Step 501: compare anticipation network link information and real network link information, obtain inconsistent network connection information;
Step 502: judge whether exist first network to connect in the said inconsistent network connection information, if exist, the information that then first network is connected is added in the anticipation network link information execution in step 503 to; Otherwise, execution in step 503;
Said first network connection is meant: source node and/or destination node connect for the network of newly-increased node;
Step 503: judge whether exist second network to connect in the said inconsistent network connection information, if confirm that said second network connects to break down execution in step 504; Otherwise, direct execution in step 504;
Said second network connection is meant: source node that network connects and/or the destination node node for reducing.
Above-mentioned newly-increased or minimizing is meant: current real network is newly-increased or minimizing with respect to the network of expection.
Wherein, after then definite second network connected, can further include: whether the node of judging said minimizing was in the state of not closing down, if confirm that then corresponding second network connection of node of not closing down is in malfunction; Do not connect the possible breakdown state that is in if, then confirm the second corresponding network of node of closing down.
Here, the determining step execution sequence of step 502 and step 503 does not limit.
Step 504: in inconsistent network connection information, the information except that first network connection information and second network connection information confirms that the network that said information identifies connects the possible breakdown state that is in.
In above step shown in Figure 5, network is connected branch for three kinds of situation, a kind of is that the corresponding network of newly-increased node connects, and determines that it is normal condition; A kind of is the possible breakdown state; Also having a kind of is the fault state.
Step 204: the network that will confirm to be in malfunction connects to be connected to the user with the network that is in the possible breakdown state and represents; And source node that the network of malfunction and possible breakdown state is connected and the physical location under the destination node represent to the user simultaneously.
Here; The said mode that represents does not limit; For example directly on a certain interface the all-network to user's display network connect; And the network that will wherein be in malfunction connects and the network of possible breakdown state connects and uses different implementations to show to the user respectively, for example uses various colors, different lines etc., as long as can let the user with network bonding pads such as normal condition, malfunction and possible breakdown states separately.Here, in practical application, also normal condition and malfunction can only be set, at this moment, normal condition is incorporated in the connection of the network of possible breakdown state into or malfunction can independently be set according to applied environment.
For example, shown in Fig. 6～7, be respectively the different Display Realization that network connects, and for a certain node, the demonstration that its network that makes a mistake connects.The demonstration respectively that the network that in Fig. 6, uses different lines to carry out normal condition and malfunction is connected; And in Fig. 7, the mode through underscore then, the network that node ISW22 is broken down connects and has carried out outstanding demonstration.
