Description

METHOD AND APPARATUS OF CONSTRUCTION FOR PERSONANLIZED VIRTUAL NETWORK}

The present invention relates to a method and apparatus for configuring a virtual network, and more particularly, an individual configures his or her own virtual network, and through his or her own walled garden service through the access qualification and approval of the virtual network. It relates to a method and an apparatus for providing a.

A virtual private network (hereinafter referred to as a VPN) is a technology for obtaining an effect like a private network by using a public switched network (hereinafter referred to as a public network) such as the Internet. It is a security solution that is in the spotlight with the activation of the Internet in that it can form a more connected and secure network at a much lower cost than the private network used.

In addition, the VPN can establish a logical line regardless of the physical network configuration on the public network, such as the Internet, to establish a virtual private communication network to ensure stability in the private network without establishing a separate private network.

In other words, a VPN utilizes a public network, such as a low-cost Internet, to connect only a specific target, such as a headquarters, a data center, a branch office, a mobile worker or a customer, to whom it has been granted access. This can be called.

Instead of leasing a private network by leasing a dedicated line for every company individually, a VPN utilizes a widely spread public network to significantly reduce costs while maintaining communication security while providing almost the same service as a leased line. It is suggested as an alternative to provide.

 Key technologies for configuring such a VPN include tunneling technology and encryption technology. Tunneling technology used in VPN is a technology that forms a virtual tunnel that is not influenced by the outside on the Internet, and sends and receives information, and establishes a session using mutually promised protocol from start point to end point. Data transmitted through the encryption or authentication tunnel thus formed is guaranteed security services such as confidentiality, integrity and authentication.

Meanwhile, Korean Patent Publication No. 2001-0107790 (a virtual private network construction method and a virtual private network gateway using the same) uses an internal protocol different from a public network protocol, for example, IPX, Appletalk, SNA, etc. through Layer 3 of a communication protocol. By allowing private networks to build a VPN using a public network, this paper suggests a way to build a VPN at low cost without using a dedicated line, which is expensive for leasing a circuit.

However, such a VPN has limitations mainly focused on enterprise security and efficient use of the network. That is, an individual who is not an enterprise connects to a VPN and configures his or her own virtual network within the VPN, designates a member who participates in his or her virtual network, or specifies qualifications, so that a specific person or qualification is preferred by the individual. You can't build separate virtual networks for people.

Accordingly, there is a need for a network technology that allows an individual to configure a social network service (SNS) or a virtual community on their own VPN on the Internet.

In order to solve the above problems of the prior art, the present invention provides a method and apparatus for configuring a personalized virtual network in a virtual private network (hereinafter referred to as a VPN).

In addition, the present invention provides a method and apparatus for providing a neighboring virtual network pool or a higher virtual network pool so as to be connected to other virtual networks, so as to conveniently search and select a virtual network to be connected. to provide
