Description
Technical field
The present invention relates to computer software, computer network and field of cloud calculation, specifically a kind of to be based on cloud computing
The virtual network design method of route of data center.
Background technology
Calculate data center network mainly has following change relative to conventional data centers network, and cloud data center network will
Ask higher bandwidth, lower delay；Cloud data center network server node and VM scales roll up, particularly VM numbers
Amount；The management communicated between newly-increased cloud data center network VM；Two layers of interconnection between across data center website are moved with carrying virtual machine
Move etc..
For these changes that cloud data center Netowrk tape comes, cloud data center network size has been set to become very huge
Greatly, the application for carrying becomes sufficiently complex.Has there are many problem demanding prompt solutions in cloud data center network, such as maliciously attacks
Hit, virus and wooden horse cause every year the loss exceeded 100 billion；The characteristic of uncalibrated visual servo (Scale-free) allows the whole network can be
Well-designed minority accuses collapse under attacking；The appearance of the applications such as p2p was once causing each big ISP network blocking, had a strong impact on
Traditional normal access etc..In order to realize certain data isolation and Information Security, general enterprises can be created in data center
Found a capital and VLAN and be distributed VMs in the different vlans, when VM needs actively to be provided out service, it is necessary to a kind of routing network
The support of network.
Virtualization of the cloud computation data center virtual network comprising software and hardware level.The network virtualization of hardware level
Need the support of particular device, therefore increase certain hardware cost but performance may be quite a lot of.The network virtual of software level
Change relatively flexibly, the route network for meeting various demands can be built with reference to privately owned bridge vSwitch and virtual router.Therefore,
The present invention devises a kind of virtual network design method of route based on cloud computation data center, and the method can be easily in cloud
Data center network passes through software creation external Virtual router（vRouter）, user can easily configure outside after establishment
The network communication mode of virtual router vRouter, can easily be customized individual based on external Virtual router vRouter user
The network service and security strategy of property.
The content of the invention
It is an object of the invention to provide a kind of virtual network design method of the route based on cloud computation data center.
The purpose of the present invention is realized in the following manner, specifically comprising herein below；
One external Virtual router vRouter is set in route virtual network, and external Virtual router vRouter is used
In realizing the route between different segment, and various flexible network strategies are realized, including DHCP service, gateway service, DNS clothes
Business, address mapping services, flow control service, flow equalization service, VPN services and access control service, external Virtual route
The essence of device vRouter is a virtual machine, and user is by long-range flexible configuration and operates external Virtual router vRouter
To realize various flexible network demands；
External Virtual router vRouter runs on certain calculate node, the calculating that external Virtual router vRouter is located
Agent programs are run on node, Agent programs are used to receive and the network operation of feedback user is asked, and Agent processes pass through
