step 2-4: and transmitting the license message polling instruction to the license message proxy unit I, so that the license message proxy unit I prepares sufficient license messages for the license message proxy unit II according to the license message polling instruction.

In a preferred but non-limiting embodiment of the present invention, a method for refreshing the highest standard license message number of a license message agent II according to the equipped number includes:

under the condition that more than 1 allocation number is over zero, namely under the condition that the second allocation unit of the license message is allocated with enough license messages in the latest P allocation periods, the amount obtained by adding the highest allocation number to the highest standard license message number is taken as the highest standard license message number after refreshing.

Under the condition that the total allocation number is zero, the highest standard license message number is refreshed to a preset amount, and if no license message is allocated in the latest P allocation periods, the own requirement is not high or the total sufficient license message number does not exist, at the moment, the capacity (balance standard amount) of the license message pool is restored to the initial amount, namely the preset amount, namely the highest standard license message number.

To make the number of insufficient license messages more close to the specific requirement of throughput, a method for flexibly changing the capacity (constant reference quantity) of a license message pool is introduced, and the technical route is that license messages allocated to own are related to the requirement of the next transmission, so that the next transmission can allocate to the license messages with higher quantity; the highest standard license information number is set to be very high without starting, and for uniformity, each own license information pool is subjected to standard quantity starting inquiry, and if the total sufficient license information quantity is not small, then the license information pools are gradually changed in an efficient and gradual mode.

The state when the capacity of the permission message pool is not changed, the balance reference quantity is positioned at the initial preset point, the balance reference quantity is increased according to the number of more than 1 allocation, and the balance reference quantity is returned to the source site because the P allocation periods are not allocated to the permission message.

The number of insufficient license messages (close to the actual throughput requirement) transmitted according to the method is determined according to the number of sufficient license messages allocated in the recent P allocation periods, and when the total sufficient license messages are not enough, the own requirement can be effectively improved, and the allocation uniformity of the license messages can be improved.
