2) medium education (MAC, the Media Access Control) address of resource node;
3) CPU (CPU, the Central Processing Unit) ability of resource node, comprises dominant frequency, check figure etc.;
4) memory size of resource node.
Step 202: the business need of main management center cell according to user or the cloud business need of cloud management platform definition, use the resource node in virtual resource pond to create virtual network function example corresponding to business need.
This step can adopt prior art to realize, and the present invention repeats no more.
Step 203: for each virtual network function example, the resource node in this virtual network function example is divided into one or more region according to predetermined policy by main management center cell.
The specific implementation of this step includes but not limited to following implementation:
One) service that can only provide according to virtual network function example, carries out Region dividing to virtual network function example.Be specially:
First judge whether virtual network function example externally provides multinomial service, if so, the resource node that every services package contains is divided into a region, that is, number of regions is identical with service number; Otherwise, all resource nodes in this virtual network function example are all divided into a region.
Two) the resource node number in the service simultaneously provided according to virtual network function example and this example, carries out Region dividing to virtual functions example.Be specially:
When virtual network function example externally provides multinomial service, the resource node that every services package contains is divided into a region, that is, number of regions is identical with service number; When virtual network function example externally only provides one to serve, if the resource node number then in this example is greater than default field capacity reference value, then according to this field capacity reference value, this example is divided into multiple region, otherwise, all resource nodes in this virtual network function example are all divided into a region.
Or, when virtual network function example externally provides multinomial service, first the resource node that every services package contains is divided into a region in advance, namely, number of regions is identical with service number, and then check resource node number in each region, if there is the resource node number in region to be greater than default field capacity reference value, be then multiple region by this Region dividing further according to this field capacity reference value; When virtual network function example externally only provides one to serve, if the resource node number then in this example is greater than default field capacity reference value, then according to this field capacity reference value, this example is divided into multiple region, otherwise, all resource nodes in this virtual network function example are all divided into a region.
Fig. 3 gives the exemplary plot of zoning in the present invention, as shown in Figure 3,3 virtual network function examples are comprised: vNAT, vFW and virtual intrusion prevention system (vIPS in virtual network function unit, Virtual Intrusion Prevention System), wherein, vNAT only outwards provides one to serve and the resource node number comprised does not exceed predeterminable area capacity reference, then only divide a region, label is region 1; VFW externally provides two kinds of services: packet filtering and deep-packet detection (DPI, Deep PacketInspection), be then divided into two regions by vFW, label is region 2,3 respectively; VIPS only externally provides a service, but its resource node number comprised has exceeded predeterminable area capacity reference, be then divided into two regions according to this reference value, and label is region 4,5 respectively.
Step 204: main management center cell elects principle, for each region in each virtual network example elects a regional center node according to predeterminable area Centroid.
The election principle of regional center node includes but not limited to following implementation:
First, the CPU ability of all resource nodes in comparison domain, the resource node that CPU ability is the highest will be elected as regional center node.Wherein, the first dominant frequency of the CPU of more all resource nodes, what dominant frequency was the highest will be elected as regional center node, if the dominant frequency of the CPU of all resource nodes is identical, the then check figure of the CPU of more all resource nodes again, what check figure was maximum will be elected as regional center node.
When the CPU ability of resource nodes all in region is identical, then the memory size of more all resource nodes, what memory size was maximum will be elected as regional center node.
When the CPU ability of resource nodes all in region, memory size are all identical, then the MAC Address of more all resource nodes, what MAC Address was minimum or maximum will be elected as regional center node.
In actual applications, can be each region and elect two Centroids, respectively as the active and standby Centroid in region.When electing, first electing the main Centroid in region according to regional center node election principle, then in the residue node in this region, electing region for Centroid according to this principle.
Step 205: main management center cell, to the regional center node sending zone node listing notice message elected, carries the resource node list in this region in this message.
Wherein, if region has elected two regional center nodes: active and standby Centroid, then in this step, main management center cell is main Centroid sending zone node listing notice message to region, in the resource node list that this message carries, to indicate that its region is for Centroid role for region for Centroid.
Step 206: main management center cell receives and records the zone state information that each regional center node reports, and forming region is shown.

Here load is as concurrent connection number, newly-built connection speed etc.
Step 02: regional center node periodically gathers the load of each resource node in one's respective area, and the area load gathered is reported main management center cell.
Step 03: when regional center node to find in the service bearer ability that the load of one's respective area reaches one's respective area that, sending resource to main management center cell increases request message in limited time, carries the number of nodes that resource node mark and request increase in this message.
Step 04: the resource that main management center cell receiving area Centroid is sent increases request message, according to the resource node mark that message carries, corresponding idling-resource node is searched in virtual resource pond, if find, the number of nodes that the request of then carrying according to message increases, selects the idling-resource peer distribution of respective amount to this region from virtual resource pond.
If do not find corresponding resource node in virtual resource pond, then illustrate that this resource node is used up, return response message to regional center node, carry resource node in message and use up information; If find corresponding idling-resource node in virtual resource pond, but the corresponding idling-resource node in resource pool is less than the number of nodes that request increases, then main management center cell is while giving this region by the corresponding idling-resource peer distribution in resource pool, return response message to regional center node, carry in message in resource pool without enough idling-resource nodal informations.
Step 05: when regional center node finds to prescribe a time limit under the load of one's respective area is lower than the service bearer ability of one's respective area, send resource to main management center cell and reduce request message, carry the number of nodes of resource node mark and request minimizing in this request.
Step 06: the resource that main management center cell receiving area Centroid is sent reduces request message, the number of nodes that the resource node mark of carrying according to this message and request reduce, reclaims the resource node of respective amount in virtual resource pond from this region.
It should be noted that, in the embodiment of the present invention, message mutual between resource node between main management center cell and regional center node, in regional center node and region can adopt Ethernet_II form to encapsulate, except two-layer protocol head, the form of message remainder is as shown in table 1:
