Determine method and the device of host migration state
Technical field
The application relates to LISP, and (Locator/IdentitySeparationProtocol, position separates with markAgreement) technical field, relate in particular to method and the device of in LISP network, determining host migration state.
Background technology
LISP provides a kind of novel network architecture, and IP address is divided into two independently address spaces:EID (EndpointIdentifier, Endpoint ID) and RLOC (RoutingLocator, route positionSymbol). EID is the host address of communication end point, realizes identically with existing, and the effect in LISP is similarIn DNS (DomainNameSystem, domain name system), have independently space. At LISP netIn network, EID can be independent of RLOC and move; RLOC is the address of LISP router, can beRouting forwarding in existing Internet, can overall route. The message of communicating by letter between EID is encapsulated in RLOCBetween tunnel in forward.
Fig. 1 is LISP network panorama schematic diagram, and as shown in Figure 1, LISP assembly is as follows:
1) xTRs (xTunnelRouters): tunnel router, comprising: ITR (IngressRouter,Entrance TR) and ETR (EgressTR, outlet TR);
On all ETR of each LISP website, safeguard and have the EID of this website and the mapping of RLOC to closeSystem, ETR periodically sends to the mapping relations of the EID of this website and RLOC by logon messageMS。
2) MapDB (MapDataBase, mapping database): EID is to the mapping (enum) data of RLOCStorehouse, the mapping relations that comprise RLOC and EID, are stored in mapping server (MS, MapServer)On;
MS receives the logon message that ETR sends, by the mapping relations of the EID in message and RLOCBe stored in MapDB.
3) PxTR (ProxyxTR): act on behalf of xTR, be positioned at the net of supporting LISP and not supporting LISPNetwork boundary.
LISP has realized separating of core net and edge net with ETR by ITR, it is by a mappingThe mapping that system is used for realizing from EID to RLOC is resolved. LISP is by encapsulation and the deblocking of IP-in-IPInstallation system has realized route and the forwarding in core net.
Taking Fig. 1 as example, when the main frame 1 in LISP website A sends to the main frame 2 in LISP website BWhen data, the EID of main frame 2 is non-routable in core net; When packet arrives after ITR, ITRFind local RLOC corresponding to EID that does not preserve main frame 2, to MR, (MapResolver reflectsRadiolysis parser) send Map-Request message to inquire about the RLOC corresponding to EID of main frame 2, MRMap-Request message is transmitted to MS, and MS finds the EID of main frame 2 in local MapDBThe RLOC of corresponding ETR, Map-Request message is transmitted to ETR by MS, and ETR is by main frame 2EID and oneself RLOC be carried in Map-Response message and return to ITR; Then ITREncapsulate this packet, taking oneself RLOC as source address, taking the RLOC of opposite end ETR as destinationLocation, the mapping relations of simultaneously preserving the EID of main frame 2 and the RLOC of ETR; Opposite end ETR receives thisBag after this bag of decapsulation, finally by Packet Generation to main frame 2.
In LISP network, main frame can move, as shown in Figure 2, and vCenter (virtual center)Control the migration of VM (VirtualMachine, virtual machine), establish at a time, vCenter determinesVMB is moved to DC2 from DC (DataCenter, data center) 1, concrete transition process asUnder:
1) VMB moves to DC2 from DC1, and ETR4 receives the gratuitous ARP (Address that VMB sendsResolutionProtocol, address resolution protocol) message or data message, thus ETR4 perceivesVMB moves under this ETR;
2) ETR4 notifies VM by multicast Notify message to other ETR (ETR3) of these two layers of netsThe B DC2 that moves into, and by registration message the EID to MS registration VMB;
3) MS, according to the EID of VMB in local MapDB, finds corresponding the moving out of VMBThe RLOC of ETR:ETR2, sends Map-Notify message informing VMB to ETR2 and moves out;
4) ETR2 receives after this Map-Notify message, and the state of VMB is made as: move out, and willThis Map-Notify message is broadcasted in these two layers of nets;
5) after ETR2 receives that object is the data message of VMB, to the far-end TR that sends this messageInitiate SMR (SolicitMap-Request, mapping request is initiated in request) message, in this SMR messageCarry the EID of VMB, again go for to trigger this far-end TR the RLOC that moves into that asks VMB corresponding,Abandon this data message simultaneously;
6) far-end TR receives this SMR message, initiates to carry VMB to MR (mapping resolver)The Map-Request message of EID, Map-Request message is transmitted to MS by MR, MS is at thisGround finds the RLOC of the ETR4 that moves into that the EID of VMB is corresponding in MapDB, and MS willMap-Request message is transmitted to ETR4, and ETR4 is by the RLOC's of the EID of VMB and ETR4Mapping relations are carried in Map-Response message and return to far-end TR, and far-end TR closes with this mappingThe EID of former VMB that system's renewal self is preserved and the mapping relations of the RLOC of ETR2, after this, shouldThe message taking VMB as object that far-end TR sends is no longer issued ETR2, but issues ETR4, streamAmount has been moved.

Detailed description of the invention
Applicant analyzes the host migration process in existing LISP network, finds to exist as followsProblem:
Taking Fig. 2 as example, when VMB is from DC1 moves to DC2, ETR2 need to record VMB'sState is: moves out, if VMB moves back to DC1 from DC2 again afterwards, now, note before ETR2 inquiryThe state of the VMB of record, is found to be and moves out, and determines that this VMB moves into for moving out again, and will rememberThe state of the VMB of record is updated to: move out and move into.
When having VM to move out or moving out while moving into again, the state that ETR must accurate recording VM, so thatETR carries out different processing for different states, thereby the MapDB's that guarantee MS safeguards is accurateProperty. Still taking Fig. 2 as example, in VMB transition process, the mapping relations in the MapDB of MSChange as follows:
A, after ETR2 starts, can, according to the EID network segment of original support of self configuration, send out to MSSend registration message, this registration message carry this original support the EID network segment (taking IPv4 address as example,The EID network segment is 24bit), the MapDB of MS has just preserved RLOC and the ETR2 of ETR2 like thisThe mapping relations of the EID network segment of original support;
B, after this, can be to MS after VMB is from ETR2 moves to ETR4, and ETR4 perceivesSend registration message, this message carry VMB EID (taking IPv4 address as example, the EID of VMBFor 32bit), MS receives that, after this registration message, the EID of the VMB carrying according to this message is at MapThe mapping relations that find coupling in DB (are the RLOC of ETR2 and the EID of the original support of ETR2The mapping relations of the network segment), find that the EID of the VMB that this message carries is better than in the mapping relations of couplingThe EID network segment of the original support of ETR2, upgrade with the EID of VMB reflecting of mating in MapDBPenetrate the EID network segment of the original support of ETR2 in relation;
Meanwhile, ETR2 receives after the Map-Notify message that MS sends, can be by the state of VMBBe made as: move out;
C, in the time that VMB moves back to ETR2 again, ETR2 is according to the state of the VMB of step b record:Move out, can learn that this VMB is actually to move out to move into again, upgrade the state of VMB for moving outMove into, send registration message to MS, this registration message carries the EID of VMB (with IPv4 addressFor example, the EID of VMB is 32bit), MS receives after this registration message, carries according to this messageThe mapping relations that the EID of VMB finds coupling in MapDB (are EID and the ETR4 of VMBThe mapping relations of RLOC), and find the EID of VMB and the RLOC of ETR2 that this message is carriedMapping relations priority higher than coupling mapping relations (in two mapping relations, the length of EID is identical,But the time of the mapping relations in registration message upgrades), the EID of the VMB carrying with this messageUpgrade the mapping relations of mating in MapDB with the mapping relations of the RLOC of ETR2.
From step c, if VMB moves out after ETR2, because ETR2 such as restarts at the reason, causeThe state of the VMB of the upper record of ETR2 is the information dropout of moving out, and after this VMB moves back to ETR2 againAfter, ETR2 just thinks that VMB moves into for the first time, and that the EID of ETR2 belongs to ETR2 is originalThe EID network segment of supporting, therefore can be made as the state of VMB: online, and can not register ETR2 to MSEID because: ETR2 has registered the EID network segment of original support, this in the time starting to MSSample, the mapping relations of preserving in the MapDB of MS remain the EID of VMB and the RLOC of ETR4Mapping relations, obviously, these mapping relations of preserving in the MapDB of MS are wrong, thus meetingCause issuing the traffic loss of VMB.
In actual applications, network condition and main frame situation cannot ensure, for example: if VMBWhen moving out after ETR2 but also not moving back to, ETR2 has occurred to restart, cause ETR2 upper before recordThe status information of moving out of VMB is lost, after ETR2 is restarted like this, and when VMB moves back to ETR2, willCause ETR2 to think that mistakenly the state of VMB is online instead of moves out and move into, thereby cause sending outToward the traffic loss of VMB; Or, if network concussion in VMB transition process causes ETR4Or the map-notify information drop-out that ETR2 sends, also can cause the upper record of ETR3, ETR1The mapping relations mistake of the EID of VMB and RLOC, thus cause mailing to the traffic loss of VMB.
The method flow diagram of definite host migration state that Fig. 3 provides for the application one embodiment, it specifically walksRapid as follows:
In a kind of embodiment, needing the host address of observing is the address of the main frame of the upper original lower extension of ETR.
Step 301:ETR receives the Map-Notify message that MS sends, and finds the EID that this message is carriedFor user configured host address, and the RLOC that this message is carried is for the RLOC of this ETR, trueFixed this main frame is moved out from this ETR, and the EID of this main frame is put into non-volatile memory medium, and reallyThe state of recognizing this main frame is: move out.
In a kind of embodiment, user configured host address be the upper original lower extension of ETR and there is migrationThe address of the main frame needing.
Non-volatile memory medium refers in the time of ETR power-off, in this non-volatile memory medium, storesInformation still can not be lost, and modal non-volatile memory medium is as flash memory.
In a kind of embodiment, for the EID of this main frame in non-volatile memory medium arranges ageing time,Therein in a kind of implementation, this ageing time can equal every EID in the MapDB of MSAgeing time with the mapping relations of RLOC.
Step 302:ETR detects when main frame is moved into, if find this in non-volatile memory mediumThe EID of main frame deletes the EID of this main frame in non-volatile memory medium, and confirms this main frameState be: move out and move into again.
In a kind of embodiment, in step 301, at ETR, the EID of this main frame is put into non-volatile depositingIn storage media time, further by this EID, the access interface correspondence on this ETR is put into non-volatile depositingIn storage media;
And in step 302, ETR detects that main frame is moved into and comprises:
For EID and the access interface of each main frame in non-volatile memory medium, ETR is from this accessInterface periodically outwards sends probe messages, if receive detection response message from this access interface,Determine that this EID respective hosts moves into, or ETR receives the VM that virtual center vCenter sendsThe notice of moving into, this notice is carried the EID of the main frame of moving into, and determines that this EID respective hosts moves into;
And, in step 302, at ETR, the EID of this main frame is deleted in non-volatile memory mediumTime, further the access interface of this main frame is deleted in non-volatile memory medium.
In a kind of embodiment, probe messages is as ARP (AddressResolutionProtocol, addressAnalysis protocol) request message, or ping message.
In a kind of embodiment, ETR receives VM that vCenter the sends notice of moving into, further from answeringPosition application interface (resetapi) receives.
To adopt flash memory as non-volatile memory medium as example, the application is elaborated below:
The method flow diagram of definite host migration state that Fig. 4 provides for another embodiment of the application, it is concreteStep is as follows:
Step 400: that user configures original lower extension on this ETR on ETR and exist migration to needThe address of VM.
User has configured behind address original lower extension and the VM that existence migration needs on ETR, joinsCorresponding the original of VM in each VM address of putting is this ETR at line position.
In practical application, the address upper original lower extension of ETR and the VM that existence migration needs can beAn address space can be also the set of one or more addresses.
Step 401:ETR finds that there is VM and reaches the standard grade, and the address of this VM is user configured VM groundLocation, confirms that the state of the user configured corresponding VM in this VM address is: online.
The judgment mode that VM reaches the standard grade is as follows:
When ETR is when an interface receives ARP message (comprising gratuitous ARP packet), from ARPIn message, read sendIP address, if this sendIP address belongs to user configured VM address, recognizeFor having VM, this interface reaches the standard grade;
Or, when ETR receives IP message from an interface, read the source IP address of IP message, ifThis source IP address belongs to user configured VM address, thinks that this interface has VM to reach the standard grade.
Step 402:ETR receives the Map-Notify message that MS sends, and finds the EID that this message is carriedFor user configured VM address, and the RLOC that this message is carried is for the RLOC of this ETR, trueFixed this VM moves out, using the access interface of the EID of this VM and this VM as a new VM that moves outList item is put into the VM list of moving out of self flash memory, and confirms that the state of this VM is: move out.
The access interface of the EID of VM and this VM is put into the VM list of moving out of flash memory, just tableShow this VM this ETR that moved out.
Step 403: for each list item of moving out in VM list in self flash memory, ETR was according to shouldAccess interface in list item, periodically sends probe messages from corresponding interface.
Probe messages is as ARP request message, ping message etc.
Step 404: in the time that ETR receives detection response message from arbitrary interface, think this interface correspondenceVM moved back to again this ETR, by the access interface of the EID of this VM, this VM from self flash memoryIn the interior VM list of moving out, delete, confirm that the state of this VM is: move out and move into again simultaneously.
After ETR power-off, the information in flash memory can not be lost, still can retain, therefore, when ETR occursWhile restarting, still can be for every the list item of moving out in VM list in flash memory, periodically after restartingGround sends probe messages from corresponding interface, thereby has ensured the accuracy of the state of the VM of ETR maintenance.
In addition, due to every mapping relations in the MapDB of MS have an ageing time as: 24Hour, therefore, accordingly, in the embodiment of the present application, can be the VM row of moving out in the flash memory of ETREvery list item in table arranges an ageing time, the mapping in the MapDB of this ageing time and MSThe ageing time (being generally 24 hours) of relation is identical, when the ageing time of list item arrives constantly, by this tableEntry deletion.
In actual applications, step 403～404 can replace with:
Step 403: in the time that vCenter determines that a VM moves into an ETR, by self and this ETR itBetween resetapi send the VM notice of moving into this ETR, this notice is carried the EID of this VM.
Step 404: this ETR receives this VM notice of moving into, the VM row of moving out in self flash memoryIn table, search the EID of the VM that this notice carries, if find, by the table corresponding EID of this VMThe VM list of moving out of item in flash memory, delete, confirm that the state of this VM is: move out and move into again simultaneously.
Below provide the application's application example:
Still, taking Fig. 2 as example, VMA, the VMB network segment under ETR2 is online, wherein, and VMAAddress be 1.1.1.100/32, the address of VMB is 1.1.1.200/32, VMB connecing on ETR2Incoming interface is g0/0, and user thinks that VMA, VMB exist migration needs, configure on ETR21.1.1.100/32、1.1.1.200/32。
Step 01: when VMB move to other ETR as: when ETR4, ETR2 can receive that MS sends outThe Map-Notify message of coming, this message is carried the mapping pass of the EID of VMB and the RLOC of ETR4System, ETR2 learns that VMB moves out, by two tuples 1.1.1.200/32, g0/0} is recorded to flash memory, andThe state of confirming VMB is: move out;
Step 02:ETR2 periodically sends ARP request message or Ping message from interface g0/0;
Before VMB moves back to ETR2, even if ETR2 has occurred to restart, due to two tuples in flash memory1.1.1.200/32, and g0/0} still can retain, and therefore, after restarting, ETR2 can continue periodically from connecingMouth g0/0 sends ARP request message or Ping message;
Step 03: in the time that ETR2 receives arp response message or ping message from interface g0/0, recognizeFor VMB moves back to, by two tuples, { 1.1.1.200/32, g0/0} deletes from flash memory, and confirms VMBState be: move out and move into again.
Above-mentioned steps 02～03 is also replaceable is:
Step 02: in the time that keeper controls vCenter VMB is moved to ETR2, vCenter callsThe restapi interface that ETR provides, carries the EID:1.1.1.200/32's of VMB to ETR2 transmissionThe VM notice of moving into.
Step 03:ETR2 receives this notice, and by two tuples in flash memory, { 1.1.1.200/32, g0/0} deletesRemove, and confirm that the state of VMB is: move out and move into again.
The beneficial effect of the embodiment of the present application is as follows:
By in the time that VM moves out, the EID of VM is put into non-volatile memory medium by ETR, makesAfter ETR is restarted, still can correctly detect the own migration role for this VM, strengthen migration steadyQualitative.
