Step S3: send this high-priority data message.
When the data message of confirming to receive has high priority,, all it is sent no matter whether the token quantity in the current time token bucket can satisfy the demand of this data message.
Step S4: confirm first token number that this high-priority data message takies.
Each token allows to send the data of specific quantity, after the data volume of specified data message, can confirm the token number that this data message takies.For example, each token allows to send the data of 1 byte, and when sending the data message of K byte, this data message takies K token.When data message is the high-priority data message, its token number that takies is designated as first token number.
Step S5: utilize first token number to upgrade the token total amount of token bucket.
The process of upgrading is specially, and before sending this high-priority data message, confirms the token total amount of token bucket, and the computational token total amount and first token number is poor afterwards, with the token total amount of this difference as new token bucket.
Step S6: confirm second token number that this lower-priority data message takies.
Step S7: the token total amount of obtaining the current time token bucket.
Step S8: judge second token number whether greater than the token total amount of token bucket, if, execution in step S10 then, otherwise, execution in step S9.
Step S9: send this lower-priority data message, utilize second token number to upgrade the token total amount of token bucket.
Step S10: handle this lower-priority data message according to preset strategy.
When the data message that receives is the lower-priority data message, it is handled according to conventional method.Handling the lower-priority data message according to preset strategy can be to abandon this data message, can be that it is emitted in the formation, so that when running up to abundant token in the token bucket, transmit, perhaps also can carry out sending behind the special marking to it again.
