See Fig. 1, the application scenarios schematic diagram for application embodiment of the present invention virtual machine (vm) migration:
A kind of group-network construction of LISP network has been shown in Fig. 1.This framework comprises: the first data center, the second data center, mapping server and far-end server.Wherein, LISP network also can comprise other data centers except the first data center and the second data center, just for the first data center and the second data center in the embodiment of the present invention, the virtual machine migration method that the present invention proposes is described.In addition, mapping server can independently and outside each data center, also can be positioned in one of them data center.
In addition, all there are router in first data center and the second data center, and each router all can carry out LISP tunnel encapsulation (Ingress Tunnel Router, ITR) and LISP tunnel decapsulation (Engress Tunnel Router, ETR) to data message.Each data center can comprise one or more virtual machine, and the virtual machine of each data center may move, such as: the virtual machine of the first data center can move to the second data center.
In prior art, when virtual machine is from after the first data center LISP network moves to the second data center, and far-end server learn virtual machine move into the second data center routing address before, when far-end server sends datagram to the virtual machine of having moved out of the first data center, the data message that the virtual machine that this can have been moved out according to the NULL0 route generated of the router of the first data center is corresponding abandons, thus make in virtual machine (vm) migration process, flow between far-end server and virtual machine there will be short interruption, reduce Consumer's Experience.
Which and in the embodiment of the present invention, in virtual machine (vm) migration process, user can know which virtual machine needs migration, and need to move to destination.Wherein, user is network manager, and can the position of each virtual machine in overall arrangement LISP network.Therefore, when virtual machine VM needs to move to the second data center LISP network from the first data center, user can configure the forwarding route corresponding to virtual machine of these needs migration according to the host address of virtual machine and the router address of the second data center needing migration, and the forwarding route of this configuration is sent to the router of the first data center, to make this router by the forwarding route sending-down that receives in local routing table, and for when receiving the data message for the virtual machine after migration that far-end server sends, then according to forwarding route corresponding to this virtual machine user configured by the virtual machine after data message forwarding to migration, thus achieve in virtual machine (vm) migration process, flow between far-end server and the virtual machine after moving there will not be short interruption, and then improve Consumer's Experience.
Be described in detail below in conjunction with the embodiment of accompanying drawing to virtual machine (vm) migration of the present invention.
See Fig. 2, be an embodiment flow chart of virtual machine migration method of the present invention, this embodiment is applied on the router of the first data center in LISP network, and this first data center can be the first data center in Fig. 1, comprises the following steps:
Step 210: when virtual machine needs to move to the second data center LISP network from the first data center, accept the forwarding route to the virtual machine configuration needing to move, this forwarding route configures according to the host address of the virtual machine needing migration and the router address of the second data center.
In the present embodiment, user can the position of each virtual machine in overall arrangement LISP network.When determining a virtual machine to move to the second data center from the first data center, in order to ensure in virtual machine (vm) migration process, flow between far-end server and the virtual machine after moving there will not be short interruption, user can forward route for this virtual machine configures one, for when virtual machine is from after the first data center moves to the second data center, far-end server learn to move into the second data center virtual machine new route before, far-end server is still according to the router address that this locality is preserved, the data message of the virtual machine that migration occurs will be sent to the router of the first data center, and the router of the first data center receive for occur move virtual machine data message after, can according to user configured forwarding route by this data message forwarding to the virtual machine of the second data center of having moved into.
Step 220: according to the router interface address of the first data center with need the host address of the virtual machine of migration to arrange the mask-length of forwarding route corresponding to the virtual machine of these needs migration, and the forwarding route sending-down after mask-length will be set in local routing table.
In the present embodiment, after user configures corresponding forwarding route, and the host address of the virtual machine of migration can be needed whether to be in the mask-length that the same network segment arranges this forwarding route according to the router interface address of the first data center, and the forwarding route sending-down of mask-length will be set in local routing table, the virtual machine moved if now need also is not moved out from the first data center, then not only comprise the forwarding route that the virtual machine of needs migration is corresponding in local routing table, also comprise address resolution protocol (the Address Resolution Protocol that the virtual machine of these needs migration is corresponding, ARP) Host routes.This ARP Host routes is used for before the virtual machine of needs migration is moved out from the first data center, when receiving the data message of the virtual machine for needs migration that far-end server sends, according to ARP Host routes, data message is sent to the virtual machine of these needs migration.
Step 230: when receiving the data message of the virtual machine for needs migration that far-end server sends, and the virtual machine of these needs migration is when moving to the second data center from the first data center, then according to forwarding route corresponding to the virtual machine of these needs migration in local routing table by the data message forwarding received to the virtual machine of the second data center of moving into.
In the present embodiment, during the data message of the virtual machine after the migration that the router of the first data center receives, the router of data message forwarding to the second data center that will be able to receive according to the forwarding route of this virtual machine in local routing table, virtual machine after data message forwarding extremely being moved by the router of the second data center again, there will not be interruption to make the flow between far-end server and the virtual machine after moving.
The forwarding route related in above-mentioned steps 210 to step 230 can comprise: prefix addresses and next hop address.Prefix addresses is according to needing the network segment address that the host address of the virtual machine moved is corresponding, and next hop address is router address and the destination address of the second data center.
In addition, when the mask-length of the forwarding route corresponding to virtual machine of these needs migration is set according to the router interface address of the first data center and the host address of virtual machine in above-mentioned steps 220, whether the host address of the virtual machine that can move according to the router interface address of the first data center and needs is in the same network segment is carried out different settings, specific as follows:
When the router interface address of the first data center and the host address of virtual machine are in the same network segment, then belonging to the router interface address that the mask-length of the forwarding route that the virtual machine moved by these needs is corresponding is arranged on the first data center between the network segment and the host address of virtual machine.
Or, when the router interface address of the first data center and the host address of virtual machine are not in the same network segment, then between the transportable virtual machine network segment that the mask-length of the forwarding route that the virtual machine moved by these needs is corresponding is arranged on the router interface configuration of the first data center and the host address of virtual machine.
Such as: the host address needing the virtual machine moved in the first data center is 10.17.1.65/32 and ARP Host routes, and its mask-length is 32.
Further, when the router interface address of the first data center with when needing the host address of the virtual machine of migration to be in the same network segment, this network segment is 10.17.1.0/24, and its mask-length is 24; Or, when the router interface address of the first data center with when needing the host address of the virtual machine of migration not to be in the same network segment, the router interface of the first data center is configured with the transportable virtual machine network segment, and this network segment is 10.17.1.0/24, and its mask-length is 24.
Further, the router address of the second data center is 192.168.2.1, then the user configured prefix needing the forwarding route of the virtual machine of migration can be 10.17.1.0/25, and next hop address is 192.168.2.1.
Wherein, 25 in 10.17.1.0/25 is mask-length, this prefix mask length can between 24 to 32 any value.
If select mask-length to be 24, then can overlap with this router interface address, cause occurring that configuration does not come into force, the direct-connected routing priority of 24 is not high.
If select mask-length to be 32, owing to forwarding the priority of route higher than ARP Host routes, then can cover ARP Host routes, cause when the virtual machine of needs migration does not move, the data message received also can be sent to the second data center according to forwarding route, causes flow obstructed
So, when receiving the data message of the virtual machine for needs migration that far-end server sends, and the virtual machine of these needs migration is also when moving out from the first data center, then the longlyest in local routing table can match ARP Host routes 10.17.1.65/32, and data message is sent to the virtual machine of not moving out, can proper communication, when receiving the data message of the virtual machine for needs migration that far-end server sends, and the virtual machine of these needs migration is when moving to the second data center from the first data center, without ARP Host routes and 10.17.1.65/32 in local routing table, then in local routing table, the longest matching can forward route and 10.17.1.0/25, thus next hop address data message is sent in forwarding route and 192.168.2.1, thus make the virtual machine after moving also can receive data message, achieve in virtual machine (vm) migration process, flow between far-end server and the virtual machine of migration there will not be interruption, and then improve Consumer's Experience.
As seen from the above-described embodiment, when virtual machine needs to move to the second data center LISP network from the first data center, acceptance is to the forwarding route of virtual machine configuration, and this forwarding route configures according to the host address of the virtual machine needing migration and the router address of the second data center, the mask-length of this forwarding route is set, and by the forwarding route sending-down after described setting in local routing table, when receiving the data message of the virtual machine for needs migration that far-end server sends, and the virtual machine of these needs migration is when moving to the second data center from the first data center, then according to the forwarding route corresponding to virtual machine of these needs migration in local routing table by the data message forwarding received to the virtual machine of the second data center of moving into, thus to achieve the data message forwarding received by user configured forwarding route to the virtual machine of moving out, can ensure in virtual machine (vm) migration process, flow between server and the virtual machine after moving there will not be short interruption, and then improve Consumer's Experience.

Step 310: after virtual machine moves to the second data center from the first data center, receive the mapping notice message that the virtual machine of this generation migration that mapping server sends is corresponding, and generate the packet loss route corresponding to virtual machine of this transmission migration according to this mapping notice message.
Step 320: by packet loss route sending-down in LISP thread.
Step 330: when receiving the data message for this virtual machine moved that far-end server sends, request corresponding to virtual machine generating this generation migration according to the packet loss route in LISP thread sends mapping request (Solicit Map-Request, SMR) message.
Step 340: SMR message is sent to far-end server, after receiving SMR message, sends mapping request message, for relearning the route of the virtual machine after migration to mapping server to make far-end server.
The packet loss route related in above-mentioned steps 310 to step 330 is the NULL0 route that the router of the first data center generates.In order to this NULL0 route only triggers SMR message, and the data message received is not forwarded, this NULL0 route is then needed only to be issued in LISP thread, and be issued to no longer further in local routing table, when this packet loss route only receives for the router of the first data center the data message for this virtual machine moved that far-end server sends like this, trigger the SMR message that the virtual machine of this generation migration is corresponding.
As seen from the above-described embodiment, when receiving the data message for this virtual machine moved that far-end server sends, SMR message can be triggered according to the packet loss route in LISP thread, and make the far-end server of the SMR message received relearn the route of the virtual machine after migration, simultaneously, according to the forwarding route in local routing table by data message forwarding to the virtual machine of the second data center of moving into, thus while the flow that ensure that between far-end server and the virtual machine of migration there will not be interruption, the route that far-end server relearns the virtual machine after migration can also be triggered.In addition, after far-end server learns the route of the virtual machine after moving, new route can be utilized to send datagram to the virtual machine after migration.
