In view of the above object, an aspect of the embodiments of the present invention provides a method for synchronizing white box switch time in batches, as shown in fig. 1, including the following steps:
step S101: each switch system in the same local area network sends a broadcast message to the local area network, and transmits the IP address and the time mode of the switch system back to the sent switch system in response to receiving the broadcast messages of other switches;
step S102: the sent exchanger system analyzes the received information and locally maintains a mapping table of the IP address and the time mode thereof;
step S103: in response to receiving a configuration instruction containing a time mode, any switch system in the local area network updates a locally maintained mapping table according to the time mode so as to modify the time modes corresponding to all IP addresses in the mapping table into the time mode;
step S104: and traversing the updated mapping table by the switch system to send a synchronous time instruction to each IP address recorded by the switch system, wherein the switch system corresponding to each IP address modifies the time mode of the switch system into the corresponding time mode in the mapping table.
In some embodiments, the switch system includes a BMC system and a CPU system. Because the method for synchronizing time has universality no matter in a BMC system, a CPU system or other possible systems needing the synchronizing time.
In some embodiments, the respective port numbers of the messages of the BMC system and the CPU system are different, and each of the systems only monitors the messages between the systems and are independent of each other.
In some embodiments, the BMC system and the CPU system each maintain a mapping table of the IP address of their respective systems and their time patterns locally. The BMC system and the CPU system respectively maintain a mapping table of the system and do not influence each other.
In some embodiments, the time mode comprises a real time clock chip mode (RTC) or a network time protocol mode (NTP).
In some embodiments, modifying the time pattern of the switch system corresponding to each IP address to the corresponding time pattern in the mapping table comprises: in response to the time mode being a network time protocol mode, setting an address of the network time protocol server in the switch system and restarting its network time protocol service to synchronize time from the network time protocol server; in response to the time mode being a real time clock chip mode, the switch system synchronizes time from system hardware.
In an embodiment according to the present invention, after a switch system in the same lan is powered on, UDP (User Datagram Protocol) broadcast messages are sent to the local area network at regular time and in sequence, for example, sent every minute in sequence, and the period is determined according to the actual situation; meanwhile, each switch system also receives UDP broadcast messages sent by other systems in the local area network, and the messages are used for informing the receiving end to reply the IP address of the receiving end and the current time synchronization mode of the receiving end. The CPU system and the BMC system have different UDP message port numbers, only monitor messages between the systems and are independent of each other. When the on-line system receives the broadcast message, it will transmit its own IP address and its current time pattern (RTC or NTP) to the sending switch. The transmitted switch system receives the return information message, analyzes the IP address of the receiving end and its current time synchronization mode from the return information message, and maintains a mapping table locally, as shown in table 1.

As can be seen from the above description, each switch system is both a sending end and a receiving end, and after a period of time, the system of each switch maintains such a complete mapping table, from which the IP addresses and time synchronization patterns of all systems in the lan can be found.
The automated configuration script is designed to send a configuration instruction to any switch system in the lan, where the instruction is, for example, as follows:
start-time-sync.sh–t bmc–ip 100.1.1.2–m ntp–n ntp1.com
start-time-sync.sh–t cpu–ip 100.100.100.2–m rtc
wherein, the instruction parameter includes: -t: a target system type; -ip: a target system IP address; -m: a time synchronization mode; -n: if the mode is NTP, an NTP server address needs to be provided. After receiving the instruction, the target system analyzes the field content of the m mode in the instruction, updates a mapping table maintained locally, and modifies all time modes into modes required by the instruction; after updating the local mapping table, the system starts traversing the mapping table, and sends a synchronization time instruction to each IP address in the table, for example:
execute-time-sync–p 100.1.2.3–m ntp|rtc
after receiving the instruction, the target system corresponding to the IP address resolves the synchronization mode of the-m field, then updates the time synchronization configuration of the local system, and actually executes the synchronization time operation: if the mode is NTP, setting the NTP server address, and then restarting the NTP server to update the time; if the mode is RTC, the slave system hardware synchronizes the time.

5. The method of claim 1, wherein the time mode comprises a real time clock chip mode or a network time protocol mode.
6. The method of claim 5, wherein modifying the time pattern of the switch system corresponding to each IP address to the corresponding time pattern in the mapping table comprises:
in response to the time mode being a network time protocol mode, setting an address of the network time protocol server in the switch system and restarting its network time protocol service to synchronize time from the network time protocol server;
in response to the time mode being a real time clock chip mode, the switch system synchronizes time from system hardware.
7. An apparatus for synchronizing white box switch time in batches, comprising:
at least one processor; and
a memory storing program code executable by the processor, the program code implementing the following steps when executed by the processor:
each switch system in the same local area network sends a broadcast message to the local area network, and transmits the IP address and the time mode of the switch system back to the sent switch system in response to receiving the broadcast messages of other switches;
the sent exchanger system analyzes the received information and locally maintains a mapping table of the IP address and the time mode thereof;
in response to receiving a configuration instruction containing a time mode, any switch system in the local area network updates a locally maintained mapping table according to the time mode so as to modify the time modes corresponding to all IP addresses in the mapping table into the time mode;
and traversing the updated mapping table by the switch system to send a synchronous time instruction to each IP address recorded by the switch system, wherein the switch system corresponding to each IP address modifies the time mode of the switch system into the corresponding time mode in the mapping table.
8. The apparatus of claim 7, wherein the switch system comprises a BMC system and a CPU system.
9. The apparatus of claim 8, wherein the respective port numbers of the BMC system and the CPU system are different, and each system only listens for messages between the systems.
10. The apparatus of claim 9 wherein the BMC system and the CPU system each maintain a mapping table of IP addresses of their respective systems and their time modes locally.
