In above-mentioned steps 201, the first microwave station takes out the byte stream of preset length from data packet transmit queue, and in institute
The byte stream of preset length is stated plus data frame is formed after frame head, which is then the minimum for needing to be sent to the second microwave station
Unit, i.e. the first microwave station are to send data to the second microwave station as unit of a data frame.
Wherein, data frame packet contains frame head and data two parts, and data portion is the byte stream of preset length, specific default length
The selection of degree is decided according to the actual requirements, and frame head part includes the frame number code for being used to indicate the data frame assembling sequence, it
So the frame head in data frame increases frame number code, it is to guarantee that the second microwave station is receiving a large amount of of the first microwave station transmission
After data frame, it can be correctly assembled into data packet, i.e. the second microwave station needs the frame number code of the frame head by means of data frame
Carry out restoring data packet.In addition, also include other information in the frame head of data frame, such as data frame length, check code etc., data frame
Length is used for the total length of mark data frame, and check code is for verifying the correctness of data frame.
Therefore, by step 201, the first microwave station generates data frame after can taking out byte from data packet transmit queue,
It and include the frame number code for being used to indicate data frame assembling sequence in the frame head of each data frame.
In above-mentioned steps 202, the first microwave station selects one in multiple data frame transmit queues, then by the number of generation
According to frame buffer to the data frame transmit queue of selection.Wherein, the quantity of the quantity of data frame transmit queue and microwave Member Link
It is identical, and be one-to-one, for example have n microwave Member Link (n is greater than 1) between microwave station, then there is n in the first microwave station
A data frame transmit queue, and each data frame transmit queue by corresponding microwave Member Link send data frame to
Second microwave station.Therefore in step 202, the first microwave station can cache the data frame of generation to n number according to certain method
According in frame transmit queue, specifically, by a data frame buffer memory to which data frame transmit queue, method is relatively more, for example, can
To be the sequence by queue number from small to large, by data frame buffer memory to data frame transmit queue, until data frame transmit queue
Team is full, and then by data frame buffer memory to next data frame transmit queue, the benefit of this method is that algorithm comparison is simple, is easy real
It is existing, but disadvantage is also it will be apparent that be exactly microwave Member Link load imbalance, and some microwave Member Links are very busy, and
Some microwave Member Links are then very idle, cause overall data efficiency of transmission very low, therefore offer of the embodiment of the present invention is following
The transmitting efficiency of microwave Member Link can be improved to the method for data frame transmit queue in data cached frame
Optionally, first microwave station selects one from multiple data frame transmit queues, by the data frame buffer memory
To the data frame transmit queue of selection, comprising:
First microwave station determines that the data frame for capableing of data cached frame in the multiple data frame transmit queue is sent
Queue；
If the quantity for capableing of the data frame transmit queue of data cached frame is greater than 1, first microwave station is according in advance
The method of setting selects one from the data frame transmit queue for capableing of data cached frame, and by the data frame buffer memory
To the data frame transmit queue of selection；
If the quantity for capableing of the data frame transmit queue of data cached frame is equal to 1, first microwave station is by the number
According to frame buffer to the data frame transmit queue for capableing of data cached frame.
In this method, the first microwave station is determined to the data frame hair of data cached frame from multiple data frame transmit queues
Send queue, if it is possible to which the quantity of the data frame transmit queue of data cached frame is greater than 1, such as one shared n data frame and sends
Queue, wherein have k number according to frame transmit queue can data cached frame, k be less than or equal to n, and k be greater than 1, then from this k energy
One is selected in the data frame transmit queue of enough data cached frames, and the data frame of the data frame buffer memory to selection is sent into team
In column, if it is possible to which the quantity of the data frame transmit queue of data cached frame is equal to 1, then the first microwave station delays the data frame
It deposits to the data frame transmit queue for capableing of data cached frame.As long as thus the above method, which ensure that currently to have, can cache number
According to the data packet transmit queue of frame, so that it may therefrom select one, then data frame buffer memory gets off.In compared with the existing technology
Data frame is uniquely corresponding according to type of service and some data frame transmit queue, when corresponding data frame queue team is full, then not
The cache way of the data frame of the type is cached again, and aforesaid way provided in an embodiment of the present invention can guarantee to work as number of data frames
When more, all data frame transmit queues are not in that some is busier, and the situation that some comparisons are idle, but all
Data frame transmit queue load balancing, utmostly use upper all data frame transmit queues.
For how to be determined in the above method which data frame transmit queue can data cached frame, following side can be passed through
Method:
Optionally, first microwave station determines the data for capableing of data cached frame in the multiple data frame transmit queue
Frame transmit queue, comprising:
For one in the multiple data frame transmit queue, first microwave station sends team according to the data frame
The team leader of the maximum length of column and the data frame transmit queue determines the residue length of the data frame transmit queue；
If the residue length of the data frame transmit queue is not less than preset data frame maximum length, described the
One microwave station determines that the data frame transmit queue being capable of data cached frame.
In the above method, for a data frame transmit queue, first according to the maximum length of data frame transmit queue and
The team leader of data frame transmit queue determines the residue length of data frame transmit queue, for example, it is assumed that preset data frame is most
Long length is 300 bytes, some data frame transmit queue is capable of the maximum length of data cached frame data frame transmit queue
The team leader of 1000 bytes, the data frame transmit queue is 600 bytes, then shows that the data frame transmit queue is currently buffered
The data of 600 bytes can also cache the data of 400 bytes again, therefore the residue length of the data frame transmit queue is 400
Byte is 300 bytes since the residue length of the data frame transmit queue is greater than preset data frame maximum length, then
The data frame transmit queue can data cached frame, if the team leader of the data frame transmit queue be 800 bytes, the data frame
Residue length is 200 bytes, then the data frame transmit queue can not data cached frame.
Wherein, preset data frame maximum length is equal to the byte obtained in step 201 from data packet transmit queue
The preset length of stream adds the length of frame head, it is assumed that the first microwave station takes 200 byte streams from data packet transmit queue every time, so
The frame head for adding 50 bytes again afterwards generates a data frame, then preset data frame maximum length is exactly 250 bytes,
In most cases, the length of a data frame is fixed, such as 250 bytes in the example, only in a small number of feelings
Under shape, the length of a data frame is less than the total length of the byte stream in the regular length, such as data packet transmit queue
Less than the preset data frame maximum length, then it is preset that the total length of the data frame generated is just less than this
Data frame maximum length.
In the above method, if the quantity for capableing of the data frame transmit queue of data cached frame is greater than 1, the first microwave station root
According to preset method, one is selected from the data frame transmit queue for capableing of data cached frame, and by the data
How frame buffer is specifically selected to the data frame transmit queue of selection from multiple data packet transmit queues for capableing of data cached frame
One is selected, there are many method, for example randomly choose, or select according to queue number, for example selection queue number is the smallest, selection
Queue number is maximum or other way.But for guarantee all data packet transmit queue can load balancing, the present invention
Embodiment provides a kind of method selected from the data frame transmit queue for capableing of data cached frame, as follows:
