RMAnum=(Mnum-Ms1)/(Rnum-Rs1)；
And then combining default internal memory upper limit value M max, it is determined that second estimated resets entry number Rnum3, for:
Rnum3=Mmax/RMAnum。
Further, obtain second reset entry number Rnum3 after, according to default entry higher limit Rmax, this second is reseted entry number Rnum3 is judged:
If this second resets entry number Rnum3 more than or equal to default entry higher limit Rmax, then assert that this second resets entry number Rnum3 beyond the set point of equipment under test, for unavailable, then perform S209 step operation, the maximum entry number Rnum currently set is set as the routing capacity of equipment under test；
Or, if this second resets entry number Rnum3 less than default entry higher limit Rmax, then assert that this second resets the entry number Rnum3 set point without departing from equipment under test, second that maximum entry number Rnum is then updated to new acquisition resets entry number Rnum3, even after Rum=Rnum3, re-execute S205 step operation, control the route table items that equipment under test study number is the maximum entry number Rnum after updating, and learning outcome is judged。
