Description
Technical field
The present invention relates to a kind of data service processing system and method, especially a kind of data handling system based on the VPN that in the IP bearer network, is built into by first border router and second border router etc., and can handle data service processing method of data in the net without the NAT address transition based on this system.
Background technology
The science and technology develop rapidly, variation with rapid changepl. never-ending changes and improvements is also taking place in network technology.Network provides various, colourful data service for the user, and the user can connect network at any time and obtain various information.But the user is increasing to the demand of obtaining resource on the network, simultaneously, also wishes to obtain more more colourful business.Diversified data service, also making use of momentum must need various networks the service that provides is provided.
Network address translation (Network Address Translation, NAT) be meant a network internal, can random as required self-defined IP address, and do not need through application, such network can be by network address translation apparatus and other network interconnections.A network internal, each network element device carries out communication by the IP address of inside; And when inner network element need carry out communication with external the Internet, it was that legal IP address (i.e. IP address through applying for) communicates that NAT device is responsible for the IP address transition that it is inner.Therefore common data service at present can be divided into enclosed type and non-enclosed type.During the data service of user capture enclosed type, only need visit to specify the application server in the carrier network to get final product; When the non-enclosed type data service of user capture, be through specifying the network of carrier side, and then visit application server on other carrier networks.Service request from user the network of appointment carrier side of process be called Intranet; And the network of other carrier sides is called public network.So it is professional that the enclosed type data service is called in the net; But not the enclosed type data service is called the outer business of net.Therefore when the user capture net in when professional, and user terminal (User Equipment, UE) need communicate with the network internal network element and get final product, and data flow need not be passed through NAT device; And when outside the user capture net when professional, UE need communicate with the network element on the public network, and data flow need be carried out address transition through NAT device, just can set up being connected of network element on UE and the public network.
To be that example describes with user capture WAP business to the existing networking plan that is widely used below:
As shown in Figure 1, be the networking schematic diagram of prior art data service processing system, each application server 91 is positioned at and uses public ip address on the public network, and the user is divided in a plurality of user domain, uses private IP address.When the user wants to use business to initiate service request, its service request data bag palpus is through the outer professional gateway 92 of net, and promptly WAP gateway is carried out operations such as protocol conversion and insertion user ID by WAP gateway, after passing through the address transition of NAT device 93 then, the application server 91 on the visit public network.This networking plan exists following shortcoming: when carrying out address transition, run into bottleneck problem easily.Since the terminal distribution private IP address, and application server 91 is positioned on the public network, uses public ip address, and therefore, terminal access application server 91 need carry out address translation.Obviously, NAT device 93 will become the performance bottleneck of the whole network.Also can have following problem simultaneously, when new business occurring, will introduce new agreement, yet these new agreements are difficult to cross-over NAT equipment 93.It is professional as streaming media service to occur increasing big data on flows later on, and this business is used RTSP, Real-time Transport Protocol, and these agreements are difficult to cross-over NAT equipment 93.And, more and more huger when the new service flow quantitative change, the performance bottleneck problem of NAT device 93 certainly will be more outstanding.Therefore, because Business Stream must pass through address transition, so this networking plan is not suitable for the carrying out of the interior data service of net of big flow in the future.
In order to solve the above problems, a solution has been proposed in the prior art, as shown in Figure 2, networking schematic diagram for another prior art data service processing system, service server 81 is placed on the use private IP address in each user domain 8 respectively in the net among the figure, passes through net interconnection mutually in the net in the different user territory 8 between the service server 81.Yet, thisly have following problem in each user domain by the networking plan that data service is provided: because each user domain 8 is separate, can't intercommunication, therefore in the net service server 81 also must and user domain 8 correspondence one by one.Yet this certainly will cause the roamer can't visit the ownership place business, adopts this networking plan, and network can't provide the whole network unified data service for the user.In addition since in the net service server 81 must and user domain 8 corresponding one by one, if when obviously the whole network is made up of a plurality of user domain, service server 81 also must be disposed overlap more in the net.Such networking plan will make network scalability be severely limited, for the network capacity extension in future has brought great trouble.Though under this networking mode, though need not when the user uses data service through address transition, yet this networking plan can not solve the networking problem of data service veritably, more can not provide a kind of better networking plan for colourful data service in the future.
