Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a message processing method, apparatus, electronic device and storage medium. Background Technology

[0002] RoCE (RDMA over Converged Ethernet) is an Ethernet-based RDMA technology. There are two versions of RoCE, one of which is RoCEv2. RoCEv2 is based on the Ethernet User Datagram Protocol (UDP), and host devices supporting RoCEv2 provide four service modes: Reliable Connection (RC), Reliable Datagram (RD), Unreliable Connection (UC), and Unreliable Datagram (UD).

[0003] Currently, applications such as High Performance Computing (HPC) and Artificial Intelligence (AI) use the RoCEv2 protocol to achieve low-latency data transmission, and typically use RC mode to transmit RoCEv2 data streams.

[0004] In networks hosting HPC, AI, and other applications with "elephant streams," host devices using RC mode to transmit RoCEv2 data streams may experience issues such as unbalanced forwarding paths for RoCEv2 packets and poor scalability. To address this, a new service mode, Scalable Reliable Datagram (SRD), has been introduced in one application scenario. SRD mode does not preserve the packet order of RoCEv2 packets, sending them through as many network paths as possible to avoid path overload, thus offering better scalability.

[0005] However, adopting the SRD mode requires modifying the relevant drivers and kernel programs of the host device, and also requires re-adapting the SRD interface, which is inconvenient to operate and has poor applicability. Summary of the Invention

[0006] To overcome the problems existing in related technologies, this application provides a message processing method, apparatus, electronic device, and storage medium.

[0007] According to a first aspect of the embodiments of this application, a message processing method is provided, the method being applied to an HRD processing module in a host device, the method comprising:

[0008] The host device receives a first RoCEv2 data stream sent by the processing module corresponding to the service mode supported by the host device, wherein the service mode is RC mode, RD mode, UC mode or mode ;

[0009] The first RoCEv2 data stream is divided into multiple first sub-data streams, and based on the available ports on each first sub-data stream, the source ports used by multiple first RoCEv2 packets corresponding to each first sub-data stream are determined. Among them, the source ports used by multiple first RoCEv2 packets corresponding to a sub-data stream are the same, and the source ports used by multiple first RoCEv2 packets corresponding to different sub-data streams are different.

[0010] Multiple first RoCEv2 packets corresponding to each first sub-data stream are cached in the sub-data stream queue corresponding to the source port. For each sub-data stream queue, the first RoCEv2 packet is sent to the destination host device of the first RoCEv2 data stream in turn based on the five-tuple information of each first RoCEv2 packet in the sub-data stream queue.

[0011] According to a second aspect of the embodiments of this application, a message processing apparatus is provided, wherein the HRD processing module applied in a host device includes:

[0012] The receiving unit is configured to receive a first RoCEv2 data stream sent by the processing module corresponding to the service mode supported by the host device in the host device, wherein the service mode is RC mode, RD mode, UC mode or UD mode;

[0013] The determining unit is used to divide the first RoCEv2 data stream into multiple first sub-data streams, and based on its own available ports, determine the source ports used by multiple first RoCEv2 messages corresponding to each first sub-data stream, wherein multiple first RoCEv2 messages corresponding to one sub-data stream use the same source port, and multiple first RoCEv2 messages corresponding to different sub-data streams use different source ports.

[0014] The buffer sending unit is used to buffer multiple first RoCEv2 packets corresponding to each first sub-data stream into the sub-data stream queue corresponding to the source port, and for each sub-data stream queue, send the first RoCEv2 packet to the destination host device of the first RoCEv2 data stream in turn based on the five-tuple information of each first RoCEv2 packet in the sub-data stream queue.

[0015] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0016] In this embodiment, an HRD processing module is added to the host device. This module is responsible for processing RoCEv2 data streams from processing modules corresponding to RC mode, RD mode, UC mode, or UD mode within the host device. The RoCEv2 data stream is divided into multiple sub-data streams, and the RoCEv2 packets corresponding to these sub-data streams are distributed across different paths for transmission. This packet processing method does not require interface adaptation and can achieve reliable but not ordered packet transmission. Furthermore, it effectively utilizes path resources, is convenient to operate, and has good applicability.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0025] The embodiments of this application will now be described in detail.

[0026] This application provides a message processing method, which is applied to a high-performance reliable datagram (HRD) processing module in a host device, such as... Figure 1 As shown, the method may include the following steps:

[0027] S11. Receive the first RoCEv2 data stream sent by the processing module corresponding to the service mode supported by the host device in the host device.

[0028] In this step, the service mode mentioned above is RC mode, RD mode, UC mode, or UD mode.

[0029] It should be noted that the specific acquisition process of the first RoCEv2 data stream on the processing module side corresponding to the service mode supported by the host device is existing technology and will not be described in detail here.

[0030] S12. Divide the first RoCEv2 data stream into multiple first sub-data streams, and determine the source port used by multiple first RoCEv2 messages corresponding to each first sub-data stream based on the available ports on itself.

[0031] In this step, multiple first RoCEv2 messages corresponding to a sub-data stream use the same source port, and multiple first RoCEv2 messages corresponding to different sub-data streams use different source ports.

[0032] S13. Cache multiple first RoCEv2 packets corresponding to each first sub-data stream into the sub-data stream queue corresponding to the source port, and for each sub-data stream queue, send the first RoCEv2 packet to the destination host device of the first RoCEv2 data stream in turn based on the five-tuple information of each first RoCEv2 packet in the sub-data stream queue.

[0033] Specifically, in step S12 above, the HRD processing module can divide the first RoCEv2 data stream into multiple first sub-data streams in various ways. For example, the HRD processing module can divide the first RoCEv2 data stream into multiple first sub-data streams based on the configured partitioning rules. The specific number of first sub-data streams and the number of RoCEv2 messages corresponding to each first sub-data stream can be configured in the partitioning rules.

[0034] Additionally, in this step, the HRD processing module can determine the source port used by multiple first RoCEv2 messages corresponding to each first sub-data stream in the following way:

[0035] For each first sub-data stream, randomly select an available port from its available ports, and use the selected available port as the source port for multiple first RoCEv2 messages corresponding to that first sub-data stream.

[0036] Of course, the HRD processing module can also determine the source port used by multiple first RoCEv2 messages corresponding to each first sub-data stream in other ways, which will not be listed here.

[0037] Specifically, in step S13 above, for any RoCEv2 packet in any sub-data stream queue, the HRD processing module can perform a hash operation on the five-tuple information of the first RoCEv2 packet according to a preset hash algorithm to obtain a hash result; and find the corresponding output port of the calculated hash result in the correspondence between each hash result and each output port stored locally, and send the first RoCEv2 packet to the corresponding next-hop device through the output port, so that the next-hop device can continue to forward the first RoCEv2 packet to the destination host device.

[0038] Furthermore, in this embodiment of the application, the HRD processing module may also perform the following operations:

[0039] After sending the first RoCEv2 message to the destination host device, start the timeout timer;

[0040] If an acknowledgment message for the first RoCEv2 message is received from the destination host device within the timeout period of the timeout timer, then the timeout timer is turned off.

[0041] When the acknowledgment message carries the first timestamp of when the HRD processing module sent the first RoCEv2 message, the RTT value of the path for transmitting the first RoCEv2 message is calculated based on the first timestamp and the second timestamp of when the acknowledgment message is received, and the calculated RTT value is assigned as the RTT value corresponding to the sub-data stream queue.

[0042] If the first RoCEv2 message is not the last first RoCEv2 message in the sub-data stream queue, and the calculated RTT value is greater than a first preset threshold, then the unsent first RoCEv2 message in the sub-data stream queue is cached in a sub-data stream queue whose corresponding RTT value is not greater than a second preset threshold, where the first preset threshold is greater than the second preset threshold; or,

[0043] When the confirmation message carries the number of the first RoCEv2 message sent by the HRD processing module of the destination host device cache, if the number of messages is not greater than the set number, the current message sending rate is maintained; if the number of messages is greater than the set number, the current message sending rate is reduced according to the preset rules.

[0044] In this operation process, the HRD processing module will subtract the second timestamp from the first timestamp to obtain the RTT value of the path through which the first RoCEv2 message was transmitted.

[0045] For example, suppose the HRD processing module receives RoCEv2 data stream 1 sent by the processing module corresponding to the RC mode in the host device, and RoCEv2 data stream 1 is divided into 3 sub-data streams, namely sub-data stream 1, sub-data stream 2 and sub-data stream 3; and each sub-data stream corresponds to 5 RoCEv2 messages.

[0046] Suppose that after the HRD processing module sends the first RoCEv2 message corresponding to sub-data stream 1 to the destination host device, it starts a timeout timer. Within the timeout period, it receives an acknowledgment message for the RoCEv2 message from the destination host device. At this time, the HRD processing module stops the timeout timer and finds that the acknowledgment message carries the first timestamp when the HRD processing module sent the RoCEv2 message. In this case, the HRD processing module subtracts the first timestamp from the second timestamp when it receives the acknowledgment message, uses the result as the RTT value of the path for transmitting the first RoCEv2 message, and assigns the result as the RTT value corresponding to the sub-data stream queue of sub-data stream 1.

[0047] If the result of the operation is greater than the first set threshold, and if the RTT value of the sub-data stream queue corresponding to the current sub-data stream 1 is less than the second set threshold, then the HRD processing module will cache the four unsent first RoCEv2 messages in the sub-data stream queue of the first RoCEv2 message corresponding to the cached sub-data stream 3 into the sub-data stream queue corresponding to the sub-data stream 1.

[0048] It should be noted that for any first RoCEv2 message in any sub-data stream queue, once the corresponding acknowledgment message is received, the HRD processing module will calculate the corresponding RTT value and assign it as the RTT value for that sub-data stream queue. Therefore, the RTT value for that sub-data stream queue is dynamically changing.

[0049] It should be further noted that in this operation process, initially, the HRD processing module sends the first RoCEv2 message in the sub-data stream queue according to the set sending rate.

[0050] When the HRD processing module reduces the current message sending rate, the preset rules can be to reduce the current message sending rate by a set ratio or by a set value.

[0051] In addition, for the HRD processing module, if it does not receive an acknowledgment message for the first RoCEv2 message from the destination host device within the timeout period of the timeout timer, it will resend the first RoCEv2 message to the destination host device and restart the timeout timer until it receives an acknowledgment message for the first RoCEv2 message from the destination host device.

[0052] It should be noted that, in the embodiments of this application, the timeout duration, the first set threshold, the second set threshold, and the set quantity can all be set by the administrator according to network requirements and configured in advance on the HRD processing module.

[0053] Furthermore, in this embodiment of the application, the HRD processing module may also perform the following operations:

[0054] When a second RoCEv2 message corresponding to the target sub-data stream of the second RoCEv2 data stream sent by the destination host device is received, if it is determined from the service mode carried in the second RoCEv2 message that the second RoCEv2 message is a message that does not need to be ordered, then the second RoCEv2 message is sent to the processing module corresponding to the service mode carried in the second RoCEv2 message for processing, and an acknowledgment message is sent to the destination host device to indicate that the second RoCEv2 message has been successfully received.

[0055] If the second RoCEv2 message is determined to be a message requiring order preservation based on the service mode carried in the second RoCEv2 message, then the second RoCEv2 message is sent to the processing module corresponding to the service mode carried in the second RoCEv2 message for processing, or...

[0056] When the number of packets in the cache queue corresponding to the service mode carried in the second RoCEv2 packet has not reached the preset number, the second RoCEv2 packet is cached in the cache queue. When the number of packets in the cache queue reaches the preset number, the second RoCEv2 packets in the cache queue are sorted in ascending order of packet sequence number, and each sorted second RoCEv2 packet is sent to the corresponding processing module for processing in turn.

[0057] By executing the above operation process, the HRD processing module can process RoCEv2 data streams from the processing modules corresponding to RC mode, RD mode, UC mode, or UD mode in the host device, thus improving applicability.

[0058] Specifically, in this operation process, the HRD processing module can determine whether the second RoCEv2 message is a message that needs to be ordered by sequence in the following way:

[0059] If the service mode carried in the second RoCEv2 message is RC mode or RD mode, then the second RoCEv2 message is determined to be a message that needs to be ordered.

[0060] If the service mode carried in the second RoCEv2 message is UC mode or UD mode, then the second RoCEv2 message is determined to be a message that does not require order preservation.

[0061] As can be seen from the above technical solutions, in this embodiment, an HRD processing module is added to the host device to process RoCEv2 data streams from the processing modules corresponding to RC mode, RD mode, UC mode, or UD mode in the host device. The RoCEv2 data stream is divided into multiple sub-data streams, and the RoCEv2 packets corresponding to the sub-data streams are distributed to different paths for transmission. This packet processing method does not require interface adaptation and can achieve reliable but not ordered packet transmission. Furthermore, it effectively utilizes path resources, is convenient to operate, and has good applicability.

[0072] If the first RoCEv2 message is not the last first RoCEv2 message in the sub-data stream queue, and the calculated RTT value is greater than a first preset threshold, then the unsent first RoCEv2 message in the sub-data stream queue is cached in a sub-data stream queue whose corresponding RTT value is not greater than a second preset threshold, wherein the first preset threshold is greater than the second preset threshold; or...

[0073] When the confirmation message carries the number of first RoCEv2 messages sent by the HRD processing module cached by the destination host device, if the number of messages is not greater than a set number, the current message sending rate is maintained; if the number of messages is greater than the set number, the current message sending rate is reduced according to a preset rule.

[0074] Preferably, the buffer sending unit 23 is further configured to:

[0075] If no acknowledgment message for the first RoCEv2 message is received from the destination host device within the timeout period of the timeout timer, the first RoCEv2 message is resent to the destination host device, and the timeout timer is restarted until an acknowledgment message for the first RoCEv2 message is received from the destination host device.

[0078] If the service mode carried in the second RoCEv2 message indicates that the second RoCEv2 message is a message requiring order preservation, then the second RoCEv2 message is sent to the processing module corresponding to the service mode carried in the second RoCEv2 message for processing, or...

[0079] When the number of packets in the cache queue corresponding to the service mode carried in the second RoCEv2 packet has not reached the preset number, the second RoCEv2 packet is cached in the cache queue.

When the acknowledgment message carries the first timestamp of when the HRD processing module sent the first RoCEv2 message, if the first RoCEv2 message is not the last first RoCEv2 message in the sub-data stream queue, then based on the first timestamp and the second timestamp of when the acknowledgment message is received, the RTT value of the path that transmitted the first RoCEv2 message is calculated, and the calculated RTT value is assigned as the RTT value corresponding to the sub-data stream queue; If the calculated RTT value is greater than a first preset threshold, then the first RoCEv2 packet that has not been sent in the sub-data stream queue is buffered into a sub-data stream queue whose corresponding RTT value is not greater than a second preset threshold, wherein the first preset threshold is greater than the second preset threshold; or... When the confirmation message carries the number of first RoCEv2 messages sent by the HRD processing module cached by the destination host device, if the number of messages is not greater than a set number, the current message sending rate is maintained; if the number of messages is greater than the set number, the current message sending rate is reduced according to a preset rule.

7. The apparatus according to claim 6, characterized in that, The buffer sending unit is further configured to: If no acknowledgment message for the first RoCEv2 message is received from the destination host device within the timeout period of the timeout timer, the first RoCEv2 message is resent to the destination host device, and the timeout timer is restarted until an acknowledgment message for the first RoCEv2 message is received from the destination host device.

8. The apparatus according to claim 6, characterized in that, The device further includes: The processing unit is configured to, upon receiving a second RoCEv2 message corresponding to a target sub-data stream of a second RoCEv2 data stream sent by the destination host device, if it is determined from the service mode carried in the second RoCEv2 message that the second RoCEv2 message is a message that does not require order preservation, send the second RoCEv2 message to the processing module corresponding to the service mode carried in the second RoCEv2 message for processing, and send an acknowledgment message to the destination host device to indicate that the second RoCEv2 message has been successfully received; If the service mode carried in the second RoCEv2 message indicates that the second RoCEv2 message is a message requiring order preservation, then the second RoCEv2 message is sent to the processing module corresponding to the service mode carried in the second RoCEv2 message for processing, or... When the number of packets in the cache queue corresponding to the service mode carried in the second RoCEv2 packet has not reached the preset number, the second RoCEv2 packet is cached in the cache queue. When the number of packets in the cache queue reaches the preset number, the second RoCEv2 packets in the cache queue are sorted in ascending order of packet sequence number, and each sorted second RoCEv2 packet is sent to the corresponding processing module for processing in turn.
