Abstract
The invention discloses a distribution network link disaster recovery system on a VPN. The system comprises a network distribution communication integrated access platform, a power distribution terminal, a central end VPN and an access end VPN, wherein the central end VPN is connected with the network distribution communication integrated access platform, the access end VPN is connected with a plurality of passive optical networks of a power distribution network access layer, OLT equipment is transferred to each ONU equipment through a 1:n passive optical subdivider or a multi-subdivider, and the ONU equipment is connected with the power distribution terminal to collect and control the terminal information; the access end VPN is in network connection with the central end VPN through a main link of the network and a standby link of the network; when the central end VPN detects that the main link of the network is interrupted, the main link is quickly switched to the standby link of the network and an electric power user normally accesses through the standby link of the network, so that true redundant backup of the electric power communication network is realized, and safe and stable operation of the electric power communication network is guaranteed.
Description
Technical field
The present invention relates to a kind of power distribution network network link disaster tolerance system based on VPN, belong to Distribution Network Communication technical field.
Background technology
Existing terminal communication Access Network reliability and reply disaster scarce capacity, lack effective link backup function, the words cost laying or rent private network for subsequent use is too high, and disaster tolerance safety does not end to end have very good way.And along with expanding economy and the raising of living standards of the people and the development of IT industry, the requirement of the whole society to power supply quality and power supply reliability improves day by day, is all difficult to bear even have a power failure in short-term.The network service that network equipment failure causes simultaneously is interrupted, and causes losing efficacy to distribution network monitoring, and troubleshooting and recovery difficulty strengthen, and the consequence produced at power distribution network is more and more serious.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of power distribution network network link disaster tolerance system based on VPN is provided, solve distribution network communication system in prior art and lack disaster tolerance function, power distribution network is caused to carry out data backup timely and effectively, the technical problem that distribution network monitoring lost efficacy.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: based on the power distribution network network link disaster tolerance system of VPN, comprise distribution communication synthesis access platform, distribution terminal, center-side VPN and incoming end VPN; Described center-side VPN is connected with distribution communication synthesis access platform; Described incoming end VPN connects multiple EPONs of power distribution network Access Layer, OLT device is sent to each ONU equipment by the passive optical splitter of a 1:n or what splitter, be connected with distribution terminal by ONU equipment, realize terminal information acquisition and control; Described incoming end VPN carries out network by network primary link and network backup link with center-side VPN and is connected; When center-side VPN detects network primary link breaks, fast shut-off is to network backup link, and power consumer is normally accessed by network backup link.
Described network primary link is power private network.
Described network backup link is the wired or wireless communication network of runner public-network.
Described network backup link, according to different section service type demand characteristics, carries out different section service isolation.
Adopt static state, pooled address translation and port multiplexing technique, carry out the Address Recognition of power private network and runner public-network.
Compared with prior art, the beneficial effect that the present invention reaches: the present invention is after various network equipment failure causes network interruption, can Intelligent Measurement network link status, be switched to reserve link adaptively fast and continual application service is provided, the service request of client can be continued to run, thus realize the real redundancy backup of powerline network, ensure that powerline network safely and steadily runs; Meanwhile, can ensure that power distribution network SCADA system provides normal application service to greatest extent, avoid the irresistible sudden factors such as machine room power failure, fire, earthquake to expand grid loss further; According to different section service type demand characteristics in network backup link, carry out mutually isolated to section service, ensure that safety and the confidentiality of reliability and the transmission data connecting user.
Accompanying drawing explanation
Fig. 1 is power distribution network network end-to-end link backup networking topological diagram.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, based on the power distribution network network link disaster tolerance system of VPN, distribution communication synthesis access platform, distribution terminal, center-side VPN and incoming end VPN is comprised.Distribution communication synthesis access platform is connected with distribution integrated communications network administration subsystem, distribution main station system, center-side VPN respectively.Incoming end VPN is carried out network with center-side VPN be connected by network primary link, network backup link two kinds of approach, and network primary link selects power private network, and network backup link selects the wired or wireless communication network of runner public-network.The running status of the real-time Sampling network primary link of center-side VPN, once detect that interrupting appears in network primary link, then fast shut-off is to network backup link, power consumer is normally accessed by network backup link, thus the real redundancy backup of realizing circuit communication network, ensure powerline network safe and stable operation.
Incoming end VPN connects multiple EPONs of power distribution network Access Layer, and OLT device (optical line terminal) is sent to each ONU(optical network unit by the passive optical splitter of a 1:n or what splitter), be connected with distribution terminal by ONU equipment.Power distribution station terminal can ONU equipment direct communication, also communicates with the wireless slave unit be connected on distribution terminal by the wireless master be connected in ONU equipment.
For ensureing to connect the reliability of user and transmit safety and the confidentiality of data, network backup link, according to different section service type demand characteristics, carries out different section service isolation.
The present invention, by adopting static state, pooled address translation and port multiplexing technique, carries out the Address Recognition of power private network and runner public-network.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
