The embodiment of the present disclosure provides a kind of BFD conversation switching methods, can include：
When detecting that hardware conversation modes do not support BFD sessions, start the software sessions pattern for supporting BFD sessions；
Under the software sessions pattern, BFD messages are sent to opposite equip. corresponding to the BFD sessions, described in termination
The BFD sessions under hardware conversation modes；And when receiving the BFD messages that the opposite equip. is sent, described soft
The BFD sessions are maintained under part conversation modes.
Wherein, BFD sessions are maintained to refer to the SDK by software transfer BFD special chips under hardware conversation modes, and
The maintenance of BFD sessions is realized by BFD special chips.BFD sessions are maintained to refer to by software journey under software sessions pattern
Sequence realizes the maintenance of BFD sessions.
The embodiment of the present disclosure can realize that the configuration variation in BFD sessions causes hardware conversation modes not support BFD sessions
When, BFD sessions are smoothly switched to software sessions pattern by hardware conversation modes, avoid BFD sessions from shaking, so as to keep away
Exempt from customer service concussion.
In the disclosed embodiments, one group of BFD session is maintained to include two aspects：On the one hand it is that local device sends BFD
Message (optional, message can be sent in the first preset time period), on the other hand receive the BFD messages of opposite equip. transmission
(optional, message is received in the second preset time period).Either software sessions pattern or hardware conversation modes, when
Opposite equip. can receive BFD messages, BFD sessions not Down；When receiving BFD messages, the BFD sessions are maintained.In this public affairs
Open in embodiment, BFD session Down, refer to that BFD sessions are closed.
In certain embodiments, the BFD sessions of hardware conversation modes are smoothly switched under software sessions pattern and maintained,
Then show that current BFD sessions are unable to Down when conversation modes switch.Exemplary, can be complete within a BFD session cycle
Into the switching of conversation modes, now current BFD sessions not Down.Optionally, a BFD session cycle can include：Locally set
The standby BFD messages that opposite equip. transmission is received to opposite equip. transmission BFD messages and local device.
In certain embodiments, two timers can be set：First timer and second timer, wherein, the first timing
Device is set the first preset time period progress timing that BFD messages are sent to local device, when first timer time-out, this
Ground equipment sends BFD messages；Second timer, which is set, to be received the second preset time period of BFD messages to local device and enters
Row timing, when second timer time-out, show that local device does not receive BFD messages in the second preset time period.When
Local device starts timing to first timer during opposite equip. transmission BFD messages, and is received in the second preset time period
The BFD messages sent to opposite equip. start second timer timing.If local device does not connect in the second preset time period
Receive the BFD messages of opposite equip. transmission, then it represents that BFD session Down, now need to re-establish BFD sessions with opposite equip..
Stop after being sent due to BFD messages of the embodiment of the present disclosure under software sessions pattern under hardware conversation modes
BFD sessions, therefore the not Down of the BFD sessions under hardware conversation modes；Opposite equip. transmission is received under software sessions pattern
During BFD messages, the switching of conversation modes is completed within a BFD session cycle, BFD sessions are smoothly switched to software meeting
Maintained under words pattern.Optionally, under software sessions pattern, local device receives opposite end in the second preset time period and set
The BFD messages that preparation is sent.The embodiment of the present disclosure can realize that the configuration variation in BFD sessions causes hardware conversation modes not supported
During BFD sessions, BFD sessions are smoothly switched to software sessions pattern by hardware conversation modes, avoid BFD sessions from shaking
Swing, so as to avoid customer service from shaking.
Fig. 1 shows the flow chart of the BFD conversation switching methods according to the embodiment of the disclosure one.The executive agent of this method can
Think the equipment such as router, or the working plate in distributed communication equipment, the embodiment of the present disclosure are not restricted to this.Can
Choosing, the embodiment of the present disclosure is used to BFD sessions smoothly switching to the maintenance of software sessions pattern from hardware conversation modes.Such as figure
Shown in 1, in the method, local device maintains current BFD sessions under hardware conversation modes.
In step s 11, when detecting that hardware conversation modes do not support BFD sessions, the software for supporting BFD sessions is started
Conversation modes.
Wherein, BFD sessions are maintained to refer to the SDK by software transfer BFD special chips under hardware conversation modes, and
The maintenance of BFD sessions is realized by BFD special chips.BFD sessions are maintained to refer to by software journey under software sessions pattern
Sequence realizes the maintenance of BFD sessions.Generally, due to BFD special chips have preferable maintainability, in hardware conversation modes
In the case of being able to maintain that BFD sessions, then BFD sessions are maintained under hardware conversation modes as far as possible, to realize preferable maintainability
Energy.
In a kind of possible implementation, the hardware parameters of BFD sessions, time parameter, mode of operation, inspection are being detected
When the rule of the hardware chip of one or more and local device in survey pattern or operational mode mismatches, determination hardware session
Pattern does not support BFD sessions.
Wherein, the rule of hardware chip can refer to hardware chip in hardware parameter, time parameter, mode of operation, detection mould
Parameter area or condition and range that formula or operational mode etc. are pre-set etc..The mode of operation of BFD sessions can include control
Message mode processed or Echo message modes etc.；The detection pattern of BFD sessions can include single-hop detection, multi-hop detection or two-way inspection
Survey etc.；The operational mode of BFD sessions can be included in the aggressive mode before BFD session establishments or Passive Mode etc., and in BFD
Asynchronous mode or query pattern after session establishment etc..
As an example of the implementation, the parameter area that hardware chip is pre-set in terms of time parameter is T1
~T2.If local device detects that the time parameter of BFD sessions is T3, do not fall that (such as T3 is less than T1 or T3 in T1~T2 in T3
More than T2) in when, it is believed that the rule mismatch of the time parameters of BFD sessions and hardware chip, then local device judge hard
Part conversation modes do not support BFD sessions.
It should be noted that although with the hardware parameter of BFD sessions, time parameter, mode of operation, detection pattern or operation
Pattern describes the reason for causing hardware conversation modes not support BFD sessions as example as above, but those skilled in the art's energy
It is enough to understand, embodiment of the present disclosure not limited to this.Those skilled in the art can flexibly set according to practical application scene to cause firmly
Part conversation modes are supported and/or do not support the rule or parameter of BFD sessions.
In step s 12, under software sessions pattern, BFD messages is sent to opposite equip. corresponding to BFD sessions, are stopped
BFD sessions under hardware conversation modes；And when receiving the BFD messages of opposite equip. transmission, under software sessions pattern
Maintain BFD sessions.
In an optional embodiment, after BFD messages are sent to opposite equip., a control can be sent to local device and is referred to
Order, so that local device stops the BFD sessions under hardware conversation modes according to the control instruction.Optionally, to local hardware core
Piece sends a control instruction, so that hardware chip stops the BFD sessions under hardware conversation modes according to the control instruction.
In other optional embodiment, when step 11 starts hardware conversation modes, it becomes possible to perform in step S12
" sending BFD messages to opposite equip. corresponding to BFD sessions, stop the BFD sessions under hardware conversation modes ".
As an example of the present embodiment, BFD sessions 1 are established between device A and equipment B, for detection device A and
The failure in two-way converting path between equipment B.Wherein, for BFD sessions 1, device A is equipment B opposite equip., and equipment B is
The opposite equip. of device A.Established between device A and equipment B after BFD sessions 1, device A can be under hardware conversation modes
Maintain BFD sessions 1.If device A detects that hardware conversation modes do not support BFD sessions 1, start the software for supporting BFD sessions 1
Conversation modes.Device A sends BFD messages under software sessions pattern, to equipment B, stops the BFD sessions under hardware conversation modes
1, and when receiving the BFD messages of equipment B transmissions, BFD sessions 1 are maintained under software sessions pattern.
Which kind of it should be noted that it will be appreciated by those skilled in the art that safeguarded between device A and equipment B by mode
BFD sessions are without relevance and do not influence each other.For example, the situation of BFD sessions is maintained under hardware conversation modes in device A
Under, equipment B can maintain BFD sessions under hardware conversation modes, and BFD sessions can also be maintained under software sessions pattern.
In the case that device A maintains BFD sessions under software sessions pattern, equipment B can maintain BFD meetings under software sessions pattern
Words, can also maintain BFD sessions under hardware conversation modes.
It should be noted that it will be appreciated by those skilled in the art that in the case where device A has multiple BFD sessions, it is more
Individual BFD sessions without relevance and do not influence each other each other.For example, BFD sessions are established between device A and equipment B
1, BFD sessions 2 are established between device A and equipment C.If device A detects that hardware conversation modes do not support BFD sessions 2, open
The dynamic software sessions pattern for supporting BFD sessions 2.Device A sends BFD messages under software sessions pattern, to equipment C, stops hard
BFD sessions 2 under part conversation modes, and when receiving the BFD messages of equipment C transmissions, maintained under software sessions pattern
BFD sessions 2.Thus, device A maintains BFD sessions 1 under hardware conversation modes, and BFD sessions 2 are maintained under software sessions pattern.
In correlation technique, after the BFD sessions safeguarded under establishing hardware conversation modes, if detecting matching somebody with somebody for BFD sessions
When putting change causes the hardware conversation modes not support BFD sessions, then need that BFD sessions first are arranged into Admin Down states,
Then the BFD sessions that session negotiation is safeguarded to establish under software sessions pattern are re-started again.The BFD sessions of the embodiment of the present disclosure
Switching method, if detect the configuration variation of BFD sessions and cause the hardware conversation modes not support BFD sessions, start and support BFD
The software sessions pattern of session, under software sessions pattern, BFD messages are sent to opposite equip. corresponding to BFD sessions, are stopped hard
BFD sessions under part conversation modes, and when receiving the BFD messages of opposite equip. transmission, tieed up under software sessions pattern
Hold BFD sessions.During thus, it is possible to realize that the configuration variation in BFD sessions causes the hardware conversation modes not support BFD sessions, smoothly
BFD sessions are switched to software sessions pattern by ground by hardware conversation modes, avoid BFD sessions from shaking, so as to avoid user
Business is shaken.
In a kind of possible implementation, BFD sessions are maintained under software sessions pattern, including：Periodically to right
End equipment sends BFD messages；Periodically detect the BFD messages that opposite equip. is sent.
Wherein, BFD sessions are maintained under software sessions pattern, periodically send BFD messages to opposite equip., including：
BFD messages are sent to opposite equip. by software program at interval of the first preset time period.Maintained under software sessions pattern
BFD sessions, the BFD messages that opposite equip. is sent periodically are detected, including：Pass through software at interval of the second preset time period
The BFD messages that Programmable detection opposite equip. is sent.First preset time period and preset time period can be advance when second
The time span of setting, the embodiment of the present disclosure are without limitation.First preset time period can be between 10 milliseconds to 1 second
Numerical value.Second preset time period can be 3 to 5 times of the first preset time period.For example, the first preset time period can
Think 30 milliseconds, the second preset time period can be 90 milliseconds.
It is understood that the preset time period of ratio first that the second preset time period is set is long, this can be caused
Ground equipment may have sent more than one BFD messages in second preset time period and (such as have sent three BFD report
Text), as long as and opposite equip. receives one of BFD messages and can cause BFD sessions not Down, add BFD meetings
The serious forgiveness of words, the success rate that BFD sessions are smoothed switching is improved, reduce BFD sessions and customer service shakes
Possibility.
As an example of the implementation, BFD sessions 1 are established between device A and equipment B.In software sessions mould
BFD sessions 1 are maintained under formula, then two timers, transmission timer and detection timer are set in the software program of device A.
Transmission timer is arranged to overtime when more than the first preset time period.In the case of transmission timer time-out, device A can
To send BFD messages to equipment B by software program, to ensure that equipment B can receive periodic BFD messages, equipment B will not
BFD sessions 1 are closed.Detection timer is arranged to overtime when more than the second preset time period.In detection timer expiry
In the case of, if device A receives the BFD messages sent to equipment B not over software program, then it represents that device A is pre- second
If receiving the BFD messages of equipment B transmissions in the time cycle not over software program, device A closes BFD sessions 1.
In a kind of possible implementation, BFD messages include being used for the status information for representing BFD session status, then exist
BFD sessions are maintained under software sessions pattern, including：When being determined to establish state Up BFD sessions according to status information,
BFD sessions are maintained under software sessions pattern.When to determine current BFD sessions be Up according to state, represent that BFD sessions are put down
It is switched under software sessions pattern and maintains slidingly.
It is understood that the current shape of BFD sessions can be noticed between equipment by the state field in BFD messages
State.Wherein, BFD sessions may have four kinds of states：State Admin Down (state field 0), state Down (State words
Section for 1), state I nit (state field 2) and state Up (state field 3).State Admin Down show BFD sessions
The person of being managed forces Down, and this will enter opposite equip. and be maintained at state Down.State Down represents that BFD sessions are closed
Close, thus the link or network failure between equipment corresponding to BFD sessions.State I nit represent local device with it is right
In end equipment communication, local device wishes to make BFD session establishments, but opposite equip. does not recognize this change also.Shape
State Up represents the success of BFD session establishments and normal work, is thus connected between equipment corresponding to BFD sessions normal.
In correlation technique, the process that BFD sessions are established between device A and equipment B is as follows：Device A and equipment B start BFD,
It is each initially state Down.Device A sends carrier state Down BFD messages to equipment B.Equipment B receives carrying shape
State Down BFD messages, then state I nit is switched to, and carrier state Init BFD messages are sent to device A.Equipment B is being cut
The BFD messages changed to state I nit and then receive carrier state Down do not process then.The BFD state change mistakes of device A
Journey is same as above.Equipment B receives carrier state Init BFD messages, then is switched to state Up.The BFD state change processes of device A
Ibid.The BFD states of local device are that state UP indicates the success of BFD session establishments.In device A and equipment B generating states Down
To after state I nit change, then detection timer is respectively started, the effect for detecting timer is to prevent the BFD of local device
State block is in state I nit.It is local if not receiving state I nit or state Up BFD messages yet within the defined time
The BFD state auto-switchings of equipment return state Down.
As an example of the implementation, BFD sessions 1 are established between device A and equipment B.In device A and equipment
Established between B after BFD sessions 1, device A can maintain BFD sessions 1 under hardware conversation modes.If device A detects hardware
Conversation modes do not support BFD sessions 1, then start the software sessions pattern for supporting BFD sessions 1.Device A is in software sessions pattern
Under, the BFD messages for including state Up are sent to equipment B, stop the BFD sessions 1 under hardware conversation modes, and set receiving
During the BFD messages including state Up that standby B is sent, BFD sessions 1 are maintained under software sessions pattern.
In a kind of possible implementation, stop the BFD sessions under hardware conversation modes, including：Delete hardware chip
In BFD sessions information；Or stop the BFD messages that hardware chip periodically detects opposite equip. transmission.
It should be noted that it will be appreciated by those skilled in the art that multiple BFD meetings are there may be under hardware conversation modes
Words.For example, establishing BFD sessions 1 between device A and equipment B, BFD sessions 2 are established between device A and equipment C, in device A
BFD sessions 3 are established between equipment D, then can include BFD sessions 1, BFD sessions 2 and BFD under the hardware conversation modes of device A
Session 3.Wherein, BFD sessions 1, BFD sessions 2 and BFD sessions 3 can be recorded by modes such as lists.
As an example of the implementation, BFD sessions 1 are switched to software sessions pattern by hardware conversation modes.If
Standby A can stop the BFD sessions 1 under hardware conversation modes by deleting the information of the BFD sessions 1 in hardware chip.Work as equipment
A receive opposite equip. transmission BFD messages when, due in hardware chip without the information of BFD sessions, therefore will not again from
BFD messages are matched in hardware chip, but the BFD messages are sent to software sessions pattern and matched, so as to stop hardware
BFD sessions 1 under conversation modes.For example, the processor of device A can be sent for deleting in hardware chip to hardware chip
The instruction of the information of BFD sessions 1, to delete the information of the BFD sessions 1 in hardware chip, when device A receives opposite equip. hair
During the BFD messages sent, BFD messages will not be matched from hardware chip again, but the BFD messages are sent to software sessions pattern
Matched, so as to stop the BFD sessions 1 under hardware conversation modes.
As another example of the implementation, BFD sessions 1 are switched to software sessions pattern by hardware conversation modes.
Device A can be stopped under hardware conversation modes by stopping the hardware chip BFD messages that periodically detection device B is sent
BFD sessions 1.For example, the processor of device A can be sent to hardware chip for stopping hardware chip periodically detection device
The instruction for the BFD messages that B is sent, it is hard so as to stop to stop the hardware chip BFD messages that periodically detection device B is sent
BFD sessions 1 under part conversation modes.
Distributed communication equipment can be an equipment being made up of multiple working plates, externally show as an entirety, and
Each share some business in inside.Wherein, working plate can include master control borad and business board.For BFD sessions, overall control can
To be realized on master control borad, and specifically safeguard and can be realized on enclosure board, i.e., the transmission of BFD messages is responsible for by enclosure board and connect
