Abstract
The method that the invention discloses communication of exchanging visits between a kind of IPV6 isolated island, by being respectively provided with fire wall between two IPV6 and IPV4 networks in advance, the IP address all recording each IPV6 equipment in two fire walls and the virtual ip address distributed for it, after the first fire wall and the second fire wall receive message, the IP address of message is changed, it is achieved thereby that between IPV6 equipment and pass through the exchanging visit communication of IPV4 network.The method of the present invention is easily achieved, and economize on resources cost.
Description
Technical field
The present invention relates to network communication technology field, particularly to the method for communication of exchanging visits between a kind of IPV6 isolated island.
Background technology
Between Traditional IP V6 isolated island, access generally uses the form in tunnel to shield and passes through heterogeneous networks, makes two IPV6 isolated islands
Can not the existence of heterogeneous networks in the middle of perception.But shortcoming is to need that message carries out increase IP head to process, and now message can become
Greatly, the forwarding of message and treatment effeciency can be made to reduce, this method does not change message size, is directly replaced by IP head, reaches tunnel
Purpose, and do not increase message size.
Summary of the invention
(1) to solve the technical problem that
The technical problem to be solved in the present invention is to lack in prior art to realize IPV6 equipment simply and easily and pass through IPV4
Public network and the method for another one IPV6 equipment intercommunication.
(2) technical scheme
For solving above-mentioned technical problem, the method that the invention provides communication of exchanging visits between a kind of IPV6 isolated island, its feature
It is, comprises the following steps:
S1: between an IPV6 equipment and IPV4 equipment, set respectively between described IPV4 equipment and the 2nd IPV6 equipment
Put the first firewall box and the second firewall box；
S2: record a described IPV6 equipment, described on described first firewall box, described second firewall box
The IP address of the 2nd IPV6 equipment is also respectively allocated the first virtual IP address V4 for a described IPV6 equipment, described 2nd IPV6 equipment
Address, the second virtual IP address V4 address;
S3: the one IPV6 equipment sends message:
| the 2nd IPV6 IP address of equipment the oneth IPV6 IP address of equipment | data |；
Described message is converted to following form by the S4: the first firewall box:
| second the first virtual IP address V4 address, virtual IP address V4 address | data |
S5: described message passes IPV4 network, and described message is converted to following form by described second firewall box:
| the 2nd IPV6 IP address of equipment the oneth IPV6 IP address of equipment | data |
Send to described 2nd IPV6 equipment；
S6: the two IPV6 equipment receives described message, and message resolves and send returned packet:
| IPV6 IP address of equipment the 2nd IPV6 IP address of equipment | data |
S7: the second firewall box is converted to following form to described returned packet:
| first the second virtual IP address V4 address, virtual IP address V4 address | data |
S8: described returned packet pass described IPV4 network, described first firewall box described message is converted to as
Lower form:
| IPV6 IP address of equipment the 2nd IPV6 IP address of equipment | data |
And send to a described IPV6 equipment.
Described step S1 also includes being the first firewall box and the second fire wall is connected with a described IPV6 equipment
One end that one end and described IPV4 equipment connect is respectively allocated IP address.
(3) beneficial effect
The inventive method is by being respectively provided with fire wall in advance, at two fire walls between two IPV6 and IPV4 networks
In all record each IPV6 equipment IP address and for its distribution virtual ip address, when the first fire wall and the second fire wall
After receiving message, the IP address of message is changed, it is achieved thereby that between IPV6 equipment and pass through the mutual of IPV4 network
Visit communication.The method of the present invention is easily achieved, and economize on resources cost.
Detailed description of the invention
Below the detailed description of the invention of the present invention is described in further detail.Following example are used for the present invention is described,
But it is not limited to the scope of the present invention.
The method of present embodiment comprises the following steps:
S1: be between an IPV6 equipment and IPV4 equipment, set respectively between described IPV4 equipment and the 2nd IPV6 equipment
Put the first firewall box and the second firewall box；
S2: all record on the first firewall box, the second firewall box an IPV6 equipment IP address and for its
Distribution the first virtual IP address V4 address and the IP address of the 2nd IPV6 equipment and for its distribute the second virtual IP address V4 address;
S3: the one IPV6 equipment sends message:
| the 2nd IPV6 IP address of equipment the oneth IPV6 IP address of equipment | data |；
Described message is converted to following form by the S4: the first firewall box:
| second the first virtual IP address V4 address, virtual IP address V4 address | data |
S5: described message passes IPV4 network, and described message is converted to following form by described second firewall box:
| the 2nd IPV6 IP address of equipment the oneth IPV6 IP address of equipment | data | send to described 2nd IPV6 equipment；
S6: the two IPV6 equipment receives described message, and message resolves and send returned packet:
| IPV6 IP address of equipment the 2nd IPV6 IP address of equipment | data |
S7: the second firewall box is converted to following form to described returned packet:
| first the second virtual IP address V4 address, virtual IP address V4 address | data |
S8: described returned packet pass described IPV4 network, described first firewall box described message is converted to as
Lower form:
| IPV6 IP address of equipment the 2nd IPV6 IP address of equipment | data | also send to a described IPV6 equipment.
Further, described step S1 also includes being the first firewall box and the second fire wall sets with a described IPV6
One end that standby one end connected and described IPV4 equipment connect is respectively allocated IP address.
The inventive method is by being respectively provided with fire wall in advance, at two fire walls between two IPV6 and IPV4 networks
In all record each IPV6 equipment IP address and for its distribution virtual ip address, when the first fire wall and the second fire wall
After receiving message, the IP address of message is changed, it is achieved thereby that between IPV6 equipment and pass through the mutual of IPV4 network
Visit communication.The method of the present invention is easily achieved, and economize on resources cost.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, common about technical field
Technical staff, without departing from the spirit and scope of the present invention, it is also possible to make a variety of changes and modification, therefore own
