Technical Field

Background
With the advent of 5G communication, the demand for time synchronization accuracy is higher and higher, and high-quality time synchronization becomes a key problem to be solved in the first place. The IEEE1588 time synchronization protocol (PTP protocol for short) is a high-precision time synchronization technology, and can be combined with a packet network to synchronize time signals with different precisions in a heterogeneous system into a uniform master time with the highest performance. Generally, the PTP protocol measures upstream and downstream time offsets and path delays in a message interaction manner, so that a downstream device corrects local time according to a measurement result and synchronizes with an upstream device. The existing device is usually configured with dual main control boards (a main control board and a standby main control board), and in the process of switching the main and standby main control boards, the prior art has solved the problem of time synchronization of the main and standby main control boards in the switching process, that is, after the main control board is switched to the standby main control board, the 1588 message can be sent quickly, and the message interruption time in the main and standby switching process is shortened, so as to achieve the purposes of stabilizing the network and reducing network oscillation. However, in the prior art, in the active/standby switching process, a short message sequence number confusion phenomenon occurs in PTP messages, and for messages that need to be matched in pairs according to sequence numbers, for example, delay _ req (delay request) messages and delay _ resp (delay response) messages, this may cause relatively large time jump due to mismatching of sequence numbers, thereby affecting the overall accuracy of time and affecting a time-sensitive network.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes in detail a message sending method, a terminal device, and a storage medium provided by the present invention with reference to the accompanying drawings.
Example embodiments will be described more fully hereinafter with reference to the accompanying drawings, but which may be embodied in different forms and should not be construed as limited to the embodiments set forth herein.

It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It will be understood that, although the terms first, second, etc. may be used herein to describe various elements/instructions/requests, these elements/instructions/requests should not be limited by these terms. These terms are only used to distinguish one element/instruction/request from another element/instruction/request.

It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present invention and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The message sending method provided by the invention can ensure the continuity of the message serial numbers sent to the opposite terminal equipment in the process of switching the main and standby main control boards, and particularly, the technical scheme of the invention is suitable for a sending scene of 1588 messages. In the following embodiments of the present invention, a sending scenario of a 1588 message will be described.
The 1588 message is a message sent by the master control board in the time synchronization process according to IEEE1588 time synchronization protocol (PTP for short), and in the active/standby switching process of the active master control board and the standby master control board, the problem of continuous sequence numbers of the 1588 message is not considered in the prior art.
Fig. 1 is a diagram of a message sending method provided by the present invention, where the method uses a terminal device as an execution main body, and as shown in fig. 1, the method includes:
step S101, the message serial number of the main master control board is sent to the standby master control board, so that the standby master control board refreshes the message serial number of the standby master control board, and the message serial number of the next message is continuous with the message serial number obtained by refreshing.
When the local terminal equipment transmits the message of the main control board to the opposite terminal equipment, the local terminal equipment transmits the message serial number of the message currently being transmitted by the main control board to the standby main control board, the standby main control board refreshes the message serial number of the standby main control board after receiving the message serial number of the main control board so as to update the message serial number of the standby main control board to be the same as the current message serial number of the main control board, thereby ensuring that the message serial number of the message transmitted by the standby main control board is continuous with the refreshed message serial number when the next message of the standby main control board is transmitted to the opposite terminal equipment, therefore, the message serial number of the message sent by the local terminal equipment can be ensured to be continuous with the message serial number of the message sent last time all the time.
Step S102, based on the master-slave relationship of the current master control board, determining a message sent by the current master control board, and sending the message sent by the current master control board to an opposite terminal device.
Before sending a message to an opposite terminal device, the local terminal device identifies the main-standby relationship of the current main control board, determines the message sent by the current main control board according to the main-standby relationship, and sends the message sent by the current main control board to the opposite terminal device.
In the invention, because the message serial numbers of the main control board and the standby main control board are synchronously updated to be the same in real time, the message serial number of the message sent to the opposite terminal equipment by the local terminal equipment can always be continuous with the last message serial number no matter whether the local terminal equipment is subjected to main/standby switching, thereby solving the problem that the 1588 message serial number is discontinuous before and after the main/standby switching in the prior art.
It should be noted that, in the present invention, the continuous message sequence numbers refer to that the message sequence numbers are continuous according to a certain preset rule, for example, the message sequence numbers are sequentially increased by 1, increased by 2, or the like, or are sequentially increased by alphabetical order, or are presented according to a certain rule according to a preset algorithm rule, or the like.
When sending a message to an opposite terminal device, the message serial number of the main control board is sent to the standby main control board so that the standby main control board updates the message serial number of the standby main control board to be the same as the main control board, so that the message serial number of the message sent by the current main control board (the original standby main control board before main standby switching) after the main standby switching is completed subsequently can be continued to the message serial number of the original main control board before the main standby switching, thereby realizing the continuity of the message serial number of the 1588 message before and after the main standby switching, and further avoiding the influence of the discontinuity of the 1588 message serial number on the time precision.
Fig. 2 is another message sending method provided by the present invention, and as shown in fig. 2, in this embodiment, on the basis of the method shown in fig. 1, step S102 specifically includes:
and S1021, receiving messages sent by all the main control boards.
Step S1022, based on the active-standby relationship of the current main control board, a message sent by the current active main control board is determined.
And S1023, discarding the message sent by the current standby main control board, and sending the determined message sent by the current main control board to the opposite terminal equipment.
In this embodiment, when the local device needs to generate a response packet in response to a packet sent by the opposite device, both the current main control board and the current standby main control board generate and send response packets, and send the response packets to a reprocessing module (described later) of the local device. The local terminal device determines the master-slave relationship of all current master control boards by inquiring system information, and then determines which of the received messages is the message sent by the current master control board by identifying the master control board identification carried in the received message based on the master-slave relationship of the master control boards, and discards the message sent by the current master control board after determining the message sent by the current master control board, for example, deletes the message sent by the current master control board and sends the message sent by the current master control board to the opposite terminal device, thereby realizing the interaction between the current master control board and the opposite terminal device.
Of course, in practical application, other embodiments of sending the message of the current active main control board to the opposite terminal device may also be adopted, and the present invention is not limited.
In the invention, the dual main control boards of the device are preset with 1588 functions by technicians in the field, specifically, the technicians in the field configure the main control board and the standby main control board with the function of simultaneously sending 1588 messages, and carry out consistency check on the main control board and the standby main control board to ensure the synchronization of the configuration of the main control board and the standby main control board.
In some embodiments, in step S101, sending the message serial number of the active main control board to the standby main control board may be implemented based on various ways.
As an optional implementation manner, the local device may send the message sequence number of the active main control board to the standby main control board on time. As shown in fig. 3 (fig. 3 is a flowchart of another message sending method provided by the present invention), step S101 may specifically include:
step S1011, based on the preset sending frequency, sending the message serial number of the main master control board to the standby master control board according to the preset sending frequency.
Wherein, the sending frequency should be higher than the 1588 message packet sending frequency of the local terminal equipment. In this embodiment, it can be ensured that the active main control board notifies the standby main control board to start sending the messages with the same serial number before sending the packet by setting the sending frequency, and when there are a plurality of PTP connections on the device, the local device can quickly notify the standby main control board of the serial numbers of 1588 messages in all PTP connections. In this embodiment, the configuration of the transmission frequency may be configured in the local device in advance by a person skilled in the art, and correspondingly, as shown in fig. 3, before step S1011, the method further includes step S1010: the transmission frequency is configured.
As another alternative implementation, the local device may send the message serial number of the active main control board to the standby main control board as needed. Specifically, as shown in fig. 4 (fig. 4 is a flowchart of another message sending method provided by the present invention), step S101 may specifically include:
step S1011', in response to the start of the active/standby switching process between the active main control board and the standby main control board, the message serial number of the active main control board is sent to the standby main control board according to the preset sending frequency.
When the local device needs to perform the main/standby switching between the main control board and the standby control board, the local device may send the message serial number of the main control board to the standby control board according to the preset sending frequency in response to the main/standby switching instruction.
In the above embodiment, in step S101, the sending manner of sending the message serial number of the active main control board to the standby main control board may be implemented based on a notification message format, where the notification message format includes: an 8K clock mode message format and an internal Ethernet port mode message format.
Fig. 5 is a schematic structural diagram of an 8K clock mode packet format according to the present invention, as shown in fig. 5, where: type: defined as 0x0C, identifying this message as a message sequence number notification message: ptplinkld: PTP link identification on the equipment; 3, Count: the identification message carries the serial numbers of several messages; messageType: the specific message type transmitted inherits the value of the type of the existing standard message; sequence ld: message sequence number.
One notification message at least carries the serial number of one message, and the serial numbers of other messages are sequentially filled in the data field according to the messageType and sequence.
Fig. 6 is a schematic structural diagram of an internal ethernet port mode packet format according to the present invention, as shown in fig. 6, where 1. EtherType: defining the message as 0x88FC, and marking the message as a message serial number notification message; ptplinkld: PTP link identification on the equipment; 3, Count: the identification message carries the serial numbers of several messages; messageType: the specific message type transmitted inherits the value of the type of the existing standard message; sequence ld: message sequence number.
One notification message at least carries a serial number of one message, the serial numbers of other messages are sequentially filled in the data field according to the messageType and sequence order, the length of the Ethernet message is at least 64 bytes, and if the length of the message does not meet the length of 64 bytes, the rest data are directly filled with all 0 s.
In some embodiments of the present invention, before step S101, that is, before the local device sends the message serial number of the main control board to the standby main control board, the local device obtains the message serial number of the main control board in advance, for example, the local device sends a request for obtaining the message serial number to the main control board at preset time intervals, or the local device actively sends the current message serial number to the local device when sending the message by performing configuration in advance.
Of course, in some other embodiments of the present invention, the local device may also directly send the message serial number to the standby main control board by the active main control board without acquiring the message serial number of the active main control board in advance.
Fig. 7 is a further message sending method provided by the present invention, as shown in fig. 7, the method includes:
step S201, determining a message of the main control board.
Step S202, based on the target message serial number generated by the continuous updating rule, the message serial number of the main master control board is updated to be the target message serial number.
Step S203, sending the updated message of the main control board to the peer device.
In the packet transmission method provided in this embodiment, before the local device sends a packet to the peer device, the local device determines the packet sent by the main control board, and then assigns a new packet serial number, which is continuous with the previous packet serial number, to the packet of the main control board based on a preset continuous update rule, so as to send the packet assigned with the new packet serial number to the peer device, so that the packet serial numbers of the packet can be kept continuous regardless of whether the packet sent by the local device is switched between the main control board and the peer device or not.
It should be noted that, in the present invention, the continuous message sequence numbers refer to that the message sequence numbers are continuous according to a certain preset rule, for example, the message sequence numbers are sequentially increased by 1, increased by 2, or the like, or are sequentially increased by alphabetical order, or are presented according to a certain rule according to a preset algorithm rule, or the like.
Fig. 8 is a flowchart of another message sending method provided by the present invention, where in this embodiment, on the basis of the method shown in fig. 7, step S201 specifically includes:
and step S2011, receiving the messages sent by all the main control boards.
Step S2012, determining a message of the active main control board based on the active-standby relationship between the active main control board and the standby main control board.
In this embodiment, when the local device needs to generate a response packet in response to a packet sent by the opposite device, both the current main control board and the current standby main control board generate and send response packets, and send the response packets to a reprocessing module (described later) of the local device. The local terminal equipment determines the main-standby relationship of all current main control boards by inquiring system information, and then determines which one of the received messages is the message sent by the current main control board by identifying the main control board identification carried in the received message based on the main-standby relationship of the main control boards.
Of course, in practical application, other manners of determining the message sent by the main control board may also be adopted, and the present invention is not limited thereto.
In addition, in the present invention, the dual main control boards of the device are preset with 1588 function settings by technicians in the field, specifically, technicians in the field configure the main control board and the standby main control board with a function of sending 1588 messages simultaneously, and perform consistency check on the main control board and the standby main control board to ensure that the main and standby main control boards are configured synchronously.
With continued reference to fig. 8, in some embodiments, while performing step S203, the method further includes:
step S204: and discarding the message of the standby main control board.
The local terminal device discards the message of the standby main control board, for example, deletes the message while sending the message of the main control board to the opposite terminal device, thereby avoiding resource occupation.
Of course, in practical applications, step S204 may be performed before or after step S203.
In some embodiments, the specific implementation procedure of step S202 is as follows: the home terminal equipment generates a target message serial number based on a continuous updating rule, analyzes the message of the main control board, updates a serial number field in the message into the target message serial number, and repackages the message to regenerate the message.
Fig. 9 is a schematic structural diagram of a terminal device provided in the present invention, which is used for implementing the message sending method shown in fig. 1 of the present invention, and as shown in fig. 9, the terminal device includes: a notification module 11 and a reprocessing module 12.

When the terminal device sends the message to the opposite terminal device, the message serial number of the main control board is sent to the standby main control board, so that the standby main control board updates the message serial number of the standby main control board to be the same as the main control board, and the message serial number of the message sent by the current main control board (the original standby main control board before the main-standby switching) after the main-standby switching is completed subsequently can be continued to the message serial number of the original main control board before the main-standby switching, so that the continuity of the message serial number of the 1588 message before and after the main-standby switching is realized, and the influence of the discontinuity of the 1588 message serial number on the time precision is further avoided.
In this embodiment, the functions of each module correspond to the steps of the method shown in fig. 1, and please refer to the description of the corresponding steps in the method shown in fig. 1, which is not described herein again.
It should be noted that, in practical application, the notification module may be a module independent from the main control board and the standby control board, which is disposed in the terminal device, or may be a functional module built in the main control board, so as to send the message serial number of the main control board to the standby control board.
