Description
Technical field
The invention is related to technical field of network security, the method for more particularly to a kind of dynamic dispatching network operating system and
System.
Background technology
SDN thoughts are that the control plane for completing decision making function is moved to independent main frame or business clothes from the network equipment
It is engaged in device forming SDN controllers, referred to as network operating system (Network Operating System, NOS).Along with cloud
The development of the new technologies such as data center, this kind of frameworks for building flexible, a scalable network of SDN are changed for network field brings huge
Influence and motive force.But its own design leak existed also brings the potential safety hazard of sternness to its application simultaneously.Especially
It is the false stream injection that has occurred extensively in service process and controller is kidnapped etc. that attack makes its safety problem more prominent with threat
Go out.Including：The control framework of centralization easily turns into preferred target of attack；Open network operating system has unknown leak with after
Door；The static characteristic of current network operation system is conducive to attacker to detect and analyze key-course.And existing tradition
The Passive Defence technology of feature based matching can not resist unknown threat, therefore, to solve the above problems, must design with master
The network operating system framework of dynamic defence characteristic, the guarantee of effective security is provided for it.
The content of the invention
Instant invention overcomes in the prior art, the Passive Defence technology of feature based matching can not resist asking for unknown threat
Topic is high there is provided a kind of security performance, the method and system of the small dynamic dispatching network operating system of security threat.
The technical solution of the present invention is to provide a kind of side for the dynamic dispatching network operating system having steps of
Method, contains following steps：
Step 1：System initialization；
Step 2：Perceptron is responsible for assessing all NOS working condition, and provides assessment report；
Step 3：Assessment report is sent to scheduler by perceptron timing, updates log-on message；
Step 4：If the NOS assessment results of current Master role are normal, step 5 is performed, step 6 is otherwise performed；
Step 5：Judge whether scheduling timer is zero, if zero, then scheduler is based on scheduling strategy, according to assessment report, choosing
Select an optimal Slaver turns into new Master instead of Master, while updating log-on message；If not zero, jump to step
2；
Step 6：If monitoring finds that the NOS of Master role is abnormal, stop scheduler timing, and reset, by scheduler from
One healthy, optimal NOS of selection replaces current Master to turn into new Master in Slaver set, while more new registration
Information.
The step 1 includes：
Step 101：Dynamic mode is opened, dispatch layer reads isomery NOS log-on message from configuration file, or dynamic from isomery
NOS receives log-on message, completes registration；
Step 102：One NOS of random selection writes into registration chain as Master, and by NOS Role Informations from registration chained list
Table, for enforcement of regulations of the NOS role definitions based on OpenFlow agreements；
Step 103：Scheduler countdown is opened, and perceptron module starts；
Step 104：Bottom-layer network request of data is distributed to each through agent data and performs body, and it includes Master and all
Slavers；
Step 105：Master performs body and bottom data request is responded.
Registration is divided into automatic registration and static configuration in the step 101；Automatic registration：NOS performs body set from trend
Scheduler registers NOS identification information, and increasing or decreasing NOS can all cause the log-on message of NOS in scheduler kernel to occur phase
The change answered；Static configuration：User by hand configures NOS identification information into scheduler kernel as keeper, and these are matched somebody with somebody
Confidence breath includes port and IP address.
Scheduling strategy in the step 5 is specially：Active scheduling strategy and reactive schedule strategy；It is wherein active
Scheduling strategy, the scheduling interval of scheduler on a timeline is consistent, and no matter how bottom-layer network topology changes, and scheduler timing is certainly
Hair ground is switched over to NOS；Wherein reactive schedule strategy, perceptron module is by the safe condition of sensing network and some realities
When information, if found the abnormal situation, start scheduling strategy immediately.
A kind of system for the method for realizing dynamic dispatching network operating system is provided, containing with lower unit：
Using layer unit：The DLL that types of functionality APP is provided by key-course is programmed to underlying device；
Control layer unit：Body set is performed comprising the different N number of NOS of function equivalence structure, a class is Master NOS, had and only
There is one, be the NOS for actually managing network；One class is Slaver NOS, is alternative NOS, Slaver is called to be turned into
Master；
Dispatch layer unit：The network operating system of network and upper strata to bottom is transparent.
The scheduling layer unit contains agent data module, perceptron module, Scheduler module, wherein
Agent data module：It is the intermediate point of control plane and data plane data interaction, the network request of bottom passes through this point
It is sent to NOS and performs body set, the management control data of controller is also handed down to bottom-layer network and other dispatch layer modules through time；
Perceptron module：The safe condition of perceptron sensing network, and by information exchange to scheduler；
Scheduler module：All NOS log-on message is included, receives the information of agent data, inside there is countdown function, once meter
When device reset, scheduler according to scheduling strategy select a Slaver NOS be used as Master NOS.
Compared with prior art, the method and system of dynamic dispatching network operating system of the present invention have advantages below：Should
Framework has the function of perceiving dynamic dispatching isomery NOS, and then avoids the false flow table note initiated using NOS leaks and back door
Enter and the attack such as kidnap with NOS and threaten, also avoid attacker from being based on a successful attack and the control of sustainable utilization same leak
NOS.The security architecture of the application, dynamic, isomerism are introduced into network operating system, are dispatched NOS by dynamic realtime and are held
Row body realizes dynamic, can not only realize traditionally Internet resources and computing resource, the cooperative scheduling of storage resource, also greatly
Ground improves the security of network operating system, solves currently existing network operating system Passive Defence and there was only " the acquisition day after tomorrow
Property it is immune " passive situation.
