Abstract
The invention discloses a power communication gateway, which is characterized by comprising a route management module type and a space communication protocol standard (SCPS)-terminal protocol (TP)/transmission control protocol (TCP) satellite link protocol transmission module type, wherein the route management module type is used for realizing route relevant protocols such as an open shortest path first interior gateway protocol (OSPF) and a label distribution protocol (LDP) and is also used for organizing a structure, maintaining route forwarding management of data and constructing a multiple protocol label switching (MPLS) message; the SCPS-TP/TCP satellite link protocol transmission module type is used for converting and sending the data; the route management module supplies route information of a Linux system; and a kernel of the Linux system provides the system route information for the SCPS-TP/TCP satellite link protocol transmission module type.
Description
Technical field
The present invention relates to the communication gate technical field, a kind of power communication gateway is provided.
Background technology
At present, in VPN (virtual private network), use the MPLS-VPN architecture more and more, and the satellite communication gateway equipment of support MPLS-VPN function, very rare, in electric power system, ground network makes up and usually also adopts the MPLS-VPN pattern to make up the ground VPN (virtual private network), yet the satellite communication system in emergency communication is based on the network configuration of pure IP mode, this pattern so that the MPLS-VPN message can not be in satellite network directly transmission, and the form that can only encapsulate by the gre tunneling message of GRE-MPLS-VPN is carried out the transmission agency of MPLS, although the correlation function of above part can be met from the ground router of costliness, but, in relevant therewith satellite communication, because the complexity of ductility and space environment during satellite transmission high, so that the bandwidth availability ratio of satellite communication link is not enough, therefore, the realization of the functions such as the control protocol conversion of more excellent space link can be used for improving the utilance of spacing wireless channel, and the equipment such as ground router seem helpless.
Summary of the invention
The object of the invention is to for existing equipment and technology Shortcomings, comprising apparatus expensive, safeguard the shortcomings such as inconvenient, there is not a kind of design of electric power gateway device to take into account ground network access and these two kinds of demands of space transmission network efficient fully, the technical scheme of related documents and materials is comparatively general, there is not the concrete actual method for designing that proposes, the invention describes the design of routing management module in the gateway function, the exchange method that it relates to correlation subsystem provides a kind of power communication gateway.
The present invention is to achieve these goals by the following technical solutions:
A kind of power communication gateway is characterized in that comprising:
The routing management module class: the routing management module class comprises the realization of the route related protocols such as OSPF, LDP, its institutional framework, the routing forwarding management of its service data and the structure of MPLS message.
SCPS-TP/TCP satellite link protocol transmission module class: be used for conversion and send data, routing management module provides the routing iinformation of linux system, and the kernel of linux system provides system routing information for this module.
In the such scheme, described routing management module comprises:
The ZSYS module: the routing iinformation that will from linux kernel, obtain as service end, and the routing table update of responsible linux kernel, and to the again distribution of route information at the different agreement subsystem;
Agreement subsystem module: agreement subsystem routing iinformation management, the response of agreement subsystem message request, linux kernel routing update management, user command Message Processing or distribution, be responsible for to the LDP protocol module configuration of OSPF/BGP Routing Protocol module and to the management of gateway database.
In the such scheme, described routing management module comprises: described ZSYS module receives the routing command message that the agreement subsystem sends, judge the routing command type of message, when being the deletion routing command, routing command message carries out the route delete function of gateway system, carry out the routing update of gateway system or add function when adding routing command, during for route again distribution command the ZSYS module again the distribution command task guard the oracle listener rear end in the agreement subsystem.
The present invention has following beneficial effect:
The integrated problem that has solved present electric power system satellite communication network existence of the present invention: the transfer problem of ground network access and satellite link communication control processor, the utilization scene of increase gateway device can be widely used in the power system network communications field.
