Problems solved by technology

At this time, if the DHCPv4-over-IPv6 dynamic address configuration mechanism is adopted, only TI can obtain the IPv4 public address from TC, and the ICP server in the IDC network cannot obtain the public IPv4 address, so that it cannot provide services for the IPv4 Internet

Embodiment Construction

[0017] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all implementations. Exhaustive list of examples.

[0018] The present invention proposes a method for establishing a 4over6 tunnel in an Internet Data Center (IDC, Internet Data Center) transitional network. The method mainly involves tunnel initiation point TI and tunnel convergence point TC equipment. The tunnel initiation point TI is a dual-stack gateway device deployed at the boundary between the IDC network and the IPv6 access network. Its downlink interface is connected to the IDC network, and its uplink interface is connected to the IPv6 access network. The tunnel convergence point TC is a dual-stack router deployed at the boundary betwee...

Abstract

Disclosed is a method for establishing a 4over6 tunnel in an IDC transition network. The invention provides a method for an IPv4 data center accessing an IPv6 network to provide services for Internet users. An ICP server in an IDC Network can retain an IPv4 public address which is distributed and configured by the IDC Network for the ICP server, and the ICP server can access an IPv4 Internet via an IPv6 network to provide services for IPv4 terminal users only by upgrading IPv4 gateway equipment of the ICP server. The method disclosed by the invention only requires upgrading of the IDC Network and IPv6 network gateway equipment, can reduce the influence on IDC network deployment and address planning to a large extent, and can ensure the capability to provide Internet access services.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for establishing a 4over6 tunnel in an IDC transition network. Background technique [0002] As the global IPv4 address resources have been allocated, the transition of the entire network to IPv6 has become a core technical problem faced by the next generation Internet. During the transition period of IPv6, IPv4 and IPv6 networks will coexist for a long period of time. The 4over6 tunnel transition technology can meet the requirements of IPv4 network to communicate through IPv6 network. This technology deploys a 4over6 tunnel convergence point TC (Tunnel Concentrator) at the junction of the IPv6 network and the IPv4 Internet, and deploys a 4over6 tunnel initiation point TI (Tunnel Initiator) between the IPv4 network and the IPv6 network, and establishes an IPv4-over- The IPv6 tunnel realizes the transmission of IPv4 packets across the IPv6 network, so that the IPv4...
