Description

TECHNICAL FIELD

[0001] The present application relates to the field of computer, and more particularly to a method, device, system, equipment and readable medium for processing message packet loss. BACKGROUND

[0002] A message is information representing a certain state occurring in the process of program execution, and events occurring in the system can be transmitted through the message. The message is triggered by an event, and a message corresponding to the event is generated when the event is reached. The message can be classified into different types according to the importance, such as normal working messages and messages in abnormal situations. Usually, a system contains many components, and these components generate a large amount of message data. When a large number of events occur in the system at a certain moment, a large amount of messages are generated, and the bandwidth of the generated messages can be greater than the output bandwidth of the messages. This state can cause message sending to be blocked, which can affect the performance of the system. The message content that does not affect the normal work of the system can be actively discarded as needed, such as log information generated in the normal work of the system and barrage information in the video stream.

[0003] In the process of message transmission, when message data is waiting to be sent in the buffer queue, a queue management method of "discarding message data when the buffer queue is full" is adopted. That is, the buffer queue continuously receives the message data packets sent by the sending end. When the output rate of the buffer queue is less than the input rate, the data packets cached in the buffer queue will be more and more, and the cache space of the buffer queue will also be less and less, until the buffer queue has no remaining cache space. At this time, if the sending end has message data packets to send to the cache queue, the buffer queue will discard all the data packets sent by the sending end at this time. However, this packet loss method cannot know whether packet loss occurs between the two received messages and the number of packet loss. SUMMARY

[0004] Therefore, the purpose of the embodiments of the present application is to provide a method, device, system, equipment and readable medium for processing message packet loss. By using the technical solution of the present application, resource waste caused by multiple sending of the same packet loss information can be avoided, the occurrence of packet loss and the number of packet loss in the process of message transmission can be accurately recorded, and the stability of the server can be enhanced.

[0005] In order to achieve the above purpose, one aspect of an embodiment of the present application provides a method for processing message packet loss, comprising the following steps:

[0016] In response to a situation where the available memory space is less than the sum of the message size of the new message and the size of the packet loss information, it is determined whether the message type of the new message is consistent with the packet loss type of the packet loss information;

[0018] According to one embodiment of the present invention, it further includes:

[0019] If the message type of a new message is inconsistent with the packet loss type of the packet loss information, determine whether the available storage space is greater than or equal to the size of the packet loss information.

[0020] In response to a situation where the available memory space is greater than or equal to the size of the lost packet information, the lost packet information is written into the memory, and the lost packet information of the new message is recorded as the new lost packet information to be sent.

[0055] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0056] Based on the above objectives, a first aspect of the embodiments of the present invention provides an embodiment of a method for handling message packet loss. Figure 1 The diagram shown is a schematic flowchart of the method.

[0057] like Figure 1 As shown, the method may include the following steps:

[0058] S1 responds to the packet loss device receiving a new message by determining whether there is any packet loss information to be sent within the device. In addition to the message content, two signals, `size` and `type`, are defined within the message information. `size` represents the message size, and `type` represents the message type. The format of the packet loss information is also defined, including a packet loss information flag, a packet loss type, a packet loss count, and a multi-type packet loss flag. The packet loss information flag indicates that the message is packet loss information, the packet loss type records the current type of packet loss, the packet loss count records the number of packets lost under the current packet loss type, and the multi-type packet loss flag indicates that multiple different types of packet loss have occurred.

[0059] S2 responds to the fact that there is no lost packet information to be sent within the packet loss device, and determines whether the available space in the memory is greater than the message size of the new message. When a new message is received, if there is no lost packet information to be sent within the device, it determines whether the available space in the memory is greater than or equal to the message size of the new message.

[0060] S3 responds when the available memory space is less than the message size of the new message, discarding the new message and writing its packet loss information into memory. If the available memory space is less than the message size of the new message, meaning the memory can no longer store the message, then the new message is discarded, and its packet loss information is directly written into memory. In this way, the message receiver can know that a packet loss event occurred during message transmission and can determine the type and number of packets lost from the packet loss information.

[0061] By using the technical solution of the present invention, resource waste caused by sending the same packet loss information multiple times can be avoided, packet loss can be accurately recorded during message transmission and the number of packets lost, thereby enhancing server stability.

[0062] In a preferred embodiment of the present invention, it further includes:

[0063] If the available memory space is greater than the message size of the new message, the new message is written to memory. If the available memory space is greater than the message size of the new message, meaning the memory can store the new message, then the new message is written to memory directly.

[0064] In a preferred embodiment of the present invention, it further includes:

[0065] In response to packet loss information waiting to be sent inside the packet loss device, determine whether the available space in the memory is greater than or equal to the sum of the message size of the new message and the size of the lost packet information;

[0066] In response to the condition that the available memory space is greater than or equal to the sum of the size of the new message and the size of the lost packet information, the lost packet information and the new message are written into memory. If the packet loss device already has lost packet information to be sent, i.e., both lost packet information and the new message exist simultaneously, it is necessary to determine whether the available memory space is greater than or equal to the sum of the size of the new message and the size of the lost packet information. If the available memory space is greater than or equal to the sum of the size of the new message and the size of the lost packet information, i.e., the memory can store both the new message and the lost packet information simultaneously, then the lost packet information is written into memory first, and then the new message is written into memory.

[0067] In a preferred embodiment of the present invention, writing packet loss information and new messages into the memory includes:

[0068] Write the packet loss information into the memory;

[0069] In response to packet loss information being written to memory, a new message is written to memory.

[0070] In a preferred embodiment of the present invention, it further includes:

[0071] In response to packet loss information waiting to be sent inside the packet loss device, determine whether the available space in the memory is greater than or equal to the sum of the message size of the new message and the size of the lost packet information;

[0072] In response to a situation where the available memory space is less than the sum of the message size of the new message and the size of the packet loss information, it is determined whether the message type of the new message is consistent with the packet loss type of the packet loss information;

[0073] If the message type of the new message matches the packet loss type of the packet loss information, the new message is discarded, and the packet loss count in the packet loss information is incremented by 1 and written to memory. If the available memory space is less than the sum of the message size of the new message and the size of the packet loss information, meaning the memory cannot store the new message and the packet loss information simultaneously, then it is first determined whether the types of the new message and the packet loss information are the same. If they are the same, the new message is discarded, the packet loss count in the original packet loss information is incremented by 1, and the packet loss information is written to memory. In this case, the packet loss information indicates that two packet loss events of the same type have occurred.

[0074] In a preferred embodiment of the present invention, it further includes:

[0075] If the message type of a new message is inconsistent with the packet loss type of the packet loss information, determine whether the available storage space is greater than or equal to the size of the packet loss information.

[0076] In response to a situation where the available memory space is greater than or equal to the size of the lost packet information, the lost packet information is written into memory, and the lost packet information of the new message is recorded as the new lost packet information to be sent. If the message type of the new message is inconsistent with the lost packet type of the lost packet information, it is necessary to determine whether the available memory space is greater than or equal to the size of the lost packet information. If it is greater, it means that the memory can store the lost packet information. In this case, the original lost packet information is written into memory, the new message is discarded, and the lost packet information of the new message is recorded. The lost packet information of the new message will be stored in the next storage.

[0077] In a preferred embodiment of the present invention, it further includes:

[0078] In response to a situation where the available memory space is less than the size of the lost packet information, both the lost packet information and the new message are discarded, and the lost packet information of the new message is recorded as new lost packet information to be sent. If the available memory space is less than the size of the lost packet information, i.e., the memory cannot store the lost packet information, the original lost packet information is discarded, the lost packet information of the new message is recorded, and the multi-type lost packet flag in the lost packet information of the new message is marked to indicate that a multi-type lost packet event has occurred. At the same time, the lost packet count is incremented by 1 to indicate that two lost packet events have occurred.

[0079] In a preferred embodiment of the present invention, it further includes:

[0080] Mark the various types of packet loss flags in the new packet loss information to be sent.

[0081] In a preferred embodiment of the present invention, the format of the packet loss information includes a packet loss information flag, a packet loss type, a packet loss count, and a multi-type packet loss flag, wherein the packet loss information flag is used to indicate that the message is packet loss information, the packet loss type is used to record the type of the current packet loss, the packet loss count is used to record the number of packets lost under the current packet loss type, and the multi-type packet loss flag is used to indicate that multiple different types of packet loss have occurred.

[0082] This invention implements a method for handling message packet loss. It determines whether packet loss is necessary based on the message size and the remaining space in memory. A built-in packet loss information buffer records the type and quantity of packet loss information. If consecutive packet losses of the same type occur, only one packet loss message needs to be written to memory, avoiding multiple transmissions of the same packet loss information. By adding a delay module, packet loss information can be sent before message information, allowing the number of packet losses between two messages to be determined through parsing the final output message. Multiple packet loss flags within the packet loss message can analyze whether other types of packet loss have occurred. For the message receiver, there may be one or more packet loss messages between two normal messages. If it is a single packet loss message, the multiple packet loss flags within it determine whether multiple different types of packet loss have occurred. If not, the packet loss message records the packet loss type and quantity between the two normal messages. If multiple different types of packet loss have occurred, the packet loss message records the latest packet loss type and the quantity of that type of loss. If there are multiple lost packets between two normal messages, then each lost packet message should be parsed using the method described above.

[0083] Based on the above objectives, a second aspect of the embodiments of the present invention provides an apparatus for handling message packet loss, such as... Figure 2 As shown, the device includes:

[0084] The controller is configured to receive new messages and process them based on the relationship between available memory space and the message size. The controller's input signals are the message, its corresponding type and size information, and the remaining memory space. The output is a write-to-memory signal. If the available memory space is greater than the message size, the new message is written directly to memory. If the available memory space is less than the message size, the new message is discarded, and its loss information is written to memory.

[0085] The memory is configured to store new messages or packet loss information and provides real-time feedback of available memory space to the controller. The memory is used to store received messages or packet loss information and requires dedicated read and write interfaces, meaning reads and writes can occur simultaneously (e.g., FIFO, dual-port RAM). The memory write interface supports a rate no lower than the message input rate. The memory needs to output remaining space information to the comparator module. When the remaining memory space is less than the amount of data to be written, packet loss information is generated. The remaining memory space is the actual remaining memory space minus the amount of data cached in the controller.

[0086] The memory read module is configured to read messages or packet loss information stored in the memory and output them. This module reads the data stored in the memory and outputs it to the next level, which is the destination of the message content. The memory read rate is affected by the data receiving capability of the next level. The greater the data receiving capability of the next level, the less packet loss occurs, and vice versa.

[0087] In a preferred embodiment of the present invention, such as Figure 3 As shown, the controller includes:

[0088] A comparator configured to compare the size of a newly received message with the available memory space.

[0089] A packet loss information caching unit is provided, with its input connected to a comparator and configured to store the packet loss information output by the comparator.

[0090] A message buffer unit, the input of which is connected to a comparator and configured to store the messages output by the comparator;

[0091] The delay unit has its input connected to the output of the message buffer unit and is configured to delay the delivery of messages output by the message buffer unit.

[0092] The selector has its inputs connected to the packet loss information buffer unit and the delay unit, respectively, and is configured to output the message output by the message buffer unit or the packet loss information output by the packet loss information buffer unit to the memory.

[0093] When a new message is received, it first enters the comparator. The first case is that there is no data in the packet loss information buffer. In this case, the message size of the received new message is compared with the available memory space. If the available memory space is less than the message size, the new message is discarded, and its packet loss information is written to the packet loss information buffer. If the available memory space is greater than the message size, the new message is written to the message buffer. The second case is that the packet loss information buffer contains packet loss information. In this case, the available memory space is compared with the sum of the new message size and the size of the packet loss information. If the available memory space is greater than or equal to the sum of the new message size and the size of the packet loss information, the packet loss information is written to the packet loss information buffer, and the new message is also written to the message buffer. If the available memory space is less than the sum of the new message size and the size of the packet loss information, it is determined whether the message type of the new message matches the packet loss type in the packet loss information. If the message type matches, the new message is discarded, and the packet loss count in the packet loss information is incremented by 1. If the message type of the new message is inconsistent with the packet loss type of the packet loss information, it is determined whether the available memory space is greater than or equal to the size of the packet loss information. If the available memory space is greater than or equal to the size of the packet loss information, the packet loss information is written into the memory, and the packet loss information of the new message is written into the packet loss information cache unit. If the available memory space is less than the size of the packet loss information, the packet loss information and the new message are discarded, and the packet loss information of the new message is written into the packet loss information cache unit.

[0094] Since message input is not subject to backpressure from memory, and packet loss information needs to be written before message information, a delay module needs to be added to delay message information writing. Packet loss information is then sent to memory ahead of time using this delay, and the delay time is no less than the time it takes to write the packet loss information to memory. When there is no need to write packet loss information to memory, the message writing path is: message buffer unit -> delay unit -> selector -> memory. When both packet loss information and message information need to be written simultaneously, the message writing path is: message buffer unit -> select to write packet loss information -> delay unit (packet loss information written) -> select to write message -> memory. The specific cases are explained below:

[0095] 1. Upon receiving a message, if there is no packet loss information to be sent internally, check if the available storage space is greater than or equal to the new message size. If so, choose to write the received message into storage. Figure 4 As shown.

[0096] 2. Upon receiving a message, if there is already packet loss information to be sent internally, determine if the available memory space is greater than or equal to the new message size plus the packet loss information size. If so, first write the packet loss information into memory, and then write the received message into memory. Figure 5 As shown.

[0097] 3. If the available memory space is less than the size of the new message plus the size of the lost packet information, then:

[0098] 3.1) If the type of the message received is consistent with the type of the packet loss information recorded, the packet loss count is incremented by 1, and the message is not written to the memory.

[0099] 3.2) If the type of the currently received message is inconsistent with the type of the recorded packet loss information, continue to check whether the available space in the memory is greater than or equal to the size of the packet loss information. If so, write the original packet loss information to the corresponding memory and record the new packet loss information; otherwise, discard the original packet loss information, record the packet loss information of the new message, record the new packet loss count, and mark multiple types of packet loss, such as... Figure 6 As shown.

[0100] In a preferred embodiment of the present invention, the comparator is further configured as follows:

[0101] Compare the size of the new message received with the available memory space;

[0102] In response to a situation where the available memory space is less than the message size of the new message, the new message is discarded and its packet loss information is written into the packet loss information cache unit.

[0103] In a preferred embodiment of the present invention, the comparator is further configured as follows:

[0104] Compare the size of the new message received with the available memory space;

[0105] In response to a situation where the available memory space is greater than the message size of the new message, the new message is written to the message buffer unit.

[0106] In a preferred embodiment of the present invention, the comparator is further configured as follows:

[0107] In response to the fact that packet loss information is stored in the packet loss information buffer unit, the available memory space is compared with the sum of the message size of the new message and the size of the packet loss information;

[0108] In response to a situation where the available memory space is greater than or equal to the sum of the message size of the new message and the size of the lost packet information, the lost packet information is written into the lost packet information cache unit, and the new message is written into the message cache unit.

[0109] In a preferred embodiment of the present invention, the comparator is further configured as follows:

[0110] In response to a situation where the available memory space is less than the sum of the message size of the new message and the size of the packet loss information, it is determined whether the message type of the new message is consistent with the packet loss type of the packet loss information;

[0111] If the message type of the new message matches the packet loss type in the packet loss information, discard the new message and increment the packet loss count in the packet loss information by 1.

[0112] In a preferred embodiment of the present invention, the comparator is further configured as follows:

[0113] If the message type of a new message is inconsistent with the packet loss type of the packet loss information, determine whether the available storage space is greater than or equal to the size of the packet loss information.

[0114] In response to the available memory space being greater than or equal to the size of the lost packet information, the lost packet information is written into the memory, and the lost packet information of the new message is written into the lost packet information cache unit.

[0115] In a preferred embodiment of the present invention, the comparator is further configured as follows:

[0116] In response to the available memory space being less than the size of the lost packet information, the lost packet information and the new message are discarded, and the lost packet information of the new message is written into the lost packet information buffer unit. The lost packet count in the new lost packet information is 2.
