Description

Technical Field

[0001] The present invention belongs to the field of network communication technology, and in particular relates to a time jump processing method, system, device and readable storage medium. Background Art

[0002] With the rapid growth of data volume in data networks, higher and higher requirements are placed on network quality. When problems occur in the intermediate links, it is necessary to quickly switch to backup link nodes to enhance the reliability and stability of the network.

[0003] In the TSN protocol family derived from this, the 802.1Qbv protocol is used to achieve precise data delay control. By adding time-sensitive Gate threshold control to the message at the egress, time-sensitive traffic can be accurately forwarded at the specified time. The 802.1Qbv protocol needs to run the 802.1Qbv state machine (802.1Qbv protocol) after the 802.1AS protocol (hereinafter referred to as PTP) completes time synchronization. At this time, the timestamp fluctuation of PTP will affect the 802.1Qbv state machine.

[0004] After the PTP timestamp changes, the configuration items of the Qbv state machine can only be switched or continued according to the timestamp after the change, which will inevitably cause the actual working state of the Qbv state machine to be different from the expected working state, affecting the normal operation of the Qbv state machine and even causing disorder in the TSN network environment.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a method for processing the 802.1Qbv protocol when the PTP timestamp jumps.

[0021] If the difference is a positive value, the PTP timestamp jumps to the future direction;

[0022] If the difference is a negative value, the PTP timestamp jumps to the past direction.

[0023] In one or more implementations of the present invention, determining whether the PTP timestamp jump is an abnormal jump includes:

[0024] If the jump value of the PTP timestamp is greater than or equal to the preset abnormal threshold, the current PTP timestamp jump is an abnormal jump;

[0025] If the jump value of the PTP timestamp is less than the preset abnormal threshold, the current PTP timestamp jump is ignored.

[0026] In one or more embodiments of the present invention, the method further comprises:

[0027] When an abnormal jump occurs, the first debug register is preset to increase by one;

[0044] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0045] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0046] Please refer to Figure 1 FIG. 1 is a flow chart of a time jump processing method according to an embodiment of the present invention. The time jump processing method specifically includes the following steps:

[0047] S101: Obtain the size and direction of the PTP timestamp jump value;

[0048] The clock structure of PTP is a master-slave clock mode. By continuously exchanging PTP messages, the timestamps of the master-slave clock message sending and receiving are obtained. The slave clock completes the time deviation calculation and network delay estimation, and corrects the local clock to achieve the purpose of master-slave clock synchronization. The PTP clock system is self-organizing management, and the master-slave clock status in each PTP domain is determined by the best masterclock (BMC) algorithm.

[0049] The IEEE802.1Qbv standard optimizes real-time traffic transmission through time-aware scheduling and multi-priority mechanisms to ensure low latency and high timing. When implementing precise data delay control based on the 802.1Qbv protocol, in order to ensure that time-sensitive traffic can be accurately forwarded at the specified time, time synchronization is required before the Qbv state machine runs. It is understandable that if the PTP timestamp fluctuates at this time, it will affect the normal operation of the subsequent state machine.

[0050] It should be noted that the reasons for the timestamp jump are various, including but not limited to network reasons, configuration reasons, etc. For example, the server has not been synchronized for a long time, resulting in time deviation; there is a problem with the IP configured on the server; the system time of the server has been tampered with manually, etc.

[0051] It is understandable that if Figure 2 As shown, it is a schematic diagram of the PTP timestamp jump in one embodiment of the present invention. The jump of the PTP timestamp can be forward (toward the future direction) or backward (toward the past direction). The jump direction and distance of the PTP timestamp will have different effects on the operation of the state machine. Therefore, in order to cooperate with the subsequent processing strategies corresponding to different situations of the present invention, the size and direction of the PTP timestamp jump value should be obtained first.

[0052] In an exemplary embodiment, the size and direction of the PTP timestamp jump value are obtained, including: periodically obtaining the deviation time recorded in a preset PTP deviation time register; calculating the absolute value of the difference between the deviation time obtained this time and the deviation time obtained last time as the value of the current PTP timestamp jump; if the difference is a positive value, the PTP timestamp jumps to the future direction; if the difference is a negative value, the PTP timestamp jumps to the past direction.

[0053] In an embodiment of the present invention, PTP time synchronization preferably adopts a relative time synchronization strategy. That is, for the master and slave clocks, although the absolute time at the same moment is different, the difference between adjacent sampling points is the same, and the master and slave clocks measure time in a consistent manner. In other words, at any moment, the time difference between the master and slave clocks is the same. Specifically, the implementation of the PTP protocol is based on two registers, one of which is a relative time register and the other is a deviation time register. The relative time register increments by one every 1 second, and the value recorded in it is the absolute time value, which is also the time value of the master clock; the deviation time register records the difference between the master and slave clock times. In an embodiment of the present invention, there is no restriction on the provisions of absolute time. In order to facilitate configuration and calculation, Beijing time is preferably used as the absolute time.

[0054] For example, if the absolute time is the same as Beijing time, both are 13:00, then the relative time register stores 13 hours. The slave clock is 14:00, which is one hour different from Beijing time. The value in the deviation time register is one hour in the positive direction. In the relative time synchronization strategy, the relative time register increments by one every second. During the continuous synchronization process, the value in the deviation time register is expected to be 1 hour, indicating that the master and slave clocks measure time in a consistent manner. At one moment, the master clock time is 15:00, and the slave clock time changes to 16:10. Compared with the previous moment, the value in the deviation time register jumps from 1 hour to 1 hour and 10 minutes. Therefore, the difference between the values ​​sampled twice for the deviation time register can be calculated, and the current PTP timestamp jump value is 10 minutes; since the difference is a positive value, this jump is a forward jump (jumping towards the future).

[0055] In a specific embodiment, the time jump processing system implementing the present invention is configured with a sampling calculation unit, which can sample the deviation time register based on a preset period, calculate the difference between the current sampling value and the sampling value at the previous moment, and output the absolute value of the difference. On the other hand, if the difference is a positive value, the corresponding Nagitive register is set to 0; if the difference is a negative value, the corresponding Nagitive register is set to 1. In order to identify the size and direction of the PTP timestamp jump value. It can be understood that the embodiment of the present invention does not limit the configuration of the sampling period, and the time sensitivity can be dynamically adjusted based on the actual implementation scenario.

[0056] S102: Determine whether the PTP timestamp jump is an abnormal jump;

[0057] In an exemplary embodiment of the present invention, judging whether the PTP timestamp jump is an abnormal jump includes: if the jump value of the PTP timestamp is greater than or equal to a preset abnormal threshold, the current PTP timestamp jump is an abnormal jump; if the jump value of the PTP timestamp is less than the preset abnormal threshold, the current PTP timestamp jump is ignored.

[0058] It is understandable that for the slight jump of the PTP timestamp, its influence on the operation of the Qbv state machine is small, so it can be ignored or processed by other means to reduce the waste of system load. In an exemplary embodiment, after a slight jump occurs in the PTP timestamp (after the jump value of the PTP timestamp is less than the abnormal threshold), the system can dynamically adapt the transmittable bit. Specifically, the dynamic adaptation of slight jumps is realized by the absolute time maintained inside the Qbv register. For example, the expected deviation time is 1000ns. After PTP calibration, the deviation time is 1200ns, that is, a PTP timestamp jump of 200ns occurs. If the message is transmitted at this time, the Qbv module will rely on the absolute time maintained by itself for transmission to avoid the problem of overrun.

[0059] It should be noted that the abnormal threshold can be implemented by configuring register variables. The specific implementation of the abnormal threshold in the present invention depends on the system configuration and may not be limited to software implementation or hardware implementation; the specific value of the abnormal threshold can be dynamically configured based on the actual use scenario of the present invention. The embodiment of the present invention does not limit the implementation method of the abnormal threshold and the specific value of the abnormal threshold.

[0060] S103: If the PTP timestamp changes abnormally toward the past time, each configuration item of the Qbv state machine is reloaded based on the current Qbv configuration information.

[0061] It should be noted that the 802.1Qbv protocol specifies configuration items such as AdminCycleTime, AdminBasetime, and Transmission Gate for the normal operation of the 802.1Qbv state machine, and these parameters are affected by PTP. Under normal operation, different time periods may require different configurations, but triggering changes to configuration items in the 802.1Qbv protocol requires waiting for the calculated preset configuration change time (Config Change Time).

[0062] It should also be noted that the deviation time stored in the deviation time register is the difference between the current local time (slave clock time) and the absolute time (master clock time), which can be used on the slave clock side to calculate the final absolute time. The reason why the jump of the PTP timestamp affects the operation of the subsequent Qbv state machine is that when the deviation time changes, the time sent to the Qbv state machine through the pulse is different from the absolute time of the previous time. In the time period spanned by the jump, there may be a time point where the configuration needs to be changed. If the configuration before the jump is maintained after the jump, it will cause the state machine to be abnormal.

[0063] On the other hand, because there is an uncontrollable time period, namely the end of cycle time, during the execution of the Qbv protocol, the maintenance of the end of cycle time is completed by maintaining the remaining time of the current threshold. When the time jumps backward, even if the jump process does not cross the preset configuration change time, it may still extend the duration of the old configuration, causing the end of cycle time to become an uncontrollable time. The user end cannot judge how many bits can be transmitted based on the remaining time, which will cause the state machine to be abnormal.

[0064] It should be noted that the PTP timestamp may jump toward the past or the future, and there may be one or more configuration change time points. If the PTP timestamp jumps abnormally toward the past time, there are two situations: one is that there is no configuration change time in the time period spanned by the jump; the other is that there is a configuration change time in the time period spanned by the jump.

[0065] It is understandable that if there is a configuration change time in the time period spanned by the abnormal jump to the past, it is equivalent to using the configuration of the current time at the past time point where the old configuration should be used, which will inevitably cause the state machine to be abnormal. Therefore, it is necessary to reload the various configuration items of the Qbv state machine based on the state configuration information at the time point after the jump. On the other hand, even if there is no configuration change time in the time period spanned by the abnormal jump to the past, it will also cause the cycle end time to be uncontrollable due to the prolonged duration of the current configuration, making the state machine abnormal. Therefore, it is necessary to reload the various configuration items of the Qbv state machine based on the state configuration information at the time point after the jump, and recalculate the corresponding cycle time and other configuration information to make the state machine run normally.

[0066] Similarly, there are two situations when the PTP timestamp jumps to the future: one is that there is no configuration change time in the time period spanned by the jump; the other is that there is a configuration change time in the time period spanned by the jump. However, it should be noted that if the configuration change time is not spanned, the abnormal jump to the future direction will not extend the duration of the current configuration, but will shorten the duration of the current configuration. Therefore, you can choose to reconfigure or ignore this jump and wait for the next configuration change time to load the new configuration.

[0067] Therefore, the time jump processing method provided by the present invention also includes: if the PTP timestamp jumps abnormally in the future time direction, and the PTP timestamp jumps to after the preset configuration change time, then the Qbv configuration information after the configuration change time is obtained; based on the Qbv configuration information after the configuration change time, the configuration items of the Qbv state machine are reloaded. If the PTP timestamp jumps abnormally in the future time direction, and the PTP timestamp jumps to before the preset configuration change time, the configuration items of the Qbv state machine are reloaded based on the current Qbv configuration information, or this abnormal jump is ignored.

[0068] In addition, in the embodiment of the present invention, a first debug register and a second debug register are maintained. The first debug register and the second debug register are both initialized to 0. When an abnormal jump occurs, the first debug register is preset to increase by one; when a negligible jump occurs, the second debug register is preset to increase by one.

[0069] This debug register can be used to locate system problems. By debugging, the number of small jumps (jump value less than the abnormal threshold) and abnormal jumps (jump value greater than or equal to the abnormal threshold) of the PTP timestamp can be counted. Combined with the register of Qbv itself, it can help users observe the status of the Qbv state machine.

[0070] Please refer to Figure 3 As shown, based on the same inventive concept as the aforementioned time jump processing method, an embodiment of the present invention provides a time jump processing system 300 , which includes: an acquisition module 301 , a judgment module 302 and a processing module 303 .

[0071] Specifically, the acquisition module 301 is used to obtain the size and direction of the PTP timestamp jump value; the judgment module 302 is used to judge whether the PTP timestamp jump is an abnormal jump; the processing module 303 is used to reload each Qbv configuration item based on the current Qbv configuration information when the PTP timestamp jumps abnormally in the past time direction.

[0072] It should be noted that the processing module 303 is also used to obtain the Qbv configuration information after the configuration change time if the PTP timestamp changes abnormally in the future time direction and the PTP timestamp changes to after the preset configuration change time; based on the Qbv configuration information after the configuration change time, reload the configuration items of the Qbv state machine. If the PTP timestamp changes abnormally in the future time direction and the PTP timestamp changes to before the preset configuration change time, reload the configuration items of the Qbv state machine based on the current Qbv configuration information, or ignore this abnormal change.

[0073] The acquisition module 301 is also used to periodically acquire the deviation time recorded in the preset PTP deviation time register; calculate the absolute value of the difference between the deviation time acquired this time and the deviation time acquired last time as the value of the current PTP timestamp jump; if the difference is a positive value, the PTP timestamp jumps to the future direction; if the difference is a negative value, the PTP timestamp jumps to the past direction.

[0074] The judgment module 302 is also used to determine that if the jump value of the PTP timestamp is greater than or equal to a preset abnormal threshold, the current PTP timestamp jump is an abnormal jump; if the jump value of the PTP timestamp is less than the preset abnormal threshold, the current PTP timestamp jump is ignored.

[0075] It should also be noted that the time jump processing system 300 provided by the present invention also includes a statistical module, which is used to preset the first debug register to increment by one when an abnormal jump occurs; and to preset the second debug register to increment by one when a negligible jump occurs.
