Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Fig. 1 is a block diagram of a network device 10 according to a preferred embodiment of the present invention. In this embodiment, the network device 10 is configured to perform data communication, and the network device 10 includes a plurality of backup groups 13, where each backup group 13 includes a main board 131 and a backup board 132. The main board 131 includes a main session entry, and the standby board 132 is configured to backup the main session entry in the corresponding main board 131.
In this embodiment, the main board 131 may individually correspond to one standby board 132, so as to form one backup group 13 by combining with the standby board 132, in which case all the main session entries on the main board 131 are main session entries corresponding to the backup group 13; the main board 131 in the network device 10 may also correspond to a plurality of standby boards 132, and combine with each standby board 132 to form a backup group 13, in this case, the main session entries corresponding to the main board 131 in the backup groups 13 including the same main board 131 may be different. For example, the network device 10 shown in fig. 1 includes three backup groups 13, which are backup group a1 consisting of motherboard a and backup board a1, backup group a2 consisting of motherboard a and backup board a2, and backup group B consisting of motherboard B and backup board B. The standby board B is used for backing up the main session table entry in the main board B, the standby board a1 is used for backing up the main session table entry corresponding to the backup group a1 in the main board a, and the standby board a2 is used for backing up the main session table entry corresponding to the backup group a2 in the main board a.
In this embodiment, the network device 10 may forward, based on the session entry corresponding to each backup group 13 in the main board 131 or the standby board 132, the packet traffic correspondingly matched with the session entry, so as to implement the data communication function of the network device 10. When each data flow passes through the network device 10 for the first time, the network device 10 creates a main session entry matched with the data flow in the main board 131 corresponding to the corresponding backup group 13 according to the traffic information of the data flow. If the subsequent message traffic flowing into the network device 10 matches the master session entry, the network device 10 may directly forward the message traffic based on the master session entry, where the master session entry is a session entry created on the motherboard 131. The network device 10 may send the main session entry on each main board 131 to the standby board 132 corresponding to the backup group 13 for storage and backup, so as to ensure that the standby board 132 in each backup group 13 can provide the session entry matching with the current data traffic when the corresponding main board 131 is damaged, thereby ensuring that the existing connection information in the network device 10 is not lost due to link switching, and ensuring that the network device 10 can continuously and stably operate.

In this embodiment of the present application, after the main board 131 creates a main session entry matched with the corresponding backup group 13, the main session entry is stored, where a storage form of the main session entry in the main board 131 may be, but is not limited to, a linked list, a table, a list, or the like. In order to more clearly illustrate the technical solution of the embodiment of the present application, a table entry chain table is taken as an example of a storage form of the main session table entry, and a detailed description is given to an implementation manner of the embodiment of the present application.
It should be understood that the form of storing the list table entry is only one embodiment of the present application, and should not be construed as a limitation to the scope of the present application. Optionally, the main board 131 may store the created main session entries in a form of an entry chain table, where the main session entries are sequentially stored in the corresponding entry chain table according to the creation time sequence, and if the main board 131 is shared by a plurality of backup groups 13, the number of the entry chain tables in the main board 131 is the same as the total number of the corresponding backup groups 13, and each entry chain table individually corresponds to one backup group 13, so that the main session entries of the corresponding backup groups 13 are stored by each entry chain table. For example, as shown in fig. 2, a backup group a1 formed by a main board a and a backup board a1, a backup group a2 formed by a main board a and a backup board a2, where the main board a is a main board 131 shared by the backup group a1 and the backup group a2, two table entry chain tables exist in the main board a, one is a table entry chain table a1 corresponding to the backup group a1, and the other is a table entry chain table a2 corresponding to the backup group a2, the main board a stores a main session table entry corresponding to the backup group a1 through the table entry chain table a1, and the main board a stores a main session table entry corresponding to the backup group a2 through the table entry chain table a 2. The standby board A1 comprises an item linked list a-1, wherein the item linked list a-1 is used for backing up a main session item in the item linked list a 1; backup board A2 includes an entry chain table a-2, where entry chain table a-2 is used to backup the primary session entry in entry chain table a 2.
Optionally, please refer to fig. 3, which is a flowchart illustrating an entry processing method according to a preferred embodiment of the present application. In this embodiment of the present application, the entry processing method is applied to the main board 131 shown in fig. 1, where the main board 131 belongs to at least one backup group 13, and the main board 131 may perform equalization processing on session entries corresponding to each backup group 13 including the main board 131 in time by using the entry processing method, so as to improve the operation stability of the network device 10. The detailed flow and steps of the table entry processing method shown in fig. 3 are described in detail below.
In an embodiment of the present application, the entry processing method includes the following steps:
step S310, obtain the entry information of the main session entry corresponding to each backup group 13 of the motherboard 131.
In this embodiment, the main board 131 obtains the entry information of the main session entry on the main board 131 by monitoring the change condition of the main session entry in each entry linked list in the time period between two times of timeout of the timer, that is, the entry information of the main session entry corresponding to each backup group 13 of the main board 131 on the main board 131. Wherein the change condition comprises: the number of main session entries deleted when the last timer corresponding to each entry linked list in the motherboard 131 times out, the number of main session entries newly built before the timeout of the current timer corresponding to each entry linked list in the motherboard 131, the number of session entries which are not backed up when the current timer corresponding to each entry linked list in the motherboard 131 times out, and the like.
Step S320, according to the entry information of each main session entry, allocating a corresponding number of tokens for processing the entry to each main session entry.
In this embodiment, the motherboard 131 may periodically place a certain number of tokens into a token bucket included in the motherboard 131 to ensure that the number of available tokens in the token bucket remains constant. After obtaining the entry information of the master session entry in the corresponding entry linked list corresponding to the backup group 13, the main board 131 may allocate tokens, the number of which is matched with that of the corresponding entry information, to the master session entries on the main board 131 of each backup group 13 from the token bucket, and process the master session entries matched on the main board 131 through the allocated tokens.
In this embodiment, the greater the number of entries of the main session entry corresponding to each backup group 13 on the main board 131, the greater the number of entries that need to be processed by the corresponding backup group 13. In different backup groups 13 sharing the same motherboard 131, some of the session entries corresponding to the backup groups 13 are in a state of being continuously created and deleted, and some of the backup groups 13 have a larger number of session entries, but most of the session entries are in a stable state, in which case the backup group 13 with a high entry change activity level should acquire more tokens. Therefore, when the timer expires to allocate a token to the main session entry corresponding to each backup group 13, the main board 131 needs to comprehensively consider the above factors, so as to ensure that the main board 131 can perform balanced processing on the session entries corresponding to each backup group 13, and improve the operation stability of the corresponding network device 10.
Optionally, please refer to fig. 4, which is a flowchart illustrating the sub-steps included in step S320 shown in fig. 3. In an implementation manner of the embodiment of the present application, the entry information includes an entry number and an entry change activity of each master session entry when the current timer is overtime, where the entry number refers to a number of each master session entry retained in a corresponding entry linked list of the corresponding motherboard 131, and the entry change activity refers to a number change amplitude of each master session entry in a time period between two adjacent times of timer overtime of the corresponding motherboard 131. Wherein the specific value of the entry change activity is the sum of the number of entries deleted by the last timer when the corresponding main session entry is overtime and the number of entries newly added before the current timer is overtime, then step S320 may include substep S321 and substep S322, where substep S321 and substep S322 are as follows.
And a substep S321, obtaining the table item ratio of the table item number corresponding to the main session table item in the total table item number of all main session table items and the activity ratio of the table item change activity of the corresponding main session table item in the total table item change activity number of all main session table items according to the table item number and the table item change activity of each main session table item.
In this embodiment, the main board 131 may perform a summation operation on the number of entries of the main session entry in each entry linked list of the main board 131 to obtain the total number of entries of all main session entries of the main board 131 in the current timer, and the main board 131 calculates the entry proportion of the number of entries of each main session entry in the total number of entries of all main session entries on the main board 131 based on the total number of entries and the number of entries of the main session entry in the corresponding entry linked list.
The main board 131 may perform summation operation on the table entry change activity of the main session table entry in each table entry chain table of the main board 131 to obtain a total table entry change activity of all session table entries of the main board 131 when the current timer is overtime, and the main board 131 calculates an activity ratio of the table entry change activity of each main session table entry in the total table entry change activity of all main session table entries on the main board 131 based on the total table entry change activity and the table entry change activity of the main session table entry in the corresponding table entry chain table.
And a substep S322, distributing a corresponding amount of aging deletion tokens for each main session table entry according to the table entry proportion and the activity proportion of each main session table entry.
In this embodiment, the main board 131 may allocate aging deletion tokens, which are used for performing aging deletion and have a number matching with that of the main session entries, from the aging deletion token bucket according to the entry proportion and the activity proportion of the main session entries in the main board 131 corresponding to the backup group 13. The number of the aging deletion tokens correspondingly distributed to each main session entry is distributed according to a token distribution proportion, and the token distribution proportion is obtained by calculating the entry proportion, the activity proportion and the distribution proportion between the entry proportion and the activity proportion of each main session entry. Specifically, the allocation percentage includes a first percentage corresponding to the entry percentage and a second percentage corresponding to the activity percentage, where a sum of the first percentage and the second percentage is 100%, and specific values of the first percentage and the second percentage may be configured differently according to a balance state between the number of entries and the entry change activity level of each main session entry in the motherboard 131 when the main session entry is aged and deleted.
In this embodiment, first, the main board 131 obtains a first ratio by multiplying the table entry proportion corresponding to the main session table entry by the first ratio, then obtains a second ratio by multiplying the activity proportion of the main session table entry by the second ratio, and finally obtains a token allocation proportion corresponding to the main session table entry by adding the first ratio and the second ratio.
In this embodiment, after obtaining the token allocation proportion corresponding to the main session entry stored in the own entry linked list, the main board 131 performs multiplication operation on the total number of available tokens in the aging deletion token bucket and the token allocation proportion corresponding to the main session entry, correspondingly obtains the number of assignable tokens for the corresponding main session entry in the aging deletion token allocation process, and assigns the aging deletion token for the main session entry of the corresponding backup group 13 from the aging deletion token bucket according to the number of assignable tokens for the corresponding main session entry.
Fig. 5 is a schematic view of another flow chart of the sub-steps included in step S320 shown in fig. 3. In another implementation manner of the embodiment of the present application, the entry information includes a number of unrepaired entries of each main session entry in a timeout of the current timer, where the number of unrepaired entries refers to a number of entries, which are not backed up by the corresponding standby board 132, of each main session entry retained in the corresponding entry linked list of the corresponding main board 131, then step S320 may include substep S323 and substep S324, where substep S323 and substep S324 are shown as follows.
And a substep S323, obtaining the non-backup ratio of the number of the non-backup table entries of the corresponding main session table entries in the total number of the non-backup table entries of all the main session table entries according to the number of the non-backup table entries of each main session table entry.
In this embodiment, the main board 131 may perform a summation operation on the number of unrepaired entries of the master session entries in each entry linked list of the main board 131 to obtain the total number of unrepaired entries of all master session entries of the main board 131 when the current timer is overtime, and the main board 131 calculates, based on the total number of the unrepaired entries and the number of unrepaired entries of each master session entry on the main board 131, an unrepaired occupancy of the number of unrepaired entries of each master session entry on the main board 131 in the total number of the unrepaired entries of all master session entries.
And a substep S324, allocating a corresponding number of backup tokens to each main session entry according to the non-backup percentage of each main session entry.
In this embodiment, after obtaining the non-backup percentage of the master session entry stored in each entry chain table of the master board 131, the master board 131 may allocate backup tokens for the backup entries, the number of which is matched with that of the corresponding master session entries, from the backup token bucket according to the non-backup percentage of each master session entry of the master board 131. The main board 131 obtains the number of allocable tokens of the corresponding main session entry in the process of allocating the backup tokens by multiplying the total number of the available tokens in the backup token bucket by the non-backup percentage of each main session entry, and allocates the backup tokens to the main session entries of the corresponding backup group 13 from the backup token bucket according to the number of the allocable tokens of each main session entry, where the backup tokens are used to backup the session entries.
In this embodiment of the present application, the motherboard 131 may allocate a corresponding number of aging deletion tokens to the corresponding main session entry according to the token allocation manner of the above sub-step S321 and sub-step S322 when the current timer is overtime, and allocate a corresponding number of backup tokens to the corresponding main session entry according to the token allocation manner of the above sub-step S323 and sub-step S324 when the next timer is overtime; or distributing a corresponding number of backup tokens to the corresponding main session entry when the current timer is overtime according to the token distribution mode of the substep S323 and the substep S324, and distributing a corresponding number of aging deletion tokens to the corresponding main session entry when the next timer is overtime according to the token distribution mode of the substep S321 and the substep S322; when the current timer is overtime, the corresponding backup tokens and the aged deletion tokens can be allocated to the corresponding main session entry according to the token allocation mode of the substep S323 and the substep S324 and then according to the token allocation mode of the substep S321 and the substep S322. Wherein, the specific token allocation scheme can be configured according to actual requirements.
Referring to fig. 3 again, in step S330, each main session entry is processed according to the allocated token, and the session entries backed up in the standby board 132 of the corresponding backup group 13 are updated based on each processed main session entry.
In this embodiment of the present application, after the main board 131 allocates the corresponding token for the corresponding main session entry, different session entry processing schemes may be executed according to different token allocation manners, and balanced aging deletion and/or balanced backup may be uniformly performed on the main session entries of at least one backup group 13 corresponding to the main board 131, so that the session entries that need to be aged and deleted in each main session entry of the main board 131 may be aged and deleted in time, so as to ensure that the rate of aging and deleting the session entries of the main board 131 is faster; the session entries to be backed up in each main session entry of the motherboard 131 can be backed up in time, so as to ensure that the backup rate of the session entries of the motherboard 131 is high, and thus the session entries to be processed in each main session entry of the motherboard 131 are processed in time, and the operation stability of the network device 10 is improved.
Optionally, please refer to fig. 6, which is a flowchart illustrating the sub-steps included in step S330 shown in fig. 3. In this embodiment of the application, if the way that the main board 131 allocates the token to each main session entry is the way that the sub-step S321 and the sub-step S322 shown in fig. 4 correspond to, the token allocated to each main session entry is an aging deletion token, the step S330 may include the sub-step S331 and the sub-step S332, and the sub-step S331 and the sub-step S332 are as follows.

Specifically, the motherboard 131 may allocate, by performing steps similar to the sub-step S321 and the sub-step S322, a corresponding number of aging detection tokens for aging detection from an aging detection token bucket to each main session entry in the motherboard 131, where a total number of tokens in the aging detection token bucket is not less than a total number of tokens in the aging deletion token bucket.
In another implementation manner in this embodiment, the main board 131 may perform aging detection on the master session entry in the corresponding entry linked list by polling each entry linked list, and stop the corresponding aging detection when the aging deletion token allocated to the corresponding master session entry is used up.
