Abstract
The present invention relates to a bidirectional signal transport unit capable of penetrating a firewall. Primarily, the firewall is arranged between two communication terminals of an ordinary network, a PSTN line is connected between the two communication terminals, and the PSTN line is coupled with network modules in the requiring communication terminal and the required communication terminal respectively through controlling module units on both sides. The requiring communication terminal dials a phone number of the required communication terminal, after the communication, the requiring communicating terminal sends out an IP address of the entity, a firewall PORT capable of opening communication, and related network connection information, the requested communication terminal selects connection rights so as to form a connection line of both the requiring communication terminal and the required communication terminal, so the purpose that the requiring communication terminal and the required communication terminal can penetrate the firewall to carry out bidirectional signal transmission can be realized.
Description
Skill is asked the field
" a kind of bidirectional signal transmission apparatus of penetrable fire compartment wall " of the present invention aims to provide one can be by the entity IP address that is required communication ends real-time confirmation requirement communication ends, promptly by requiring communication ends to send its entity IP address, but the fire compartment wall PORT of open communication and network of relation link information, select line power to require communication ends to carry out the device of two-way signaling transmission by being required communication ends with being required the penetrable fire compartment wall of communication ends to allow, cause the restriction of the point-to-point binding of network to solve fire compartment wall, be applicable to that especially user side main frame and server host carry out realtime graphic voice communication and numerical data transmission.
Background technology
Between the general networking transmission, server host one end of providing services on the Internet, how can utilize fire compartment wall, to prevent others to come the network of access server main frame inside, and then the turnover of data on the control network, fire compartment wall one end connects the network (via real IP) of external user end, the other end is the network of Connection Service device main frame internal-internal (virtual IP) then, the network of inside is kept apart with outside network, fire compartment wall has become to enter unique passage of internal network, therefore the data of any turnover all will be passed through fire compartment wall, determine whether and can pass through via fire compartment wall again, have therefore more added a guarantee for fail safe.
Particularly, fire compartment wall only allows some specific data to pass through, enter internal network from the outside also or internal network is transferred to extraneous data no matter be, all must could let pass through the affirmation formality of fire compartment wall, and these confirm that formality is to be finished by some complete rule and policies of setting in advance, and the firewall management personnel also should be able to visual degree of risk make flexible adjustment for the degree of security control.
Also therefore, the affirmation formality that fire compartment wall sets will mostly be that the identity that is primarily aimed at user side is confirmed, to be unfavorable for that to limit non-user side the data of network (come attacking network as utilizing a large amount of packets of information through approval, with bandwidth consumed, make server host crash because of overload) and server host is damaged; Only, so also can cause user side equally,, and will cause restriction the normal use (as the transmission of real-time image, web page monitored) of network so with the transmission of unfavorable two-way complete signal with the restriction of data upload to server host.
Summary of the invention
" a kind of bidirectional signal transmission apparatus of penetrable fire compartment wall " of the present invention promptly is provided with fire compartment wall between general networking two communication ends (require communication ends and be required communication ends), also be connected with a PSTN circuit therebetween, this PSTN circuit is also respectively by also being connected with a PSTN circuit between the control module at two ends, this PSTN circuit is also respectively by the control module unit at two ends and the mixed-media network modules mixed-media connection that requires communication ends and be required communication ends inside, in order to by the telephone number that requires communication ends to dial to be required communication ends, after conversation promptly by requiring communication ends (by the PSTN circuit) to send its entity IP address, but the fire compartment wall PORT of open communication and network of relation link information, and by being required communication ends selection line power, use to form requiring communication ends and being required the line of communication ends, carry out the purpose of two-way signaling transmission with being required the penetrable fire compartment wall of communication ends and reach the requirement communication ends.
And, can be engaged in and require communication ends image extraction, display module to be set with being required communication ends (comprising each main frame place of server host internal network), respectively the signal of being taken the photograph is sent to requiring communication ends and being required communication ends of holding in addition by the mixed-media network modules mixed-media unit with picture signal, and the picture signal that is received presented, require communication ends and be required to have between communication ends two-way realtime graphic to dial the function of putting and make.
