Description

TECHNICAL FIELD

[0002] In the prior art, an RDMA (Remote-Direct Memory Access) link is divided into an admin management queue and multiple IO (Input / Output) queues. The admin queue is mainly used for transmitting management commands, and the IO queue is used for transmitting data. For each IO queue, the process of sending an IO command or data is serial. When the first command is transmitted to the receiving end, the receiving end receives and processes the command and then returns a status (referred to as the execution result of the command) to the sending end. After receiving the status of the command, the sending end sends the second command according to the result. The sending end is referred to as an initiator, and the receiving end is referred to as a target. Therefore, for a single IO queue, the speed of transmitting commands or data is limited by many factors. When the network has a delay, the sending time of the next command is greatly delayed, which ultimately leads to low performance.

[0003] As can be seen from the above, how to increase the performance of command transmission and improve the efficiency of command transmission is a problem to be solved in the field. SUMMARY

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0042] In the prior art, an RDMA (Remote-Direct Memory Access) link is divided into one admin management queue and multiple IO (Input / Output) queues. The admin queue is mainly used to transmit management commands, and the IO queue is used to transmit data. For each IO queue, the process of sending an IO command or data is serial. When the first command is transmitted to the receiving end, the receiving end receives and processes the command and then returns a status (referred to as the execution result of the command) of the command to the sending end. The sending end receives the status of the command and then sends the second command according to the result. The sending end is referred to as an initiator, and the receiving end is referred to as a target. Therefore, for a single IO queue, the speed of transmitting a command or data is limited by many factors. When the network has a delay, the sending time of the next command is greatly delayed, and finally the performance is not high. As can be seen from the above, how to increase the performance of command transmission and improve the efficiency of command transmission is a problem to be solved in the field.

[0043] Referring to Figure 1 The embodiments of the present application disclose a command transmission method, which can specifically include:

[0044] Step S11: Obtain a command to be transmitted, and determine a transmission sequence.

[0045] In the embodiment, before obtaining the command to be transmitted, the Internet protocol address is invoked and the Internet protocol address is parsed for network smoothness. If the network is smooth, the connection request is obtained, the routing request is invoked, and the routing request is parsed based on the connection request. If the routing is normal, the connection resource information is obtained. The connection command is invoked, the connection command is used to establish the remote memory direct access connection relationship between the local and the receiving end based on the connection resource information. Specifically, the connection command is invoked, and the connection command is sent to the receiving end, so that the receiving end responds to the connection command after obtaining the connection command. If the response is successful, information indicating that the remote memory direct access connection relationship between the local and the receiving end is successfully established is generated, and the information is sent to the local.

[0046] In the embodiment, the IO queue is created in a multi-threaded manner based on the remote memory direct access connection relationship, and the counting function is added to the IO queue. Then, the command to be transmitted is obtained, the command is sent to the IO queue, and the transmission order of the command is determined according to the counting function.

[0047] Specifically, first, an admin queue (connection) is created, and the connection mode depends on the specific RDMA API (0Application Programming Interface, application programming interface) and CM (Connection Management, connection management) event. The initiator initiates to set the target ip to be connected, and initiates to establish the connection. After the admin queue is created, IO queues are created in turn, and the number of IO queues is defined according to the upper layer protocol, for example, 8 IO queues. The sending end initiates the connection step: first, rdma_resolve_addr (Internet Protocol Address, Internet Protocol Address) is called to resolve the IP address, and the RDMA_CM_EVNET_ADDR_RESOLVED event (connection request) will be received under the condition that the network is smooth. If the network is not smooth, the RDMA_CM_EVNET_ADDR_ERROR event will be received. Then, after receiving the RDMA_CM_EVNET_ADDR_RESOLVED event, rdma_resolve_route (route request) is called to resolve the route request, and the RDMA_CM_EVNET_ROUTE_RESOLVED event represents that the route is normal. Otherwise, the RDMA_CM_EVNET_ROUTE_ERROR event will be received, and the connection resource information required for creating the queue is created by calling the rdma_create_cq, rdma_create_qp and other API interfaces, and then rdma_connect (connection command) is called to initiate the connection request. After the initiator initiates rdma_connect, the target receives the connection request, and the processing steps are as follows: the target receives the RDMA_CM_EVENT_CONNECT_REQUEST event, and then the target creates the required resources by calling the rdma_create_cq, rdma_create_qp and other API interfaces, and the target calls rdma_accept to respond to the connection request of the initiator. After the above steps are completed, the target and the initiator will receive the RDMA_CM_EVNET_ESTABLISHED event (information for indicating that the remote memory direct access connection relationship between the local and the receiving end is successfully established), and thus a CM connection is established. According to the above connection establishment steps, the admin connection and the IO connection are established. Different IO queues can send command data on different threads to achieve concurrency, and the more the number of threads, the more the CPU consumption.The transmission efficiency of the single IO queue is still limited. The following scheme is designed for the single IO queue to improve the performance. First, a CID attribute is created on the IO queue to count the current transmitted commands. The count value can be set to 0 to 4095.

[0048] Step S12: A unique identifier is added to each command according to the transmission order to obtain each target command, and each target command is sent to the receiving end, so that the receiving end processes the target command after obtaining the target command and generates a return result.

[0049] Step S13: The return result sent by the receiving end is obtained, and the return result is parsed. If the return result is successful, the next transmission order to be transmitted is determined based on the transmission order corresponding to the last target command in the return result.

[0050] In this embodiment, if the return result is a failure, the transmission order corresponding to the target command that fails to be processed is determined based on the return result, then the transmission order corresponding to the target command that fails to be processed is used as the next transmission order to be transmitted, and the target command that fails to be processed is used as the next target command to be transmitted, then the above operation is repeated until all the target commands are processed.

[0051] Step S14: The next target command to be transmitted is determined according to the next transmission order to be transmitted, and the next target command to be transmitted is sent to the receiving end, so that the receiving end processes the target command to be transmitted until all the target commands are processed.

[0052] In the embodiment, a command to be transmitted is acquired, and a transmission sequence is determined. A unique identifier is added to each command according to the transmission sequence, to obtain each target command. Each target command is sent to a receiving end, so that the receiving end processes the target command after acquiring the target command, and generates a return result. The return result sent by the receiving end is acquired, and the return result is parsed. If the return result is successful, the transmission sequence corresponding to the last target command in the return result is determined as the next transmission sequence to be transmitted. The next target command to be transmitted is determined according to the next transmission sequence to be transmitted, and the next target command to be transmitted is sent to the receiving end, so that the receiving end processes the target command to be transmitted. The above process is repeated until all target commands are processed. The application transmits commands to the receiving end one by one, and each command carries a unique identifier. The receiving end processes the command, and then generates a return result. The sending end receives the return result, and decides whether to retransmit a command or continue to send the next group of commands according to the return result, until all commands are processed. The performance of command transmission is improved, and the efficiency of command transmission is improved.

[0053] Referring to Figure 2 The embodiment of the application discloses a command transmission method, which can specifically include the following steps:

[0054] Step S21: acquiring a command to be transmitted, and determining a transmission sequence.

[0055] Step S22: adding a unique identifier to each command according to the transmission sequence, to obtain each target command, and sending each target command to a receiving end, so that the receiving end processes the target command after acquiring the target command. If all target commands are successfully processed, a return result to be sent is generated, and the transmission sequence corresponding to the last target command is determined. The transmission sequence corresponding to the last target command is added to the return result to be sent, to obtain a return result.

[0056] In the embodiment, after each target command is sent to the receiving end, the sending time is recorded, and it is judged whether the time interval between the current time and the sending time is greater than a preset response threshold. If the time interval between the current time and the sending time is greater than the preset response threshold, it is determined that each target command is sent unsuccessfully, and a command retransmission operation is performed.

[0057] In this embodiment, the initiator sends commands can send five consecutive commands to the target (each command occupies a cid count, such as the first five commands correspond to cid: 0, 1, 2, 3, 4), start a timer. The purpose of the timer is to send commands to the target if the target does not respond to the status, wait for the timer to time out after the timer expires, consider the command sending failure, and resend the command group. After the target receives the command and starts processing, the continuous 5 commands are processed, and if all 5 commands are correctly processed, the status structure is filled, the result is set to success, the cid is set to the last command cid (cid is set to 4), and the status is sent to the initiator. After the initiator receives the status, the result is success, which indicates that the command sending is successful, and the cid is 4. Then send the next group of commands with cid 5, 6, 7, 8, 9 to the target for processing. If the target fails when processing the command with cid 8, the result of the status is set to fail, and the cid is set to 8. Send the status to the initiator. After the initiator receives the status, the result is fail, and the cid is 8, which indicates that the command with cid 8 fails. The initiator sends the next group of commands starting from the command with cid 8, and sends the commands with cid 8, 9, 10, 11, 12 to the target. According to the above manner, all commands are processed, and if the cid count is 4095, the counting is restarted from 0. According to the above manner, five consecutive commands are sent to the target for processing, and the target returns the status only once after processing. In this way, the number of status transmissions can be greatly reduced, thereby improving transmission efficiency and achieving the purpose of improving performance.

[0058] Step S23: Obtain the return result sent by the receiving end, and analyze the return result. If the return result is success, the next transmission order to be transmitted is determined based on the transmission order corresponding to the last target command in the return result.

[0059] Step S24: Determine the next target command to be transmitted according to the next transmission order to be transmitted, and send the next target command to be transmitted to the receiving end, so that the receiving end processes the target command to be transmitted until all the target commands are processed.

[0060] The present application defines a field for recording the command id in the command structure when transmitting the command, noted as CID (Command index, the above-mentioned unique identifier), for recording the current command is the first command transmitted. When the receiving end replies the status of the command, the CID is also returned to the sending end. After the sending end receives the returned CID, it indicates that the command corresponding to the CID is correctly processed. The resources of the command corresponding to the CID can be released. In this way, a specified number of commands can be continuously transmitted, for example, 5 commands can be continuously transmitted to the receiving end. When processing the continuous commands, the receiving end does not need to reply the status after processing each command, but only needs to reply the status of the last command after processing the 5 commands. If the receiving end fails when processing a command in the middle, for example, when processing the third command, it needs to reply the status of the third command to the sending end. After receiving the status, the sending end can judge the CID in the status and the result of the status is success or failure. For example, if the CID is the CID of the last command and the result is success, it can prove that the 5 continuous commands are all correctly processed. If the result of the status is failure, the CID is checked, for example, the CID is 3, which indicates that the processing fails from the third command. The sending end will start retransmission from the third command next time and continuously transmit 5 commands to the receiving end from the third command.

[0061] In the embodiment, a command to be transmitted is acquired, and a transmission sequence is determined; a unique identifier is added to each of the commands according to the transmission sequence to obtain target commands, and each of the target commands is sent to a receiving end, so that the receiving end processes the target commands after acquiring the target commands and generates a return result; the return result sent by the receiving end is acquired, and the return result is parsed; if the return result is successful, a next transmission sequence to be transmitted is determined based on a transmission sequence corresponding to a last target command in the return result; a next target command to be transmitted is determined according to the next transmission sequence to be transmitted, and the next target command to be transmitted is sent to the receiving end, so that the receiving end processes the target command to be transmitted, until all the target commands are processed. The application transmits commands to the receiving end one by one, and each command carries a unique identifier. The receiving end processes the commands, and then generates a return result. The sending end receives the return result, and decides whether to retransmit a command or continue to send a next group of commands according to the return result, until all the commands are processed. The application can increase the performance of command transmission and improve the efficiency of command transmission.

The unique identifier is a CID, which is used to record the transmission order of the commands. The receiving end obtains the return result sent by the receiving end and parses the return result. If the return result is successful, then based on the unique identifier of the last target command in the target command group in the return result, a series of consecutive target commands starting from the next target command after the unique identifier of the target command form a next target command group and send it to the receiving end so that the receiving end can process the next target command group until all commands are processed. After parsing the returned result, the method further includes: if the returned result is a failure, then based on the unique identifier of the target command that failed to process in the returned result, a set number of consecutive target commands starting from that target command are formed into a retransmission target command group and resent to the receiving end.

2. The command transmission method according to claim 1, characterized in that, Before obtaining the command to be transmitted and determining the transmission order, the process also includes: Call the Internet Protocol address and perform network connectivity resolution on the Internet Protocol address. If the network is accessible, obtain the connection request, call the routing request, and parse the routing request based on the connection request. If the routing is normal, obtain the connection resource information. Invoke a connection command, and based on the connection command and the connection resource information, establish a direct remote memory access connection between the local machine and the receiving end.

3. The command transmission method according to claim 2, characterized in that, The invocation of the connection command, based on the connection command and utilizing the connection resource information, establishes a direct remote memory access connection between the local machine and the receiving end, including: A connection command is invoked and sent to the receiving end, so that the receiving end can respond to the connection command after receiving it. If the response is successful, information is generated to indicate that the remote memory direct access connection relationship between the local machine and the receiving end has been successfully established, and the information is sent to the local machine.

4. The command transmission method according to claim 2, characterized in that, The step of acquiring the command to be transmitted and determining the transmission order includes: Based on the remote memory direct access connection relationship, an IO queue is created using a multi-threaded approach, and a counting function is added to the IO queue; The command to be transmitted is obtained, the command is sent to the IO queue, and the transmission order of the command is determined according to the counting function.

5. The command transmission method according to claim 1, characterized in that, After sending a target command group consisting of a predetermined number of consecutive target commands to the receiving end, the method further includes: Record the sending time, determine whether the time interval between the current time and the sending time is greater than a preset response threshold, and if the time interval between the current time and the sending time is greater than the preset response threshold, then the sending of each target command is assumed to have failed, and the command resending operation is executed.

6. The command transmission method according to claim 1, characterized in that, The step of sending a target command group, consisting of a predetermined number of consecutive target commands, to the receiving end allows the receiving end to process the target command group and generate a return result, including: Each of the target command groups is sent to the receiving end so that the receiving end can process the target command group after obtaining it. If all the target commands in the target command group are processed successfully, a return result to be sent is generated. The transmission order corresponding to the last target command is determined, and the transmission order corresponding to the last target command is added to the return result to be sent to obtain the return result.

7. A command transmission device, characterized in that, include: The transmission order determination module is used to acquire the commands to be transmitted and determine the transmission order. The target command sending module is used to add a unique identifier to each of the commands according to the transmission order to obtain each target command, and to send a target command group consisting of a preset number of consecutive target commands to the receiving end, so that the receiving end can process the target command group after obtaining it and generate a return result. The unique identifier, CID, is used to record the transmission order of commands; The return result acquisition module is used to acquire the return result sent by the receiving end and parse the return result. If the return result is successful, then based on the unique identifier of the last target command in the target command group in the return result, a series of consecutive target commands starting from the next target command after the unique identifier of the target command form a next target command group and send it to the receiving end so that the receiving end can process the next target command group until all commands are processed. After parsing the returned result, the method further includes: if the returned result is a failure, then based on the unique identifier of the target command that failed to process in the returned result, a set number of consecutive target commands starting from that target command are formed into a retransmission target command group and resent to the receiving end.

8. An electronic device, characterized in that, include: Memory, used to store computer programs; A processor for executing the computer program to implement the command transmission method as described in any one of claims 1 to 6.

9. A computer-readable storage medium, characterized in that, Used to store computer programs; wherein, when the computer programs are executed by a processor, they implement the command transmission method as described in any one of claims 1 to 6.
