Description
Technical field
The present invention relates to a kind of power test method, it is based on after the transformation for concretely relating to legacy network architectural framework
The network electric power method of testing of SDN automation equipments.
Background technology
With the complication of application, people's information requirement is continuously increased, and available data center is occurred in that much itself can not
The problem of solution, it is necessary to which available data center is optimized or rebuild, especially data center network will be rebuild.So
Background under, expedited the emergence of many data center network new technologies.Following data center network includes three-major-items：SDN、
The virtual private data center of Overlay stateless network, vDC.The core concept of this three-major-items is all around software, automation
Management, grand designs, people is freed from cumbersome configuration, data center network can be disposed more extensive,
This is exactly required for large-scale corporation.
SDN is well known earliest, i.e. software defined network.Core concept is by network function and service processing function
Decoupled with network device hardware, become the function of abstract, then control by external controller these abstract objects.It is logical
The frameworks close coupling framework of legacy network is split as applying, controlled, is forwarded three layers of separation are crossed, network will no longer turn into restriction
The bottleneck that business is reached the standard grade with cloud efficiency, but while data transfer task is completed, calculating after also becoming and virtualize,
Storage resource is the same, as a kind of resource that can flexibly allocate.In data center, network technology is one closed the most
Point, this causes the bottleneck that network develops as data center for a long time, and the investment of network portion also occupies data center
A big chunk of gross investment.SDN arrival seeks to break the closure of this network, allows network to move towards opening.
SDN includes controller and openflow two large divisions, and controller is a software, and whole network equipment can be entered
Row management and control, management include issuing forwarding-table item, and control includes being monitored all-network equipment running status.
Openflow is the language of intercommunication between controller and the network equipment, and controller is carried out by Openflow to all-network equipment
Forwarding-table item is issued, equipment control.For a long time, people be intended to by data center can become it is a kind of it is more flexible, convenient, by
The resource that demand takes, can just free " software " from " hardware " platform by disposing SDN, realize the hope of people
Hope.
But for the general a set of SDN of multiple computer rooms in the case of, need to be respectively configured SDN in multiple computer rooms and bar be set
Part, the efficiency manually set is very low, and can not carry out unmanned automatic setting on duty.It is disposable in the prior art to set
Equipment of the good configuration file due to configuration in different computer rooms is different, also can not be general.
The content of the invention
The invention solves the problems that configuration of the SDN controllers in different computer rooms, while setting an equipment to cause SDN to set
The download that journey can be configured according to computer room and practical operation situation is optimized.
It should be noted that the present invention is used in power test work, kiowatt is due to safety reasons, each region
Network is not attached in outer net, but is connected by Intranet, and physical isolation is also provided with the Intranet of different zones, because
This many content directly can not need human configuration by network configuration.And can be led if the unified download using mechanization
Cause single SDN strategies can not adapt to the different actual conditions of each computer room.
For solution described problem, the network electric power method of testing of the invention based on SDN automation equipments, it uses portable

It is preferred that, the insulation antistatic casing is cylinder.
It is preferred that, described portable SDN deployment terminal is linked into after SDN switch, the detection of equipment test adaptor
The equipment that SDN switch is connected, and matched with the allocation plan preloaded in memory, find in Primary Hard Drive after matching scheme
SDN configuration files are written in SDN switch, and datum plane is formed in SDN switch, and data are instructed and plan according to key-course
Slightly forwarded the packet in datum plane, while being deleted after the control ability of original network equipment is extracted, by independent SDN
Controller is controlled, and these control abilities include determining the forward-path of each Business Stream in network, while being provided to application layer
The interface of corresponding function controlling, finally by application, the interface for calling key-course to provide realizes Topology Discovery, flow work
Journey and flow isolation features carry out network electric power test job.The extraction and deletion of the control ability of original network equipment are not
Only to the deletion of original control software, and port unnecessary in the work of SDN controllers is closed, while also deleting
The backup resetted.But the daily record of work of control program will be backed up on will recording disk on weekdays before.
It is preferred that, SDN controllers pass through SDN according to current network Link State and the control of the traffic matrix of current network
The forwarding strategy of the network traffic of router, reaches the load balancing of network., can be in work if network load reaches the upper limit
Make log recording hard disk remarks prompting message, it is necessary to additionally increase hardware device.
It is preferred that, portable SDN deployment terminal can change forwarding strategy in real time when being linked into SDN switch, but work as
Portable SDN deployment terminal departs from after SDN switch, using only the forwarding strategy of the SDN selections finally used.It thus is avoided that
SDN deployment is beyond control.
It is preferred that, portable SDN deployment terminal is linked into after SDN switch, and daily record of work recording disk is started working simultaneously
Whole operation process is recorded, is disconnected until portable SDN disposes terminal and SDN switch.
As a result of methods described, terminal progress SDN controls are disposed by connecting portable SDN in segregate computer room
The configuration of device, the state of net where the configuration of SDN controllers is collected, and according to the road of the different QoS requirements of business acquisition business
By strategy, the quality of flow transmission is improved；Net state where another aspect SDN controllers can be integrated is using different network electricity
Power Test Strategy, reduces regulation and control granularity, and net where improving carries out the flexibility of network electric power test.
