Description
Technical field
The present invention relates to the IP technical field, relate in particular to a kind of Operational Visit method, Apparatus and system.
Background technology
Along with global Internet Protocol version 4 (IPv4; Internet Protocol Version 4) address exhausts and professional requirement to terminal " always online "; The deployment of Internet Protocol version 6 (IPv6, Internet Protocol Version 6) technology will become inevitable.In order to realize the deployment that IPv6 is technological and to seamlessly transit, need set the introducing strategy and the application scenarios of IPv6 technology.In order progressively to introduce the notion of IPv6 network, the construction of IPv6 network and IPv4/IPv6 dual stack network will become the first step that the IPv6 technology is disposed.The IPv6 transitional technology mainly comprises two stacks, three kinds in translation and tunnel, and every kind of technology is divided into several scenes again, has therefore produced a variety of solutions, but up to today, large-scale deployment is also still limited.In order to promote and guide the development of IPv6 technology, multiple application will progressively realize support and the processing to IPv6.Along with the popularization and the maturation of IPv6 technology, can predicting in the near future, IPv6 uses the main flow presentation mode that will become Internet service.About the evolution of IPv6 technology, the Internet engineering duty group (IETF) has also been carried out a series of practicable theoretical predictions, points out that the evolution of IPv6 mainly is divided into three phases among the standard rfc5211 of working group according to the issue of ietf standard tissue:
Stage one: IPv6 evolution initial stage; Most service provides also based on IPv4 in the network; In order to realize the transition to IPv6, various IPv6 transitional technologies (comprising tunnel, translation and double-stack technology) will progressively be implemented in network, and increase the correlative flow of IPv6 in the network gradually.
Stage two: IPv4 and IPv6 technology co-existence stage, this stage occurs in the period of being expected at 2010 to 2011.In this stage, Internet service provider will be simultaneously provide the business of IPv4 and IPv6 respectively to the user, and user's concrete condition more judges and selects desired type of service.In this stage, IPv6 disposes scale will be increased gradually, and have the abundant equally service resources with IPv4.
In the stage three, in the later stage of IPv6 technology evolution, this stage is expected at 2012 and occurs later on.Business will be main with IPv6 in the network, and the scope that the IPv4 business provides will progressively be dwindled, and the IPv6 network also becomes the main networking technology form in the Internet.The IPv4 network range faces atrophy.The transition to IPv6 will be accomplished in the internet.
Can see that from above analysis along with the development of business, the professional presentation mode of IPv6 will become the main flow mode that following the Internet provides gradually, this makes that also professional requirements for access also increases with it in the IPv6 network.
In this case, though the IPv4 network will progressively disappear, the complete obiteration of IPv4 technology and IPv4 network still need be experienced a very long time.The long tail can scientifically be predicted the whole process of IPv4 network future development, even if the IPv6 prevailing IPv6 evolution later stage of technology, the IPv4 network also will exist in relevant wide scope.Cause this phenomenon that various reasons is arranged, for example exist the used equipment that to support IPv6, individual operators to consider that the IPv6 upgrading drops into and fail to support IPv6 application etc. in the network.Under this network application scene, how to make that host application visits the IPv6 business through the IPv4 network in the IPv4 network and be called problem demanding prompt solution.
In order to address this problem, also exist many methods to realize visiting the IPv6 business in the field at present through the IPv4 network.Such as, the Teredo technology is exactly a kind of technology that is used to realize visiting through the IPv4 network IPv6 business.Particularly, the Teredo technology is the transitional technology that Microsoft's function is released, and on Windows operating system, has carried out integrated at present.Its main principle is to utilize tunnel style to realize the intercommunication of IPv4 main frame and IPv6 through on main frame, setting up logic interfacing.Based on the configuration of Teredo on main frame, the host logic interface can obtain the IPv6 address of intercommunication.When host application in the IPv4 network is initiated the Operational Visit request to IPv6, data communication is carried out in the IPv6 address that directly utilizes logic interfacing, set up IPv6in UDP in IPv4 tunnel and realize that the IPv6 data are in the IPv4 transmission through network.In data transmission procedure, the decapsulation that Teredo Relay accomplishes data will be set, and realize data forwarding professional in the IPv6 territory.Similar Teredo technology also exists some open source softwares to realize the visit of IPv4 to IPv6 at present in the Internet, like gogo6 etc., has all adopted and has set up tunnel style and realize the intercommunication of IPv4 to IPv6.
In practical application, above-mentioned prior art is proved to be and has disadvantage:
Teredo techniques make use IPv6in IPv4 accomplishes in the tunnel and is arranged in IPv4 network main frame and the exchange of IPv6 data in server, and its whole communication essence is that the IPv6 application exchanges through the IPv4 tunnel with between the IPv6 server on the completion IPv4 main frame.This scheme can overcome the gateway interpreting equipment and realize being responsible for, disposes problems such as poor expandability.If but IPv6 is not supported in the application on the main frame; When just its application system Socket API that source code called only supports IPv4 (the following main frame of IPv4 of will only supporting abbreviates the IPv4 main frame as); Because the IPv4 main frame can't be known the IPv6 address of IPv6 server; Therefore the IPv4 main frame is to generate and to send packet according to the IPv6 address of host logic interface assignment, thereby also just can't realize the tunnel encapsulation of IPv6in IPv4.Similarly, under above-mentioned situation, the such tunnel scheme of gogo6 also can't be realized the business intercommunication of IPv4 to IPv6.
