Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to solve the above-mentioned technical problem, it an embodiment of the present invention provides a kind of link list item synchronous method, device and sets
It is standby.This method and device are applied to the network equipment, which can be gateway, router, interchanger, load-balancing device
Etc., it does not limit specifically.The network equipment includes multiple business boards, may include in multiple business board main business plate and
Standby business board.
Link list item synchronous method provided in an embodiment of the present invention is described in detail first below.
Fig. 1 is a kind of flow diagram of link list item synchronous method provided in an embodiment of the present invention, is included the following steps.
S101：Standby business board sends a notification message to main business plate.
For example, standby business board can send a notification message to main business plate immediately upon actuation.Alternatively, standby business board
Self-operating state can also be monitored, when itself is in non-busy condition, is sent a notification message to main business plate.For example, standby
Business board can obtain the occupancy of itself chip, when the occupancy is less than given threshold, indicate that standby business board is in non-busy
Commonplace state.
For example, notification message can be based on UDP (User Datagram Protocol, User Datagram Protocol)
Message packet, alternatively, can also be other self-defined message bodies, concrete structure does not limit.
S102：Main business plate is sent to this for business board after receiving the notification message, by the link list item of generation.
May include one or more standby business boards in the network equipment, if the network equipment includes multiple standby business boards,
The link list item of generation is sent to the standby business board to send a notification message by main business plate.As an example it is assumed that in the network equipment
Including multiple standby business boards：Standby business board A, standby business board B, standby business board C, main business plate receive what standby business board B was sent
Notification message, then main business plate the link list item of generation is sent to standby business board B.
In the present embodiment, after main business plate generates link list item, the link list item of generation standby industry is not sent to immediately
Business plate；As an implementation, after main business plate generates link list item, can the link list item of generation be first added to synchronization
In queue, after main business plate receives the notification message that standby business board is sent, main business plate obtains chain from the isochronous queue
Road list item, and acquired link list item is sent to this for business board.
In the case of one kind, after receiving the notification message that standby business board is sent, main business plate can pass through main business plate
It repeatedly shakes hands and establishes session link with standby business board.Alternatively, session link can not also be established, main business plate receives the notice
Message indicates that main business plate can carry out data interaction with standby business board, and this is also rational.
As an implementation, S102 may include：Main business plate determine between main business plate and standby business board can
With bandwidth, and determine according to the available bandwidth data volume of the link list item sent；The main business plate is according to the data
Amount, to the standby business board transmission link list item.
Specifically, main business plate can obtain the total bandwidth between main business plate and standby business board, and determine main business
Bandwidth has been used between plate and standby business board；Main business plate is by the total bandwidth and the difference for having used bandwidth, as current
Available bandwidth between business board；Main business plate determines the byte value for any bar link list item that the link list item includes,
The quotient for calculating the available bandwidth and the byte value determines the list item quantity sent in the unit interval according to the quotient；Main business
Plate be engaged according to determining list item quantity, the quantity link list item is sent to standby business board.
For example, usually, the total bandwidth between main business plate and standby business board is the hardware by the network equipment
It can determine, which may be considered a fixed value, can include the total bandwidth, main business in the product parameters of the network equipment
Business plate can obtain the total bandwidth by reading the product parameters.In addition, main business plate can according to main business plate with it is each standby
Interaction data amount between business board determines the bandwidth currently used up, that is, this has used bandwidth.Total bandwidth and bandwidth is used
Difference be available bandwidth between current business plate.
The usual difference of byte value of each of the links list item is little, it is believed that the byte value of wherein one link list item can be with
The byte value size of other link list items is represented, the quotient of " available bandwidth " and " byte value of any bar link list item " is calculated.One
It, can be using obtained quotient as the list item quantity sent in the unit interval, in another case, can will obtain in the case of kind
Quotient is multiplied with a threshold value, using obtained product as the list item quantity sent in the unit interval.The threshold value can be 0.6,0.7,
Or any value between 0.6-0.7, the concrete numerical value of the threshold value do not limit.
Main business plate can be according to the list item quantity being calculated, to standby business board transmission link list item；In other words, main
When business board is to standby business board transmission link list item, the quantity link list item is sent in each unit interval.In this way, being unlikely to
Bandwidth between extra plate is wasted, while the transmission of business datum between other plates of bandwidth contributions between too many plate will not be occupied.
In existing scheme, main business is sent to standby business board data volume in the plate unit interval is a fixed value, in this way, such as
The fruit data volume is a smaller value, and available bandwidth is larger between each business board in the network equipment, then cannot make full use of this can
With bandwidth, bandwidth is not only wasted, but also reduces link list item synchronizing speed；If the data volume is a higher value, and network is set
Available bandwidth is smaller between each business board in standby, and it will cause network congestions, reduce the treatment effeciency of the network equipment.
And in present embodiment, it can be standby to being sent in the main business plate unit interval according to actual bandwidth service condition
The data volume of business board is adjusted, and scheme is flexible, more reasonable to the use of bandwidth.
S103：Standby business board stores the link list item to this for business board.
After standby business board receives the link list item of main business plate transmission, which is stored to itself, in this way, just
Link list item is completed in the synchronization for business board.
As an implementation, standby business board stores link list item to after itself, can be sent to main business plate
Synchronize successful message.In a kind of above-mentioned embodiment, link list item has been added in isochronous queue by main business plate, this reality
Apply in mode, after main business plate synchronizes successful message receive that standby business board sends, can by isochronous queue should
Link table entry deletion.
In the case of one kind, if there are multilink list item in isochronous queue, can by identification information pair this plurality of chain
Road list item distinguishes, the identification information can be ID or be the version information of list item or be list item generated time
Deng not limiting specifically.In this case, what standby business board was sent, which synchronize to carry in successful message, synchronizes successful chain
The mark of road list item, main business plate receive after this synchronizes successful message, by the corresponding link list item of the mark from synchronous team
It is deleted in row.
In existing scheme, after standby business board receives the link list item of main business plate transmission, does not send usually and synchronize success
Message.In this way, main business plate does not know that whether link table item synchronizes success, it also cannot be to the link table of synchronization failure
Item retransmits, and the validity of synchronization link list item is poor.And in present embodiment, standby business board stores link list item
Afterwards, successful message is synchronized to the transmission of main business plate.In this way, main business plate can understand whether link list item synchronizes success, into
And the link list item of synchronization failure is retransmitted, improve the validity of synchronization link list item.
And if main business plate after sending the first preset duration of the link list item to standby business board, does not receive this
What standby business board was sent synchronizes successful message, which can be added in explorer queue by main business plate.A kind of feelings
Under condition, which can be moved to from isochronous queue in explorer queue by main business plate, that is to say, that in isochronous queue
It is middle by the link table entry deletion；In another case, the link list item can be copied to spy by main business plate from isochronous queue
It surveys in queue, that is to say, that not by the link table entry deletion in isochronous queue.
After link list item is added to explorer queue by main business plate, starts timing, determine the link list item in explorer queue
In there are durations.Monitoring this, there are durations whether to reach default detection duration, if reached, main business plate is first to standby business board
Probe messages are sent, if main business plate receives the detection response message that standby business board is sent, main business plate is again to standby
Business board sends the link list item.
Successfully disappear if main business plate after sending the link list item again, receives standby synchronizing for business board transmission
Breath, then main business plate is by the link table entry deletion in explorer queue；If main business plate is sending the link list item again
Do not receive that standby business board sends in second preset duration synchronizes successful message, then by the link list item there are when Changqing
Zero, and restart timing, determine the link list item in explorer queue there are durations, and in the presence of this it is long reach it is default
In the case of detecting duration, probe messages are sent to the standby business board.
Second preset duration may be the same or different with the first preset duration, not limit specifically.When default detection
Length can rule of thumb be set, and the embodiment of the present application does not limit.
In a kind of embodiment, for the link list item in isochronous queue, if sending failure, can repeatedly it send out
It send, if after transmission N (i.e. predetermined threshold value) is secondary, does not send yet successfully, then the link list item is added in explorer queue.Its
In, N is positive integer.
Specifically, if main business plate does not receive standby business board in the first preset duration for sending the link list item and sends out
That send synchronizes successful message, then main business plate can retransmit the link list item in isochronous queue.When first
The number for synchronizing successful message and retransmitting the link list item is not received in preset duration and is less than predetermined threshold value
When, it repeats and the link list item in the isochronous queue is retransmitted, until being received in the first preset duration
The number for synchronizing successful message or retransmitting the link list item that the standby business board is sent is equal to the default threshold
Value.
Wherein, described when receiving that the standby business board sends in the first preset duration when synchronizing successful message
Main business plate deletes the link list item from the isochronous queue, and stops the retransmission to the link list item；When
When retransmitting the number of the link list item and reaching predetermined threshold value, the main business plate is by the link list item from the synchronization
It is deleted in queue, and executes the step being added to the link list item in explorer queue.
For example, if main business plate do not received in the first preset duration of transmission link list item the synchronization at
The message of work(, then main business plate can once retransmit the link list item with every preset time period, until main business
After what plate received that standby business board sends synchronizes successful message, main business plate deletes the link list item from isochronous queue,
And retransmission of the stopping to the link list item.
And if main business plate does not receive synchronize successful message for what business board was sent always, when main business plate is to this
When the number that link list item retransmits reaches predetermined threshold value, main business plate deletes the link list item from isochronous queue, and
The link list item is added in explorer queue.
As described above, the newly-generated link list item of main business plate can be also added in isochronous queue, that is to say, that this implementation
Both there is newly-generated link list item in mode, in isochronous queue, there is also multiple send is not successfully transmitted yet to standby business board
Link list item；In the case of one kind, it can be marked to repeatedly sending the link list item not being successfully transmitted yet, main business plate is excellent
First send the link list item that there is label in isochronous queue.
Alternatively, in another case, main business plate can set the priority of all link list items in isochronous queue, it is newborn
The priority that repeatedly transmission is not successfully transmitted link list item yet can be less than at the priority of link list item, this is also rational.
If the network equipment includes a main business plate and multiple standby business boards, main business plate can be directed to each standby
Business board safeguards an isochronous queue and an explorer queue.If the network equipment includes multiple main business plates and multiple standby industry
It is engaged in plate, then a main business plate can correspond to one or more standby business boards, and for each main business plate, it can be directed to
Its corresponding each standby business board safeguards an isochronous queue and an explorer queue respectively.
As an example it is assumed that there are a main business plate A and two standby business boards in the network equipment：Standby business board A1 and standby
Business board A2.Main business plate A safeguards two isochronous queues：Isochronous queue 1 and isochronous queue 2, wherein isochronous queue 1 be for
The isochronous queue that standby business board A1 is established, isochronous queue 2 are the isochronous queue established for standby business board A2.Main business plate A dimensions
Protect two explorer queues：Explorer queue 1 and explorer queue 2, wherein explorer queue 1 is the detection established for standby business board A1
Queue, explorer queue 2 are the explorer queue established for standby business board A2.
After main business plate A generates link list item, the link list item of generation is added separately in two isochronous queues.Assuming that
Standby business board A1 sends a notification message to main business plate, after main business plate receives the notification message, is obtained from isochronous queue 1
Link list item, and acquired link list item is sent to standby business board A1.
If standby business board A1 receives the link list item, standby business board A1 stores the link list item to itself, and to
The A transmissions of main business plate synchronize successful message.Main business plate A is received after this synchronizes successful message, by the link list item from
It is deleted in isochronous queue 1.
If main business plate A is not received synchronizes successful message for what business board A1 was sent, main business plate A is to the link
List item is retransmitted, and is reached until receiving the number for synchronizing successful message or retransmitting that standby business board A1 is sent
When to threshold value, stop retransmitting.
If main business plate A receives the successful message that synchronizes that standby business board A1 sends, main business plate A is by the link table
Item is deleted from isochronous queue 1.If the number that main business plate A is retransmitted reaches threshold value, main business plate A is by the link table
Item is moved to explorer queue 1.
After the link list item is moved to explorer queue 1 by main business plate A, starts timing, determine that the link list item is detecting
In queue 1 there are durations.Monitoring this, there are durations whether to reach default detection duration, if reached, main business plate A is first to standby
Business board A1 sends probe messages, if main business plate A receives the detection response message that standby business board A1 is sent, main business
Plate A sends the link list item to standby business board A1 again.
If main business plate A does not receive standby business board A1 hairs in the second preset duration for sending the link list item again
That send synchronize successful message, then by the link list item in explorer queue 1 there are when length reset, and restart meter
When, determine the link list item in explorer queue 1 there are durations, and long the case where reaching default detection duration in the presence of this
Under, send probe messages to standby business board A1.Successfully disappear if main business plate A receives standby synchronizing for business board A1 transmissions
Breath, then main business plate A deletes the link list item from explorer queue 1.
Interactive process between main business plate A and standby business board A2 and the above process (main business plate A and standby business board A1 it
Between interactive process) it is similar, repeat no more.
Using embodiment illustrated in fig. 1 of the present invention, disappear in a first aspect, main business plate receives the notice that standby business board is sent
Breath indicates that main business plate can carry out data interaction with standby business board, and in this case, main business plate is sent to standby business board again
Link list item, the link list item that standby business board can send main business plate store, and therefore, this programme improves synchronous chain
The reliability of road list item.Second aspect, standby business board synchronize to the transmission of main business plate and successfully disappear after storing link list item
Breath can be again to standby business board transmission link list item, into one if main business plate, which does not receive this, synchronizes successful message
Step improves the reliability of synchronization link list item.The third aspect, main business plate is according to actual bandwidth service condition, to main business plate
The data volume that standby business board is sent in unit interval is adjusted, and scheme is flexible, more reasonable to the use of bandwidth.
Below with reference to Fig. 2 and Fig. 2 a, a kind of specific implementation mode is introduced, the network equipment includes a main business plate and two
A standby business board：Standby business board 1 and standby business board 2.Main business plate safeguards two isochronous queues：Isochronous queue 1 and isochronous queue
2, wherein isochronous queue 1 is the isochronous queue established for standby business board 1, and isochronous queue 2 is to be established for standby business board 2
Isochronous queue.Main business plate safeguards two explorer queues：Explorer queue 1 and explorer queue 2, wherein explorer queue 1 is for standby
The explorer queue that business board 1 is established, explorer queue 2 are the explorer queue established for standby business board 2.Main business plate is generating chain
After the list item of road, the link list item of generation is stored into each isochronous queue respectively.
Any standby interaction between business board and main business plate is similar, below in case being illustrated for business board 1.
S201：Standby business board 1 sends a notification message upon actuation or when in non-busy condition to main business plate.
S202：Main business plate after receiving the notification message, according between the standby business boards of main business plate and two can
With bandwidth, the data volume of the link list item sent is determined；Main business plate obtains link list item from isochronous queue 1, and according to institute
Determining amount of data, to 1 transmission link list item of standby business board.
Specifically, data volume can determine in the following manner.
Main business plate can obtain the total bandwidth between main business plate and standby business board, and determine main business plate and standby business
Bandwidth has been used between plate.
Main business plate is by the total bandwidth and the difference for having used bandwidth, as the available band between current business plate
It is wide.
Main business plate determines the byte value for any bar link list item that the link list item includes, and band can be used described in calculating
The wide quotient with the byte value determines the list item quantity sent in the unit interval according to the quotient.
Main business plate sends the quantity link list item according to determining list item quantity, to standby business board.
For example, usually, the total bandwidth between main business plate and standby business board is the hardware by the network equipment
It can determine, which may be considered a fixed value, can include the total bandwidth, main business in the product parameters of the network equipment
Business plate can obtain the total bandwidth by reading the product parameters.In addition, main business plate can according to main business plate with it is each standby
Interaction data amount between business board determines the bandwidth currently used up, that is, this has used bandwidth.Total bandwidth and bandwidth is used
Difference be available bandwidth between current business plate.
The usual difference of byte value of each of the links list item is little, it is believed that the byte value of wherein one link list item can be with
The byte value size of other link list items is represented, the quotient of " available bandwidth " and " byte value of any bar link list item " is calculated.One
It, can be using obtained quotient as the list item quantity sent in the unit interval in the case of kind；In another case, can will obtain
Quotient is multiplied with a threshold value, using obtained product as the list item quantity sent in the unit interval.The threshold value can be 0.6,0.7,
Or any value between 0.6-0.7, the concrete numerical value of the threshold value do not limit.
Main business plate can be according to the list item quantity being calculated, to 1 transmission link list item of standby business board；In other words,
When main business plate is to standby 1 transmission link list item of business board, the quantity link list item is sent in each unit interval.In this way, not
As for wasting bandwidth between extra plate, while the biography of business datum between other plates of bandwidth contributions between too many plate will not be occupied
It is defeated.
S203：Standby business board 1 stores the link list item received to this for business board 1, and is sent together to main business plate
Walk successful message.
S204：Main business plate deletes the link list item in isochronous queue 1 after receiving this and synchronizing successful message
It removes.
And if main business plate after sending the first preset duration of the link list item to standby business board 1, does not receive
This for business board 1 send synchronize successful message, then main business plate can each predetermined period, to the chain in isochronous queue 1
Road list item is once retransmitted, and successful message is synchronized for what business board 1 was sent until receiving.Later, main business plate
The link list item is deleted from isochronous queue 1, and stops the retransmission to the link list item.

Both there is newly-generated link list item in mode, in isochronous queue, there is also multiple send is not successfully transmitted yet to standby business board
Link list item；In the case of one kind, it can be marked to repeatedly sending the link list item not being successfully transmitted yet, main business plate is excellent
First send the link list item that there is label in isochronous queue.
Alternatively, in another case, main business plate can set the priority of all link list items in isochronous queue, it is newborn
The priority that repeatedly transmission is not successfully transmitted link list item yet can be less than at the priority of link list item, this is also rational.
If main business plate does not receive always synchronizes successful message for what business board 1 was sent, when main business plate is to this
After the number that link list item retransmits reaches predetermined threshold value, main business plate deletes the link list item from isochronous queue 1, and
The link list item is added in explorer queue 1.
After the link list item is added to explorer queue 1 by main business plate, starts timing, determine the link list item in detecting force
In row 1 there are durations.Monitoring this, there are durations whether to reach default detection duration, if reached, main business plate is first to standby industry
Business plate sends probe messages, if main business plate receives the detection response message that standby business board 1 is sent, main business plate is again
The link list item is sent to standby business board 1.
If main business plate after sending the link list item again, receives synchronizing successfully for the standby transmission of business board 1
Message, then main business plate is by the link table entry deletion in explorer queue 1.If main business plate is sending the link list item again
The second preset duration in do not receive that standby business board 1 sends synchronize successful message, then main business plate is by the link list item
There are when length reset, and restart timing, determine the link list item in explorer queue 1 there are durations, and deposit at this
