Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides the management method of the network equipment in a kind of software defined network system, and software defined network system comprises controller and the network equipment, and controller, for managing network device communication, as shown in Figure 1, comprising:
101, controller receives the information that the network equipment reports, hardware information and the attribute information of packets of information includes network equipment; Wherein, attribute information is used for showing whether the network equipment can be defined by controller.
Wherein, SDN is a kind of new network innovation framework, and its core technology is separated network control plane and datum plane by use controller, thereby has realized the flexible control of network traffics.SDN controller is the core component of the network architecture, and the security system of the whole network that can receive to do for oneself provides the data message of the network equipment of basic service function, carries out the functions such as data communication with the network equipment.The network equipment here can be switch, server, fire compartment wall etc.
For the application characteristic of SDN scene lower network equipment, the network equipment under SDN scene can be divided into two classes, the definable network equipment and the not definable network equipment.For to the definable network equipment and can not distinguishing by define grid equipment, when controller receives the attribute information of the network equipment, controller is according to the type of the attribute information judgement network equipment.
When the network equipment is the parts that could realize based on hardware; during as hardware-related SDN safety component; for example encryption equipment must be achieved by hardware; need on the network equipment of encryption chip, carry out efficient cryptographic capabilities having; some virtual machine must be at believable credible platform module (the trusted platform module that has for another example; TPM) on the main frame of chip, move, otherwise virtual machine will lose the ability of safeguard protection.Like this, these safety components need to be defined with need, but these hardware-related safety components need to be defined as to specific parts, and at will not define.The network equipment reports SDN controller by hardware information and attribute information, so that SDN controller is determined the device type of the network equipment according to this hardware information, and determines according to attribute information whether this network equipment can be defined by controller.A specific implementation wherein, one of this use resides in an executable program HAgent in network equipment operating system (windows/linux).In HAgent program, set a upwards interface, for HAgent, the data message of the network equipment can be passed to SDN controller according to asynchronous (asynchronous) data structure of OpenFlow agreement, certainly, between controller and the network equipment, also can adopt the method for synchronization to communicate.The data communication is here not limited to OpenFlow agreement, can be also the communication of other agreement.
For the definable network equipment, the network equipment that for example fire compartment wall, intruding detection system (intrusion detection system, IDS) and anti-virus (anti-virus, AV) etc. are mainly carried out by software.That is to say, the network equipment of hardware independent can carry out software definition, and the network equipment at its place can receive the information of SDN controller data plane and control plane.
For the network equipment that can not carry out software definition, for example, certificate granting center (certificate authority, CA), auditing system, code upgrade and management etc.By dispose respectively a set of RAgent program on the network equipment, in order to represent that these network equipments can not carry out software definition.Like this, can not carry out the network equipment of software definition just by independent, be placed in an independent region, be equivalent to a SDN " isolated area ", by these network equipments, outside the definition of SDN, SDN controller can not define these network equipments.Wherein, RAgent is an executable program residing in network equipment operating system (windows/linux).
102, when the network equipment can be defined by controller, controller is according to the Data Control function of hardware information define grid equipment, and issues defined instruction to the network equipment, makes the network equipment control function according to defined instruction setting data.
For instance, when the attribute information reporting according to the network equipment when controller identifies the network equipment and can be defined by controller, when the HAgent in controller and the network equipment communicates, the hardware information that controller transmits HAgent is unified to gather with visual and is presented, and according to hardware information, determine the Data Control function of the network equipment, and issue defined instruction to the network equipment, make the network equipment control function according to defined instruction setting data.
For instance, in the hardware information of the network equipment, relate to TPM hardware, controller just can be defined as this network equipment security server, credible cloud main frame etc., and issue defined instruction to this network equipment, the network equipment, after receiving defined instruction, just knows that equipment of itself should have the Data Control function of security server or credible cloud main frame.
In addition, when the attribute information reporting according to the network equipment when controller identifies the network equipment and can be defined by controller, just can issue control command to the network equipment, to the network equipment, issue the information of control plane, make the network equipment carry out the function corresponding with control command according to control command.From the angle of the network equipment that can be defined, just can both receive the information of control plane, also can receive the information of datum plane.
Wherein, for definable secure networking device, can be divided into again hardware-related secure networking device and with the secure networking device of hardware independent.For hardware-related secure networking device, such as encryption equipment, virtual machine etc., controller can only be defined as the specific network equipment, can not at will define, but its control plane still can be separated with datum plane, but still in SDN logical architecture, just the security device network of physics can not be multiplexing with the information interaction of SDN controller.Accordingly, the secure networking device parameter of these physics will remain unchanged, with correct location and the function realization of the network equipment that ensures safety.Wherein, parameter can comprise IP(internet protocol) address, medium access control (media access control, MAC), VLAN (virtual local area network, VLAN) and subnet etc.And with the secure networking device of hardware independent, the secure networking device of mainly being carried out by software such as fire compartment wall etc., can receive the control command that controller issues and it is defined.
For instance, when the attribute information reporting according to the network equipment when controller identifies the network equipment and cannot be defined by controller, also for the network equipment of SDN " isolated area ", the RAgent disposing can be to data surface implementing monitoring or audit or statistics, obtain the information of datum plane, and the information of this network equipment datum plane is sent to SDN controller, make SDN controller and the server of " isolated area " carry out data communication.Controller just receives service data information from the network equipment that can not be defined, and this service data information is with regard to monitor data as above, or Audit data or statistics.That is to say, for the network equipment of having disposed RAgent, in the situation that can not carrying out software definition, just only carry out communicating by letter of datum plane with SDN controller, and the information that does not receive the control plane of SDN controller is carried out software definition to the network equipment.Like this, the network equipment of SDN isolated area when not carrying out software definition, the fail safe that can improve SDN system.But the software systems of installing in the network equipment still can receive the information on self-controller, specifically can realize by the simultaneous asynchronous data transmissions structure of OpenFlow, certainly, also can realize by synchronous data transmission structure.Wherein, RAgent can have two interfaces, to lower interface, can make production firm to lower interface, the information such as data statistics, Internet Transmission state are uploaded to RAgent by this, the RAgent interface that makes progress can send to SDN controller according to the asynchronous data structure of OpenFlow or synchrodata structure by data.
The embodiment of the present invention provides the management method of the network equipment in a kind of software defined network system, this software defined network system comprises controller and the network equipment, controller is for managing network device communication, by controller, receive the information that the network equipment reports, hardware information and the attribute information of packets of information includes network equipment; Wherein, attribute information is used for showing whether the network equipment can be defined by controller, when the network equipment can be defined by controller, controller is according to the Data Control function of hardware information define grid equipment, and issue defined instruction to the network equipment, make the network equipment control function according to defined instruction setting data, under SDN scene, the physical characteristic of equipment Network Based improves the serviceability of the network equipment.
