Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method and apparatus for packet processing, an electronic device, and a storage medium. Background Art

[0002] RoCE (RDMA over Converged Ethernet), that is, RDMA technology based on Ethernet. RoCE has two versions, one of which is RoCEv2. RoCEv2 is based on the User Datagram Protocol (UDP) protocol of Ethernet, and the host device supporting the RoCEv2 protocol provides four service modes, namely, Reliable Connection (RC) mode, Reliable Datagram (RD) mode, Unreliable Connection (UC) mode, and Unreliable Datagram (UD) mode.

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

[0004] In the case of elephant flows existing in the network where applications such as HPC and AI are located, when the host device uses the RC mode to transmit RoCEv2 data streams, there will be problems such as unbalanced forwarding paths and poor scalability of the RoCEv2 packets corresponding to the RoCEv2 data streams. In one application scenario, a new service mode, namely, Scalable Reliable Datagram (SRD) mode, is added to the host device. The SRD mode does not retain the packet order of RoCEv2 packets and sends RoCEv2 packets through as many network paths as possible to avoid path overload, and has good scalability.

[0005] However, adopting the SRD mode requires modifying relevant driver programs, kernel programs, etc. 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

[0010] Caching multiple first RoCEv2 packets corresponding to each first sub-data stream into a sub-data stream queue corresponding to the corresponding source port, and for each sub-data stream queue, sequentially sending the first RoCEv2 packet to the destination host device of the first RoCEv2 data stream based on the five-tuple information of each first RoCEv2 packet in the sub-data stream queue.

[0025] Next, the embodiments of this application will be described in detail.

[0026] The embodiment of 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 above service mode is the RC mode, the RD mode, the UC mode or the UD mode.

[0029] It should be noted that the specific process of obtaining the first RoCEv2 data stream on the processing module side corresponding to the service mode supported by the host device is a prior art and will not be elaborated herein.

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

[0031] In this step, the source ports used by multiple first RoCEv2 messages corresponding to one sub-data stream are the same, and the source ports used by multiple first RoCEv2 messages corresponding to different sub-data streams are different.

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

[0033] Specifically, in the above step S12, 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 division rules. The specific number of the first sub-data streams and the number of RoCEv2 packets corresponding to each first sub-data stream can be configured in the division rules.

[0034] In addition, in this step, the HRD processing module can determine the source ports used by multiple first RoCEv2 packets corresponding to each first sub-data stream in the following ways:

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

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

[0037] Specifically, in the above step S13, 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 based on the corresponding relationship between each hash result stored locally and each output port, find the output port corresponding to the calculated hash result, and send the first RoCEv2 packet to the corresponding next-hop device through this output port, so that the next-hop device can continue to forward the first RoCEv2 packet to the destination host device.

[0038] Furthermore, in the embodiments of the present application, the HRD processing module can also perform the following operations:

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

[0040] If an acknowledgment packet sent by the destination host device for the first RoCEv2 packet is received within the timeout duration of the timeout timer, close the timeout timer;

[0041] When the acknowledgment packet carries the first timestamp when the HRD processing module sends the first RoCEv2 packet, calculate the RTT value of the path for transmitting the first RoCEv2 packet based on the first timestamp and the second timestamp when the acknowledgment packet is received, and assign the calculated RTT value to the RTT value corresponding to the sub-data stream queue;

[0042] If the first RoCEv2 packet is not the last first RoCEv2 packet in the sub-data flow queue and the calculated RTT value is greater than the first set threshold, then the unsent first RoCEv2 packets in the sub-data flow queue are cached into a sub-data flow queue corresponding to an RTT value not greater than the second set threshold, where the first set threshold is greater than the second set threshold; or,

[0043] When the number of first RoCEv2 packets sent by the HRD processing module cached in the destination host device is carried in the acknowledgment packet, if the number of packets is not greater than the set number, then the current packet sending rate is maintained; if the number of packets is greater than the set number, then the current packet sending rate is reduced according to a preset rule.

[0044] In this operation process, the HRD processing module will perform a subtraction operation on the second timestamp and the first timestamp to obtain the RTT value of the path for transmitting the first RoCEv2 packet.

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

[0046] Also assume that after the HRD processing module sends the first RoCEv2 packet corresponding to sub-data flow 1 to the destination host device, it starts a timeout timer, and, within the timeout duration of the timeout timer, it receives an acknowledgment packet sent by the destination host device for this RoCEv2 packet. At this time, the HRD processing module closes the timeout timer and finds that the acknowledgment packet carries the first timestamp when the HRD processing module sends this RoCEv2 packet. In this case, the HRD processing module performs a subtraction operation on the second timestamp when it receives the acknowledgment packet and the first timestamp, takes the operation result as the RTT value of the path for transmitting the first RoCEv2 packet, and assigns the operation result to the RTT value corresponding to the sub-data flow queue corresponding to sub-data flow 1.

[0047] Assume that the operation result is greater than the first set threshold, and, assume that the RTT value corresponding to the current sub-data flow queue of sub-data flow 1 is less than the second set threshold. Then, the HRD processing module will cache the 4 unsent first RoCEv2 packets in the sub-data flow queue caching the first RoCEv2 packets corresponding to sub-data flow 3 into the sub-data flow queue corresponding to sub-data flow 1.

[0048] It should be noted that for any first RoCEv2 packet in any sub-data stream queue, once the corresponding acknowledgment packet is received, the HRD processing module calculates the corresponding RTT value and assigns it as the RTT value corresponding to the sub-data stream queue. Therefore, the RTT value corresponding to the sub-data stream queue changes dynamically.

[0049] Further, it should be noted that in this operation process, initially, the HRD processing module sends the first RoCEv2 packets in the sub-data stream queue at the set sending rate.

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

[0051] In addition, for the HRD processing module, if the acknowledgment packet for the first RoCEv2 packet sent by the destination host device is not received within the timeout duration of the timeout timer, the first RoCEv2 packet is resent to the destination host device, and the timeout timer is restarted until the acknowledgment packet for the first RoCEv2 packet sent by the destination host device is received.

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

[0053] Furthermore, in the embodiments of the present application, the HRD processing module can also perform the following operations:

[0054] When receiving a second RoCEv2 packet corresponding to the target sub-data stream of the second RoCEv2 data stream sent by the destination host device, if it is determined according to the service mode carried in the second RoCEv2 packet that the second RoCEv2 packet is a packet that does not require in-sequence delivery, the second RoCEv2 packet is sent to the processing module corresponding to the service mode carried in the second RoCEv2 packet for processing, and an acknowledgment packet indicating that the second RoCEv2 packet has been successfully received is sent to the destination host device;

[0055] If it is determined according to the service mode carried in the second RoCEv2 packet that the second RoCEv2 packet is a packet that requires in-sequence delivery, the second RoCEv2 packet is sent to the processing module corresponding to the service mode carried in the second RoCEv2 packet for processing, or,

[0056] When the number of packets in the cache queue corresponding to the service mode carried in the second RoCEv2 packet does not reach the preset number, cache the second RoCEv2 packet into the cache queue. When the number of packets in the cache queue reaches the preset number, sort the second RoCEv2 packets in the cache queue in ascending order of packet sequence numbers, and sequentially send each sorted second RoCEv2 packet to the corresponding processing module for processing.

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

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

[0059] If the service mode carried in the second RoCEv2 packet is the RC mode or the RD mode, determine that the second RoCEv2 packet is a packet that needs to be in-sequence;

[0060] If the service mode carried in the second RoCEv2 packet is the UC mode or the UD mode, determine that the second RoCEv2 packet is a packet that does not need to be in-sequence.

[0061] It can be seen from the above technical solutions that in the embodiment of the present application, an HRD processing module is added in the host device, which is responsible for processing the RoCEv2 data stream from the processing module corresponding to the RC mode, the processing module corresponding to the RD mode, the processing module corresponding to the UC mode, or the processing module corresponding to the UD mode in the host device, dividing the RoCEv2 data stream into multiple sub-data streams, and dispersing the RoCEv2 packets corresponding to the sub-data streams to different paths for transmission. This packet processing method can achieve reliable but not in-sequence packet transmission without interface adaptation, and can also effectively utilize path resources, is convenient to operate, and has good applicability.

[0072] If the first RoCEv2 packet is not the last first RoCEv2 packet in the sub-data stream queue and the calculated RTT value is greater than a first set threshold, cache the first RoCEv2 packets not sent in the sub-data stream queue into a sub-data stream queue whose corresponding RTT value is not greater than a second set threshold, where the first set threshold is greater than the second set threshold; or,
