First control unit, for when first frame error rate is more than or equal to the default frame error rate, by actual schedule weights
The second scheduling weights are reduced to from the described first scheduling weights.
7. node device as claimed in claim 6, it is characterised in that first control unit specifically includes：
First obtains subelement, for when first frame error rate is more than or equal to the default frame error rate, based on described first
Frame error rate, obtains the first compensation share；
First control subelement, for based on the described first compensation share, actual schedule weights to be dispatched weights from described first
It is reduced to the second scheduling weights.
8. node device as claimed in claim 6, it is characterised in that the node device further includes：
Second judging unit, for when first frame error rate is less than the default frame error rate, judging the first connection team
Whether row are hysteresis connection queues；
Second obtaining unit, for when the described first connection queue is the hysteresis connection queue, obtaining for the first compensation moment
Second frame error rate at the first moment before, wherein, the first compensation moment is less than the default mistake for the first time for frame error rate
At the time of frame per second.
9. node device as claimed in claim 8, it is characterised in that the node device further includes：
3rd obtaining unit, for based on second frame error rate, obtaining the second compensation share；
Second control unit, for based on the described second compensation share, actual schedule weights to be carried from the described first scheduling weights
It is high to dispatch weights to the 3rd.
10. node device as claimed in claim 8, it is characterised in that the node device further includes：
3rd control unit, for when the described first connection queue is not the hysteresis connection queue, keeping actual schedule power
It is worth for the described first scheduling weights.
