Abstract
The invention discloses a method for achieving communication between an IPV4 device and an IPV6 device. The method comprises the steps that (1), internet protocol version numbers and IP addresses of domains where a first device and a second device are located are recorded on a firewall device, and a first device virtual IP address and a second device virtual IP address are allotted for the first device and the second device respectively; (2), the first device sends a message to the second device, the format of the message is | the second device virtual IP address and the first device IP address | data |; (3), the firewall device receives the message, converters the format of the message into | the second device IP address and the first device virtual IP address | data |, and sends the message to the second device; (4), the second device receives the message, analyzes the message and sends a return message, wherein the format of the return message is | the first device virtual IP address and the second device IP address | data |; (5), the firewall device receives the return message, converts the format of the message into | the first device IP address and the second device virtual IP address | data |, and sends the message to the first device. The method for achieving the communication between the IPV4 device and the IPV6 device is easy to implement, and networking is convenient.
Description
Technical field
The present invention relates to network communications technology field, particularly a kind of method that realizes IPV4 equipment and IPV6 devices communicating.
Background technology
The network address translater of the subsidiary protocol converter of NAT-PT of the prior art (Network Address Translation-Protocol) is a kind of pure IPv6 node and the internodal intercommunication mode of IPv4, allly comprises that the conversion work of address, agreement is all completed by the network equipment.Support the gateway router of NAT-PT should have the IPv4 address pool, use when giving out a contract for a project from IPv6 to the transfer of IPv4 territory, the address in address pool is for changing source address in the IPv6 message.In addition, gateway router needs the support of DNS-ALG and these two kinds of ALGs commonly used of FTP-ALG, when the IPv6 node access IPv 4 node, plays a role.If there is no the support of DNS-ALG, can only realize being initiated by the IPv6 node with the IPv4 node between communicate by letter, otherwise not all right.If there is no the support of FTP-ALG, the main frame in the IPv4 network can not be used server downloading files or the upload file of ftp software from the IPv6 network, and vice versa.
The advantage that adopts the NAT-PT mode to carry out transition is not need to carry out IPv4, the upgrading of IPv6 node, shortcoming is the implementation method more complicated of IPv4 node visit IPv6 node, the processing expenditure that the network equipment carries out protocol conversion, address transition is larger, and general in the situation that other intercommunication modes can't be used.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is to lack the mutual method of communicating by letter between IPV4 equipment and IPV6 equipment simply and easily that realizes in prior art.
(2) technical scheme
For solving the problems of the technologies described above, the invention provides a kind of method of the IPV4 of realization equipment and IPV6 devices communicating, it is characterized in that, comprise the following steps:
S1: record respectively internet protocol version number, the IP address in the first equipment, the second territory, equipment place on firewall box, and distribute the first equipment virtual ip address, the second equipment virtual ip address for it;
S2: described the first equipment sends message to described the second equipment, and its form is:
| second equipment virtual ip address the first IP address of equipment | data |
S3: described firewall box receives described message, and is converted to:
| second IP address of equipment the first equipment virtual ip address | data |
Be sent to described the second equipment;
S4: described the second equipment receives described message, and the form of described message being resolved and sent to returned packet is as follows:
| first equipment virtual ip address the second IP address of equipment | data |
S5: described firewall box receives described returned packet, and is converted to following form:
| first IP address of equipment the second equipment virtual ip address | data |
Be sent to described the first equipment.
The internet protocol version in described the first territory, equipment place number is IPV4, and the internet protocol version in described the second territory, equipment place number is IPV6.
The internet protocol version in described the first territory, equipment place number is IPV6, and the internet protocol version in described the second territory, equipment place number is IPV4.
(3) beneficial effect
The method of IPV4 equipment provided by the invention and IPV6 communication between devices realizes simple, is convenient to networking.
Embodiment
Below the specific embodiment of the present invention is described in further detail.Following examples are used for the present invention is described, but are not used for limiting the scope of the invention.
The method of present embodiment comprises the following steps:
S1: internet protocol version number, the IP address in record the first territory, equipment place on firewall box; and distribute the first equipment virtual ip address for it; record internet protocol version number, the IP address at the second equipment place; and distribute the second equipment virtual ip address for it; if the internet protocol version at the first territory, equipment place number is IPV4; the internet protocol version in the second territory, equipment place number is IPV6; if the internet protocol version at the second territory, equipment place number is IPV6, the internet protocol version in the second territory, equipment place number is IPV4;
S2: the first equipment sends message to the second equipment, and its form is:
| second equipment virtual ip address the first IP address of equipment | data |
S3: firewall box receives described message, and is converted to:
| second IP address of equipment the first equipment virtual ip address | data | be sent to the second equipment;
S4: the second equipment receives described message, and the form of message being resolved and sent to returned packet is as follows:
| first equipment virtual ip address the second IP address of equipment | data |
S5: firewall box receives returned packet, and is converted to following form:
| first IP address of equipment the second equipment virtual ip address | data | be sent to the first equipment.
For more clearly explaining said method, now be exemplified below:
S1: the network that firewall box records PC1 is the IPV4 network, and the IP address is 1.1.1.1, and corresponding virtual IP address V6 address is 2001::1, and the network of PC2 is the IPV6 network, and the IP address is 2001::2, and corresponding virtual IP address V4 address is 1.1.1.2;
S2:PC1 sends message to PC2, and message format is:
| the former IP of 1.1.1.2 address, purpose ip address 1.1.1.1| data |
S3: firewall box receives described message and is converted to:
| the former IP of 2001::2 address, purpose IP address 2001::1| data | be sent to PC2;
S4:PC2 receives described message, and returned packet is resolved and sent to described message:
| the former IP of 2001::1 address, purpose IP address 2001::2| data |
S5: firewall box receives described returned packet, and according to corresponding relation, returned packet is converted to:
