Unit is completing, if message byte number during the first overhead processing increases, judging unit judges offset for just, offset
Absolute value be equal to the byte number increase numerical value absolute value；If message byte number in the first overhead processing is reduced, sentence
Disconnected offset is negative, and the absolute value of offset is equal to the absolute value that the byte number reduces numerical value.
In this step, if judge module judges offset for just, the first positive justification unit in the first adjusting module
The data descriptor of the message data is transferred, and message length value therein is deducted into the absolute value of offset.If judge module
Judge that offset is negative, then the first negative justification unit in the first adjusting module transfers the data descriptor of the message, and by its
In message length value plus offset absolute value.
Additionally, after this step is completed, it is further comprising the steps of：Traffic shaping compensation is enabled and offset is mapped to
In the data descriptor.In order to be able to enable subsequent module quickly to process message accordingly, need to mend traffic shaping
Repay enable and offset is mapped to data descriptor, so that subsequent module is operated to message data.
Step 308：Data descriptor after modification is added in flow shaping dispatching queue；Into step 310.
Step 310：Data descriptor is dispatched successfully, during into the state of transmission, reads the data descriptor, and according to institute
State the message length value that offset recovers modification；Into step 312.
In this step, if offset is just, the second positive justification unit reads data descriptor, by data descriptor
Absolute value of the message length value of record plus the offset.If offset is negative, the second negative justification unit reads the number
According to descriptor, the message length value recorded in data descriptor is deducted into the absolute value of the offset.Although reality now
Message data length is differed with the message length value in flow shaping dispatching, but is also needed before message data sends to report
Text carries out the second overhead processing.So processing procedure now can guarantee that message length after the second overhead processing with
Message length during flow shaping dispatching is identical, and the loss ratio of message and the utilization rate of bandwidth are reduced with this.
Step 312：According to the data descriptor after recovery, corresponding message data is read, and carry out the to message data
Two overhead processings；Into step 314.
In this step, the inverse operations of the first overhead processing is carried out to message data, i.e., message data is added before message
Leading code and frame period, add FCS, peel off subport Vlan.So that message can be normally carried out sending.
Step 314：Send newly-generated message.
