Description
Technical field
The present invention relates to network communication technology field, in particular in a kind of LISP mapping server restart restoration methods and
Device.
Background technique
Position and identity separated protocol (LISP, Locator/Identity Separation Protocol) are a kind of positions
The networking thought of separation is set and identified, two independent address spaces: endpoint identifier (EID, Endpoint are formed
Identifier) address space and route location identifier (RLOC, Routing Locator) address space.EID is communication ends
The host address of point, identical as existing realization, the effect in LISP is similar to domain name system (DNS), possesses independent space.
In LISP network, EID can be migrated independently of RLOC, and RLOC is the address of LISP router, can be in existing internet
Middle routing forwarding global can route, and be polymerize according to network topology situation.The message communicated between EID is encapsulated in RLOC
Between tunnel in be forwarded.
LISP passes through entrance tunnels router (ITR, Ingress Tunnel Router) and exit tunnel router
(ETR, Egress Tunnel Router) realizes the separation of core network and edge network, it is used by a mapped system
To realize the Mapping Resolution from EID to RLOC.LISP is realized by the encapsulation and decapsulation mechanism of IP-in-IP in core net
In routing and forwarding.
Wherein, mapped system includes mapping server (MS, Map-Server), and MS plays important work in LISP network
With.The communication process of LISP is as follows:
1) (Map-Register) message is registered in the mapping that ETR is periodically sent to MS, notifies the EID-RLOC of itself
Mapping relations.MS receives logon message, saves LISP mapping table.
2) when the connected LISP host of ITR will a LISP main-machine communication connected to ETR when, data message reach
After ITR, ITR sends mapping request (Map-Request) message to MS, and the EID-RLOC being stored in LISP mapping table is requested to reflect
Penetrate information.
3) MS responds mapping response (Map-Reply) message to ITR, reports to EID-RLOC mapping relations.
4) ITR gets the corresponding address RLOC opposite end EID from EID-RLOC mapping relations.
5) ITR carries out LISP encapsulation to the data message, and using the RLOC of oneself as source address, the RLOC with opposite end ETR is
Destination address is sent to ETR by the tunnel LISP.
6) ETR receives LISP encapsulated message, removes LISP encapsulation, initial data message is transmitted to destination host.
It should be noted that all LISP mapping relations will lose, during this period by nothing when MS equipment fault is restarted
Method responds Map-Request request, will lead to LISP service disconnection.
In the prior art, can also be backed up by configuring more MS servers, on ITR can according to routing, to
Reachable MS is routed to make requests.When so wherein one failure, if routing reachable MS server there are also other
If, still it can work normally.
But if this server restarted after rebooting, needs to receive Map-Register registration again
Message, since the mapping database of this when is not complete, and MS server can not judge oneself mapping database whether
It is that completely, if still receive Map-Request message at this time, corresponding mapping is not safeguarded also, MS meeting at this time
The response of Negative type is responded, the response that such ITR receives this Negative will abandon data message, not turn
Hair, leads to service disconnection.
Summary of the invention
The purpose of the present invention is to provide mapping servers in a kind of LISP to restart restoration methods and device, can send out in MS
When raw failure is restarted, it is ensured that LISP business is not interrupted.
For achieving the above object, the present invention provides mapping servers in a kind of LISP to restart restoration methods, application
The i.e. main MS of MS that Yu Yizhu mapping server MS identity is restarted, this method comprises: being received when in the main MS for restarting recovery state
To tunnel router TR send mapping request Map-Request message when, according to itself preconfigured other backups MS's
The mapping request message is transmitted to backup MS by address, so that backup MS is by mapping response message to the mapping request of the TR
Message is replied.
For achieving the above object, the present invention also provides mapping servers in a kind of LISP to restart recovery device, should
Device is applied to the i.e. main MS of MS restarted with main mapping server MS identity, which includes: reception retransmission unit, for when place
When the main MS for restarting recovery state receives the mapping request Map-Request message of tunnel router TR transmission, according to certainly
The mapping request message is transmitted to backup MS by the address of preconfigured other backups MS of body, so that backup MS is rung by mapping
Message is answered to reply the mapping request message of the TR.
In conclusion being mutually backups between MS of the embodiment of the present invention, and on every MS, configure the ground of other backups MS
Location.When one of MS is restarted, recovery state is restarted in maintenance, receives tunnel router when being in the MS for restarting recovery state
When mapping request (Map-Request) message that TR is sent, which is carried out to the encapsulation of LISP protocol message, is turned
Other backups MS is issued to be handled.In this way, would not be as the prior art, MS in the reboot process, or is restarting it
Afterwards, to before receiving all Map-Register messages, if the MS still receives Map-Request message, MS
The response of Negative type can be responded, the response that such TR receives this Negative will abandon data message, not turn
Hair, leads to service disconnection.The present invention so as to solving MS in the reboot process, or after restarting but LISP mapping data

Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, right hereinafter, referring to the drawings and the embodiments,
Scheme of the present invention is described in further detail.
Core of the invention thought is, is mutually backups between MS, and on every MS, configures the ground of other backups MS
Location.When one of MS is restarted, recovery state is restarted in maintenance, receives tunnel router when being in the MS for restarting recovery state
When mapping request (Map-Request) message that TR is sent, which is carried out to the encapsulation of LISP protocol message, is turned
Other backups MS is issued to be handled.In this way, would not be as the prior art, MS in the reboot process, or is restarting it
Afterwards, to before receiving all Map-Register messages, if the MS still receives Map-Request message, MS
The response of Negative type can be responded, the response that such TR receives this Negative will abandon data message, not turn
Hair, leads to service disconnection.The present invention so as to solving MS in the reboot process, or after restarting but LISP mapping data
In the also unrecovered situation in library, the problem of cannot respond to Map-Request message, lead to LISP service disconnection.
Mapping server is restarted restoration methods and is included the following steps in LISP of the embodiment of the present invention, and flow diagram is as schemed
Shown in 1.
Step 11, as the mapping request Map- for receiving tunnel router TR transmission in the main MS for restarting recovery state
When Request message, which is transmitted to by backup MS according to the address of itself preconfigured other backups MS；
Step 12, backup MS reply the mapping request message of the ITR by mapping response message.
The main MS receive tunnel router TR transmission mapping request Map-Request message before, this method into
One step comprises determining that whether itself is provided with the address of other backups MS in advance, if it is, itself is arranged to restart recovery shape
State；If it is not, then itself is arranged to restore completion status.
Wherein, backup MS is transmitted to after which to be carried out to the encapsulation of LISP protocol message in step 11.It will
The mapping request message carries out the encapsulation of LISP protocol message, is usually packaged control information to mapping request message
(ECM, Encapsulated Control Message) encapsulation, the source IP of ECM encapsulation are the server address as main MS, mesh
IP be server address as backup MS.Server as main MS can be sent to each backup MS to be encapsulated by ECM
Mapping request message, ITR only handle the mapping response message that the First backup MS received is sent.
Further, main MS is by interacting recovery request message with backup MS and restoring response message, fast quick-recovery itself
LISP mapping database after to be restarted as the prior art etc., then receives mapping logon message again.Cause
This, the method for the present invention further comprises:
The main MS sends recovery request message to each backup MS according to the address of other backups MS configured, with
The LISP mapping database content for saving backup MS will locally responds to main MS by restoring response message；The LISP reflects
Penetrate the mapping relations that database includes multiple EID and RLOC.
After backup MS receives recovery request message, recovery state is restarted if be also in itself, recovery is not handled and asks
Seek message.So if the main MS is not received by the recovery response message of any backup MS response in the given time,
Illustrate that all backup MS further comprise all in recovery state, this method is restarted: the main MS, which is determined, restarts recovery time-out, will
It itself is set as restoring completion status.
When the main MS, which is received, carries the recovery response message for completing marker bit, the LISP mapping number of itself is determined
Restore to complete according to library, then itself will be set as restoring completion status.
When the main MS, which is received, does not carry the recovery response message for completing marker bit, sent again to backup MS extensive
Multiple request message, the remainder for the LISP mapping database that request backup MS is saved carry completion mark until receiving
Remember the recovery response message of position；
Wherein, it carries in the size order row for restoring the LISP mapping database in response message according to the mapping address EID
Column；
Described is again to receive last time to restore in response message to the initial address that backup MS sends recovery request message
The last one mapping the address EID；It is for the first time 0.0.0.0/0 to the initial address that backup MS sends recovery request message.
For security consideration, this method further comprises: when receiving the recovery response message of backup MS, the master
MS is decrypted in the encrypted message restored in response message to carrying, determines standby according to the safety verification password itself configured
When the safety verification password that the side part MS is configured is consistent with the safety verification password that main MS is configured, it will restore in response message
LISP mapping database is saved；Otherwise, the recovery response message is abandoned.
In this way, server as main MS in the reboot process can fast quick-recovery LISP mapping database, further
Ensure that LISP business is not interrupted.
It is of the invention to clearly illustrate, concrete scene is set forth below and is described in detail.
1) firstly, in LISP network, more MS of arrangement are mutually backups.Assume there are 3 MS difference in the embodiment of the present invention
For MS1, MS2 and MS3, it is mutually backups.
Specific implementation can be, the IP address of this 3 MS is configured on ITR.Meanwhile ETR sends Map- to every MS
Register message saves the EID-RLOC mapping relations of ETR on every MS.
2) on every MS, by configuration order lisp ms-peer x.x.x.x, the IP of all other backup MS in configuration
Address.If there is more backup MS, then a plurality of configuration order is configured.
2 configuration orders are configured on MS1, are lisp ms-peer 2.2.2.2 and lisp ms- respectively
peer3.3.3.3.It 2.2.2.2 is the IP address of MS2,3.3.3.3 is the IP address of MS3.
Similarly, 2 configuration orders are configured on MS2, are lisp ms-peer 1.1.1.1 and lisp ms- respectively
peer3.3.3.3.It 1.1.1.1 is the IP address of MS1,3.3.3.3 is the IP address of MS3.
Similarly, 2 configuration orders are configured on MS3, are lisp ms-peer 1.1.1.1 and lisp ms- respectively
peer2.2.2.2.It 1.1.1.1 is the IP address of MS1,2.2.2.2 is the IP address of MS2.
3) when MS is restarted, recovery state is restarted in maintenance one, if restarted, determines that itself has lispms-peer to match
It sets, illustrates the MS for having backup, itself is set at this time to restart recovery state；If configured without lisp ms-peer, explanation does not have
With the presence of MS backup server, then it is directly disposed as restoring completion status.
Assume that MS1 is restarted in the present embodiment, determining itself has configuration lisp ms-peer 2.2.2.2 and lispms-peer
3.3.3.3, illustrate, MS1 is used as backup MS as main MS, MS2 and MS3, therefore itself is arranged to restart recovery state.
4) when MS1, which is in, restarts recovery state, if the Map-Request message of ITR transmission is received, due to this service
Device do not restart also recovery complete, cannot respond to, at this time by this Map-Request message by encapsulation control information (ECM,
Encapsulated Control Message) encapsulation, it is transmitted to MS2 respectively and MS3 is handled.
MS2 and MS3 can parse the mapping request message by ECM encapsulation, and according to the state of itself by reflecting
It penetrates response message and replies to ITR.ITR only handles the mapping response message that the First backup MS received is sent.If MS2 or
Person MS3, which is in, restores completion status or normal operating conditions, can all solve to the mapping request message by ECM encapsulation
Analysis, and ITR is replied to by mapping response message.If MS2 or MS3, which is in, restarts recovery state, mapping can't be replied
Response message is to ITR.
In this way, when thering is MS to restart, and receiving mapping request message, by forwarding mapping request message to give backup MS,
Backup MS can respond the mapping request message, so that ITR is obtained from the mapping response message that backup MS is replied
The EID-RLOC mapping relations of ETR, so that it is guaranteed that data message realize from the host under ITR to ETR under host forwarding, really
LISP business is protected not interrupt.
In the prior art, the MS restarted can receive mapping logon message, then to receiving after restarting again
Some mapping logon messages also need a longer time, so, it is specifically described below what the preferred embodiment of the present invention was restarted
MS is interacted with backup MS, how to realize fast quick-recovery LISP mapping database.
5) MS1 is configured according to lisp ms-peer, sends a recovery request message to each backup server.For the first time
When sending recovery request message, the initial address of request extends this as 0.0.0.0/0.
The format of recovery request message is as shown in Figure 2.Recovery request message can borrow original Map-Request message
Format increase R (Recover) marker bit by extending reserved marker bit, be shown to be one and restart recovery request message.
Due to be MS send restart recovery request message, do not carry Map-Reply Record.The position of EID-Prefix is filled out
Initial address filled with recovery request message.
6) after backup MS receives recovery request message, recovery state is restarted if be also in itself, does not handle recovery
Request message.
Assuming that backup MS2 and MS3 restores to answer all in recovery state is restarted then replying there will be no backup MS to MS1
Answer message.Therefore, the present invention is arranged itself in MS1 and restores completion timing device for when restarting recovery state, also maintenance one is restarted,
If MS1 is not received by the recovery response message of any backup MS response in the given time, it is determined that restart recovery time-out,
It itself will be set as restoring completion status.
7) after backup MS receives recovery request message, if itself is in recovery completion status, or shape is worked normally
State will reply to the server as main MS and restore response message.Restore response report if there is more backup MS are replied to MS1
Text, MS1 only handle the recovery response message that the First backup MS received is sended over, and avoid handling extra recovery response
Message.
Backup MS is according to the initial address in recovery request message, the LISP mapping database that will locally save, according to reflecting
The size order for penetrating the address EID is sent to the server as main MS by restoring response message, if the LISP locally saved
Mapping database is all sent, then carries in restoring response message and complete marker bit (F).It is connect as the server for main MS
When receiving the recovery response message for carrying completion marker bit (F), determines that the LISP mapping database of main MS is restored to complete, then make
It itself will be set as restoring completion status for the server of main MS.Hereafter, which can normal response
Mapping request message.
It should be noted that being UDP message due to restoring response message, the content of LISP mapping database may need point
Repeatedly send.So received as the server for main MS when not carrying the recovery response message for completing marker bit, it can be after
Continue to backup MS and sends recovery request message, the remainder for the LISP mapping database that request backup MS is saved, until connecing
Receive the recovery response message for carrying and completing marker bit.It is pressed due to carrying in the LISP mapping database restored in response message
According to the size order arrangement of the mapping address EID, so by being filled again to the initial address that backup MS sends recovery request message
The last one the mapping address EID restored in response message was received for last time, judged which is this accordingly in order to back up MS
Remainder in ground LISP mapping database.
The format for restoring response message is as shown in Figure 3.Original Map-Register report can be borrowed by restoring response message
The format of text increases R (Recover) marker bit, is shown to be the response report for restarting recovery by extending reserved marker bit
Text.Increase F (Finished) and complete marker bit, is shown to be the last one and restores response message.EID-Prefix's and Locator
Position is separately filled with the mapping relations of EID-RLOC.
8) preferably, can be pacified when the server as main MS receives recovery response message for security consideration
Full verifying.
Safety verification password is configured on each MS, configuration safety verification password is all identical on each platform.Configuration safety
Verify password implementation can there are many, MS can pass through and configure by lisp ms-peer x.x.x.x order
Lisp map-peer x.x.x.x key, to configure safety verification password.
Server as main MS receives recovery response message, first will be from if safety verification password has been locally configured
Safety verification password is obtained in lisp ms-peer x.x.x.x key configuration order, carries out safe test to response message is restored
Card is verified and is just saved in LISP mapping table database and does not deal with otherwise it is assumed that being attack message.
Safety verification is carried out to response message is restored, specifically can be,
Since the side backup MS is also configured with safety verification password, so in the side backup MS with safety verification password to recovery
Field in response message carries out cryptographic calculation, obtains encrypted message (Authentication Data), which is taken
Band is sent to the server as main MS in restoring response message.The recovery of backup MS is received as the server for main MS
It when response message, is decrypted to carrying in the encrypted message restored in response message, determines the safety that the side backup MS is configured
When verifying password is consistent with the safety verification password that main MS is configured, determination is verified.
It should be noted that restoring completion status when MS is in, so that it may respond mapping request message.Only this two
In the case of kind, if situation one, MS1 do not have lisp ms-peer configuration, illustrates that no MS backup server exists, then directly set
It is set to recovery completion status.If situation two, MS1 are not received by the recovery response of any backup MS response in the given time
Message, it is determined that restart recovery time-out, itself will be set as restoring completion status.Not due to LISP mapping database at this time
Entirely, it is possible to the EID-RLOC mapping relations of ETR can not be found, MS1 can respond the response of Negative type at this time.
Based on same inventive concept, the present invention also proposes that mapping server restarts recovery device in a kind of LISP, referring to
Fig. 4, Fig. 4 are the apparatus structure schematic diagram for being applied to the above method in the specific embodiment of the invention.The device is applied to reflect with master
Penetrate the i.e. main MS of MS that server MS identity is restarted, comprising:
Retransmission unit 401 is received, receives tunnel router TR transmission in the main MS for restarting recovery state for working as
When mapping request Map-Request message, according to the address of itself preconfigured other backups MS by the mapping request message
It is transmitted to backup MS, so that backup MS replys the mapping request message of the TR by mapping response message.
The main MS receive tunnel router TR transmission mapping request Map-Request message before, the device into
One step includes judging setting unit 402: determining whether itself is provided with the address of other backups MS in advance, if it is, setting
It itself is to restart recovery state；If it is not, then itself is arranged to restore completion status.
The reception retransmission unit 401 is also used to: recovery request message is sent to backup MS, so that backup MS is by local guarantor
The LISP mapping database content deposited responds to main MS by restoring response message；The LISP mapping database includes multiple
The mapping relations of endpoint identifier EID and route location identifier RLOC.
If the main MS is not received by the recovery response message of any backup MS response in the given time, described to sentence
Disconnected setting unit 402 is also used to: being determined and is restarted recovery time-out, itself will be set as restoring completion status.
The judgement setting unit 402 is also used to: carrying the recovery response for completing marker bit when the main MS is received
When message, determines that the LISP mapping database of itself is restored to complete, then itself will be set as restoring completion status；As the main MS
When receiving the recovery response message for not carrying completion marker bit, recovery request message is sent to backup MS again, is requested standby
The remainder for the LISP mapping database that part MS is saved, until receiving the recovery response report for carrying and completing marker bit
Text.
The device further comprises decryption processing unit 403:
When receiving the recovery response message of backup MS, according to the safety verification password that itself is configured, to carrying extensive
Encrypted message in multiple response message is decrypted, and determines the peace of the safety verification password that the side backup MS is configured and main MS configuration
When verifying password is consistent entirely, the LISP mapping database restored in response message is saved；Otherwise, the recovery response is abandoned
