Abstract
The present invention provides a kind of IPv4 network and the mixing network method of IPv6 network, comprises the following steps: S1, be packaged message to be sent so that it is include IPv4 heading and IPv6 heading；S2, according to current network type, the association message head of described message to be sent is carried out route querying, and described message to be sent is forwarded.The present invention, by encapsulating two IP heads to message to be sent, when message passes through mixed net, looks only for the IP head being correlated with, and ignores IP head incoherent with current network, it is achieved that the non-maintaining purpose exempting to change IP address.
Description
Technical field
The present invention relates to computer network field, particularly to a kind of IPv4 network and IPv6 network
Mixing network method and system.
Background technology
IPv6 is the IP of future generation for substituting existing IPv4 that Internet Engineering group (IETF) designs
Agreement, the problem solving IPv4 address exhaustion.Due to the application of IPv6 be one incremental
Process, IPv4 network and IPv6 network can exist simultaneously and needs are in communication with each other in for a long time,
But, IPv4 node host is to differ with IPv6 node host due to the design structure of IP layer protocol
, so can not directly communicate, then when message must be through the network of IPv4 and the net of IPv6
During network, message directly cannot be forwarded.
Based on this, prior art needs to be improved really.
Summary of the invention
For the deficiencies in the prior art, the present invention provides the mixed net of a kind of IPv4 network and IPv6 network
Method and system so that message can pass through IPv4 network and the IPv6 network of mixed net, and by directly
Forward.
For realizing object above, the present invention is achieved by the following technical programs:
The present invention provides a kind of IPv4 network and the mixing network method of IPv6 network, comprises the following steps:
S1, message to be sent is packaged so that it is include IPv4 heading and IPv6 heading；
S2, according to current network type, the association message head of described message to be sent is carried out road
By searching, and described message to be sent is forwarded.
Preferably, described step S2 farther includes:
S21, judge the type of current network, if described current network is IPv4 network, then perform
Step S22, if described current network is IPv6 network, then performs step S23；
S22, IPv4 heading to described message to be sent carry out route querying, and treat described
Send message and make IPv4 forwarding；
S23, IPv6 heading to described message to be sent carry out route querying, and treat described
Send message and make IPv6 forwarding.
The present invention also provides for the mixed net system of a kind of IPv4 network and IPv6 network, includes:
Encapsulation unit, for being packaged message to be sent so that it is include IPv4 heading
With IPv6 heading；
Route querying unit, for according to current network type, the phase to described message to be sent
Close heading and carry out route querying, and described message to be sent is forwarded.
Preferably, described route querying unit farther includes:
Judgment sub-unit, is used for judging that current network type is IPv4 network or IPv6 network；
IPv4 route querying subelement, for when described current network is IPv4 network, to described
The IPv4 heading of message to be sent carries out route querying, and described message to be sent is made IPv4
Forward；
IPv6 route querying subelement, for when described current network is IPv6 network, to described
The IPv6 heading of message to be sent carries out route querying, and described message to be sent is made IPv6
Forward.
The present invention provides a kind of IPv4 network and the mixing network method of IPv6 network and system, by being treated
Send message two IP heads of encapsulation, when message passes through mixed net, look only for the IP head being correlated with, and neglect
Slightly incoherent with current network IP head, it is achieved that the non-maintaining purpose exempting to change IP address, and this
Invention is when realizing, and old networking mode need not change, and only need to increase new IPv6 in old network
Equipment can realize.
Accompanying drawing explanation
Fig. 1 is the flow chart of one embodiment of the invention；
Fig. 2 is the system block diagram of one embodiment of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is made the most in detail
Describe.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
The present invention provides a kind of IPv4 network and the mixing network method of IPv6 network, comprises the following steps:
S1, message to be sent is packaged so that it is include IPv4 heading and IPv6 heading；
S2, according to current network type, the association message head of described message to be sent is carried out road
By searching, and described message to be sent is forwarded.
As it is shown in figure 1, the specific embodiment of the invention is as follows:
A, message to be sent is packaged so that it is include IPv4 heading and IPv6 heading；
B, judge the type of current network, if described current network is IPv4 network, then perform step
Rapid C, if described current network is IPv6 network, then performs step D；
C, IPv4 heading to described message to be sent carry out route querying, and by described pending
Literary composition of delivering newspaper is made IPv4 and is forwarded；
D, IPv6 heading to described message to be sent carry out route querying, and by described pending
Literary composition of delivering newspaper is made IPv6 and is forwarded.
The present invention also provides for the mixed net system of a kind of IPv4 network and IPv6 network, includes:
Encapsulation unit, for being packaged message to be sent so that it is include IPv4 heading
With IPv6 heading；
Route querying unit, for according to current network type, the phase to described message to be sent
Close heading and carry out route querying, and described message to be sent is forwarded.
Preferably, described route querying unit farther includes:
Judgment sub-unit, is used for judging that current network type is IPv4 network or IPv6 network；
IPv4 route querying subelement, for when described current network is IPv4 network, to described
The IPv4 heading of message to be sent carries out route querying, and described message to be sent is made IPv4
Forward；
IPv6 route querying subelement, for when described current network is IPv6 network, to described
The IPv6 heading of message to be sent carries out route querying, and described message to be sent is made IPv6
Forwarding, its corresponding block diagram is as shown in Figure 2.
The present invention provides a kind of IPv4 network and the mixing network method of IPv6 network and system, by being treated
Send message two IP heads of encapsulation, when message passes through mixed net, look only for the IP head being correlated with, and neglect
Slightly incoherent with current network IP head, it is achieved that the non-maintaining purpose exempting to change IP address, and this
Invention is when realizing, and old networking mode need not change, and only need to increase new IPv6 in old network
Equipment can realize.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, relevant
The those of ordinary skill of technical field, without departing from the spirit and scope of the present invention,
Can also make a variety of changes and modification, the technical scheme of the most all equivalents falls within the present invention
Category, the scope of patent protection of the present invention should be defined by the claims.
