's.
When routing algorithm least using the first described intermediate equipment, reaches target in more each transmission paths and set
After standby, the remainder of detecting label；Remainder is bigger, then the intermediate equipment that transmission path is passed through is fewer, and transmission path is shorter.Choosing
Selecting the maximum transmission path of outgoing label volume residual is transmission path.
When the routing algorithm for being less than threshold value using intermediate equipment number described in second, source device sends tag-detection frame,
If the path may be selected as transmission road it was found that the intermediate equipment number for having a transmission paths to reach target device is less than threshold value
Diameter.In this way, the intermediate equipment number passed through without more each transmission paths, without each transmission paths of waiting
Detection is completed, to be conducive to the quick selection of transmission path, and selects face relatively wider, when wherein a transmission paths occur
Failure can choose other transmission paths and carry out WIFI communication, without always according to route selection algorithm, determining same
