Word 0 indicates.On the basis of may be implemented to distinguish indicates between node device with the presence or absence of connection relationship, the present embodiment is to used
Character style be not especially limited.
According to the difference of deployed with devices in different data centers, the device type for including in physical map is also not quite similar.
Different types of node device can have differences, for example, connection degree of the different types of node device in physical map may
Difference, the connection degree refer to the quantity for other node devices connecting with each node device；Belong to the number of same layer node device
Amount is that the quantity of same type of node device may be different, therefore, can be based on the node device of connection degree and same type
The factors such as quantity are layered the node device in physical map, and each layer corresponds to a device type, to realize node
