Abstract
The invention relates to the technical field of computer networks, provides a telecommunication internal network remote access method and solves a problem of accessing a telecommunication internal network through a public network. According to the telecommunication internal network remote access method, double network cards are configured in a device of an isolation internal network and a device of a telecommunication private network under an internal development environment of a company, and developers can remotely cross a network to access a telecommunication server through an internal network device, so that company staffs can debug the vast majority of functions of an IPTV service without leaving the company. According to the telecommunication internal network remote access method, the research and development efficiency is improved, and the research and development costs are reduced.
Description
Technical field
The invention belongs to computer technology and network technology field, in particular to a kind of method of long-range access telecommunications Intranet.
Background technology
IPTV refers to the information network audiovisual material service with quality services guarantee by carrying out for television terminal based on the IPTV dedicated network of fixed communication network. IPTV by Set Top Box except providing the TV basic services such as live telecast, program request, carousel, time shift, playback to user, also integrating the television value-added services such as home shopping, tele-medicine, video education, guide book, ticket booking reservation, Electronic mail, stock exchange, IPTV service is the important component part of Network TV Station of China new medium.
In recent years, each network operator constantly expands IPTV service, but the IPTV network overwhelming majority of IPTV service is all private network, cannot be accessed by public the Internet, this makes each terminal producer have to arrange the research staff of oneself to debug to telecommunications Intranet, the efficiency of research staff's research and development is lower, also can spend a large amount of human costs and time cost simultaneously.
Summary of the invention
[technical problem to be solved]
It is an object of the invention to provide a kind of method of long-range access telecommunications Intranet, to solve by public network the access problem of telecommunications Intranet.
[technical scheme]
The present invention is achieved by the following technical solutions.
The present invention relates to a kind of method of long-range access telecommunications Intranet, comprise step:
Configure the first network interface card and the 2nd network interface card on the first device, configuring the 3rd network interface card and the 4th network interface card on the second device, described first network interface card connects company's end public network, and described 2nd network interface card connects company's end Intranet, described 3rd network interface card connects telecommunications end public network, and described 4th network interface card connects telecommunications end Intranet;
Company's end Intranet sends the data packet that telecommunications private network conducts interviews, and the first network interface card of the first equipment receives this data packet and it encapsulated again, is then sent to public network by the 2nd network interface card;
2nd equipment receives the data packet of the 2nd network interface card transmission of the first equipment by the 3rd network interface card, the data packet received is carried out Xie Bao, by the 4th network interface card, the data after Xie Bao are forwarded to telecommunications private network.
As one preferred embodiment, described packet encapsulation specifically comprises: raw data packets to be sent is regarded as data data, adds the head information comprising the specific IP address of the other side.
As another preferred embodiment, described data packet Xie Bao specifically comprises: to the data from the specific IP of the other side received, removes head information, is reduced to raw data packets.
As another preferred embodiment, the encapsulation of described data packet is conciliate bag process and is all carried out in the transport layer of TCP/IP.
[useful effect]
The technical scheme that the present invention proposes has following useful effect:
The present invention is by the Equipments Setting double netcard of equipment and telecommunications private network that will isolate Intranet in intra-company's development environment, developer can by Intranet apparatus remote across a network access telecommunication server, the function of the overwhelming majority that just can debug IPTV service so that manufacturer personnel " stay indoors ", improve efficiency of research and development, reduce R&D costs.
Accompanying drawing explanation
Data forwarding process schematic diagram in the method for the long-range access telecommunications Intranet that Fig. 1 provides for embodiments of the invention one.
The data encapsulation that Fig. 2 provides for embodiments of the invention one and Xie Bao illustrate figure.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, carry out clear, complete description by the specific embodiment of the present invention below.
Embodiment one
Embodiment one provides a kind of method of long-range access telecommunications Intranet, and the method comprising the steps of:
(1) company's end equipment, telecommunications end equipment prepare
Company development environment Intranet IP section 192.168.1.XXX, public network IP section 10.3.46.XXX.
Telecommunications end Intranet environment IP section 192.168.2.XXX, public network IP section 10.3.46.XXX.
Company end PC configures the first network interface card and the 2nd network interface card, telecommunications end PC configures the 3rd network interface card and the 4th network interface card, first network interface card connects company's end public network and obtains IP:10.3.46.1,2nd network interface card connects company's end Intranet and obtains IP:192.168.1.1,3rd network interface card connects telecommunications end public network and obtains IP:10.3.46.2, and the 4th network interface card connects telecommunications end Intranet and obtains IP:192.168.2.1. Company end PC installs double netcard data forwarding procedures (such as PortTunnel), it is achieved the data between the first network interface card and the 2nd network interface card forward. Telecommunications end PC installs double netcard data forwarding procedures (such as PortTunnel), it is achieved the data between the 3rd network interface card and the 4th network interface card forward. Specifically, the data forwarding process in the method for the long-range access telecommunications Intranet that embodiment one provides is as shown in Figure 1.
(2) company's end Intranet sends the data packet that telecommunications private network conducts interviews, and first network interface card of company end PC receives this data packet and it encapsulated again, is then sent to public network by the 2nd network interface card. Packet encapsulation specifically comprises: raw data packets to be sent is regarded as data data, add the head information such as etherhead, IPhead, the Tcphead taking telecommunications end public network IP (10.3.46.2) as sending destination location, it is packaged as a new TCP bag, being sent on telecommunications end public network 10.3.46.2, packet encapsulation and solution packet procedures are as shown in Figure 2.
(3) data packet that telecommunications end PC is sent by the 2nd network interface card of the 3rd network interface card acquiring company end PC, carries out Xie Bao to the data packet received, by the 4th network interface card, the data after Xie Bao is forwarded to telecommunications private network. Data packet Xie Bao specifically comprises: to the data from the specific IP of the other side received, removes the head information such as etherhead, iphead, Tcphead, is reduced to raw data packets, as shown in Figure 2.
Needing to illustrate, in the present embodiment, the encapsulation of data packet is conciliate bag process and is all carried out in the transport layer of TCP/IP.
