Problems solved by technology

[0003] However, in the current IPv6 network, the traffic is still relatively small, the most important reason is that the number of users is small, and the types of network services provided by users using IPv6 are still relatively small
There is a phenomenon in the current CNGI network: the egress bandwidth of IPv4 is saturated or oversaturated, while the egress bandwidth of IPv6 is hardly used

Embodiment Construction

[0053] The core idea of ​​the present invention is: the dual-stack router broadcasts the tunnel port address of setting up the IPv6 tunnel itself in the IPv6 network according to the attribute configuration received, and sets up the IPv6 tunnel with the opposite end; further, the dual-stack router also according to the received IPv4 routing strategy Set the next hop address of some IPv4 traffic as the tunnel egress, so that some IPv4 traffic is automatically sent through the pre-established IPv6 tunnel, improving the sending efficiency of IPv4 traffic.

[0054] The present invention provides a method for sending IPv4 traffic in an IPv6 network, such as image 3 shown, including:

[0055] Step s301, the dual-stack router establishes an IPv6 tunnel with the opposite end according to the received attribute configuration;

[0056] Step s302, the dual-stack router sets the next-hop address of the IPv4 traffic that needs to be sent through the IPv6 tunnel according to the routing p...

Abstract

The invention discloses a method for sending IPv4 flow in an IPv6 network, including the following steps: a dual-stack router establishes an IPv6 tunnel between the dual-stack router and an opposite terminal according to received attribute configuration; the dual-stack router sets a next-hop address of the IPv4 flow needing to be sent through the IPv6 tunnel according to a received routing strategy of the IPv4 flow sent by the opposite terminal; the next-hop address is a tunnel exit address of the IPv6 tunnel; and when receiving the IPv4 flow needing to be sent through the IPv6 tunnel, the dual-stack router sends the IPv4 flow to the opposite terminal through a tunnel exit of the IPv6 tunnel according to the next-hop address. In the invention, part of the IPv4 flow is automatically transmitted through the IPv6 network, thus improving the efficiency for sending the IPv4 flow through the IPv6 tunnel.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for sending IPv4 traffic in an IPv6 network. Background technique [0002] At present, my country's CNGI (China's Next Generation Internet, China's Next Generation Internet) network construction is accelerating, and various colleges and universities are actively applying for CNGI resident network construction projects. After the project is completed, my country's CNGI network can be said to be the largest in the world. The largest IPv6 (Internet ProtocolVersion6, Internet Protocol Version 6) Internet. The appearance of IPv6 solves the problem of insufficient IPv4 addresses, and has obvious improvements in address capacity, security, network management, mobility, and quality of service. IPv6 is not compatible with IPv4, but IPv6 is compatible with other protocols in all TCP / IP (Transmission Control Protocol / Internet Protocol) protocol suites, so IPv6 can completely re...
