 405, converged network manager will
Network configuration management strategy correspondingly can be generated, and be located in southbound interface library according to configuration management model.?
In step 406, manager will send PackOut number to all network element devices being related in the network configuration management strategy
According to message, change the forwarding strategy in current network equipment, and then meets the communication requirement of Industrial Ethernet a protocol devices 1, it is complete
At access operation.
