As shown in fig. 3, fig. 3 is a schematic flowchart illustrating a clock synchronization method according to an embodiment of the present application. The method may be applied to the network device in fig. 1. As shown in fig. 3, the method may include the steps of:
s100: and the terminal equipment sends a service request to be processed to the network equipment. The pending service request includes: the service type of the service requested to be processed by the service request to be processed.
Specifically, a terminal device in the campus network sends a service request to be processed to a network device.
Optionally, the pending service request further includes an account identifier of an account sending the pending service request.
Optionally, S101, the network device determines that the to-be-processed service request is verified according to the account identifier.
In a possible implementation manner, the network device forwards the account identifier to a corresponding server for authentication. And determining that the to-be-processed service request passes the verification under the condition that the network equipment receives the response message that the corresponding server passes the verification.
S102: and the network equipment synchronizes a clock with the core network equipment according to the service type of the service requested to be processed by the service request to be processed.
Specifically, as shown in fig. 4, a schematic flow chart of a method for synchronizing clocks between a network device and a core network device is shown:
the method comprises the following steps: the network equipment acquires the data volume to be processed. The pending data volume includes a data volume of a service requested to be processed by the pending service request.
Step two: and the network equipment judges whether the data volume to be processed is larger than a preset threshold value, if so, the third step is executed, and if not, the fourth step is executed.
Step three: the network equipment distributes resources for the service requested to be processed by the service request to be processed and synchronizes a clock with the core network equipment.
Specifically, the network device allocates resources to the data to be processed in sequence according to the priority order by using the resource scheduling algorithm, and synchronizes clocks with the core network device after the network device allocates resources to the service requested to be processed by the service request to be processed.
The method for synchronizing the clocks of the network device and the core network device may include the following steps S1 to S3:
s1: the network device obtains a path delay between the network device and the core network device.
In a possible implementation manner, the network device sends a measurement packet to the core network device, where the measurement packet includes a sending timestamp for the network device to send the measurement packet. The network equipment receives the response message of the measurement message responded by the core network equipment, and records the receiving time stamp of the response message. The network device obtains a time difference between the sending time stamp and the receiving time stamp, and the network device takes one half of the time difference as a path delay between the network device and the core network device.
In another possible implementation manner, the network device sends a Pdelay _ Req event packet to the core network device, and records a timestamp t sent1(ii) a After the core network equipment receives the Pdelay _ Req message sent by the network equipment, the core network equipment records the received timestamp t2(ii) a The core network device transmits the time stamp t2Packaging the event message into a Pdelay _ Resp event message, sending the message to network equipment, and recording a sending time stamp t3(ii) a The core network device will again time stamp t3Packing the event message into a Pdelay _ Resp _ Follow _ Up event message, and sending the event message to network equipment; after the network equipment receives the Pdelay _ Resp event message sent by the core network equipment, recording a receiving timestamp t4And resolves the timestamp t contained in the Pdelay _ Resp event message2(ii) a After the network device receives the Pdelay _ Resp _ Follow _ Up message sent by the core network device, the network device analyzes the timestamp t contained in the Pdelay _ Resp _ Follow _ Up message3(ii) a Thus, the network device receives four timestamps, t1，t2，t3，t4. The network device may calculate the path delay D by the following formula:
wherein, tirIndicating the path delay from the network device to the core network device, tirIndicating the path delay of the core network device to I.
It is understood that the network device may average the path delay through the above-mentioned steps for a plurality of measurements. Similarly, the network device and the core network device may also exchange roles, and the core network device obtains the path delay and then sends the path delay to the network device.
In another possible implementation manner, the network device requests the core network device for a request message for measuring the path delay, and the network device receives the path delay sent by the core network device.
In another possible implementation manner, the network device obtains a plurality of path delays through the two possible implementation manners, and obtains a path delay between the network device and the core network device according to the plurality of path delays. In one example, the network device obtains an average of the plurality of path delays as a path delay between the network device and the core network device.
In another possible implementation manner, the network device reads a pre-stored path delay between the network device and the core network device.
It can be understood that the network device may obtain and store the path delay between the network device and the core network device in advance in the resource idle period of the network device, so that the network device may directly obtain the pre-stored path delay, thereby accelerating the speed of service processing.
S2: the network device obtains a master clock of the core network device.
Specifically, the network device receives a master clock sent by the core network device.
In one example, a network device receives a master clock that the core network device transmits to the network device in accordance with a clock scheme defined in the ieee802.1as protocol.
The triggering condition for the core network device to send the master clock to the network device is not limited in the present application, and in an example, the core network device sends the master clock to the network device when receiving a request message for requesting the master clock sent by the network device. Optionally, the request message for requesting the master clock, sent by the network device to the core network device, further includes a charging field, where the charging field is used to instruct the core network device to charge the service requested to be processed by the service request to be processed.
S3: and the network equipment synchronizes the clock with the core network equipment according to the path delay and the master clock.
Specifically, the network device corrects the received master clock according to the path delay and synchronizes with the corrected master clock.
In a possible implementation manner, the core network device sends a Sync event message to the network device, and records a sending timestamp tM(ii) a The core network device transmits the time stamp tMPackaging the mixtureSending the Follow _ Up message to the network equipment; after the network equipment receives the Sync event message sent by the core network equipment, the network equipment records a receiving timestamp tS(ii) a After receiving the Follow _ Up message sent by the core network device, the network device analyzes the timestamp information t in the Follow _ Up messageM；
Based on the path delay D obtained in S1, the time difference between the core network device and the network device is obtained as follows:
offset＝ts-tM-D
clocks of the network device and the core network are synchronized according to the time difference offset.
In one example: assume that the path delay is 30 minutes, tM1 hour, then tsShould be 1.5 hours, if tsIf the clock is not 1.5, it indicates that the clock in the network device is inaccurate, and the clock in the network device is corrected according to the offset so as to be synchronized with the clock of the core network device.
Step four: the network device synchronizes clocks with the core network device.
Specifically, refer to the above steps S1 to S3, which are not described again.
In the embodiment of the application, an MEC server for processing services in a campus network is deployed in a network device, the network device judges whether a clock needs to be synchronized with a core network device according to a received service type of the network device, processes a service corresponding to a service type after synchronizing the clock with the core network device only when the service type needs to guarantee low delay and high reliability, and directly processes the service corresponding to the service type when the service type does not need to guarantee low delay and high reliability, so that the processing efficiency of the service is improved, and the low delay and high reliability of service processing is guaranteed.
