In step 105, data back is extracted to installing equipment from dummy node；Fig. 4 is this step schematic diagram.Mainly set
Three processes of score：After the Internet of node receives the data from MAC layer, judge whether the node is half node in kind, is
Half node in kind then sends the data to data processing unit, is otherwise routed directly to application layer；Data processing unit processing receives
Data, and it is packaged into the network data consistent with installing equipment form；Data are sent to reality by data processing unit by tunnel
Install standby；Described decision node whether be half node in kind method for check the node whether with node in kind map, with
The node of node mapping in kind is accordingly indicated that it is half node in kind to have the node accordingly indicated；Described is direct
It is sent to application layer and refers to layered architecture in simulation software, existing simulation software has layered architecture mostly, if
The node for receiving business datum is dummy node rather than half node in kind, then is transferred to its upper layer application, upper strata to its whether
Forwarding is carried out to be judged；Data back is referred to encapsulate data into by the data processing unit to installing equipment to be set with actual load
The consistent network data of standby form, the i.e. decapsulation to transmitting data in virtual network, reduce actual services data format.
Further, the installing equipment and the data transmission tunnel of data processing unit established is to pass through：
Installing equipment sends tunnel building request to data processing unit；Installing equipment is sending tunnel to data processing unit
Road needs to obtain tunnel relevant information, such as the source in the tunnel, purpose, bandwidth demand, and tunnel path before establishing request
Etc. information, these information are produced by control management equipment or human configuration planning, data processing unit receive from installing equipment
Control message, and tunnel building request is obtained from the control message, it can also include reservation mode in tunnel building request
Field, the field are used to indicate the mode taken when subsequently carrying out RSVP, are specifically as follows fixed form, or shared
Mode, fixed form are the certain bandwidth of fixed occupancy, and the bandwidth uses only for current business, and sharing mode is reserved
Bandwidth can be shared according to occupancy and other business.
Whether data processing unit confirmation request data format is correct, obtains bandwidth demand and judges the idle money of own node
Whether source meets bandwidth demand；
Data processing unit bandwidth resource, and the tunnel path in being asked by tunnel building establishes swap table；
Data processing unit is responded to corresponding band to installing equipment passback tunnel building response, installing equipment by tunnel building
Width is reserved, and reserved completion confirmation is sent to data processing unit.
