According to embodiments of the present invention, it is provided that a kind of powerline network system, Fig. 1 is the structure chart of this system, specifically
Including: data Layer 10, virtual sliced sheet layer 20 and key-course 30.
Concrete, data Layer 10 includes base terminal equipment 101 and data switching exchane 102, this base terminal equipment 101 with
Corresponding data switching exchane 102 is connected.Virtual sliced sheet layer 20 includes the virtual platform 201 being connected with data switching exchane, virtual
Change platform for the physical network in data Layer being divided into multiple mutually isolated logical Virtual network system 202；Key-course
30 include multiple system controller 301, are connected with logical Virtual network system respectively.
In the embodiment of the present invention, base terminal equipment is the equipment in powerline network, specifically includes power plant or change
Collecting device, monitoring device and intelligent electric meter etc. in power station.The powerline network system bag that the embodiment of the present invention provides
Contain the original base terminal equipment in power telecom network, be simultaneously introduced controller and carried out virtual at virtual sliced sheet layer
Net divides, and by virtualization, different business can be carried out simple logical separation, disposes experiment in virtual communication network
New business, and do not affect the operation of original business.Being managed collectively packet by key-course, base terminal equipment has only to
Gather or forward data, the function of base terminal equipment can be greatly simplified, and reduce the power consumption of base terminal equipment.
In a kind of possible implementation, the powerline network system that the embodiment of the present invention provides is based on SDN
(Software Defined Network, software defined network) realizes.SDN is by the control plane of powerline network and data
Forwarding plane separates, thus the controller concentrated by key-course goes to control bottom hardware, it is achieved flexible to Internet resources
Distributed in demand.In SDN, the network equipment (such as base terminal equipment) is only responsible for simple data and is forwarded, and can use
General hardware；And the operating system being originally responsible for controlling is independent network operating system by refining, it is responsible for different business
Characteristic carries out adaptation, and the communication between network operating system and traffic performance and hardware device can be real by programming
Existing.
In the embodiment of the present invention, virtual platform is Flowvisor.Concrete, FlowVisor is built upon OpenFlow
On network virtualization platform, physical network can be divided into multiple logic network, thus realize Freeware definition net by it
Network (SDN).It provides for manager and extensively defines rule to manage network rather than to come by adjusting router and switch
Management network.FlowVisor is deployed between standard OpenFlow controller and OpenFlow switch, becomes the transparent of the two
Agency.FlowVisor can be connected so that each controller controls an empty net with multiple controllers, it is ensured that each empty net mutually every
From.
Shown in Figure 2, by the network virtualization in SDN by abstract for the physical resource of network be resource in logic,
Physical network is divided into multiple virtual network in logic, between different virtual networks, carries out business isolation, to ensure
The privacy of each service-user and safety.Virtual sliced sheet is responsible for the instruction issued according to controller, flows through convergence route by all
The data of device are divided into all kinds of virtual net.Logical Virtual network system includes: EMS system, Security stability system, relay protection system
One or more in system and energy billing system；Corresponding system controller is EMS system controller, Security stability system control
Device processed, relay protection system controller and energy billing system controller.
In the embodiment of the present invention, this data switching exchane is SDN switch.Switch in SDN is responsible for sending out of affiliated area
Power plant, substation, the Various types of data collection of users and transmission.Key-course uses hierarchical design, by main controller controls
Multiple system controllers；Have employed master controller and mode that spare controller combines, beneficially load balancing and net simultaneously
The reliability of network, whole network-based control logic is totally absorbed on controller, needs adding new equipment or disposing new industry
At control plane, network is carried out corresponding configuration during business.
Data switching exchane is for obtaining the packet that base terminal equipment generates, and judges header fields and the basis of packet
Whether ground stream table mates, and when the header fields of packet matches with local stream table, carries out packet according to this locality stream table
It is forwarded to corresponding system controller.Meanwhile, when the header fields of packet does not matches that with local stream table, packet is turned
Send to the OpenFlow switch in Flowvisor；Now OpenFlow switch is used for: at packet with Flowvisor's
When data base matches, forward the packet to corresponding system controller.System controller is receiving OpenFlow exchange
After the packet that machine forwards, generate the stream list item pointing to packet, and stream list item is added to stream table, in order to subsequent match phase
The packet of cocurrent flow rule directly forwards according to stream table, otherwise by this data packet discarding.
Concrete, the communication process of this powerline network system is referring specifically to shown in Fig. 3.The basis of power telecom network is eventually
First the initial data that user produces is packaged into IP bag by end equipment (such as intelligent electric meter), and IP bag adds respective field (VLAN again
ID etc.) post package is that packet sends；After SDN switch receives packet, first carry out the head word of packet
Duan Jinhang resolves, the stream table rule then divided according to void net, is mated with stream table by this packet；Multiple (such as N when existing
Individual) stream table mates the most one by one, just sends this packet to SDN controller by escape way once the match is successful,
Determined how to process (abandon or forward) by SDN controller.If not mating existing stream table rule, packet is forwarded to
Openflow switch receiver module in Flowvisor, if the data base in coupling Flowvisor, controller could be made that
Determine add in new stream table as a new stream list item, participate in the stream rule match of next packet.
In a kind of possible implementation, shown in Figure 4, this powerline network system also includes application layer, should
Being mainly provided with user oriented input-output equipment with layer, this input-output equipment is connected with the controller in key-course.Application
Layer can issue types of applications according to work requirements with Information control centre attendant, possess extremely strong opening up
Malleability and motility；And by the feedback of controller, any content of the whole province's communication network can be obtained, be greatly improved work
Efficiency and the respond of network.
Meanwhile, key-course also includes that master controller and spare controller, master controller and spare controller are all with all of
System controller is connected.Have employed master controller and mode that spare controller combines, beneficially load balancing and network
Reliability.
The powerline network system that the embodiment of the present invention provides, power telecom network based on software defined network virtualizes
