He communicates virtual unit.
Referring to figure 3., wherein schematically illustrating a kind of IP address applied to edge cluster provided in this embodiment
Management method is below described each step that this method includes.
Step S31 determines that the main service processes are the mesh of edge cluster distribution by the agency service process
Mark virtual ip address section.
Step S32, in receiving the edge cluster when address assignment request of newly-built virtual unit transmission, from institute
Stating in destination virtual IP address section selects a virtual ip address to distribute to the newly-built virtual unit.
In the present embodiment, multiple virtual ip address sections can be directly preset on the main service processes 12 of data center 10, then
A unassigned virtual ip address section is chosen from multiple virtual ip address sections distributes to edge cluster 21.Wherein, it distributes
Virtual ip address section to edge cluster 21 is the destination virtual IP address section.
Optionally, the multiple virtual ip address section can also be by main service processes 12 to preset virtual ip address range
Dynamic is divided and is obtained.For example, user (e.g., administrator) can configure on main service processes 12 for distributing to each edge collection
In group on fringe node virtual unit virtual ip address range, the virtual ip address range of configuration is the preset void
Quasi- IP address range.It is expected to divide obtained each virtual ip address in addition, can be configured with administrator on main service processes
The mask that section has, the mask for example can be CIDR (uncategorized inter-domain routing, Classless Inter-Domain
Routing block-size defined in).
Main service processes 12 can be on startup according to the preset virtual ip address range and the preset mask
Division obtains above-mentioned multiple virtual ip address sections.
In one example, the virtual ip address range for virtual unit distribution of administrator configurations is 10.1.0.0/
22, wherein " 22 " are mask, indicate the digit of segment number in the virtual ip address range, i.e., preceding 22 expressions segment number.Now manage
The mask that the needs of reason person's configuration divide obtained virtual ip address section is 24, i.e., finally divides obtained virtual ip address section
The digit of segment number is 24, then virtual ip address range 10.1.0.0/22 can be divided into 10.1.0.1/ by main service processes 12
24-10.1.255.0/24 totally 255 virtual ip address network segments.
Main service processes 12 can choose one from 255 above-mentioned virtual ip address network segments and distribute on startup

10.1.1.0/24 edge cluster 22 is distributed to, 10.1.2.0/24 is chosen and distributes to edge cluster 23, choose 10.1.3.0/24 points
Dispensing edge cluster 24.It is of course also possible to which choosing other virtual ip address sections distributes to edge cluster 21 to 24, as long as ensuring side
Edge cluster and virtual ip address section correspond.
The agency service process of each edge cluster can determine that main service processes are the void of cluster distribution in edge where it
Quasi- IP address section, for example, the agency service process 216 of edge cluster 21 can determine the destination virtual IP that edge cluster is assigned to
Address field is 10.1.0.0/24.
When have on any edge node in edge cluster 21 virtual unit by it is newly-built when, container 31 as escribed above is new
When building, newly-built container 31 will send address assignment request to agency service process 216, and agency service process 216 will be from determination
Destination virtual IP address section 10.1.0.0/24 in choose a virtual ip address (for example, 10.1.0.1) distribute to container 31.
Similarly, agency service process 216 can choose virtual ip address from destination virtual IP address section 10.1.0.0/24
10.1.0.2 newly-built container 32 is distributed to, chooses virtual ip address from destination virtual IP address section 10.1.0.0/24
10.1.0.3 newly-built container 33 is distributed to, chooses virtual ip address from destination virtual IP address section 10.1.0.0/24
10.1.0.4 newly-built container 34 is distributed to.
Virtual ip address is distributed unitedly to virtual unit by data center's IPAM service processes in compared to the prior art,
The mode of virtual unit distribution virtual ip address is respectively when network failure by the Agent IP AM service of fringe node, passes through Fig. 3
Shown step avoids the virtual ip address conflict that foregoing manner is likely to occur, and then avoids caused by the conflict
The problem of virtual unit can not communicate.
In the present embodiment, it is provided in bgp protocol, two nodes being connected in an autonomous system are internal each other
(Inner) bgp neighbor adheres to two connected nodes in different autonomous system external (External) bgp neighbor each other separately.And
And the BGP that each node learns routes all ebgp neighbors that will be advertised to the node.Therefore, in the present embodiment, in order to
The routing of each fringe node is got through, can be that the virtual router and each fringe node in each edge cluster are matched
Set autonomous system (AutonomousSystem, AS) mark, such as No. AS, allow virtual router establish respectively with each
The external BGP of fringe node connects, so that between the virtual router and each fringe node in edge cluster each other
Ebgp neighbor.
Such as in scene shown in Fig. 2, virtual router 215 is configured with No. AS 301, and fringe node 211 is configured with No. AS
302, fringe node 212 is configured with No. AS 303, and fringe node 213 is configured with No. AS 304, and fringe node is configured with No. AS 305.
In the case, IP address management method provided in this embodiment can also include step shown in Fig. 4, specifically describe
It is as follows.
Step S41 is selecting a virtual IP address by the agency service process from the destination virtual IP address section
After the newly-built virtual unit is distributed in address, BGP routing is generated for the virtual ip address of distribution.
Step S42 makes the virtual router to EBGP in the BGP routing configuration to the virtual router of generation
The BGP of generation described in neighbor advertisement is routed.
Wherein, the BGP routing may include the virtual ip address and its correspondence that the newly-built virtual unit is assigned to
Virtual outgoing interface, the virtual outgoing interface is usually the virtual ether of the virtual switch of the newly-built virtual unit connection
Network interface, the virtual router record have the corresponding relationship of each virtual ethernet mouth and physics Ethernet interface.Work as virtual flow-line
When device receives the data packet that purpose IP address is the virtual ip address that the newly-built virtual unit is assigned to, it can find
Corresponding BGP routing, and the data are forwarded by physics Ethernet interface corresponding to the virtual ethernet mouth of BGP routing instruction
Packet.
After the BGP routing of generation is configured to virtual router, which can be routed and be carried on road by virtual router
By being sent to all ebgp neighbors in notice message.Each fringe node, which can obtain in cluster, in such edge cluster owns
The BGP of all virtual units of fringe node is routed.In this way, the data forwarding between fringe node in edge cluster may not necessarily
Dependent on virtual router, but can directly be realized by fringe node (that is, virtual switch).
Based on this, IP address management method provided in this embodiment can also include the following steps:
It is saved in BGP routing of each fringe node to the virtual router notice received, and according to guarantor
The BGP deposited routes the forwarding data of other fringe nodes into the edge cluster.
For example, in scene shown in Fig. 2, it, can be by fringe node 212 voluntarily when container 31 sends data to container 34
It is forwarded.
So, it is possible to reduce the forwarding behavior executed by virtual router avoids virtual router from becoming edge cluster
Performance bottleneck.
Optionally, in the present embodiment, the virtual router of the gateway 11 of data center 10 and each edge cluster can also be with
Ebgp neighbor each other, in the case, the bgp route advertisement that the virtual router of each edge cluster can be learnt to
The gateway 11 of data center 10.
In practical applications, every BGP routing can become reachable or unreachable with the actual conditions of link, when a road
By state it is reachable with it is unreachable between frequently change when, claim this routing there is route flapping.Route flapping can satisfy the need
It is impacted by the forwarding performance of device, can be each edge collection in the gateway 11 of data center 10 in order to avoid such case
The corresponding virtual ip address section of group configures static routing, in this way, gateway 11 may not necessarily be from the virtual flow-line of each edge cluster
Device learns BGP routing, to avoid route flapping occur on gateway 11.
Wherein, the static routing of each edge cluster include destination virtual IP address section that the edge cluster is assigned to and
The gateway 11 is connected to the outgoing interface of the edge cluster.In this way, the gateway 11 can be according to the destination IP of data to be forwarded
Affiliated network segment determines the forwarding outlet of the data to be forwarded packet.
For example, main service processes 12 for edge cluster 21 distribute destination virtual IP address section 10.1.0.0/24 after, can
Think that edge cluster 21 creates a static routing, which includes destination virtual IP address section 10.1.0.0/24 and net
Close the mark for the outgoing interface connecting on 11 with edge cluster 21.
