The situation (S2) of window region is sent, average transmission item number s items/second is taken, as s ＜ S2, takes S3=s.Meanwhile in order to avoid alarm is sent out
It send window region too small, rule of thumb takes the accessible transmission lower alarm threshold threshold value ss of system, as S3 ＜ ss, take S3=ss.It can
, it is envisioned that when reducing alarm transmission window region, more to meet the network state after alarm windstorm is pass by.
The third situation：It is constant that alarm sends window region.
If within the cycle, buffer area has overstocked c ＞ 0, but overstocks non-superthreshold c ＜ CC, then alerts transmission window region
It need not adjust.
By the training in several cycles, alarm sends the big I of window region and is matched with network state, and can be according to network
The variation of state adjusts in real time.System processing power and real-time in order to balance can set adjustment to refresh week according to actual conditions
