Description

Technical Field

[0001] The present application relates to the field of network chip technology, and in particular to a response message processing method and system. Background Art

[0002] RDMA (Remote Direct Memory Access) is a method of transferring data directly from memory to memory. It allows the network adapter to transfer data directly to the target computer's memory without the need for the target host's CPU to intervene in processing, which can significantly reduce network communication latency and improve data transfer efficiency. RoCEv2 (RDMA over Converged Ethernet version 2) is an Ethernet-based RDMA protocol and the second generation of RDMA technology. It combines Ethernet and RDMA to significantly enhance performance and flexibility. RoCEv2 bypasses the processing layer of traditional data transmission through direct memory access between systems, thereby reducing CPU involvement and reducing communication latency.

DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] like Figure 1 As shown, an embodiment of the present invention provides a response message processing system, including a message parsing module, a descriptor checking module, a request control module, a request information receiving module, an address reading module and a message construction module; The message parsing module is connected to the descriptor checking module and the message construction module respectively; The descriptor checking module is connected to the request control module and the request information receiving module respectively; The request information receiving module is connected to the request control module and the address reading module respectively; The message construction module is connected with the address reading module; A message parsing module, used for parsing the response message into response message data and a response message descriptor; A descriptor checking module, used for constructing and sending a corresponding response information descriptor according to the response message type, the queue pair status and the correctness of the response message descriptor; It should be noted that the message parsing module parses the response message according to the order in which the response messages are received to obtain the response message data and the response message descriptor; the message parsing module sends the response message descriptor to the descriptor checking module and sends the response message data to the message construction module.

[0019] In actual use, the response message descriptor includes most of the information of the response message, including the response message type, opcode, syndrome, qpn (queue pair number), psn (packet sequence number), msn (message sequence number) and len (message data length); the descriptor checking module is also used to determine the correctness of the response message descriptor, specifically to check whether the number, name and content of the fields contained in the response descriptor comply with the preset rules of the requesting end and the RoCEv2 protocol rules; the response message processing module stores and processes the response message descriptor in the order of receipt.

[0020] Preferably, the descriptor checking module is used to construct and send a corresponding response information descriptor according to the response message type, the queue pair state and the correctness of the response message descriptor in the queue pair, specifically: When the queue pair state is an abnormal state or there is error information in the response message descriptor, the constructed response message descriptor is a response message descriptor including the error information.

[0021] It should be noted that in RDMA technology, a queue pair is a basic communication unit, and each queue pair has its own sending queue and receiving queue for processing data transmission. Therefore, in the present invention, it is necessary to further process the response message under the premise that the queue pair is in a normal state to ensure the effectiveness of the response message processing; the abnormal state of the queue pair is that the queue pair cannot receive the response message or the queue pair has a valid bit pulled low.

[0022] Preferably, the descriptor checking module is used to construct and send a corresponding response information descriptor according to the response message type, the queue pair status and the correctness of the response message descriptor in the queue pair, specifically: When the queue pair state is an abnormal state or error information exists in the response message descriptor, the constructed response message descriptor is a response message descriptor including the error information.

[0023] It should be noted that when the queue pair status is abnormal or there is error information in the response message descriptor, a response information descriptor including the error information is constructed, and the error information is sent to the message construction module through the request control module, the request information receiving module and the address reading module, and the corresponding response message data is discarded.

[0024] Preferably, the descriptor checking module is used to construct and send a corresponding response information descriptor according to the response message type, the queue pair state and the correctness of the response message descriptor in the queue pair, specifically: When the response message is a non-read response message, sending a first response information descriptor to the request control module; When the response message is a read response message and is the first read response message that the request end expects to receive, construct a first response information descriptor and send it to the request control module, and construct a second response information descriptor and send it to the request information receiving module; When the response message is a read response message and is not the first or last read response message that the requesting end expects to receive, a second response information descriptor is constructed and sent to the request information receiving module.

[0025] It should be noted that the response message types include read response messages and non-read response messages; the read response message carries response message data, and the non-read response message does not contain response data; when the response message corresponding to the response message descriptor processed by the descriptor checking module is the first read response message that the requesting end expects to receive, a first response information descriptor is constructed and sent to the request control module, and the request information in the request message is obtained from the request control module, and at the same time, a second response information descriptor is constructed and sent to the request information receiving module; when the response message is a read response message and is not the first or last read response message that the requesting end expects to receive, a second response information descriptor is constructed and sent to the request information receiving module.

[0026] In the actual working process, when the queue pair state is normal, the descriptor checking module determines the type of the response message according to the response message descriptor. When the type of the response message is a non-read response message, a first response information descriptor is constructed to the request control module. At this time, the non-read response message is processed, and the descriptor checking module starts to process the next response message descriptor; when the queue pair state is normal, the descriptor checking module determines the type of the response message according to the response message descriptor. When the type of the response message is a read response message and it is the first read response message that the request end expects to receive, a first response information descriptor is constructed and sent to the request control module, and a second response information descriptor is constructed and sent to the request information receiving module; the content of the first response information descriptor is shown in Table 1 below: Table 1

[0027] The content of the second response information descriptor is shown in Table 2 below: Table 2

[0028] A request control module, used to store request information of the request message, construct and send a request information descriptor according to the response information descriptor and the request information; It should be noted that the content of the request information descriptor is shown in Table 3 below: Table 3

[0029] A request information receiving module, used for constructing and sending a request transfer descriptor according to the request information descriptor and the response information descriptor; It should be noted that the content of the request transfer descriptor is shown in Table 4 below: Table 4

[0030] An address reading module, used for constructing and sending a request information address descriptor according to the request transfer descriptor and the storage address of the message construction module; It should be noted that the content of the request information address descriptor is shown in Table 5 below: Table 5

[0031] It should be noted that when the request control module receives the response information descriptor including the error information, it constructs the sending request information descriptor including the error information; the request information receiving module receives the sending request information descriptor including the error information, and constructs the request transfer descriptor including the error information.

[0032] A message construction module, used for constructing and sending a request target message according to the request information address descriptor and the response message data, and sending a request target message sending completion signal to the descriptor checking module; The descriptor checking module is also used to send a completion signal according to the request target message, and construct and send a corresponding response information descriptor.

[0033] It should be noted that the message construction module receives the request information address descriptor. When the request message corresponding to the request information address descriptor is the last message that the requesting end expects to read, it constructs and sends the request target message, and at the same time sends a request target message sending completion signal to the descriptor checking module. The descriptor checking module constructs and sends the corresponding second response information descriptor to the request control module based on the request target message sending completion signal. At this time, the processing of a read response message is completed.

[0034] Preferably, the descriptor checking module processes one response message descriptor at a time; After the descriptor checking module receives the request target message sending completion signal and sends the first response information descriptor, the descriptor checking module starts to process the next response information descriptor in sequence.

[0035] In actual working process, the response message processing system of the present invention responds to messages one by one and processes one response message at a time; the descriptor checking module processes one response message descriptor at a time, and the processing order is FIFO (first in first out).

[0036] Preferably, the response message processing system further comprises: a queue pair state management module; The queue pair state management module is connected to the descriptor checking module; The queue pair status management module is used to monitor the queue pair status.

[0037] Preferably, the response message processing system further comprises: a bridging module; The bridge module is connected to the address reading module and the message construction module respectively; A bridge module, used for obtaining the storage address of the message construction module; The bridge module is also used to send the request target message to the corresponding request end address.

[0038] like Figure 2 As shown, a response message processing method is applied to a response message processing system, wherein the response message processing system includes a message parsing module, a descriptor checking module, a request control module, a request information receiving module, an address reading module and a message construction module, and the method includes: S1.
