Fig. 1 show the Autonomic Migration Framework method for managing system flow chart of the Virtual NE equipment based on SDN, and this method can be with
Include the following steps: in a step 101, Virtual NE equipment accesses the virtual switch of sourcesink host；In a step 102, source
The virtual switch of host reports Virtual NE equipment access events to SDN controller；In step 103, SDN controller root
Corresponding configuration rule is issued according to the interface type and/or connection relationship of the Virtual NE equipment of access sourcesink host；In step
In 104, Virtual NE equipment transportation to target host machine；In step 105, the virtual switch on sourcesink host reports virtually
Network element device removes event to SDN controller；In step 106, SDN controller provides interim configuration rule to sourcesink host
Virtual switch to guarantee network-in-dialing, and specifically can by get around remove Virtual NE equipment network path to guarantee net
Network connection；In step 107, SDN controller clears up sourcesink master according to the type and/or connection relationship that remove Virtual NE equipment
Configuration rule of the machine virtual switch to the network element device；In step 108, the virtual switch of target host machine reports virtually
Network element device access events notify SDN controller to have the immigration of Virtual NE equipment to SDN controller；In step 109, SDN control
Device processed issues configuration rule according to the interface type and/or connection relationship for the Virtual NE equipment for moving into target host machine；In step
In rapid 110, SDN controller removes interim rules and recovery configuring on the virtual switch of sourcesink host.The present embodiment then side
Step 104 is overweighted to step 110.
Interface type and/or company of the SDN controller meeting according to the Virtual NE equipment for being related to removal event in the present embodiment
The relationship of connecing issues corresponding configuration rule, but configuration rule is issued according to this is not limited only to, can also according to network element device its
Its parameter carries out regular configuration.
Fig. 2 to Fig. 7 is by taking the system comprising three Virtual NE equipment VNF1, VNF2 and VNF3 as an example for the present embodiment
System and management method are described in detail.Fig. 2 is the logic of connection relationship between Virtual NE equipment before removal event occurs
Schematic diagram；Fig. 3 is that system physical schematic diagram before removal event occurs；Fig. 4 is to connect between Virtual NE equipment in transition process
The logical schematic of relationship；Fig. 5 is system physical schematic diagram in transition process；Fig. 6 be migration after the completion of Virtual NE equipment it
Between connection relationship logical schematic；Fig. 7 is system physical schematic diagram after the completion of migration.The virtual switch of target host machine in figure
Machine is with the mark of virtual switch 1, and the virtual switch of sourcesink host is with the mark of virtual switch 2.
As shown in Figure 2 and Figure 3, before removal event occurring, VNF2 connects the virtual switch of sourcesink host with VNF3.
The virtual switch of VNF1 linking objective host.And VNF1 is separately connected virtual friendship by VNF2 connection VNF3, SDN controller
It changes planes 1 and virtual switch 2.At this point, configuration rule includes that the rule of VNF2 connection VNF3 and VNF1 connect on virtual switch 2
Connect the rule of VNF2.Configuration rule includes the rule of VNF1 connection VNF2 on virtual switch 1.
As shown in Figure 4, Figure 5, VNF2 only remains VNF3 connection sourcesink during from sourcesink host migration to target host machine
The virtual switch of host.The virtual switch of VNF1 then linking objective host.And there are connection relationships with VNF3 by VNF1.
SDN controller is separately connected virtual switch 1 and virtual switch 2.At this point, configuration rule only includes on virtual switch 2
The rule of VNF1 connection VNF3.Configuration rule includes the rule of VNF1 connection VNF3 on virtual switch 1.
As shown in Figure 6, Figure 7, after VNF2 smoothly moves to target host machine from sourcesink host, only VNF3 connection sourcesink master
The virtual switch of machine.The virtual switch of VNF1 and VNF1 linking objective host.And VNF1 is by VNF2 connection VNF3,
SDN controller is separately connected virtual switch 1 and virtual switch 2.At this point, configuration rule can include on virtual switch 2
The rule of VNF2 connection VNF3.Configuration rule includes the rule and VNF2 connection VNF3 of VNF1 connection VNF2 on virtual switch 1
Rule.
By upper analysis it is found that the virtual switch of sourcesink host can be adjusted after SDN controller receives the migration event of VNF2
Machine configuration rule is to keep the network-in-dialing of transition process, and by the rule of VNF1 connection VNF2 from matching on virtual switch 2
It sets in rule and removes, and issue the rule of VNF2 connection VNF3 in virtual switch 1.
The present embodiment also proposes a kind of Autonomic Migration Framework system of Virtual NE equipment based on SDN, using software defined network
Network provides network-in-dialing function, which includes virtual switch, SDN controller and Virtual NE equipment；SDN controller is used
After receiving the Virtual NE equipment removal event that sourcesink host virtual switch reports, adjust virtual switch configuration rule with
The network-in-dialing of transition process is kept, and clears up the configuration rule for removing Virtual NE equipment from the virtual switch of sourcesink host
Then, and the configuration rule for moving into Virtual NE equipment is issued in the virtual switch of target host machine.SDN controller further can
The connection status of dynamic monitoring Virtual NE equipment, avoids the archive of redundancy link relationship.
The SDN controller of the present embodiment will record the connection relationship of whole network element devices, and control virtual switch in turn
Realize the management to Virtual NE equipment connecting relation.SDN controller receives the virtual net that sourcesink host virtual switch reports
After element device removal event, not only the virtual switch configuration rule of adjustable sourcesink host is to keep the network of transition process
Connection, can also adjust the configuration rule of sourcesink host and target host machine simultaneously to keep the network-in-dialing of transition process.
Virtual switch of the SDN controller based on openflow protocol integrated test system sourcesink host and target host machine.Specifically,
Virtualization network element device is connected to virtual switch, and SDN controller is based on openflow protocol integrated test system virtual switch, virtualization
Network element device is connected with each other by SDN based on Openflow protocol realization.
The system that this implementation proposes further includes interactive window, for configuring for network management personnel to SDN controller
Management, input control instruction, SDN controller update Virtual NE equipment connecting relation after obtaining the instruction that user inputs.Meanwhile
Network management personnel obtains the Virtual NE equipment global state of real-time full also by interactive window.
Virtual NE equipment can be firewall, router, load balancer, intruding detection system or intrusion prevention system
System.And the connection type of different Virtual NE equipment be it is different, such as: firewall largely use route pattern and thoroughly
Bright bridge mode, load balancing largely use reverse proxy, and intrusion prevention system uses mirror port or drainage.
