The host of part, and be written in virtual component creation rule；Rule is finally issued to corresponding modules, is carried out
Virtual component creation, flow table entry and the creation of classification rules of entity, eventually form network group.In network, group is successfully created
Later, it needs that it is monitored and managed in real time, guarantees its efficient, stable and reasonable operation.
Fig. 7 is the method flow diagram that the wisdom contract network group of the embodiment of the present invention 2 creates, referring to Fig. 7, detailed process
It is as follows:
S1 network management personnel needs to create the group that basic security function may be implemented.Firstly, logging on to figure
Change interface, pulls three virtual functions components, be firewall, deep-packet detection system and intruding detection system respectively, then press
Three virtual functions components are connected together according to sequencing, recently enter each functional unit detected rule and entire race
Bandwidth demand 400Mb, the delay requirement 0.8s of group, and marking the group is temporary group.Network management personnel submits should
After group's creation demand, demand collection module receives demand, and standardizes each field description.
S2 template sensing module matches most suitable mirror image according to the function that three virtual components are undertaken first for it,
It is FireWall, DPI and IDS with result, due to not specific virtual component specification demands, and the overall bandwidth of group is low
In general components network interface bandwidth, time delay lower than time delay between the general components of current test feedback, so each virtual component uses
Conventional specification, i.e. CPU core number be 1, interior saves as that 512M, hard disk 1024M, 1 bandwidth of network interface are 500Mb/s, 2 bandwidth of network interface is
500Mb/s.According to the particular filter rule of particular filter rule and intruding detection system that configuration information is firewall, assembly mould
Plate matching result is that firewall component and intruding detection system component use configuration strategy virtual component template, deep-packet detection group
Part uses conventional virtual component template.Marking the group is temporary group, and group's template matching is that can destroy virtual group's mould
Relevant information was finally written in template by plate, group's life cycle using 20 days of default.
S3 template conversion module parses Template Information, is parsed by virtual component template and virtual component information
Virtual component creation rule parses classifying rules and flow table rule by configuration information and virtual group's template.
S4 calculates three according to the whole time delay bandwidth demand of virtual group and to the monitoring feedback information of whole system
The host of a virtual component.
S5 issues dependency rule to downstream module, completes group's creation.
In conclusion the method and system that a kind of wisdom contract network group of the embodiment of the present invention creates, realize from
User is abstracted the complete map that demand forwards on demand to network function actual deployment and data traffic, greatly simplifies manually-operated
Meanwhile realizing flexible, the efficient deployment of network service, and then greatly improve network resource utilization and service quality, meanwhile, this
