Abstract
The utility model discloses a network isolation data exchanger, which comprises an intranet server, an extranet server, a graphic card and an image acquisition card. The intranet server is connected with the extranet server by a video line; the graphic card and the image acquisition card are respectively arranged on the intranet server and the image acquisition card; the graphic card of the intranet server and the image acquisition card of an extranet are in the communication connection; and the image acquisition card of the intranet server and the graphic card of an extranet are in the communication connection. The network isolation data exchanger has the advantages that the data security of a special network can be effectively ensured by arranging the graphic card and the image acquisition card on the intranet server and the extranet server and by converting data into video data, so as to realize the data exchange of the intranet and the extranet.
Description
Technical field
The utility model belongs to data processing field, particularly a kind of Network Isolation data exchange unit.
Background technology
Continuous development along with China's informatization, construction and application integration level to information system software also improve day by day, based on the various infrastructure services of public network network with use and also become increasingly abundant, how these services are offered the present situation that system applies in the dedicated network is subject to dedicated network and the isolation of outer net network physical.Some ad hoc networks particularly, two networks of intranet and extranet for safe and secret reason from the network level physical isolation, but two networks all have equipment in same machine room, distance is very near, because network is obstructed, outer online main frame can not be provided by the service that provides on the intranet host, and interior online main frame can not be provided by the service that provides on the outer net main frame.
The utility model content
The purpose of this utility model is the deficiencies in the prior art, proposes a kind of Network Isolation data exchange unit that can guarantee that special intranet and extranet network security can make intranet and extranet interconnect again.
The Network Isolation data exchange unit comprises interior network server, outer network server, display card, image pick-up card, and described interior network server is connected by video line with outer network server; On network server and the outer network server display card and image pick-up card are installed respectively in described; The display card of network server and the image pick-up card of outer net establish a communications link in described, and the image pick-up card of interior network server and the display card of outer net establish a communications link.
On network server and the outer network server outgoing telecommunication proxy module and service agent module are arranged all in described.
Described outgoing telecommunication proxy module is mainly finished three functions, is respectively: dateout is encoded; Service agent module in the management present networks receives the service agent module link information, and the agency service proxy module is visited the service that moves in another network; After receiving the service request of another network, is connected with real service program in the present networks, visit is served really, and to another network echo message.
Described service agent module, major function is: the configuration file of reader network server is determined configuration information, link to each other with we's outgoing telecommunication proxy module in view of the above, the link information of registration and the other side's service agent module, and start serve port; The solicited message of customer in the present networks is mail to our communication agent module, the echo message of communication agent module is forwarded to the customer.
Network Isolation data exchange unit described in the utility model, by interior network server and outside display card and image pick-up card all are installed on the network server, and, can effectively guarantee the data security of dedicated network by data being converted to the mode of video data, realize interconnecting of intranet and extranet.

Embodiment
As shown in Figure 1, the Network Isolation data exchange unit comprises interior network server, outer network server, display card, image pick-up card, and described interior network server is connected by video line with outer network server; On network server and the outer network server display card and image pick-up card are installed respectively in described; The display card of network server and the image pick-up card of outer net establish a communications link in described, and the image pick-up card of interior network server and the display card of outer net establish a communications link.
On network server and the outer network server outgoing telecommunication proxy module and service agent module are arranged all in described.
Described outgoing telecommunication proxy module is mainly finished three functions, is respectively: dateout is encoded; Service agent module in the management present networks receives the service agent module link information, and the agency service proxy module is visited the service that moves in another network; After receiving the other side's service request, is connected with real service program in the present networks, visit is served really, and to another network echo message.
Described service agent module, major function is: determines configuration information by reading configuration file, links to each other with we's outgoing telecommunication proxy module in view of the above, the link information of registration and the other side's service agent module, and start serve port; The solicited message of customer in the present networks is mail to our communication agent module, the echo message of communication agent module is forwarded to the customer.
As shown in Figure 2, outer net has certain service request to Intranet, this request transfers data to the outgoing telecommunication proxy module by service agent module, the outgoing telecommunication proxy module is encoded to data, data behind the coding are transferred to the outgoing telecommunication proxy module of Intranet by video line, and the outgoing telecommunication proxy module of Intranet is by the real service program of service agent module visit Intranet.
Usually in computer information technology was handled, byte was a kind of unit of measurement that is used for meter store capacity and transmission capacity, and the form of byte stream is carried out during data in Network Transmission is mutual.Owing to do not allow under the situation on physical connection road in Intranet and outer net, the utility model is to adopt video flowing to replace the bridge joint of byte stream as message transmission, therefore need adopt new new coded system to data.
A function of the outgoing telecommunication proxy module in the Network Isolation data exchange unit described in the utility model is encodes to data, described coded system is to adopt " pixel color value representation method ", " pixel color value representation method " is to utilize each pixel can be by R, G, three value representations of B, the span of each value is 0-255, and this value can represent to expand ASCI I sign indicating number, what use pixel color value representation packed byte conversion expression is that pixel capacity takies, and no longer needs pixel is carried out two system encoding and decoding.
Claims (2)
1. the Network Isolation data exchange unit comprises interior network server, outer network server, display card, image pick-up card, and described interior network server is connected by video line with outer network server; On network server and the outer network server display card and image pick-up card are installed respectively in described; The display card of network server and the image pick-up card of outer net establish a communications link in described, and the image pick-up card of interior network server and the display card of outer net establish a communications link.
2. Network Isolation data exchange unit as claimed in claim 1 all has outgoing telecommunication proxy module and service agent module on network server and the outer network server in it is characterized in that.
