Description

Technical Field

[0001] The present invention relates to the field of NCSI, and in particular, to a method, system, device, and storage medium for processing asynchronous event packets. Background Art

[0002] NCSI (Network Controller Sideband Interface), as an industry standard for sideband interface network controllers that support out-of-band management of servers defined by the Distributed Management Task Force (DMTF), is supported by devices from major network card manufacturers (such as Broadcom, etc.). However, currently, the support for AEN asynchronous event packets is still not perfect. An AEN asynchronous event packet is an announcement data packet actively sent by a network controller to a management controller when certain state changes occur and affect the normal operation of its interface. These events include: link state changes, loading and unloading of operating system drivers, chip reset, etc. An AEN packet is a type of NCSI packet that operates outside the NCSI request-response mechanism. That is to say, an AEN packet is neither an NCSI request nor a response to any NCSI request. An AEN packet has no response, and even if an AEN packet is lost during transmission, the management controller has no way of knowing. Summary of the Invention

[0064] To make the purpose, technical solutions, and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail with reference to specific embodiments and the accompanying drawings.

[0065] It should be noted that in the embodiments of the present invention, all expressions using "first" and "second" are for distinguishing two entities or parameters with the same name but different identities. It can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present invention. This will not be elaborated one by one in the subsequent embodiments.

[0066] In an embodiment of the present invention, AEN is Asynchronous Event Notification, i.e., asynchronous event notification.

[0067] According to one aspect of the present invention, an embodiment of the present invention provides a method for processing asynchronous event packets, as Figure 1 shown, which may include the steps:

[0068] S1, in response to receiving an asynchronous event packet, verifying the checksum recorded in the first preset field in the asynchronous event packet;

[0069] S2, in response to the verification of the checksum passing, obtaining the type of the asynchronous event packet recorded in the second preset field in the asynchronous event packet;

[0070] S3, obtaining the current network status and comparing it with the type of the asynchronous event packet;

[0071] S4, in response to the current network status matching the status corresponding to the type of the asynchronous event packet, putting the currently received asynchronous event packet into the receiving list.

[0072] The solution proposed by the present invention can better grasp the health status of the current network and the network changes of the corresponding link through the processing of asynchronous event packets, and can generate corresponding detection reports. According to the problems in the detection statistical report, the network link can be optimized targeted.

[0073] In some embodiments, it further includes:

[0074] Constructing the asynchronous event packet, wherein the IID field of the asynchronous event packet is set to an increasing value to uniquely determine an asynchronous event packet, the first byte of the 3-byte reserved field in the NCSI payload is used as the third preset field for recording the sequence number, and the second and third bytes of the 3-byte reserved field in the NCSI payload are used as the first preset field for recording the checksum.

[0075] Specifically, as Figure 2 shown, the current AEN Ethernet frame protocol stipulates that the IID is a fixed value, 0x0, while this application modifies it to an increasing value. Through this field, the network controller can uniquely determine an AEN asynchronous event notification packet. Then, it is defined that the first byte of the 3-byte reserved field in the NCSI payload of the AEN packet ( Figure 2In the 16 - 19 bytes, bits 08 - 15) is the AEN sequence field. It is agreed that 16 AEN packets starting from 0x00 and ending at 0x0F form a complete sequence. This sequence is used in the network controller to collect and record the reception status of AEN asynchronous event notification packets; define the 2nd and 3rd bytes of the 3 - byte reserved field in the NCSI payload of the AEN packet as the checksum ( Figure 2 In the 16 - 19 bytes, bits 16 - 31), the management controller can use the checksum part to verify the AEN packet.

[0076] In some embodiments, it further includes:

[0077] In response to the current network state not matching the state corresponding to the type of the asynchronous event packet, put the currently received asynchronous event packet into the error list.

[0078] In some embodiments, it further includes:

[0079] Obtain the sequence number of the asynchronous event packet recorded in the third preset field of the asynchronous event packet;

[0080] Judge whether the sequence number of the currently received asynchronous event packet and the sequence numbers of the asynchronous event packets in the reception list are consecutive;

[0081] In response to non - consecutive, determine that there is an asynchronous event packet loss and put the corresponding sequence number into the error list.

[0082] Specifically, based on the existing NCSI protocol, the AEN asynchronous event notification packet is a type of NCSI packet that operates outside the NCSI request-response mechanism. That is to say, the AEN packet is neither an NCSI request nor a response to any NCSI request. The AEN packet has no response. Even if an AEN packet is lost during transmission, the network controller has no way of knowing. Based on this situation, combined with the improved AEN Ethernet frame format in S11, we define the following processing mechanism based on the BMC system: 1) Create a thread ListenAEN under the IPMIMain process in the BMC system to receive AEN asynchronous event notification packets; 2) After receiving the AEN asynchronous event notification packet, first verify the checksum in the reserved field. If the verification fails, record the IID of the packet and the AEN type in the error packet list, and mark the error reason as verification failure and record it; 3) If the verification in 2) passes, then verify the sequence field of the packet. The verification rules are as follows: a) Let the sequence number in the current sequence field be i. If i-1 is not in the receiving list, then verify forward to find the sequence number closest to i, denoted as j, and record the IIDs and AEN types corresponding to the sequence numbers from j+1 to i-1 in the error list, and mark the error reason as packet loss and record it. At the same time, record i in the receiving list for subsequent packet verification; b) According to the AEN type of the AEN asynchronous event notification packet, obtain the current network status according to the NCSI protocol and compare it. If the current network status does not match the status corresponding to the AEN packet type, record the IID and AEN type in the error list, and mark the error reason as AEN event failure; 3) The ListenAEN thread regularly exports an AEN monitoring report according to the time specified by the timer, based on the receiving list and the error list, counts the number of failed AEN packets, the failure reasons, and the corresponding AEN types, and generates a statistical result for feedback; 4) According to the generated statistical result, further adjust or optimize the network card or network link.

[0083] In some embodiments, the solution proposed by the present invention can be applied to the BMC system, but is not limited to the BMC system. All systems that act as management controllers in the NCSI protocol model can apply this processing mechanism.

[0084] The solution proposed by the present invention can better grasp the current network health status and the network changes of the corresponding link through the processing of asynchronous event packets, and can generate corresponding detection reports. According to the problems in the detection statistical report, the network link can be optimized purposefully.
