Detailed description of the invention
In order to realize the object of the invention, the core concept that the present invention uses is: be previously stored virtual machine in network management system
ID and corresponding VLAN configuration information；When network management system perceives the network migration event of virtual machine, move into virtual machine
The ascending physical signal switch that physical server is corresponding issues the VLAN configuration of this virtual machine, after virtual machine (vm) migration completes, moves into
Physical server by send RARP message make local edge switch, gateway switch and between all physics hand over
The ARP table changed planes is updated, and then makes all ascending physical signal switches of this physical server moved into all get this
The latest configuration of virtual machine.Owing to the virtual machine on all ascending physical signal switches of the physical server moved into normally accesses net
The ARP table of network is updated, thus virtual machine can normally access network.
For making technical solution of the present invention more clear and understanding, below in conjunction with the specific embodiment of the invention in addition specifically
Bright.As in figure 2 it is shown, configure the method flow diagram of dynamic migration for VLAN of the present invention.Wherein said method is applied and is at least being included
In the network system that two physical servers and ascending physical signal switch thereof are constituted, wherein said every physical server can root
According to needs, virtual turn to multiple different virtual machine.Mainly comprise the steps:
Step 1, the corresponding relation being previously stored in network management system between ID and the VLAN configuration information of virtual machine.
Specifically, in embodiments of the present invention, network management system can by the modes such as poll obtain each virtual machine ID with
Corresponding relation between VLAN configuration information.Wherein said virtual machine ID is specifically as follows the MAC Address of this virtual machine, IP address or
Person other can uniquely identify the information of this virtual machine.In the corresponding pass obtained between ID with the VLAN configuration information of all virtual machines
After system, network management system also needs to store this corresponding relation further, as stored by modes such as forms.
As a example by VLAN configuration information corresponding for the VM1 shown in Fig. 1 is as VLAN1, network management system is obtaining this corresponding relation
After, by the corresponding relation between ID and the VLAN1 configuration information of record VM 1.
Step 2, when network management system perceives the network migration event of virtual machine, the physical server moved into virtual machine
Corresponding ascending physical signal switch issues the VLAN configuration of this virtual machine.
Specifically, when resource (including CPU, internal memory, disk and network throughput etc.) in certain physical server running
When bottleneck occurring or breaks down, need the virtual machine (vm) migration of operation on this physical server to other physical server
On, thus reach the purpose of load balancing and efficent use of resources.When virtual machine occurs to migrate, network management system can detect that this
The ID letter of migration event, the ID then directly obtaining the virtual machine of migration according to this migration event and the physical server moved into
Breath.Described network management system obtains, according to the ID of this virtual machine, the VLAN configuration information that this virtual machine is corresponding, according to the physics moved into
The id information of server is searched the network equipment topological relation stored and is obtained the ascending physical signal switch of this physical server of moving into
Corresponding port.The VLAN configuration information of this virtual machine is then handed down to ascending physical signal corresponding to the physical server moved into hand over
Change planes on the port of correspondence.
It should be noted that in order to realize the present invention, preferably embodiment is that described network management system is to physics clothes of moving into
The port corresponding to ascending physical signal switch of business device issues the VLAN configuration information of this migration virtual machine will moving prior to virtual machine
Shifting completes.So, after virtual machine (vm) migration completes, the physical server moved into sends RARP to its gateway physical switches
(Reverse Address Resolution Protocol, reverse address resolution protocol) message, wherein carries the IP of virtual machine
The information such as address and MAC Address so that local edge switch, gateway switch and between all physical switches
ARP table is updated, and then makes all ascending physical signal switches of this physical server moved into all get this virtual machine
Latest configuration.
If after virtual machine (vm) migration completes, described network management system just completes to hand over to the ascending physical signal of physical server of moving into
Corresponding ports of changing planes issues the VLAN configuration information of the virtual machine of migration, and now, RARP message will be unable to be taken by physics of moving into
The ascending physical signal switch of business device.As another implementation in the present invention, network management system can pass through network topology
Calculate the information of the gateway switch at the physical server place moved into.Further, described network management system by SNMP or
ARP table in order line aging gateway physical switches, and by described gateway physical switches to the physical server moved into
The edge switch at place sends probe messages, when after the message response receiving edge switch, shows described edge switch
With the ARP table in gateway switch and all physical switches between them is all updated, all get virtual machine
Latest position, described virtual machine and then external network can be accessed.
Still as a example by the application scenarios shown in Fig. 1, if there is bottleneck in physical server A resource in running, this
Time, need to move on physical server B by the VM 1 on this physical server A, now, network management system is according to the migration of VM 1
Event can obtain the mac address information of ID(for example, this virtual machine of this VM 1) and the ID letter of the physical server B that moves into
Breath.Id information according to this VM 1 obtains the VLAN configuration information VLAN1 of this VM 1 correspondence further, according to physical server B
Id information search the network equipment topological relation of storage and obtain ascending physical signal switch (the Edge Switch of physical server B
2) port Ethernet 2/1.Finally, VLAN configuration information VLAN1 corresponding for the VM1 of acquisition is handed down to move by described network management system
Ascending physical signal switch corresponding for physical server B (the Edge Switch 2) port Ethernet 2/1 entered.
When network management system is to ascending physical signal switch corresponding for physical server B (Edge Switch2) port moved into
Ethernet2/1 issues the VLAN configuration information VLAN1 of VM1 when completing prior to virtual machine (vm) migration action, with the application shown in Fig. 1
As a example by scene, after virtual machine VM1 completes to migrate, the physical server B moved into is further to its up gateway physical exchange
Machine sends RARP(Reverse Address Resolution Protocol, reverse address resolution protocol) message, at this RARP
Message carries the VLAN configuration information VLAN1 of this virtual machine so that local edge switch (Edge Switch2), gateway are handed over
Change planes and between all physical switches (not shown) by study obtain this virtual machine VLAN configuration information, and
Make respective ARP table be updated, and then all ascending physical signal switches of this physical server B moved into all are got
The latest configuration of this virtual machine.
If after virtual machine (vm) migration completes, described network management system just completes the ascending physical signal to the physical server B that moves into
Switch corresponding ports issues the VLAN configuration information of the virtual machine of migration, and now, RARP message will be unable to the limit by moving into
Edge switch (Edge Switch 2 as shown in Figure 1).As another implementation in the present invention, network management system
First pass through the information that network topology calculates the gateway switch at the physical server B place moved into.Further, described net
Guard system passes through the ARP table in SNMP or order line this gateway physical switches aging, and by described gateway physical switches
Edge switch (Edge Switch2) to the physical server B place moved into sends probe messages, when receiving edge exchange
After the message response of machine Edge switch, show described edge switch and gateway switch and the property between them
