The embodiment of the invention provides a kind of methods of data transmission, as shown in Figure 1, comprising:
S101, data to be transmitted and its mark transmitted by sender are obtained.
Wherein, the data to be transmitted with same mark belongs to the same transmission transaction.It is also understood that same mark
Data to be transmitted belong to the same big data or same file.So in the embodiment of the present invention, data to be transmitted is
Sub-fraction composition data in the big data of transmission transaction.
It should be noted that baseboard management controller (Baseboard Management Controller, BMC) is usual
(Advanced eXtensible Interface, the AXI) bus used carries out the transmission of data.5 are defined in AXI bus
A independent transmission channel: data channel, write address channel, write data channel, write response channel are read in read address channel.Respectively
It is used for transmission and reads the address of data, the address read data, write data, writes data, write response signal, it is a large amount of can quickly transmit
Data.Address, the size of data of the address and write response signal of writing data for reading data are smaller, usually will not all deposit cash
The case where blocking, thus present invention is generally directed to be the address transmission read in data channel and write data channel.
Due to the characteristic of AXI bus protocol, so the size for the data transmitted each time all no more than 4KB, so logical
The data to be transmitted that the data of a normal transmission transaction need to be divided under multiple comparisons is transmitted.In order to accelerate the biography of data
It is defeated, all data to be transmitted of transmission transaction all can't just be transmitted next biography after transmission in a transmission channel
The data to be transmitted of defeated affairs, but the data to be transmitted of different transmission transactions is transmitted simultaneously.And pass through different identification
To mark different numbers to be transmitted to distinguish the data of different transmission transactions.So also being needed while obtaining data to be transmitted
Obtain mark to be transmitted.
S102, a buffer zone is determined from transmission channel, and data to be transmitted is buffered in buffer zone.
It wherein, include multiple buffer zones in transmission channel, the data to be transmitted of different identification is stored in different cachings
In region.
It should be noted that data to be transmitted is transferred to by corresponding transmission channel from sender and is connect in AXI bus
Debit is not one to need finally to get to connect by multiple buffer memory devices among the transmission of data to be transmitted
Debit.So, it is believed that it in a transmission channel include multiple buffer memory devices.But in the same buffer memory device,
There is no divide buffer zone.In a buffer memory device, as long as guaranteeing the data to be transmitted of same mark, the orderly transmission of energy
To next buffer memory device.It is set so being all optionally buffered in caching relatively for the data to be transmitted of different marks
In standby.Therefore, there is transmission abnormality and is just easy to influence the to be transmitted of other identifier in the data to be transmitted identified when some one
The normal transmission of data.
The embodiment of the present invention has divided different buffer zones, will be to be transmitted with can be by the mark based on data to be transmitted
Data carry out orderly caching, and can transmit the data to be transmitted of different identification is independent.Specifically, being sent out in sender
Out when a data to be transmitted, a buffer zone will be determined from multiple buffer zones.Wherein, the buffer area determined
There is also the memories that can cache data to be transmitted in domain.Then, data to be transmitted is cached in determined buffer zone,
Data to be transmitted is transferred to recipient from buffer zone again.
S103, the data to be transmitted being buffered in the buffer zone is transferred to recipient.
Wherein, the transmission of the data to be transmitted of different identification is independent of one another.The data to be transmitted of like-identified is according to caching
Sequencing successively transmitted.
Due to, multiple buffer zones have been divided, the data to be transmitted of different identification is buffered in different buffers, and
Buffer zone is independently from each other, it is possible to data to be transmitted are transferred to recipient from buffer zone respectively, realized not
With the individual transmission of the data to be transmitted of mark.But for the data to be transmitted of same mark, it is necessary to orderly pass
It is defeated, with allow recipient it is orderly receive data to be transmitted, so as to correctly be built into the data to be transmitted of same mark
The big data of one completion.
Also, due to be when determining that reception can normally receive data to be transmitted, could be by data to be transmitted from caching
Area transmissions are to method of reseptance, if so recipient's transmission exception, can not receive data to be transmitted, then data to be transmitted
It is only to block its buffer zone cached, and other buffer zones and unaffected.So that in the biography of some data
When output is existing abnormal, the normal transmission of other data will not be influenced.
The method of data transmission provided in an embodiment of the present invention, by the way that multiple buffer zones, In are arranged in transmission channel
When receiving the data to be transmitted of sender's transmission, the data to be transmitted of different identification is cached in different buffer zones,
Then the data to be transmitted cached is transferred to recipient respectively from buffer zone again.Also, different identification is to be transmitted
Data are independent of each other to recipient from caching area transmissions, and the data to be transmitted of same mark is then according to the successive of caching
Sequence is successively transmitted.Thus under the premise of guaranteeing the data to be transmitted order transfer of the same mark, by different numbers
According to transmission it is independent of one another.So that other data will not be being influenced just when the transmission of some data occurs abnormal
Often transmission.
Another embodiment of the present invention provides a kind of methods of data transmission, as shown in Figure 2, comprising:
S201, data to be transmitted and its mark transmitted by sender are obtained.
Wherein, the data to be transmitted with same mark belongs to the same transmission transaction.
It should be noted that the specific implementation process of this step can be accordingly with reference to the step in above method embodiment
S101, details are not described herein again.
S202, buffer zone corresponding with the mark of the data to be transmitted is determined from transmission channel, and will be to be passed
Transmission of data is cached in buffer zone.
Wherein, each buffer zone is only used for caching the data to be transmitted of corresponding mark.
That is, in embodiments of the present invention, buffer zone is divided according to the mark of data to be transmitted.Difference mark
The data to be transmitted of knowledge is only capable of being buffered in and identify in corresponding buffer zone with it.
Optionally, as shown in figure 3, a mark corresponds to a buffer zone, and the buffer zone can cache simultaneously
The data to be transmitted of multiple corresponding marks.It is of course also possible to regard the corresponding multiple small buffer zones of a mark as, and
And multiple small buffer zones join end to end, and collectively constitute a big buffer zone.Also, a buffer zone is only used for delaying
The data to be transmitted for depositing a mark, to be more convenient for transmitting the order transfer of the data to be transmitted of same mark.
Specifically, being determined from multiple buffer zones in transmission channel after receiving data to be transmitted and its mark
Buffer zone corresponding with the mark of data to be transmitted out, and data to be transmitted is cached in the buffer zone.Wherein, same
The transmission of the data to be transmitted of mark must be orderly, so as to receive data to be transmitted can be reverted to it is one complete big
Data.So optionally, the data to be transmitted of same mark, according to the sequencing of caching, is arranged successively in buffer zone
It is buffered in buffer zone, the data to be transmitted of same mark to be successively transferred to recipient.If in transmission channel, not
Include buffer zone corresponding to the mark, then distribute certain memory, creates buffer zone corresponding with the mark, and
Data to be transmitted is buffered in created region.
It should be noted that when the memory of the buffer zone corresponding to a certain mark has all been occupied full, because of buffer area
Domain can not cache the data to be transmitted of the mark again, so sender is can not to handle the data to be transmitted transmission of the mark
, so not will cause the obstructing problem in transmission process.
S203, the data to be transmitted with like-identified that will be cached in buffer zone, the sequencing of foundation caching, according to
It is secondary to be transferred to recipient.
Since in the transport protocol of AXI bus, the transmission of the data to be transmitted of different identification can be unordered.But
What the data to be transmitted of same mark must be ordered into.So being transferred to from buffer zone by the data to be transmitted of same mark
When recipient, the sequencing according to data to be transmitted caching is needed to be transmitted, to guarantee the data to be transmitted of same mark
It is ordered into.The data to be transmitted more first cached also more first will be transferred to recipient from buffer zone.Specifically, same
The data to be transmitted of mark is arranged successively and is buffered in buffer zone, as long as so according to row according to the tandem of caching
The sequence of caching is arranged according to transmission data to be transmitted, just realizes the order transfer of the data to be transmitted of same mark.
The method of data transmission provided in an embodiment of the present invention, by the way that the mark with data to be transmitted is arranged in transmission channel
Know corresponding buffer zone, when receiving the data to be transmitted of sender's transmission, data to be transmitted is cached to it and identifies institute
In corresponding buffer zone, the data to be transmitted cached is successively then transferred to recipient from buffer zone again.Also,
The data to be transmitted of different identification from caching area transmissions is independent of each other, and the data to be transmitted of same mark to recipient
Then successively transmitted according to the sequencing of caching.To before the data to be transmitted order transfer for guaranteeing the same mark
It puts, the transmission of different data is independent of one another.So that will not be influenced when the transmission of some data occurs abnormal
To the normal transmission of other data.
