Description
Technical Field
The present application relates to the field of computer technologies, and in particular, to a method and an apparatus for synchronizing interface states.
Background
In network communication technology, a network device plays a role of network data transmission as a node device in a network link. Multiple network links typically exist in the same network device.
In order to ensure that data can be transmitted normally, when an interface of a network device determines that a network connected to the interface has a failure, the network device needs to quickly notify other network devices connected to the interface so that the device can select other network links for data transmission.
In practical applications, an interface state synchronization group function exists in a network device (e.g., network device 1). By this function, the administrator can configure some interfaces in the network device 1 as members in the same interface state synchronization group, and the interface states of the members in the group will remain automatically synchronized. Under the above situation, when any interface of the network device is in a failure state due to a failure of the network connected to the interface, the other interfaces in the interface state synchronization group automatically synchronize their interface states to a failure state, so that the network device connected to the network device 1 through the other interfaces can quickly acquire the other interface states of the network device 1, and accordingly, determine that the network link where the network device 1 is located is unavailable, and thereby replace the other network links for data transmission.

and updating the slave states of the interfaces except the target interface in the interface state synchronization group to the interface states respectively.
The application also provides an interface state synchronization device, which is applied to network equipment, wherein a plurality of interfaces of the network equipment are configured into an interface state synchronization group; the interface in the interface state synchronization group comprises a master state and a slave state; the above-mentioned device includes:
the determining module is used for determining whether the network connected with each interface in the interface state synchronization group has state change;

Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the exemplary embodiments below do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It should also be understood that the word "if," as used herein, may be interpreted as "at … …" or "when … …" or "in response to a determination," depending on the context.
The method aims to provide a technical scheme for distinguishing whether the interface state in the interface state synchronization group is actively changed due to the change of a network connected with the interface or passively changed due to the change of other interface states by setting a master state and a slave state for the interface in the interface state synchronization group.
In implementation, please refer to fig. 1, where fig. 1 is a flowchart of an interface state synchronization method shown in the present application.
The method is applied to the network equipment. The plurality of interfaces of the network device are configured as an interface state synchronization group; the interface in the interface state synchronization group comprises a master state and a slave state.
The method comprises the following steps:
s101, determining whether the network connected with each interface in the interface state synchronization group has state change;
s102, if the state of the network connected with any target interface in the interface state synchronization group changes, updating the main state of the target interface to the interface state corresponding to the network state after the state of the network changes;
and S103, updating the slave states of the interfaces except the target interface in the interface state synchronization group to the interface states respectively.
As can be seen from the above-described technical solutions, when a network connected to any one of the interfaces in the interface state synchronization group changes, the master state of the interface is updated to an interface state corresponding to the network state after the network state changes, and the slave states of the interfaces other than the target interface in the interface state synchronization group are updated to the interface states, so that it is possible to distinguish whether the interface state in the interface state synchronization group is actively changed due to a change in the network connected to the interface or passively changed due to a change in the other interface states.
The technical means described in the present application will be described below with reference to specific examples.
Referring to fig. 2, fig. 2 is a network device networking diagram shown in the present application. As shown in fig. 2, the network device 1 (hereinafter referred to as device 1) may include an interface A, B, C, and the three interfaces may be in the same interface state synchronization group. The device 1 can be communicatively connected to a network device 2 (hereinafter referred to as device 2) and a network device 3 (hereinafter referred to as device 3) through an interface B and an interface C, respectively. The device 1 is connected to the network via an interface a.
It should be noted that the network may be composed of a plurality of network devices and links connecting the network devices, and represents a plurality of objects and their interconnections, and the structure of the network is not particularly limited herein. The network failure described in the present application may refer to a situation where the network is disconnected, for example, one or several network devices in the network fail, or a link fails to break, and the like, which is not limited herein. In addition, those skilled in the art will understand that the type of network device illustrated in fig. 2 is merely illustrative, and the network device in this application may be a switch, a router, a firewall gateway, etc., and is not limited herein.
In the above situation, since the interface A, B, C is in the same interface state synchronization group, if any one of the interfaces has a state change, each of the other interfaces will change its own interface state to automatically synchronize the interface states in the same interface state synchronization group.
It should be noted that the interface states of the above interface may include UP and DOWN (where UP may indicate a normal state and DOWN may indicate a fault state); the state change of any interface can be caused by the change of the working state of the interface hardware or the change of the network state of the network connected with the interface.
In the illustrated embodiment of the present application, the interface A, B, C has a master state and a slave state. Any one of the master state and the slave state is DOWN, and the interface state can be indicated as DOWN; the master state and the slave state are both UP, which may indicate that the interface state is UP.
In an embodiment, the master state, the slave state and the interface index may be stored in the network device in a form of a linked list. For example, the master state information and the slave state information of a certain interface and the unique identification information of the interface are hung in the use linked list as a linked list node.
It should be noted that, each node (state information of each interface) of the above-mentioned linked list is scattered in the memory due to independent application of memory space, and therefore, when setting the state of each interface, CACHE MISS (where CACHE refers to the CACHE of the CPU, data is obtained from the CACHE when the CPU runs, and if the required data is not on the CACHE, the data on the CACHE needs to be swapped out, the required data is swapped in the CACHE, and then the required data is obtained from the CACHE; CACHE MISS refers to that the CPU does not find the data needed to be used on the CACHE), and thus, the speed of setting the state of each interface (updating the master and slave state information of the interface) is slow.
In order to increase the speed of setting the states of the interfaces, in one embodiment, the master state, the slave state, and the interface index may be stored in the network device in the form of a structure array. For example, the master status information and the slave status information of a certain interface and the unique identification information of the interface are stored as a structure element in a section of structure array applied in advance.
Specifically, in order to ensure that the structure arrays are stored continuously, a memory space with a specified size may be allocated in the memory for the interface state synchronization group in the form of a structure array, each structure represents an interface in the interface state synchronization group, and the structure has master state information and slave state information of the interface and unique identification information of the interface. Because the storage space of the structure array is continuous, CACHE MISS can not occur when setting the state of each interface (updating the master and slave state information of the interface), thereby greatly improving the speed of setting the state of each interface.
In the scenario as shown in fig. 2, a memory space of 16 interface structure bodies may be allocated in advance in the memory in the form of a structure body array for the interface state synchronization group. Interface A, interface B, interface C can be stored in the above-mentioned structure array. For example, the interface A, B, C is stored in the first three locations of the array of structures, and all other locations are set to 0.
S101, determining whether the state of the network connected with each interface in the interface state synchronization group changes;
in an embodiment, the interface of the device 1 may monitor itself the network status of the network to which it is connected. For example, the interface of the device 1 may interact with the peer interface through a specific protocol to confirm that the network between the two is in a normal state. In this embodiment, if the interface of the device 1 does not receive a response from the peer interface within the preset time period, it may be considered that the network fails, that is, it may be considered that the network state of the network changes from normal to failure; at this time, if the interface of the device 1 can continue to interact with the opposite-end interface through the specific protocol, it may be considered that the network is recovered to be normal, that is, it may be considered that the network state of the network is recovered from the failure to be normal.
S102, if the state of the network connected with any target interface in the interface state synchronization group changes, updating the main state of the target interface to the interface state corresponding to the network state after the state of the network changes;
in an embodiment, if any interface of the device 1 confirms that the network connected to the interface has a status change, the interface may send the information of the status change (including the interface index information and the network status information after the status change) to the CPU of the device 1. After the CPU obtains the information, the CPU may update the master status of the interface to an interface status corresponding to a network status after the status of the network has changed.
For example, when the interface a of the device 1 detects that the network state of the network connected thereto changes from normal to failure, the interface sends the information that the interface identifier a of the interface itself and the network state are failure to the CPU. After the CPU obtains the information, the CPU can traverse each structural body in the structural body array, and update the main state of the structural body with the index mark A to DOWM.
Here, it is understood that when the interface a detects that the network state of the network connected thereto is recovered from the failure to be normal, the network device will perform similar steps as described above, and will not be described in detail herein.
And S103, updating the slave states of the interfaces except the target interface in the interface state synchronization group to the interface states respectively.
In an embodiment, if any interface of the device 1 confirms that the network connected to the interface has a status change, the interface may send the information of the status change (including the interface index and the network status information after the status change) to the CPU of the device 1. The CPU may update the slave status of each interface other than the interface to the interface status corresponding to the network status after the status change of the network after acquiring the information.
For example, when the interface a of the device 1 detects that the network state of the network connected thereto changes from normal to failure, the interface sends the information that the interface identifier a of the interface and the network state are failure to the CPU. After acquiring the information, the CPU may traverse each structure in the structure array, and update the slave state of the structure with the index identifiers other than a (in this embodiment, the index identifiers are B and C) to DOWM. Here, it is understood that when the interface a detects that the network state of the network connected thereto is recovered from the failure to be normal, the network device will perform similar steps as described above, and will not be described in detail herein.
It should be noted that, the method for synchronizing the states of each interface after the interface hardware fails is the same as the method for synchronizing the states of each interface after the network connected to the interface fails, and is not described herein again.
As can be seen from the above-described technical solutions, when a network connected to any one of the interfaces in the interface state synchronization group changes, the master state of the interface is updated to an interface state corresponding to the network state after the network state changes, and the slave states of the interfaces other than the target interface in the interface state synchronization group are updated to the interface states, so that it is possible to distinguish whether the interface state in the interface state synchronization group is actively changed due to a change in the network connected to the interface or passively changed due to a change in the other interface states.
In an embodiment shown in the present application, a method of indicating an interface state corresponding to a slave state by a count value is proposed; when the counting value is a first preset value, the interface state corresponding to the slave state is a normal state; and when the counting value is not a first preset value, the interface state corresponding to the slave state is a fault state.
If the network state of any interface connection in the interface state synchronization group is changed from normal to fault, increasing the count value in the slave state of each interface except the interface in the interface state synchronization group by a second preset value;
and if the network state of any interface connection in the interface state synchronization group is changed from fault to normal, reducing the count value in the slave state of each interface except the interface in the interface state synchronization group by the second preset value.
Here, it should be noted that, in this embodiment, the master state of the interface may indicate the corresponding interface state through a count value, or may indicate the corresponding interface state through another method, which is not limited herein. The following description will take an example in which the master status of the interface also indicates the corresponding interface status through the count value, and the first preset value is 0 and the second preset value is 1.
Referring to fig. 3a, fig. 3a is a schematic diagram of an array of structures shown in the present application.
As shown in fig. 3a, when the link in which the device 1 is located is in the normal operating state, the master state and the slave state of the interface A, B, C are both UP, that is, the interface A, B, C is both in the UP state. This is consistent with the actual state of each interface described above.
If the interface A monitors that the network state of the network connected with the interface A is changed from normal to fault, the interface sends the information that the self interface identification A and the network state are fault to the CPU. After the CPU obtains the information, it may traverse each structure in the structure array, and increment a count value in the master state of the structure having an index identifier a by one, and increment a count value in the slave state of the structures having index identifiers B and C by one. Specifically, referring to fig. 3b, fig. 3b is a schematic diagram of a structure array shown in the present application.
As shown in fig. 3b, the master state of interface a is 1 and the slave state is 0; the master state and the slave state of the interface B and the interface C are respectively 0 and 1; indicating that interface a is actively changing to the DOWN state due to a change in the network to which it is connected, and that interface B, C is passively changing to the DOWN state due to a change in the state of the other interfaces. This is consistent with the above-described actual situation of interface state change of each interface.
Under the above situation, if the interface B monitors that the network status of the network connected to the interface B is also changed from normal to failure (in this application, the device 2 may have a hardware or network failure), the interface B will send the information that the own interface identifier B and the network status are failure to the CPU. After the CPU obtains the information, it may traverse each structure in the structure array, and increment a count value in the master state of the structure having an index id B by one, and increment a count value in the slave state of the structures having index ids a and C by one. Specifically, referring to fig. 3c, fig. 3c is a schematic diagram of a structure array shown in the present application.
As shown in fig. 3c, the master state of the interface A, B is 1, and the slave state is 1; the state of the interface C is 0, and the slave state is 2; i.e. to indicate that interface a and interface B need to change to DOWN either actively due to a change in the network to which the interface is connected or else due to a change in the state of the other interface, while interface C is passively changed to DOWN due to a change in the state of the other interface. This is consistent with the above-described actual situation of interface state change of each interface.
In the above situation, if the interface a detects that the network state of the network connected thereto is recovered from the failure to normal, the count value in the master state of the interface a is decreased by one, and the slave states of the interface B and the interface C are decreased by one. Specifically, referring to fig. 3d, fig. 3d is a schematic diagram of a structure array shown in the present application.
As shown in fig. 3d, the master state of the interface A, C is 0 and the slave state is 1; the master state of the interface B is 1, and the slave state of the interface B is 0; indicating that interface B is actively changing to the DOWN state due to a change in the network to which it is connected, and that interface A, C is passively changing to the DOWN state due to a change in the state of the other interfaces. This is consistent with the above-described actual situation of interface state change of each interface.
In the above situation, if the interface B detects that the network status of the network connected to the interface B is recovered from the failure to normal, the count value in the master status of the interface B is decreased by one, and the slave statuses of the interface a and the interface C are decreased by one. Specifically, referring to fig. 3e, fig. 3e is a schematic diagram of a structure array shown in the present application.
As shown in fig. 3e, the master state of the interface A, B, C is 0, and the slave states are both 0; i.e., indicating that the interface A, B, C is in an UP state. This is consistent with the actual state of each interface described above.
In an embodiment shown in the present application, the number of interfaces with network faults in the interface state synchronization group to which the interface belongs may also be obtained from the count value of the state record through any interface.
In practical application, a value obtained by subtracting a first preset value from a count value of a slave state of the target interface and then dividing the value by a second preset value is calculated and is output as the number of interfaces which are connected in the interface state synchronization group and have faults except the target interface; wherein the second preset value is not 0.
For example, as shown in fig. 3C, the interface C counts the value 2 from the state, the first preset value is 0, and the second preset value is 1. The numerical value 2 can be obtained after the calculation of the steps, so that the two interfaces except the target interface in the interface state synchronization group have network faults. This is consistent with the actual state of each interface described above.
As can be seen from the above description of the solution, the present application is a method for indicating the interface state corresponding to the slave state by the count value; when the counting value is a first preset value, the interface state corresponding to the slave state is a normal state; when the counting value is not a first preset value, the interface state corresponding to the slave state is a fault state; if the network state of any interface connection in the interface state synchronization group is changed from normal to fault, updating the main state of the interface to the interface state corresponding to the network state after the state change of the network, and increasing the count value in the slave state of each interface except the interface in the interface state synchronization group by a second preset value; if the network state of any interface connection in the interface state synchronization group is changed from fault to normal, updating the main state of the interface to the interface state corresponding to the network state after the state change of the network, and reducing the count value in the slave state of each interface except the interface in the interface state synchronization group by the second preset value; therefore, the interface state change situation of the interface indicated by the master state and the slave state of the interface in the structure body is consistent with the actual interface state change situation of the interface in the interface state synchronization group, so that the interface state of each interface in the interface state synchronization group is ensured to be represented as the actual state of a network connected with each interface.
Corresponding to the above method embodiment, the present application further provides an interface state synchronization apparatus, which is applied to a network device. A plurality of interfaces of the network device are configured as an interface state synchronization group; the interface in the interface state synchronization group comprises a master state and a slave state.
