Specific implementation method
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Fig. 1 is the Microwave Emulsifier-Free Polymerization link schematic diagram in background technology between microwave station, is simultaneously applicable to the present invention, and each microwave station has the ability sending data and reception data simultaneously.When microwave station is as data receiver, microwave station is called the first microwave station；When microwave station is as data receiver, microwave station is called the second microwave station.Data parallel transmitting-receiving can be carried out by n microwave Member Link between microwave station.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
When the embodiment of the present invention introduces microwave station as data receiver by step 201～203, the method sending data, and when introducing microwave station as data receiver by step 401～step 404, the method receiving data.
As in figure 2 it is shown, the data packet sending method flow chart that the embodiment of the present invention provides, including:
Step 201, the first microwave station take out the byte stream of preset length from packet transmit queue, and by the byte stream of described preset length plus forming Frame after frame head；
Step 202, described first microwave station select one from multiple Frame transmit queues, by described data frame buffer memory to the Frame transmit queue selected；
Step 203, for each Frame transmit queue, the Frame in described Frame transmit queue is sent successively to the second microwave station by described first microwave station by the microwave Member Link corresponding with described Frame transmit queue.
When microwave station is as data receiver, it is referred to as the first microwave station, the first microwave station has a packet transmit queue, for the data that buffer memory receives, therefore alternatively, before above-mentioned steps 201,
First microwave station obtains packet；
Described packet is formed the first Frame plus the first frame head by described first microwave station, and with the form of byte stream, described first Frame is stored described packet transmit queue.
First microwave station first obtains packet, can be that other microwave station sends over, it can also be the first microwave station active obtaining, the type of the packet that the first microwave station obtains is not limit, can be such as IP packet, TCP (TransmissionControlProtocol, transmission control protocol) packet, UDP (UserDatagramProtocol, UDP) packet, HTTP (HyperTextTransferProtocol, HTML (Hypertext Markup Language)) packet etc., the type of the packet for getting does not limit.
First microwave station is after getting packet, described packet is formed the first Frame plus the first frame head, wherein the first frame head can include the information such as data frame length, type of service, port numbers, check code, then the first Frame is stored in packet transmit queue with the form of byte stream, therefore this queue is all byte stream, packet do not distinguished mutually.Therefore the embodiment of the present invention do not have any restriction for the type of packet, because being all store to packet transmit queue with the form of byte stream.
In above-mentioned steps 201, first microwave station takes out the byte stream of preset length from packet transmit queue, and form Frame after the byte stream of described preset length adds frame head, this Frame is then the least unit needing to be sent to the second microwave station, and namely the first microwave station sends data to the second microwave station in units of a Frame.
Wherein, data frame packet is containing frame head and data two parts, data division is the byte stream of preset length, choosing of concrete preset length is decided according to the actual requirements, frame header subpackage is containing being used for indicating the frame number code of described Frame assembling sequence, why increase frame number code at the frame head of Frame, it is for ensureing that the second microwave station is after receiving the mass data frame that the first microwave station sends, can being correctly assembled into packet, namely the second microwave station needs to carry out restoring data bag by means of the frame number code of the frame head of Frame.Additionally, also include out of Memory in the frame head of Frame, such as data frame length, check code etc., data frame length is for identifying the total length of Frame, and check code is for verifying the correctness of Frame.
Therefore, by step 201, the first microwave station can generate Frame after taking out byte from packet transmit queue, and includes the frame number code for indicating Frame assembling sequence in the frame head of each Frame.
In above-mentioned steps 202, the first microwave station selects one from multiple Frame transmit queues, the Frame transmit queue then extremely selected by the data frame buffer memory generated.Wherein, the quantity of Frame transmit queue is identical with the quantity of microwave Member Link, and be one to one, such as there is n microwave Member Link (n is more than 1) between microwave station, then there is n Frame transmit queue in the first microwave station, and each Frame transmit queue is by corresponding microwave Member Link transmission Frame to the second microwave station.nullTherefore in step 202，First microwave station can by the Frame of generation according in certain method buffer memory to n Frame transmit queue，Specifically，By a data frame buffer memory to which Frame transmit queue，Method is relatively more，Such as，Can be by queue number order from small to large，By data frame buffer memory to Frame transmit queue，Until Frame transmit queue team is full，Then by data frame buffer memory to next Frame transmit queue，The benefit of the method is that method comparison is simple，Easily realize，But shortcoming is also readily apparent from，It it is exactly microwave Member Link load imbalance，Some microwave Member Links are very busy，Some microwave Member Links are then very idle，Cause that overall data efficiency of transmission is very low，Therefore the embodiment of the present invention provides following data cached frame to the method for Frame transmit queue，The transmitting efficiency of microwave Member Link can be improved
Alternatively, described first microwave station selects one from multiple Frame transmit queues, by described data frame buffer memory to the Frame transmit queue selected, including:
Described first microwave station is determined in the plurality of Frame transmit queue can the Frame transmit queue of data cached frame；
If can the quantity of Frame transmit queue of data cached frame more than 1, then described first microwave station is according to method set in advance, the Frame transmit queue of data cached frame can select one from described, and by described data frame buffer memory to the Frame transmit queue selected；
If can the quantity of Frame transmit queue of data cached frame equal to 1, then described first microwave station by described data frame buffer memory to described can the Frame transmit queue of data cached frame.
In the method, first microwave station is determined to the Frame transmit queue of data cached frame from multiple Frame transmit queues, if able to the quantity of the Frame transmit queue of data cached frame is more than 1, such as one total n Frame transmit queue, wherein there is the k can data cached frame according to frame transmit queue, k is less than or equal to n, and k is more than 1, then the Frame transmit queue of data cached frame can select one from this k, and by described data frame buffer memory to the Frame transmit queue selected, if able to the quantity of the Frame transmit queue of data cached frame is equal to 1, then the first microwave station by described data frame buffer memory to described can the Frame transmit queue of data cached frame.As long as thus said method ensure that currently have can the packet transmit queue of data cached frame, it is possible to therefrom select one, then data frame buffer memory is got off.Uniquely corresponding with certain Frame transmit queue according to type of service relative to Frame in prior art, when corresponding data frame queue team is full, the then cache way of the no longer Frame of buffer memory the type, the aforesaid way that the embodiment of the present invention provides can ensure that when number of data frames is more, it is busy that all of Frame transmit queue does not have the comparison having, and the situation that some comparisons is idle, but all of Frame transmit queue load balancing, at utmost use upper all of Frame transmit queue.
For how said method is determined which Frame transmit queue can data cached frame, can by following method:
Alternatively, described first microwave station determine in the plurality of Frame transmit queue can the Frame transmit queue of data cached frame, including:
For one in the plurality of Frame transmit queue, the team leader of the greatest length according to described Frame transmit queue of described first microwave station and described Frame transmit queue, it is determined that the residue length of described Frame transmit queue；
If the residue length of described Frame transmit queue is not less than Frame greatest length set in advance, then described first microwave station determines that described Frame transmit queue can data cached frame.
nullIn said method，For a Frame transmit queue，First the team leader according to the greatest length of Frame transmit queue and Frame transmit queue，Determine the residue length of Frame transmit queue，Such as，Assume that Frame greatest length set in advance is 300 bytes，Certain Frame transmit queue can 1000 bytes of greatest length of data cached frame data frame transmit queue，The team leader of this Frame transmit queue is 600 bytes，Then show the current buffered data of 600 bytes of this Frame transmit queue，Can also the data of buffer memory 400 byte again，Therefore the residue length of this Frame transmit queue is 400 bytes，Owing to the residue length of this Frame transmit queue is 300 bytes more than Frame greatest length set in advance，Then this Frame transmit queue can data cached frame，If the team leader of this Frame transmit queue is 800 bytes，Then the residue length of this Frame is 200 bytes，Then this Frame transmit queue can not data cached frame.
Wherein, Frame greatest length set in advance adds the length of frame head equal to the preset length of the byte stream obtained from packet transmit queue in step 201, assume that the first microwave station takes 200 byte streams every time from packet transmit queue, then the frame head of upper 50 bytes is added again, generate a Frame, then Frame greatest length set in advance is exactly 250 bytes, in most cases, the length of one Frame is all fixing, 250 bytes in such as this example, only under rare cases, the length of one Frame is less than this regular length, the total length of the byte stream in such as packet transmit queue is less than this Frame greatest length set in advance, the total length of the Frame then generated just is less than this Frame greatest length set in advance.
In said method, if can the quantity of Frame transmit queue of data cached frame more than 1, then the first microwave station is according to method set in advance, the Frame transmit queue of data cached frame can select one from described, and by described data frame buffer memory to the Frame transmit queue selected, specifically how the packet transmit queue of data cached frame can select one from multiple, method is a lot, such as randomly choose, or select according to queue number, such as select queue number minimum, select queue number maximum, or alternate manner.But for ensure all of packet transmit queue can load balancing, the embodiment of the present invention provides a kind of from the method that can select the Frame transmit queue of data cached frame, as follows:
Alternatively, described first microwave station, according to method set in advance, can select one the Frame transmit queue of data cached frame from described, including:
Described first microwave station determine described can the minimum Frame transmit queue of the Frame transmit queue squadron officer of data cached frame；
If the quantity of the Frame transmit queue that team leader is minimum is equal to 1, then described first microwave station selects the Frame transmit queue that described team leader is minimum；
If the quantity of the Frame transmit queue that team leader is minimum is more than 1, then described first microwave station is according to method set in advance, selects one from the Frame transmit queue that multiple team leaders are minimum.
nullUnder this methodology，Assume that one has 20 Frame transmit queues，The Frame transmit queue being currently able to data cached frame has 5，Assume respectively the 2nd Frame transmit queue S2，4th Frame transmit queue S4，7th Frame transmit queue S7，9th Frame transmit queue S9，18th Frame transmit queue S18，Due to one have 5 can the Frame transmit queue of data cached frame，Assuming that the team leader of these 5 Frame transmit queues is respectively as follows: S2 team leader is 500 bytes，S4 team leader is 500 bytes，S7 team leader is 600 bytes，S9 team leader is 800 bytes，S18 team leader is 500 bytes，Then currently there is the Frame transmit queue that 3 team leaders are minimum，Respectively S2，S4，S18，Then from these 3 Frame transmit queues, select one and carry out data cached frame，Specifically chosen which，Can select according to queue number，Alternatively，Described first microwave station is according to method set in advance，One is selected from the Frame transmit queue that multiple team leaders are minimum，From the minimum Frame transmit queue of multiple team leaders, the minimum Frame transmit queue of the queue number of correspondence is selected including: described first microwave station；Or, described first microwave station selects the Frame transmit queue that the queue number of correspondence is maximum from the minimum Frame transmit queue of multiple team leaders.
Therefore in the method, it is that the minimum Frame transmit queue of team leader carrys out data cached frame due to what select, therefore can ensure that all of Frame transmit queue duty factor is more balanced, do not have a fast team of Frame transmit queue full, and other Frame transmit queue also compares empty situation, thereby may be ensured that when sending Frame, load balancing between multiple microwave Member Links, it is ensured that transmit data efficiently.
In above-mentioned steps 203, for each Frame transmit queue, the Frame in described Frame transmit queue is sent successively to the second microwave station by the first microwave station by the microwave Member Link corresponding with described Frame transmit queue.
