A very long transitional period is also needed between IPv4 to IPv6, within this very long transitional period, between realization IPv4 and IPv6
The network equipment of intercommunication will play the part of a very important role, the network topology structure signal of intercommunication between IPv4 and IPv6
Figure is as shown in Figure 1.
Realize the gateway (hereinafter referred to as Interworking gateway) of IPv4 and IPv6 intercommunications using high speed network processor and high property at present
Energy universal computing platform composition hardware platform, by disposing one or more transition protocols on a computer platform, realizes IPv4
Intercommunication between network and IPv6 networks.The transition protocol used at present mainly has NAT-PT (Network Address
Translation-Protocol, the network address translater of subsidiary protocol converter), NAT64, IVI etc., because of realization mechanism not
Together, different transition protocols are good and bad for each tool in the application.
As previously mentioned, the resource at present on network is most or using IPv4 addresses, in order to realize that IPv6 hosts can
The resource in IPv4 networks is accessed, need to pay the utmost attention to conversion and inverse conversion of the IPv6 addresses to IPv4 addresses.Institute at present

A data packet carries out conversion calculating (stateless conversion), shows the flow diagram statelessly converted in Fig. 2, same in figure
When show the schematic diagram of related data packets form in a specific example, another kind is to need to preserve IPv4 hosts and IPv6
Host correspondence mappings table carries out the conversion (stateful conversion) of data packet further according to mapping table, stateful conversion is shown in Fig. 3
A flow diagram, the schematic diagram of the related data packets form in a specific example is also shown in figure.Statelessly
Translation-protocol supports N:The conversion of N, stateful translation-protocol support N：1 (multiple IPv6 addresses correspond to an IPv4 address) turns
It changes.
Stateless conversion does not need to consumption memory and preserves mapping table, and do not need to table look-up, be relatively suitable for flow compared with
High network service accesses (such as Online Video viewing, HTTP (Hyper Text Transfer Protocol, Hyper text transfer
Agreement) download, FTP (one of File Transfer Protocol, the agreement in ICP/IP protocol group) is downloaded etc.), still, by
1 is accomplished that in stateless translation-protocol:1 access stencil, though so it realizes the intercommunication of IPv4 and IPv6, IPv6 nets
Every host in network is required for a public network IP v4 address, the actually depletion rate there is no reduction IPv4 addresses, not
IPv4 addresses can be efficiently solved and lack dilute problem.
Stateful translation-protocol can by NAT (Network Address Translation, network address translation) agreement
To realize N:1 access mode can not need to independent IPv4 addresses for IPv6 host terminals, converted and assisted using this kind
View can effectively reduce the consumption of IPv4 host addresses, and network service that is relatively low compared with suitable for flow and being not required to long connection accesses
(such as web page browsing, mail transmission/reception), but need to establish the correspondence of IPv6 internal address and IPv4 public network addresses, it needs
Consume the mapping table for the rete mirabile host that the memory source of Interworking gateway accesses current hosts and its to be preserved to initiate, transfer efficiency
Will be less than stateless translation-protocol, when IPv6 hosts and its to IPv4 access resource increase when, mapping table can increase rapidly, and can lead
Its transfer efficiency is caused to substantially reduce.

Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, with reference to the accompanying drawings and embodiments, to this
Invention is described in further detail.It should be appreciated that the specific embodiments described herein are only used to explain the present invention,
Do not limit protection scope of the present invention.
Fig. 4 is the flow diagram of the IPv4-IPv6 transition protocol dispatching methods in one embodiment of the invention, the implementation
Example is illustrated for being applied to Interworking gateway.As shown in figure 4, the method in the present embodiment includes step：
Step S401：Analyze the type of service of Operational Visit request that the IPv6 hosts received are sent；
Step S402：The mapping relations corresponding to the IPv6 hosts are obtained, the mapping relations are included for the IPv6
The IPv4 addresses of host assignment and the correspondence of IPv6 addresses,
Step S403：Judge whether the address style of the IPv4 addresses matches with the type of service, if matching,
S404 is entered step, if mismatching, enters step S405；
Step S404：The Operational Visit is asked using translation-protocol corresponding with the address style of the IPv4 addresses
It is handled；
Step S405：For the IPv4 addresses of address style that the IPv6 host assignments and the type of service match,
And the mapping relations of the newly assigned IPv4 addresses and IPv6 addresses are established, and using the address class with newly assigned IPv4 addresses
The corresponding translation-protocol of type handles Operational Visit request.
It is the industry asked the Operational Visit that IPv6 hosts are sent according to the scheme of embodiment present invention as described above
Service type is analyzed, and the difference based on type of service, the address to be matched using the business distribution type asked with Operational Visit
The IPv4 addresses of type, and Operational Visit request is handled using translation-protocol corresponding with the address style, in this feelings
Under condition, used translation-protocol is that the type of service asked with Operational Visit is matched, so as to ensure user's visit
In the case of asking normally, the transfer efficiency of Interworking gateway and resource application are effectively improved, and IPv6 networks can be effectively reduced
The demand of middle IPv4 addresses.
Before the Operational Visit request that IPv6 hosts are sent is received, Interworking gateway can in advance for IPv6 host assignments
Location ensures being smoothed out for communication process accordingly.Accordingly, as shown in figure 4, before step S401, step can also be included：
Step S4001：Receive the IPv6 application IP addresses request that the IPv6 hosts are sent；
Step S4002：For the IPv6 addresses of IPv6 host assignments IPv4 private net addresses mapping, and build in the mapping table
Found the IPv4 private net addresses and the mapping relations of IPv6 addresses.
As noted previously, as stateless conversion is accomplished that 1:1 access stencil is relatively suitable for the higher network industry of flow
Business, and stateful translation-protocol can realize N:1 access mode can effectively reduce the consumption of IPv4 host addresses, relatively suitable
Relatively low and be not required to the network service of long connection and access for flow, accordingly, in a specific example, above-mentioned matched rule can
To do following setting：
When the type of service is high flow capacity business, the address style of matched IPv4 addresses is IPv4 public network addresses,
Translation-protocol corresponding with IPv4 public network addresses is stateless translation-protocol；
When the type of service is low discharge business, the address style of matched IPv4 addresses is IPv4 private net addresses,
Translation-protocol corresponding with IPv4 private net addresses is stateful translation-protocol.
And the type of service of Operational Visit request, it can be determined based on various possible modes.Due to different network industries
Business is generally transmitted using the different network transmission protocols, to meet the demand of different network services, therefore, in the present invention
A specific example in, can based on Operational Visit ask the corresponding communication protocol of data packet come determine the Operational Visit please
The type of service asked.On the other hand, the corresponding communication protocol of data packet is embodied generally by the port numbers in data packet
, therefore, the port numbers in another specific example of the present invention or in the data packet based on Operational Visit request
Determine the type of service of Operational Visit request.
For example, the port numbers of HTTP (Hyper Text Transfer Protocol, hypertext transfer protocol) are 80,
The port numbers of RTP (Real-time Transport Protocol, real-time transport protocol) are 5005, SMTP (Simple Mail
Transfer Protocol, Simple Mail Transfer protocol) port numbers be 25 etc..What http protocol generally corresponded to is that website is visited
It asks and video traffic, corresponding smtp protocol is mail service.Therefore, if testing and analyzing out the data packet in Operational Visit request
In port numbers for 25, please if it is detected that analyzing Operational Visit it may be considered that corresponding type of service is low discharge business
Port numbers in the data packet asked are 80, it may be considered that corresponding type of service is high flow capacity business.
In addition, it is contemplated that for an IPv6 host, IPv4 can be unfavorable for by distributing two IPv4 addresses simultaneously for it
Therefore effective use of address, is described after the address style of above-mentioned judgement IPv4 addresses is mismatched with the type of service
Before the IPv4 addresses of address style that IPv6 host assignments match with the type of service, can also first it delete in mapping table
Corresponding to the mapping relations of the IPv6 hosts.
And IPv4 public network addresses are limited, if the constantly IPv6 host assignment IPv4 public networks for progress high flow capacity business
Address is bound to cause the relatively low utilization rate of IPv4 public network addresses.It therefore, can be in the specific example of the present invention
After for the IPv6 host assignments IPv4 public network address predetermined amount of time, the IPv4 public network addresses are withdrawn, are deleted in mapping table
The IPv4 public network addresses and the mapping relations of the IPv6 addresses, and be the IPv6 host assignments IPv4 private net addresses, it is reflecting
The mapping relations of the IPv4 private net addresses and IPv6 addresses are established in firing table.
Wherein, above-mentioned predetermined amount of time can be based on actual needs and be set.In a specific example, this is predetermined
Period can be set as fixed value, such as 1 hour, 2 hours.
In another specific example, which can also be dynamically determined, in the case, for each of distribution
IPv4 public network addresses, corresponding predetermined amount of time may be different.Such as according to still unappropriated IPv4 public network addresses
Number determine the predetermined amount of time, if the number of still unappropriated IPv4 public network addresses is also more, can determine one
A relatively long predetermined amount of time if the number of still unappropriated IPv4 public network addresses is less, can determine a phase
To shorter predetermined amount of time.
Based on IPv4-IPv6 transition protocols dispatching method as described above, Fig. 5 is shown in a specific example
The flow diagram of IPv4-IPv6 transition protocol dispatching methods in the example is illustrated with reference to a detailed process.
As shown in figure 5, in this example, IPv6 hosts can be sent out before normal service interaction is carried out to Interworking gateway
Send the application request of application IPv6 addresses.
Interworking gateway can receive the application request of the application IPv6 addresses of IPv6 hosts transmission, and be the IPv6 hosts point
The IPv6 addresses with the mapping of IPv4 private net addresses with one.
In subsequent communication process, when Interworking gateway receives the Operational Visit request of IPv6 hosts transmission, analysis should
The type of service of Operational Visit request, it is high flow capacity business or low discharge business to judge it, specifically analyzes type of service
Mode may be used mode as described above and carry out.
If high flow capacity business, then the IPv4 public network addresses whether having corresponding to the IPv6 addresses are inquired in mapping table
Mapping relations determine whether IPv4 addresses corresponding with the IPv6 hosts are IPv4 public network addresses.
If there is IPv4 public network addresses and the mapping relations of IPv6 addresses, then directly using stateless translation-protocol to described
Operational Visit request is handled.
If without IPv4 public network address and the mapping relations of IPv6 addresses, i.e., IPv4 address corresponding with the IPv6 hosts
It is not IPv4 public network addresses, then whether have IPv4 public network address can distribute, if not having, wait for until there is IPv4 public affairs if inquiring
Net address can distribute, if so, then carrying the IPv6 addresses of IPv4 public network addresses mapping for the IPv6 host assignments, and in mapping table
It is middle to establish the IPv4 public network addresses distributed, the mapping relations of IPv6 addresses, it can also include this simultaneously in the mapping relations
The information of IPv6 host domain names.Then, you can Operational Visit request is handled using stateless translation-protocol.Its
In, while the IPv6 hosts mapped for the IPv6 host assignments with IPv4 public network addresses or before, can also first delete
The existing IPv4 private net addresses for being directed to the IPv6 hosts and the mapping relations of IPv6 addresses.
If low discharge business, then inquiring the IPv4 addresses of the IPv6 addresses in mapping table corresponding to the IPv6 hosts is
No is IPv4 public network addresses.
If IPv4 public network addresses, then the IPv4 public network addresses are recycled, and delete the IPv4 public network addresses in mapping table
It is again one IPv4 private net address of the IPv6 host assignments, and establish in the mapping table with the mapping relations of IPv6 addresses
The mapping relations of IPv4 private net addresses and IPv6 addresses, and using stateful translation-protocol to Operational Visit request at
Reason.
If not IPv4 public network addresses, then can directly using stateful translation-protocol the Operational Visit is asked into
Row processing.
Wherein, stateful translation-protocol here can be NAT-PT (Network Address Translator-
Protocol Translator, the network address translation of subsidiary protocol converter) agreement or NAT64 (Network Address
64,64 editions network address translations of Translator) agreement, it can be that (IV-VI, 46 turn mutually IVI that stateless translation-protocol, which is,
Change) agreement.
