S304: controller carries out IP migration control according to calculated result.
IP migration includes moving caused by the migration of single ip address, the migration of entire virtual port and virtual machine capacity reducing
It moves, specifically,
The migration schematic diagram of single ip address as shown in Figure 5, it is minimum in comprehensive evaluation value, and move out lower than all nodes
Threshold value (if in view of with mean value difference it is little there is no need to migrate, therefore preferably 0.9 times of mean value) VPort in successively
Using the minimum IP address of evaluation of estimate as migrating objects, moves to evaluation of estimate and be higher than and move into threshold value (if considered and equal value difference
It is not little there is no need to move into, therefore preferably 1.1 times of mean value) VPort in, resurvey QoS, score again, until
Not less than moving out threshold value, migration while, needs to notify related protocol stack managing process inside empty machine all VPort evaluations of estimate, into
Row protocol stack resource updates.
The migration schematic diagram of virtual port as shown in connection with fig. 6 it is found that if when carrying out single IP migration as shown in Figure 5, if
All VPort evaluations of estimate are unable to reach not less than this requirement of threshold value of moving out, then consider bulk migration to other physical network card
On, as shown in Figure 6.Specifically, sometimes leading to certain network interface card Physical Networks due to load unevenness between different physical network cards
The QOS for blocking itself is of low quality, thus the QOS of interchanger entirety is of low quality, and single ip address as shown in Figure 5 is in same object
Manage migration between the empty port of network interface card and the purpose for promoting QOS be not achieved, attempt can not to reach according to Fig. 5 migration it is expected after, need
It is minimum in comprehensive evaluation value according to taking shown in Fig. 6, and threshold value is moved out (if considered and mean value difference lower than all nodes
It is little there is no need to migrate, therefore preferably 0.9 times of mean value) physical network card in the minimum VPort of evaluation of estimate as migration
Object, bulk migration to evaluation of estimate be higher than move into threshold value (if in view of with mean value difference it is little there is no need to move into, therefore compared with
Good is 1.1 times of mean value) physical network card in, resurvey QoS, score again, until all empty ports evaluations of estimate are not less than
It moves out threshold value, migration while needs to notify related protocol stack managing process inside empty machine, carries out protocol stack resource updates.
The schematic diagram of virtual machine capacity reducing as shown in connection with fig. 7 is it is found that if a certain empty machine of empty machine control node decision needs
Capacity reducing, IP address all on the void machine will move in the physical bridge of other empty machines before capacity reducing, and IP address migration needs
It completes one by one, and follows same principle, thereon the minimum IP address priority migration of the evaluation of estimate VPort high to evaluation of estimate, so
After recalculate evaluation of estimate, again to the highest VPort migration of new evaluation of estimate, all after the completion of migration, then carry out empty machine contracting
Appearance process.
In summary, implementation through the invention, at least exist it is following the utility model has the advantages that
Virtual network resource is uniformly disposed by dynamic migration IP address according to QoS index, realizes accumulation load balancing,
And the waste of IP resource is avoided, solve the problems, such as the prior art not dynamic control IP migration.
The above is only a specific embodiment of the invention, not do limitation in any form to the present invention, all
Any simple modification, equivalent variations, combination or the modification that embodiment of above is made according to the technical essence of the invention, still
Belong to the protection scope of technical solution of the present invention.
