Wherein processor 301 includes one or more CPUs. The CPU may be a single-core CPU (single-CPU) or a multi-core CPU (multi-CPU), in which the CPU includes a plurality of transistors, and the greater the number of transistors per unit area, the stronger the processing capability of the CPU.
Optionally, the processor 301 implements the method for processing the dual master fault provided in the embodiment of the present application by reading the instruction stored in the memory 302, or the processor 301 implements the method for processing the dual master fault provided in the embodiment of the present application by using an instruction stored inside.

Optionally, the processing device of the dual master failure further includes a bus 304, and the processor 301, the memory 302, and the network interface 303 are generally connected to each other through the bus 304, or are connected to each other in other manners.
An embodiment of the present application provides a method for processing a dual master failure, where the method is applied to a first device, and the first device and a second device have a master-slave relationship, as shown in fig. 4, the method may include S400 to S402.
S400, the first equipment monitors double main faults between the first equipment and the second equipment.
It should be noted that, the first device may be a master device or a standby device, and when the first device is the master device, the second device is the standby device; when the first equipment is standby equipment, the second equipment is main equipment; wherein, the first device and the second device may both be forwarding devices in the diagram (a) in fig. 2; or both may be the storage devices in FIG. 2 (B); or both may be the computing devices in figure 2 (C). The embodiment of the present application specifically does not limit the active/standby roles and the device types of the first device.
The double main fault is a fault that a first link connected between a first device and a second device is in fault, so that the first device and the second device are both main devices, wherein the first link is used for mutually synchronizing data between the first device and the second device (namely, the first link is used for mutually synchronizing data between the first device and the second device), so that after one of the two devices with the main-standby relationship is down, the other device can replace the down device to work.
It should be understood that, when the first device and the second device have a primary-standby relationship, the first device and the second device provide a common physical address (abbreviated as an external MAC address) for devices other than the first device and the second device in the current system according to respective physical addresses (MACs), where the external MAC address is a MAC address of a primary device in the first device and the second device. When double-master failure does not exist between the first equipment and the second equipment, the first equipment and the second equipment mutually send original MAC addresses through a second link; when a dual-master failure exists between the first device and the second device, the standby device of the first device and the second device may also become a master device, and at this time, the first device and the second device mutually send an external MAC address through the second link.
Illustratively, assume that the first device is a master device with a MAC address of abc.. 1; the second device is a standby device, and the MAC address of the second device is ABC. Then the external MAC addresses of the first device and the second device are abc.. 1; when double main faults do not exist between the first equipment and the second equipment, the second equipment sends the MAC address ABC. When a double-master failure exists between the first device and the second device, at this time, the MAC address of the second device itself becomes an external MAC address, and therefore, the second device sends the MAC address of the second device abc.
The specific implementation of S400 may be that the first device determines according to the MAC address of the first device and the MAC address of the second device, where when the MAC address of the first device is different from the MAC address of the second device, there is no dual master failure between the first device and the second device; when the MAC address of the first device is the same as the MAC address of the second device, a double-master failure exists between the first device and the second device.
As shown in fig. 5, the specific implementation of S400 includes: s400a-S400b.
S400a, the first device receives the second MAC address sent by the second device.
The second MAC address is a MAC address of the second device.
It should be noted that, since the dual master failure is caused by a failure of a first link between the first device and the second device, the first device is a second MAC address received on the second link; the first link is a link for mutually synchronizing data between the first device and the second device, and the second link is a link between the first device and the second device except the first link.
S400b, the first device determines whether double-master failure exists between the first device and the second device according to the first MAC address and the second MAC address.
The first MAC address is a MAC address of the first device.
When the first MAC address is the same as the second MAC address, double main faults exist between the first equipment and the second equipment; when the first MAC address is different from the second MAC address, no double-master failure exists between the first device and the second device.
When there is no dual master failure between the first device and the second device, the first device periodically performs the above S400a-S400b.
When there is a double master failure between the first device and the second device, the first device performs the following S401 to S402.
Optionally, the above dual-master failure monitoring may also be applied to the first device and the second device, and the specific implementation manner is similar to that of S400a-S400b, which is not described herein again.
S401, under the condition that double main faults exist between the first device and the second device, the first device determines a target device.
The target device is a device with a poor health status in the first device and the second device, wherein the device with the better health status has a larger number of available resources.
For example, assume that the total computing power on the processors (CPUs) of the first device and the second device is the same, where the idle computing power of the first device is 80% and the idle computing power of the second device is 50%; then, the first device compares the idle calculation power of the first device with the idle calculation power of the second device after acquiring the idle calculation power of the first device, and determines the second device with less idle calculation power, that is, the device with poor health state, as the target device.
The health status of the second device is obtained by the first device from the second device through the second link. The specific obtaining manner may be that the first device sends an obtaining request to the second device, and the second device sends the health status of the second device to the first device after receiving the obtaining request. Or the health status of the second device that the second device actively sends to the first device.
The health status of the first device is determined by the first device, and the specific determination manner is as follows in S601, which is not described herein again.
It should be noted that the health status of the device may be represented by at least one characteristic, or may be represented by the health status of the device, and the specific form of the health status of the device is not limited in the present application.
S402, when the target device is a first device, the first device quits the system where the first device and the second device are located.
The system for the first device to exit the first device and the second device comprises: the first device executes shutdown operation, or the first device closes service interfaces (such as all service interfaces) on the first device, so that the first device does not process services any more; the service interface is an interface used for processing a service on the first device, and the service interface may be a part or all of the network interface 303 in fig. 3, or may also be a virtual interface, and the specific form of the service interface is not limited in this application.
The service interface may be an interface for forwarding data, an interface for reading and writing data, or an interface for processing data (for example, converting data format).
For example, in the system shown in fig. 1, when there is a dual master failure in device a and device B, when device a is determined as a target device, device a performs shutdown operation and no longer performs data forwarding, so that device B performs data forwarding instead of device a; or the device A closes the interface on the device A for forwarding data to the Internet and closes the service interface for receiving tasks from the server, so that the device B replaces the device A for forwarding the data.
It should be noted that when the target device is the second device, the first device ends the method after S401 is executed.
Optionally, in the method for processing a dual master failure provided in this embodiment of the present application, when the target device is the second device, after the first device completes S401, the first device sends an exit instruction to the second device, so that after the second device receives the exit instruction, the second device exits from the systems where the first device and the second device are located.
The embodiment of the application provides a method for processing double-master failure, which is applied to a first device, wherein a master-slave relationship exists between the first device and a second device, and the method comprises the following steps: under the condition that double main faults exist between the first equipment and the second equipment, the equipment with poor health state autonomously closes an interface for processing services on the equipment, namely, the equipment exits from the current system, so that the equipment with good health state continuously works in the current system. Therefore, compared with the traditional method for processing the double-main fault, the method for processing the double-main fault provided by the application takes the health state of the main and standby equipment as the basis for judging whether to quit the current system, namely the equipment with poor health state quits the current system, and the equipment with good monitoring state is kept to work in the current system, so that the reliability and stability of the current system are improved.
Optionally, the method for processing a dual master failure provided in the embodiment of the present application may also be applied to a first device and a second device having a master-slave relationship, respectively; wherein, the first device and the second device may both be forwarding devices in the diagram (a) in fig. 2; or both of the first device and the second device may be the storage devices in the diagram (B) in fig. 2, or both of the first device and the second device may be the computing devices (e.g., servers) in the diagram (C) in fig. 2; taking the health value as an example, a specific implementation of the method may include, as shown in fig. 6: S601-S608.
S601, the first equipment determines a first health value according to the value of the target characteristic of the first equipment.
The higher the first health value, the better the health status of the first device; that is, the higher the first health value, the greater the amount of available resources on the first device.
It should be noted that the target feature is a feature for representing available resources on the first device, for example: when the first device is a computing device, the characteristics of the available resources include: at least one of an unused rate of the CPU, an unused rate of the memory, and an amount of idle computing power.
For example, assume that the target features include CPU and memory unavailability; the health value is the product of the sum of the CPU non-utilization rate and the memory non-utilization rate and 100; wherein, the CPU non-utilization rate of the first device is 30%, and the memory non-utilization rate of the first device is 50%; then, the first health value is calculated as the product of the sum (i.e. 80%) of the CPU's unused rate (i.e. 30%) and the memory's unused rate (i.e. 50%) multiplied by 100, which is 80: the first health value is 80.
It should be noted that, in this embodiment of the present application, the first device and the second device may be any one of devices such as a switch, a router, or a storage device, and a specific apparatus of the first device and the second device is not limited in this embodiment of the present application.
When the first device is a forwarding device, the target feature includes: the amount of available resources and device initialization features.
The device initialization feature is used to indicate whether the device completes initialization, for example, when the value of the device initialization feature is 0, it indicates that the device does not complete initialization; when the value of the device initialization feature is 1, it indicates that the device has completed initialization.
The available resource characteristics include at least one of: the method comprises the following steps of counting the number of non-failed transistors in a CPU (Central processing Unit) of the equipment, counting the number of non-failed transistors in an LSW (local area network) chip of the equipment, counting the available number of uplink ports of the equipment, and counting the non-utilization rate of a processor of the equipment or the non-utilization rate of a memory of the equipment, wherein the LSW chip of the equipment is used for data forwarding or data exchange, the processing capacity of the LSW chip of the equipment is determined by the number of the transistors in the LSW chip of the equipment, and the uplink ports of the equipment are ports connected with the Internet or a convergent network.
When the first device is a storage device, the target feature includes: the number of available storage resources and the number of available transmission channels for carrying read or write data.
Optionally, when the first device and the second device are forwarding devices, the specific implementation of S601 includes: the first equipment calculates a first health value according to the value of the target characteristic of the first equipment and the weight value of each characteristic in the target characteristic.
The feature weight value of the target feature having a greater influence on the service stability is greater.
For example, when the service is a data forwarding service, the features with weighted values from large to small in the target features may be: initialization characteristics of the device, the available number of upstream ports of the device, the number of non-failing transistors in the LSW chip of the device, the number of non-failing transistors in the processor of the device, the non-utilization rate of the processor of the device, and the non-utilization rate of the memory of the device. The first device determines whether the first device can normally operate or not by whether the first device completes initialization, so that the weight of the initialization feature of the first device is the largest, and the available number of uplink ports of the first device determines whether the received data can be forwarded or not, so that the weight is larger.
For another example, when the service is a data format conversion service, the features with weighted values from large to small in the target features may be: initialization characteristics of the device, the number of non-failing transistors in the device processor, the non-utilization rate of the device processor, the number of non-failing transistors in the device LSW chip, the non-utilization rate of the device memory, and the available number of device upstream ports.
In one implementation of the above calculating the first health value according to the value of the target feature of the first device and the weight value of each of the target features, the health value is a sum of products of the value of each of the target features of the first device and the weight value of each of the target features.
For example, assuming that the service is a data forwarding service, the initialization feature weight value is 300, the weight value of the available number of the uplink ports is 10, the weight value of the number of transistors that have not failed in the LSW chip is 8, the weight value of the number of transistors that have not failed in the processor is 6, the weight value of the non-utilization rate of the processor is 4, and the weight value of the non-utilization rate of the memory is 2. The first preset initialization characteristic value is 1, the available number of the upstream ports of the first device is 20, the number of the non-failed transistors in the LSW chip of the first device is 30, the number of the non-failed transistors in the processor of the first device is 40, the non-utilization rate of the processor of the first device is 80%, and the non-utilization rate of the memory of the first device is 60%. Then, first health value =300 + 1+20 + 10+30 + 8+40 + 6+0.8 + 4+0.6 + 2; from this, the first health value is 1084.4.
S602, the first device sends the first health value to the second device through the second link.
The second link is a link between the first device and the second device, and the second link is a link between the first device and the second device for performing dual master failure detection.
And S603, the second equipment calculates a second health value according to the value of the target characteristic of the second equipment.
The second health value is calculated by the second device according to the value of the target feature of the second device, wherein the first health value and the second health value are calculated in the same manner.
Illustratively, based on the example in S601, assuming that the CPU non-usage of the second device is 40% and the memory non-usage of the second device is 50%, the process of calculating the second health value by the second device is as follows: the product of the sum of the CPU unavailability (i.e., 40%) of the second device and the memory unavailability (i.e., 50%) of the second device multiplied by 100 is 90, i.e.: the second health value is 90.
It should be noted that the specific implementation of S603 is similar to S601, and for the specific description of S603, reference may be made to the related description of S601, which is not described herein again.
S604, the second device sends the second health value to the first device through the second link.
It should be noted that the specific implementation of S604 is similar to S602, and for the specific description of S604, reference may be made to the related description of S602, which is not described herein again.
And S605, the first equipment determines target equipment according to the first health value and the second health value.
The S605 specifically includes: the first device compares the first health value with the second health value, and determines the device with smaller health value as the target device.
Illustratively, based on the example of S603, the first device determines the device corresponding to the first health value (i.e., the first device) as the target device by comparing the first health value 80 with the second health value 90.
And S606, when the target equipment is the first equipment, the first equipment quits the system where the first equipment and the second equipment are located.
It should be noted that the specific implementation of S606 is similar to S402, and for the specific description of S606, reference may be made to the related description of S402, which is not described herein again.
And S607, the second equipment determines the target equipment according to the first health value and the second health value.
It should be noted that the target device is the same device as the target device in S605.
It should be noted that the specific implementation of S607 is similar to S605, and for the specific description of S607, reference may be made to the related description of S605, which is not described herein again.
And S608, when the target device is a second device, the second device quits the system where the first device and the second device are located.
It should be noted that the specific implementation of S608 is similar to S606, and for the specific description of S608, reference may be made to the related description of S606, and details are not repeated here.
According to the method for processing the double-master failure, the first equipment determines target equipment according to a first health value of the first equipment and a second health value sent by the second equipment; therefore, when the target characteristics comprise a plurality of characteristics, the first device only needs to receive the health value sent by the second device, and does not need to receive a plurality of characteristics in the target characteristics of the second device, so that the bandwidth occupied by the second device for sending the health state of the second device to the first device is saved.
In addition, the method for processing the double-master failure provided by the embodiment of the application is executed on both sides of the first device and the second device, so that the current system can be quitted at the first time no matter whether the target device is the first device or the second device when the target device is determined to be the target device, and therefore, the reliability and the stability of the current system are improved.
