Whether inspection exists said second timing signal sign, if exist, judges then whether the bag sequence number of the packet of a transmission on bag sequence number and this set of queues of the current packet that needs to send of said each set of queues is continuous;
For discontinuous set of queues, the said bag sequence number that this set of queues is preserved is updated to the current bag sequence number that needs the packet of transmission of this set of queues, and the corresponding packet of said bag sequence number that sends and preserve;
For continuous set of queues, judge the said bag sequence number whether said bag sequence number that this set of queues preserves preserves smaller or equal to other set of queues, if be judged as not; Then judge pre-determined number continuously; If still be judged as not, then remove said second timing signal sign, wait for regularly next;
If judge the said bag sequence number that the said bag sequence number of this set of queues preservation is preserved smaller or equal to other set of queues; Then send the corresponding packet of said bag sequence number of this set of queues and preservation, and upgrade the bag sequence number that the said bag sequence number of preserving be the packet of next one needs transmission;
If also having packet in each set of queues waits to send out; Then judge the said bag sequence number whether said bag sequence number that this set of queues preserves preserves less than other set of queues; If be judged as be; The corresponding packet of said bag sequence number that then abandons and preserve, and the said bag sequence number that renewal is preserved is the bag sequence number that the next one needs the packet of transmission;
Remove said second timing signal sign, wait for regularly next.
