Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
An embodiment of the present invention provides a data transmission method, as shown in fig. 1, including:
s101, acquiring data to be transmitted and an identification thereof sent by a sender.
The data to be transmitted with the same identification belong to the same transmission transaction. It can also be understood that the data to be transmitted with the same identifier belong to the same large data or the same file. Therefore, in the embodiment of the present invention, the data to be transmitted is a small part of the large data of the transmission transaction.
Note that an Advanced eXtensible Interface (AXI) bus, which is generally used by a Baseboard Management Controller (BMC), transfers data. The AXI bus defines 5 independent transmission channels: the device comprises a read address channel, a read data channel, a write address channel, a write data channel and a write response channel. The data transmission device is used for transmitting the address of read data, the address of read data and write data, the address of write data and the write response signal respectively so as to quickly transmit a large amount of data. The addresses of the read data, the addresses of the write data and the data size of the write response signals are small, and the situation of congestion usually cannot occur, so the invention mainly aims at address transmission in a read data channel and a write data channel.
Due to the characteristics of the AXI bus protocol, the size of data transmitted each time cannot exceed 4KB, so that the data of one transmission transaction needs to be divided into a plurality of data to be transmitted under comparison for transmission. In order to accelerate the data transmission, all the data to be transmitted of a transmission transaction cannot be transmitted in one transmission channel, the data to be transmitted of the next transmission transaction is transmitted after all the data to be transmitted of the transmission transaction are transmitted, and the data to be transmitted of different transmission transactions are transmitted simultaneously. And marking different numbers to be transmitted through different identifications so as to distinguish data of different transmission transactions. Therefore, the identifier to be transmitted needs to be acquired while the data to be transmitted is acquired.
S102, determining a buffer area from the transmission channel, and buffering the data to be transmitted in the buffer area.
The transmission channel comprises a plurality of cache regions, and the data to be transmitted with different identifications are stored in different cache regions.
It should be noted that, in the AXI bus, data to be transmitted is not transmitted from a sender to a receiver through a corresponding transmission channel, and the data to be transmitted needs to pass through a plurality of buffer devices in the middle of transmission, and finally reaches the receiver. Therefore, it can be considered that a plurality of buffer devices are included in one transmission channel. However, in the same cache device, the cache area is not divided. In one cache device, data to be transmitted with the same identifier can be transmitted to the next cache device in order. Therefore, data to be transmitted for different identifications are relatively randomly buffered in the buffer device. Therefore, when the data to be transmitted of one identifier is abnormal in transmission, the normal transmission of the data to be transmitted of other identifiers is easily affected.
The embodiment of the invention divides different cache regions so as to orderly cache the data to be transmitted based on the identification of the data to be transmitted and independently transmit the data to be transmitted with different identifications. Specifically, when the sender sends a data to be transmitted, a buffer area is determined from the plurality of buffer areas. And the determined cache region also has a memory which can cache the data to be transmitted. And then, caching the data to be transmitted into the determined cache region, and transmitting the data to be transmitted to a receiver from the cache region.
S103, transmitting the data to be transmitted cached in the cache region to a receiver.
Wherein, the transmission of the data to be transmitted with different identifications is independent. And sequentially transmitting the data to be transmitted with the same identification according to the sequence of the cache.
Because a plurality of buffer areas are divided, the data to be transmitted with different identifications are buffered in different buffers, and the buffer areas are independent from each other, the data to be transmitted can be respectively transmitted to a receiver from the buffer areas, and the independent transmission of the data to be transmitted with different identifications is realized. However, for the data to be transmitted with the same identifier, the data must be transmitted in order, so that the receiver can receive the data to be transmitted in order, and the data to be transmitted with the same identifier can be correctly constructed into a finished large data.
Moreover, since the data to be transmitted can be transmitted from the buffer area to the receiving method only when it is determined that the receiving party can normally receive the data to be transmitted, if the receiving party sends an exception and cannot receive the data to be transmitted, the data to be transmitted only blocks the buffer area buffered by the receiving party, and other buffer areas are not affected. Therefore, when the transmission of certain data is abnormal, the normal transmission of other data can not be influenced.
In the data transmission method provided by the embodiment of the invention, the plurality of buffer areas are arranged in the transmission channel, when the data to be transmitted sent by the sender is received, the data to be transmitted with different identifications are buffered in different buffer areas, and then the buffered data to be transmitted are respectively transmitted to the receiver from the buffer areas. And the data to be transmitted with different identifications are transmitted to the receiver from the cache region independently, and the data to be transmitted with the same identification are transmitted in sequence according to the sequence of the cache. Therefore, on the premise of ensuring the ordered transmission of the data to be transmitted with the same identifier, the transmission of different data is independent. Therefore, when the transmission of certain data is abnormal, the normal transmission of other data can not be influenced.
Another embodiment of the present invention provides a method for data transmission, as shown in fig. 2, including:
s201, acquiring data to be transmitted and an identification thereof sent by a sender.
The data to be transmitted with the same identification belong to the same transmission transaction.
It should be noted that, the specific implementation process of this step may refer to step S101 in the foregoing method embodiment, and details are not described here.
S202, determining a cache region corresponding to the identifier of the data to be transmitted from the transmission channel, and caching the data to be transmitted into the cache region.
Each cache region is only used for caching the data to be transmitted of the corresponding identification.
That is, in the embodiment of the present invention, the buffer area is divided according to the identification of the data to be transmitted. Data to be transmitted with different identifications can only be cached in the cache region corresponding to the identification thereof.
Alternatively, as shown in fig. 3, one identifier corresponds to one cache region, and the cache region may cache a plurality of pieces of data to be transmitted corresponding to the identifiers at the same time. Of course, it can also be regarded that one identifier corresponds to a plurality of small cache regions, and the plurality of small cache regions are connected end to form a large cache region together. In addition, one cache region is only used for caching the data to be transmitted of one identifier, so that the ordered transmission of the data to be transmitted of the same identifier is more convenient to transmit.
Specifically, after receiving the data to be transmitted and the identifier thereof, a cache region corresponding to the identifier of the data to be transmitted is determined from a plurality of cache regions in the transmission channel, and the data to be transmitted is cached in the cache region. The transmission of the data to be transmitted with the same identification must be ordered, so that the receiving party can restore the data to be transmitted into a complete large data. Therefore, optionally, the data to be transmitted with the same identifier are sequentially cached in the cache region according to the caching sequence, so that the data to be transmitted with the same identifier can be sequentially transmitted to the receiving party. If the transmission channel does not include the cache region corresponding to the identifier, allocating a certain memory, creating the cache region corresponding to the identifier, and caching the data to be transmitted in the created region.
It should be noted that, when the memory of the cache region corresponding to a certain identifier is full, the cache region cannot cache the data to be transmitted of the identifier any more, so that the sender cannot send and process the data to be transmitted of the identifier, and therefore, the problem of blocking in the sending process is not caused.
And S203, sequentially transmitting the data to be transmitted with the same identification cached in the cache region to a receiver according to the caching sequence.
Since, in the transmission protocol of the AXI bus, the transmission of data to be transmitted of different identities may be out of order. But the data to be transmitted of the same identity must be ordered. Therefore, when the data to be transmitted with the same identifier is transmitted to the receiver from the buffer area, the data to be transmitted with the same identifier needs to be transmitted according to the sequence of the data to be transmitted buffer so as to ensure that the data to be transmitted with the same identifier is ordered. I.e. the data to be transmitted that is buffered earlier will also be transmitted from the buffer area to the receiver earlier. Specifically, the data to be transmitted of the same identifier are sequentially cached in the cache region according to the front-back sequence of the cache, so that the ordered transmission of the data to be transmitted of the same identifier is realized only by transmitting the data to be transmitted according to the sequence of the cache arrangement.
In the data transmission method provided by the embodiment of the invention, the buffer area corresponding to the identifier of the data to be transmitted is arranged in the transmission channel, when the data to be transmitted sent by the sender is received, the data to be transmitted is buffered in the buffer area corresponding to the identifier of the data to be transmitted, and then the buffered data to be transmitted is sequentially transmitted to the receiver from the buffer area. And the data to be transmitted with different identifications are transmitted to the receiver from the cache region independently, and the data to be transmitted with the same identification are transmitted in sequence according to the sequence of the cache. Therefore, on the premise of ensuring the ordered transmission of the data to be transmitted with the same identifier, the transmission of different data is independent. Therefore, when the transmission of certain data is abnormal, the normal transmission of other data can not be influenced.
An embodiment of the present invention provides a data transmission method, as shown in fig. 4, including:
s401, data to be transmitted and an identification thereof sent by a sender are obtained.
The data to be transmitted with the same identification belong to the same transmission transaction.
It should be noted that, the specific implementation process of this step may refer to step S101 in the foregoing method embodiment, and details are not described here.
S402, determining any buffer area in an idle state from the plurality of buffer areas in the transmission channel.
The idle state refers to that memory cache data still exists in the cache region or data is not cached. That is to say, in the embodiment of the present invention, the fixed cache region is no longer configured according to the identifier of the data to be transmitted. Each cache region can cache any identified data to be transmitted. Therefore, all cache regions can be effectively utilized, and waste of the memory is avoided.
S403, caching the data to be transmitted into a cache region, and configuring an address identifier for the data to be transmitted according to the cache position of the data to be transmitted.
Because, in the embodiment of the present invention, the data to be transmitted can be cached in any cache region. Therefore, different data to be cached with the same identifier can be cached in different cache regions. And in order to realize that the data to be transmitted with the same identification are transmitted according to the sequence of cache, so as to ensure the ordered transmission of the data to be transmitted with the same identification. Therefore, the embodiment of the invention uses the principle of linked list storage for reference. Caching the data to be transmitted into a cache region, configuring a unique address identifier for the data to be transmitted according to the specific address position of the cache of the data to be transmitted, and realizing the ordered transmission of the data to be transmitted with the same identifier based on the address identifier.
S404, pointing the data to be transmitted meeting the first condition to the address identification of the data to be transmitted.
The first condition is that the cache sequence is only prior to the data to be transmitted of the data to be transmitted, wherein the data to be transmitted has the same identification with the data to be transmitted.
Specifically, after the received data to be transmitted is cached in the cache area and the address identifier is configured. And pointing the data to be transmitted which is cached last time and has the same identification with the data to be transmitted to the address identification of the cached data to be transmitted. Specifically, a pointer may be configured for the data to be transmitted, and the pointer may be used to enable the data to be transmitted cached last time to point to the address identifier of the data to be transmitted cached this time. The data to be transmitted in the same cache will point to the address identifier of the data to be transmitted with the same identifier in the next cache. As shown in fig. 5, in the embodiment of the present invention, the to-be-transmitted data of the same identifier are connected to each other according to the sequence of the cache through the address identifier and the pointer.
S405, after the data to be transmitted meeting the first condition in the cache region is transmitted, the data to be transmitted is transmitted to a receiver according to the address identification pointed by the cache region meeting the first condition.
That is to say, for the transmission of the data to be transmitted with the same identifier, after the transmission of one data to be transmitted is finished, the address identifier pointed by the data to be transmitted which is finished to be transmitted is determined, and the corresponding data to be transmitted is transmitted. Namely, the data to be transmitted with the same identification is transmitted according to the address identification and the pointer direction of the data to be transmitted. Because the data to be transmitted of the same identifier are mutually connected according to the sequence of the cache, the ordered transmission of the data to be transmitted of the same identifier is realized through the transmission mode of the step.
According to the data transmission method provided by the embodiment of the invention, the plurality of cache regions are arranged in the transmission channel, when the data to be transmitted sent by the sender is received, the data to be transmitted with different identifications are cached in different cache regions, and the address identification is configured for the data to be transmitted. And sequentially transmitting the data to be transmitted with the same identifier to a receiver from the buffer area through the address identifier. And the data to be transmitted with different identifications are transmitted to the receiver from the cache region independently, so that the transmission of different data is independent on the premise of ensuring the ordered transmission of the data to be transmitted with the same identification, and the normal transmission of other data cannot be influenced when the transmission of certain data is abnormal.
