Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is a part of embodiment of the present invention, and not
It is whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making wound
The every other embodiment obtained on the premise of working by the property made, should all belong to the scope of protection of the invention.
Fig. 1 is a kind of indicative flowchart of the method for process message of the embodiment of the present invention, the method
Executive agent can be first network equipment, as shown in figure 1, the method 100 includes：
110, first network equipment receives the first message that second network equipment sends, and the first message is carried
The status information of the first link, the life span that the first message is carried have reached maximum aging time.
120, if second network equipment is in abnormality, first network equipment is receiving the first message
Initial time starts first timer, and the timing length of first timer is the first duration, in the first timing
After device time-out, first message participates in router-level topology.
Specifically, by taking OSPF systems as an example, in OSPF systems, the LSA that the network equipment is generated
Message (belonging to a LSA of second network equipment) can carry opening up for the network equipment respective link
Relation information or routing iinformation are flutterred, that is, carries the state letter of one or more link that the network equipment is generated
Breath, an age field is carried in the LSA to be used to represent the life span of the LSA, during the existence
Between can also referred to as generate the time, when age fields life span reach maximum lifetime MaxAge
When (being 3600s in OSPF systems), it will delete in local data base.Similarly, exist
In IS-IS systems, the LSP that the network equipment is generated also carries the life span of the age field identifications LSP,
In LSP, the maximum lifetime of the acquiescence of age fields is 1200s, when the life of age fields in LSP
When depositing time arrival MaxAge, also can delete in local data base.Therefore, when certain network sets
It is standby receive a MaxAge LSA or LSP when, it will delete LSA in local data base or
LSP。
In step 110, first network equipment and second network equipment are that the different network of any two sets
Standby, the status information of first link is generated by second network equipment, the state letter of first link
The content of breath is the link topology relation information or routing iinformation of second network equipment, and the first message is carried
The status information for having reached the first link of maximum aging time refers to the age fields institute in first message
The life span of instruction has been maxed out ageing time, such as the age fields in LSA have reached
Age fields in 3600s or LSP have reached 1200s.
Specifically, in the step 120, if second network equipment for generating the first message is in abnormality,
First network determines that the first Link State for having maximum aging time in the first duration is not immediately engaged in
Router-level topology, that is to say, that a period of time will be maintained not delete first Link State, specifically：First
There is first timer on the network equipment, the timing length of the first timer is the first duration, first
In duration, first message is not involved in router-level topology, and after first timer time-out, the first message will
Participate in router-level topology.
For example, the age fields of LSA that first network equipment receives the generation of second network equipment are
MaxAge, then first network equipment will maintain the first duration in do not delete the LSA, this first when
Router-level topology is not carried out to the LSA with MaxAge in long, after first timer time-out, the tool
The LSA for having MaxAge will participate in router-level topology.
Specifically, the first duration of first timer setting needs to be connect by the message between each network equipment
Determine between the time receiving, for example, the first duration could be arranged to 1s, 5s, 10s, and above-mentioned numerical value is only to show
Example property, the invention is not restricted to this.
Method provided in an embodiment of the present invention and its network equipment, can be by judging to take in the message for receiving
Whether the life span of band reaches maximum aging time, it is determined whether carry out route meter using the message immediately
Calculate, when the life span that the network equipment for sending the message is carried in abnormality, and the message reaches
During to maximum aging time, postpone deleting the status information of the link, determine that the message is not wrong deletion
When, then the message is deleted, otherwise, and walking along the street is entered according to the status information of the local link that there is currently
By calculating.Therefore, it can reduce, due to route oscillation caused by mistake deletion message, causing so as to reduce
The probability that service traffics are lost.
Alternatively, as one embodiment of the invention, first report is received in the first network equipment
Before text, methods described also includes：The first network equipment receives what second network equipment sent
Second message, second message carry the topology status information of the second link, and second message is carried
Life span reached maximum aging time；According to second message, determine that second network sets
It is standby to be in abnormality.
Specifically, the topology status information of the second link is referred to for describing the link shape of topological relation information
State, for example, can be the Router LSA of the LSP or OSPF of ISIS zero pieces, and the second message is taken
The life span of band has reached maximum aging time and has referred to that second message will be deleted in participation router-level topology
Remove, the message for carrying the second Link State can refer to the ISIS zeros piece LSP messages or OSPF of MaxAge
Router LSA messages.
After first network equipment receives the second message of second network equipment transmission, second net will be determined
Network equipment is in abnormality, in other words, will generate the second network equipment labelling of second Link State
The Link State of second network equipment is entered and is suppressed for abnormality, that is, triggering first network equipment
The special state of router-level topology.It should be understood that the first message and the second message can be same message, i.e.,
The topology status information of the second link that first message is carried can be with the first of second message carrying
The status information of link is identical, and the life span that the first message and the second message are carried all reaches maximum aging
Time, that is to say, that the trigger condition for second network equipment to be labeled as abnormality is first network
Equipment receives the second message carrying life span of second network equipment transmission and has reached maximum aging time
And the second message carries the topology status information of Link State.
Alternatively, as one embodiment of the invention, the second message is intermediate system to intermediate syst
Zero piece Link State Packet (English：ISIS zero pieces) or OSPF route chain
Line state issues (English：OSPF Router LSA).
It should be understood that for OSPF, as long as there is active region, Router LSA will be deposited always
, will not the person of being generated delete.The zero piece of the LSP of ISIS, enters simply by the presence of active ISIS in the same manner
Journey, will be present always, for other bursts of other kinds of LSA or LSP, be possible to deposit
, it is also possible to it is non-existent.When the reason for OSPF Router LSA/ISIS zero piece the whole networks are deleted,
Can only be equipment trustship, or caused by various software bug or intervalometer are forbidden.
Alternatively, as one embodiment of the invention, according to the second message, determine at second network equipment
In abnormality, including：First network equipment determines that second network equipment is in the second duration
Abnormality, wherein, the second duration receives moment of the second message to rise with the first network equipment
Begin the moment, when second, a length of second network equipment generates the time interval of link-state information.
Specifically, first network equipment was opened from the moment of the second Link State for receiving second network equipment
In the second duration after beginning, second network equipment belonging to the second Link State is labeled as into abnormality.
That is, setting when first network equipment receives any one in the second duration and belongs to second network
During the standby Link State with maximum aging time, being required for determining in the first duration should be with maximum
The Link State of ageing time does not immediately engage in router-level topology, but starts first timer, fixed first
When device time-out reach the first duration after, should with maximum aging time Link State just participates in route count
Calculate.
Specifically, second when a length of second network equipment generate the time interval of link-state information,
That is, a length of second network equipment generates the cycle of link-state information when second.That is,
In OSPF, the second duration can be the refresh cycle of LSA, such as 1800s etc., in ISIS feelings
Under condition, it is also possible to be set to 900s, the invention is not restricted to this.
Specifically, the reason for being set to the second duration is as follows：1. delete network if there is faulty equipment to set
All Link States of standby A, the deletion process is to delete one by one, accordingly, it would be desirable in the second duration,
Suppression is entered all it is determined that receiving and belonging to all LSP with maximum aging time or LSA of network equipment A
Router-level topology process processed, i.e., be not involved in router-level topology in the first duration；2. event is judged in the second duration
Whether equipment can also delete the Link State of the miscellaneous equipment in addition to network equipment A.Therefore, as long as
Ensure that the duration of above-mentioned 1,2 conditions can be set to the second duration, for example, the second duration can
To be set to 2000s, 1000s etc., the invention is not restricted to this.
Alternatively, as one embodiment of the invention, said method also includes：When first network equipment exists
The 3rd message is received when first timer has not timed out, is cancelled first timer, and is carried out using the 3rd message
Router-level topology, wherein, the 3rd message carries the status information of the first link, the existence that the 3rd message is carried
Have not timed out up to maximum aging time.
Specifically, when first network equipment receives the status information for carrying the first link in the first duration
3rd message, and the 3rd message carry the generation time also be not up to maximum aging time, immediately using should
3rd message carries out router-level topology, does not adopt the generation time to have been maxed out the first link of ageing time
Status information carry out router-level topology；When first network equipment does not receive above-mentioned 3rd report in the first duration
The first message that the carrying generation time has reached maximum aging time is carried out router-level topology, also by Wen Shi
It is to say.
It may also be said that in the first duration from first network equipment received for the first message moment, if received
To the 3rd message, just may determine that the first message for receiving before is sent by network equipment mistake immediately
, therefore the first message would not allow for participation router-level topology, but the message for receiving is carried out into route meter
Calculate, to realize routing update.
Method provided in an embodiment of the present invention and its network equipment, can be by judging to take in the message for receiving
Whether the life span of band reaches maximum aging time, it is determined whether carry out route meter using the message immediately
Calculate, when the life span that the network equipment for sending the message is carried in abnormality, and the message reaches
During to maximum aging time, postpone deleting the status information of the link, determine that the message is not wrong deletion
When, then the message is deleted, otherwise, and walking along the street is entered according to the status information of the local link that there is currently
By calculating.Therefore, it can reduce, due to route oscillation caused by mistake deletion message, causing so as to reduce
The probability that service traffics are lost.
Fig. 2 is a kind of indicative flowchart of the method for process message of the embodiment of the present invention.Such as Fig. 2 institutes
Show, the method 200 includes：
201, determine that network equipment A is labeled as abnormality by local network device.That is at this
Under abnormality, all Link States with maximum aging time of network equipment A all enter into suppression
In the special state of router-level topology.
202, local network device is received when belonging to the life span of network equipment A and having reached maximum aging
Between Link State.Specifically, for example, local network device receives the MaxAge of network equipment A transmissions
LSP, then local device will quickly flood Link State LSP, quickly to trigger the generation of the LSP
Network equipment A refreshes again, when the LSP of network equipment A is deleted by mistake, network equipment A
New LSP can be produced, and the LSP after the renewal is sent to local network device, in order to local network
Equipment carries out router-level topology according to the LSP after the renewal.
203, the above-mentioned Link State with maximum aging time enters the slow calculating state of route, that is,
Say that there is the Link State of maximum aging time in T1 durations not carry out router-level topology for this, receive this
Start T1 intervalometers during Link State.
204, when in T1 durations, receive the network equipment A renewal Link State the generation time not
When reaching maximum aging time, immediately the Link State that the life span is not up to maximum aging time is replaced
The Link State with maximum aging time for alternatively before receiving, and router-level topology is immediately engaged in, cancel
T1 intervalometers.For example, in T1 durations, when local network device receives the life of network equipment A renewals
When the LSP/LSA of maximum aging time is not reaching to into the time, the LSP/LSA after renewal is replaced it
Before the LSP or LSA that reach maximum aging time that receive, exist side by side, LSP that will be after the renewal
Or LSA carries out router-level topology.
205, local network device does not receive the life span of network equipment A renewals in T1 durations
Not up to the Link State of maximum aging time when, by the life for receiving in step 202. after T1 durations
The Link State that ageing time is had been maxed out into the time participates in router-level topology, that is, deleting should be with maximum
The Link State of ageing time.
For example, in step 204 and 205, local network device postpones T1 durations and will generate the time
Jing reaches the Link State of maximum aging time carries out router-level topology, and waits the generator of the Link State
Equipment refreshes the Link State.If in T1 durations, local network device receives network equipment A refreshings
Generate the time be not up to maximum aging time Link State, then by the newest generation time for receiving not
Reach maximum aging time Link State replace before when receiving the generation time and having reached maximum aging
Between Link State；If in T1 durations, not receiving the not Link State with maximum aging time,
So after the T1 times, the Link State will be deleted, by the Link State with maximum aging time
Carry out router-level topology.That is, local device is during the delay router-level topology of T2 times, wait
The original device of purge messages/flush messages refreshes the message to correct.If receiving before timer expiry
Refresh LSP/LSA, then carry out LSP/LSA merging treatments, it is to avoid delete route；If not receiving brush
New LSP/LSA, then after timer expiry reinform routing calculation module, do route delete processing.
Method provided in an embodiment of the present invention and its network equipment, can be by judging to take in the message for receiving
Whether the life span of band reaches maximum aging time, it is determined whether carry out route meter using the message immediately
Calculate, when the life span that the network equipment for sending the message is carried in abnormality, and the message reaches
During to maximum aging time, postpone deleting the status information of the link, determine that the message is not wrong deletion
When, then the message is deleted, otherwise, and walking along the street is entered according to the status information of the local link that there is currently
By calculating.Therefore, it can reduce, due to route oscillation caused by mistake deletion message, causing so as to reduce
The probability that service traffics are lost.
Fig. 3 is the indicative flowchart of the method for the process message of another embodiment of this law, and the method is used for
Local network device determines that belonging to a certain network equipment is locally being marked as abnormality.As shown in figure 3,
The method includes：
301, local network device receives the Link State for belonging to network equipment A, for example, receive LSA
Or LSP.
302, local network device judges whether the Link State for receiving is had timed out for survival up to maximum
Ageing time and carry network equipment A topological relation Link State, for example determine whether equipment
The MaxAge ISIS zero piece LSP or MaxAge OSPF Router LSA that A sends.
303, judge whether network equipment A is locally labeled as abnormality, namely whether be marked as
Suppress the special state of router-level topology.
304, if identified network equipment A is abnormality to local device, then need in the case where connecing
It is abnormality that the T2 durations for coming continue to network equipment A, and specific implementation can be by refreshing
The mode of T2 intervalometers is realizing.
305, if it is abnormality that local device is token network device A, then need following
T2 duration internal labeling network equipments A be abnormality, and start T2 intervalometers.
306, after T2 timer expiries, i.e., the network equipment does not receive the life in T2 durations again
Maximum aging time has been reached into the time and carried the Link State of the topological relation of network equipment A, then
The link shape that network equipment A leaves abnormality, i.e. network equipment A is identified on local network device
State need not be entered and suppress router-level topology state.
It should be understood that the main purpose of setting T2 durations has following two：1. delete if there is faulty equipment
Except all Link States of network equipment A, the deletion process is to delete one by one, accordingly, it would be desirable to first
In the section time, it is determined that receiving all LSP with maximum aging time or LSA for belonging to network equipment A
Suppression router-level topology process is all entered, i.e., router-level topology is not involved in T1 durations；2. failure judgement sets
The standby Link State that whether can also delete the miscellaneous equipment in addition to network equipment A.
If it should also be understood that before T2 is overtime, have received the router LSA/ISIS of MaxAge again
LSP zero pieces, need refresh timer.Before T2 timer expiries, receive non-MaxAge's
When router LSA/IsIs zero pieces, T2 intervalometers are not stopped.T1 intervalometers and T2 intervalometers are not
Together, when the router LSA/IsIs LSP zero pieces of non-MaxAge are received, directly stop T1
Intervalometer, participates in router-level topology.
Method provided in an embodiment of the present invention and its network equipment, can be by judging to take in the message for receiving
Whether the life span of band reaches maximum aging time, it is determined whether carry out route meter using the message immediately
Calculate, when the life span that the network equipment for sending the message is carried in abnormality, and the message reaches
During to maximum aging time, postpone deleting the status information of the link, determine that the message is not wrong deletion
When, then the message is deleted, otherwise, and walking along the street is entered according to the status information of the local link that there is currently
By calculating.Therefore, it can reduce, due to route oscillation caused by mistake deletion message, causing so as to reduce
The probability that service traffics are lost.
Fig. 4 is the indicative flowchart of the method for the process message of another embodiment of the present invention.
As shown in figure 4, OSPF/ISIS neighbours are set up between equipment, import from tester and route, route
Path be tester->PE1->PE2->P2->P1->P4->PE3->PE4->, there is node event in tester
Barrier source.
In the prior art, source of trouble intervalometer failure cause it is too fast aging, such as, when intervalometer fast 100
Times when, time of the LSA of other equipment just arrives 36S (less than refresh time), faulty equipment other
The LSA of equipment has arrived at 3600S, he will the whole network notify delete it is all of from PE1, PE2,
The LSA of P1, P2, P3, P4, PE3, PE4.(LSA of faulty equipment oneself will not be deleted, because
It is, to 18S, will to refresh and notify other equipment), so, when P4 receives the MaxAge of oneself generation
During LSA, can regenerate one time, but receive the MaxAge LSA of other equipment, will be immediately
Calculate route, will route delete, also can the whole network notify delete these MaxAge LSA, other equipment class
Seemingly.So, route can be deleted.When only all devices are all subject to the MaxAge LSA of respective maximum,
Regenerate these LSA the whole networks to flood.Route can just be recovered.
The source of trouble is periodically by PE1, PE2, P1, P2, P3, P4, PE3, the LSA on PE4
Delete, it is assumed that the network equipment A for being deleted route is PE1, and failed network device B is P4.Failure
The all of LSA of network equipment A is deleted periodically in source.
As the embodiment of the present invention, for failed network device B, the cycle that source of trouble timing is deleted
Less than the duration T2 times that the network equipment is labeled as special state, (T2 that OSPF chooses is exactly OSPF
Refresh time, ISIS choose be default refresh time), the LSA in the source of trouble is not also reached
3600S, will receive the refreshing LSA of other equipment, and the time starts from scratch calculating.Would not occur complete
The thing that net is deleted.
As the embodiment of the present invention, for network equipment A, the cycle that the source of trouble is deleted is less than T1
