In addition, the computational resource that on each physical server that SDN controller also receives this Cloud Server monitoring that Cloud Server sends, each virtual machine takies, be directed to each physical server, the ratio of the computational resource sum take virtual machines all on this physical server and the computational resource total value of this physical server is defined as the computational resource utilization rate of this physical server.
Wherein, in Cloud Server Real-Time Monitoring SDN, on physical server, each virtual machine takies the situation of the computational resource of physical server.
It should be noted that, SDN controller can prestore the bandwidth in the VXLAN tunnel between each physical server and gateway device, SDN controller can also prestore the computational resource total value of each physical server, or obtains the computational resource total value of each physical server from described Cloud Server.
The physical server that network resource utilization is not less than default Internet resources warning value by step 102:SDN controller is defined as alarm physical server, or physical server computational resource utilization rate being not less than default computational resource warning value is defined as alarm physical server.
Step 103:SDN controller determination alarm physical server needs the virtual machine moved.
In this step, network resource utilization due to alarm physical server is not less than Internet resources warning value, or computational resource utilization rate is not less than computational resource warning value, in order to avoid there is network congestion or computational resource deficiency, need the traffic transport of virtual machine on corresponding minimizing alarm physical server, the network resource utilization of alarm physical server is made to be less than Internet resources warning value, or reduce the computational resource taken of virtual machine on alarm physical server, the computational resource utilization rate of alarm physical server is made to be less than computational resource warning value, therefore can by the virtual machine (vm) migration on alarm physical server be realized this goal to the physical server of Internet resources and computational resource relative free.

Step 104:SDN controller determination object physical server.
In this step, the method of SDN controller determination object physical server is: SDN controller is less than the physical server of Internet resources warning value from network resource utilization selects a physical server met the following conditions to be defined as object physical server: object physical server to superpose the traffic forwarding speed on virtual machine that needs the move VXLAN tunnel between alarm physical server and gateway device with the traffic forwarding speed in the VXLAN tunnel between gateway device after, and the ratio of the VXLAN tunnel bandwidth between object physical server and gateway device is less than default Internet resources warning value, and, after the computational resource that the computational resource sum superposition that on object physical server, all virtual machines take needs the virtual machine of migration to take on alarm physical server, default computational resource warning value is less than with the ratio of the computational resource total value of object physical server.
Preferably, physical server minimum for network resource utilization in the physical server meeting above-mentioned condition can be defined as object physical server by SDN controller.
Preferably, physical server minimum for computational resource utilization rate in the physical server meeting above-mentioned condition can be defined as object physical server by SDN controller.
Step 105:SDN controller sends virtual machine (vm) migration notice message to Cloud Server, makes Cloud Server need the virtual machine (vm) migration of migration on object physical server.
In this step, SDN controller sends virtual machine (vm) migration notice message to Cloud Server, Cloud Server is made to need the virtual machine (vm) migration of migration on object physical server, thus the network resource loads alleviated on alarm physical server and computational resource load, make the network resource utilization of alarm physical server be less than Internet resources warning value, computational resource utilization rate is less than computational resource warning value.
That expresses for making the object, technical solutions and advantages of the present invention clearly understands, below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.
Be described in detail below in conjunction with the moving method of specific embodiment to above-mentioned virtual machine.
The present embodiment adopts the SDN structure chart shown in Fig. 2, as shown in Figure 2, there are physical server 1, physical server 2 in SDN, (the present embodiment is only described there are three physical servers in SDN physical server 3, in practical application, the number of units of physical server is not construed as limiting), physical server 1 is provided with virtual machine VM1, VM2, VM3, physical server 2 is provided with virtual machine VM4, and physical server 3 is provided with virtual machine VM4, VM5.Wherein, physical server 1 and gateway are by VXLAN tunnel 1 converting flow, and physical server 2 and gateway device are by VXLAN tunnel 2 converting flow, and physical server 3 and gateway device are by VXLAN tunnel 3 converting flow.For convenience of process, the present embodiment is only using cpu resource and memory source as computational resource; SDN controller is preset with Internet resources warning value, CPU warning value and internal storage warning value, suppose in the present embodiment that Internet resources warning value, CPU warning value and internal storage warning value are 90%, in practical application, each resource alarm value is arranged according to actual needs.
Fig. 3 is the flow chart of the present embodiment, as shown in Figure 3, comprises the following steps:
Step 301:SDN controller determines each physical server network resource utilization, CPU usage and memory usage.
In this step, SDN controller receives the VXLAN tunnel 1 of this gateway device monitoring, the traffic forwarding speed in VXLAN tunnel 2 and VXLAN tunnel 3 that gateway device sends, and receive VM1, VM2, VM3 traffic forwarding speed respectively on VXLAN tunnel 1 of its monitoring that physical server 1 sends, VM5, VM6 traffic forwarding speed respectively on VXLAN tunnel 3 of its monitoring that the traffic forwarding speed of VM4 of its monitoring that physical server 2 sends on VXLAN tunnel 2 and physical server 3 send.
Then the SDN controller traffic forwarding speed in VXLAN tunnel 1 of being monitored by gateway device and the ratio of VXLAN tunnel 1 bandwidth are defined as the network resource utilization of physical server 1, the traffic forwarding speed in VXLAN tunnel 2 of monitor gateway device and the ratio of VXLAN tunnel 2 bandwidth are defined as the network resource utilization of physical server 2, and the traffic forwarding speed in VXLAN tunnel 3 of monitor gateway device and the ratio of VXLAN tunnel 3 bandwidth are defined as the network resource utilization of physical server 3;
Or, the ratio of traffic forwarding speed sum respectively on VXLAN tunnel 1 of VM1, VM2, VM3 and VXLAN tunnel 1 bandwidth is defined as the network resource utilization of physical server 1 by SDN controller, the ratio of the traffic forwarding speed of VM4 on VXLAN tunnel 2 and VXLAN tunnel 2 bandwidth is defined as the network resource utilization of physical server 2, the ratio of traffic forwarding speed sum respectively on VXLAN tunnel 3 of VM5, VM6 and VXLAN tunnel 3 bandwidth is defined as the network resource utilization of physical server 3.
In addition, the cpu resource that VM1 ~ VM6 that SDN controller also receives this Cloud Server monitoring that Cloud Server sends takies respectively and memory source, be directed to physical server 1, the ratio of cpu resource sum VM1, VM2, VM3 taken and the cpu resource total value of physical server 1 is defined as the cpu resource utilization rate of physical server 1, and the ratio of memory source sum VM1, VM2, VM3 taken and the memory source total value of physical server 1 is defined as the memory source utilization rate of physical server 1; Be directed to physical server 2, the ratio of the cpu resource total value of the cpu resource taken by VM4 and physical server 2 is defined as the cpu resource utilization rate of physical server 2, and the ratio of the memory source total value of the memory source taken by VM4 and physical server 2 is defined as the memory source utilization rate of physical server 2; Be directed to physical server 3, the ratio of cpu resource sum VM5, VM6 taken and the cpu resource total value of physical server 3 is defined as the cpu resource utilization rate of physical server 3, and the ratio of memory source sum VM5, VM6 taken and the memory source total value of physical server 3 is defined as the memory source utilization rate of physical server 3.
Suppose that each physical server network resource utilization, cpu resource utilization rate and memory source utilization rate that in this step, SDN controller is determined are as shown in table 1:
Table 1
Step 302:SDN controller determination alarm physical server.
Particularly, physical server network resource utilization being not less than default Internet resources warning value is defined as alarm physical server, or physical server cpu resource utilization rate being not less than default cpu resource warning value is defined as alarm physical server, or physical server memory source utilization rate being not less than default memory source warning value is defined as alarm physical server.
Known based on table 1, the network resource utilization of physical server 1 is 95%, is greater than Internet resources warning value 90%, and therefore, physical server 1 is defined as alarm physical server by SDN controller.
Step 303:SDN controller determination physical server 1 needs the virtual machine moved.
In this step, the traffic forwarding speed on each comfortable VXLAN tunnel 1 of VM1, VM2, VM3 that SDN controller sends according to physical server 1, supposes that traffic forwarding speed is followed successively by VM2, VM1, VM3 from high to low.Then after the traffic forwarding speed that SDN controller judges on VXLAN tunnel 1 deducts the traffic forwarding speed of VM2 on VXLAN tunnel 1, the Internet resources warning value of physical server 1 whether is less than with the ratio of VXLAN tunnel bandwidth, if, then VM2 is defined as the virtual machine needing migration, otherwise after continuing to consider that physical server removes VM2 and VM1, whether network resource utilization is less than Internet resources warning value, with aforementioned, method judges that the method for VM2 is identical, repeat no more.
Because physical server 1 is that network resource utilization is not less than Internet resources warning value, therefore the network resource utilization only considering physical server 1 when needing the virtual machine of migration is determined, if what alarm physical server triggered is computational resource warning value, after needing to consider to remove virtual machine when then judging to need the virtual machine of migration, whether the computational resource utilization rate of alarm physical server is less than computational resource warning value, if alarm physical server triggers Internet resources warning value and computational resource warning value simultaneously, after then judging the virtual machine needing when needing the virtual machine of migration simultaneously to consider to remove needs migration, whether the network resource utilization of alarm physical server and computational resource utilization rate have all been less than warning value.
The object physical server that VM2 moves determined by step 304:SDN controller.
In this step, because physical server 1 is that network resource utilization is not less than Internet resources warning value, therefore first consider VM2 to be moved on the minimum physical server of network resource utilization, as shown in Table 1, the network resource utilization of physical server 3 is minimum, first judge whether VM2 can move on physical server 3, the following condition of this demand fulfillment: after the traffic forwarding speed of traffic forwarding speed superposition VM2 on VXLAN tunnel 1 in VXLAN tunnel 3, default Internet resources warning value is less than with the ratio of VXLAN tunnel 3 bandwidth, and, virtual machine VM5 on physical server 3, after the cpu resource that the cpu resource sum superposition VM2 that VM6 takies takies on physical server 1, default cpu resource warning value is less than with the ratio of the cpu resource total value of physical server 3, virtual machine VM5 on physical server 3, after the memory source that the memory source sum superposition VM2 that VM6 takies takies on physical server 1, default memory source warning value is less than with the ratio of the memory source total value of physical server 3.
If physical server 3 meets above condition, then physical server 3 is defined as object physical server by SDN controller.Otherwise SDN controller judges whether the physical server 2 that network resource utilization second is few can be defined as object physical server, and process no longer describes in detail in the same way.
Suppose the object physical server that in this step, physical server 3 moves for VM2.
Step 305:SDN controller sends virtual machine (vm) migration notice message to Cloud Server, and VM2 is moved on physical server 3 by Cloud Server.
In the present embodiment, the physical server 1 that network resource utilization is greater than default Internet resources warning value by SDN controller is defined as alarm physical server, then by Cloud Server, the VM2 on physical server 1 is moved on physical server 3, after ensureing VM2 migration, the network resource utilization of physical server 1 and computational resource utilization rate are all less than default warning value, the network resource utilization of physical server 3 and computational resource utilization rate and are also all less than default warning value.The method considers the coordinated allocation of computational resource and Internet resources, when ensureing physical server computational resource abundance, can not bring the problem such as access delay or interruption because Internet resources become new bottleneck.
