Problems solved by technology
However, this method cannot meet the dynamic needs of end users, and lacks flexibility and effectiveness. For example, user terminals need to connect to IPTV network service providers to obtain IPTV services at a certain moment, and need to connect to Internet network services at another moment provider for web browsing or OTT (Internet Television) services
[0006] IP tunnel mode: the user terminal obtains its own IP address, specifies the IP address of the access node of the virtual network system, and establishes an IP tunnel between itself and the access node. However, in this mode, the IP tunnel traverses the last mile And access to the network system, waste of network resources, and low data transmission efficiency

Embodiment Construction
[0024] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] in such as figure 1 In the network topology diagram of the access network system shown, the access network system 20 will be responsible for providing network connections between user terminals 11, 12, 13, several virtual network systems 30, 31 and the Internet 32, wherein:
[0026] The user terminal 11 belongs to the user of the virtual network system 31, and it has agreed with the network operator on the network bandwidth and service quality; the user terminal 12 belongs to the user of the virtual network system 31 and the Internet 32, and it operates The security is agreed between the providers; the user terminal 13 belongs to the user (VLAN) of the virtual network system 30 .
[0027] The access network system 20 includes several network access devices 211, 212, a control server 220 and so on. The network access equipment can...

The invention provides a method for a control user terminal in an access network system to access a virtual network system. The access network system comprises a control server and a plurality of network access facilities connected with the control server. Network connectionism is created in the control server, and is used for accessing the user terminal to the corresponding virtual network system in a pre-defined mode on the network access facilities. Then the control server sends the network connectionism corresponding to the user terminal to the network access facilities, and the network access facilities configure the user terminal to a network link of the virtual network system according to the network connectionism. In an access authentication device, when the user terminal carries out access authentication, the control server configures the network connectionism to the network access facilities in an access authentication protocol mode.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for configuring a user terminal to a designated virtual network system in an access network system. Background technique [0002] The Internet has developed from a "best-effort" data service at the beginning to an all-encompassing application of the Internet and has entered real-time services. However, because the Internet is served by a variety of service providers, it is very difficult to adopt a new architecture or make some modifications on the existing architecture, which makes the existing Internet technology not conducive to supporting mobility and affecting the core The scalability of routing reduces the effectiveness of existing security mechanisms and hinders the development of new network technologies. [0003] In order to solve the rigidity of the Internet and stimulate innovation in future network research, the method of ne...
