Fig. 2 be can be constructed as into network traffic matrix, i.e. Fig. 3 on the basis of business traversal method based on flow conservation, wherein, work as business
Treat that the value of cutover network is defined as 1 from certain node inflow/outflow, be otherwise 0.It is, communication service is two-way, flow into and
Outflow be while.This node of business inflow/outflow is exactly business by other networks or the customer equipment inflow/outflow section
Point, is the network node of upper and lower business, is worth for 1.Otherwise situation refers to the node that the node is business approach, not up and down
Business.
In figure 3, row vector t1、t2、t3、t4And t5Represent business 1 in business i.e. Fig. 2, business 2, business 3 etc..It is vertical
Vectorial A to F represents network node, i.e. substation A, substation B and control centre station F in Fig. 2 etc..
Then job location eigenmatrix, network traffic matrix table are obtained by the feature vector of calculating network traffic matrix
Levy in all cutover work, business both ends job location information.
For example, in fig. 2, it is seen that there are three business, respectively business 1, business 2, business 3.Wherein, business 1 is from E
Node is to A nodes (E and A are lower node in business)；2 approach C-D-F-B nodes of business, C and B are lower node in business, D and F
Node is approach node；3 approach C-A-B nodes of business, C and B node are lower nodes in business, and A nodes are business approach sections

The interim construction node of first day is substation A, substation B, substation C, central station E, construction volume 62.Then remove A,
B, the side between C and E nodes obtains Fig. 6.
Then, the node of node degree maximum is found in present node, wherein, node degree refers to and the node is associated
Side bar number, i.e. D (A) in Fig. 5 arrives the value that D (F) is represented, degree is be used for stating node degree of being completely embedded in graph theory one
Mathematical feature, its computational methods be exactly be connected with this node side and.Specifically calculation formula is：Assuming that there is N in figure
A node set is V={ V1, V2 ..., Vn }, carries M bar business in figure, the degree of node A is D (A), then
The node degree of the node of B, C, D and E is maximum in Figure 5, when the corresponding node of node degree maximum has multiple, then
Any one processing for carrying out next step is chosen wherein, is chosen E nodes in the present embodiment and is corresponded to as node degree maximum
Node, and find out the adjacent nodes of node E, since the node of single treatment is 4, then choosing adjacent number of nodes is
3, according to the node degree information in each node in the service source destination node topological diagram, the node of node degree maximum is chosen,
And the node of the node degree maximum node adjacent with the node of node degree maximum is formed into the first subgraph, described in calculating
