V. Routing Process
This implementation part is the performance of the entire system, if integrated with the communication simulation system, this section is not required. So this part is written for individual debugging. In order to verify the route analog system, a single packet routing process is written. But semantics are basically complete. If this is achieved in the communication simulation system, you can synchronize the detailed expansion design.
1, single packet routing
Method Name: Communication :: SingleDatarout
Method parameters: no
Return value: no
The purpose of the method: implement a single data package by the whole process of successful success, and may have several network reconstruction during the period.
Possible error: no
