Problems solved by technology

This technology is only applicable to a pure IPv4 environment. In an IPv6 transition environment, such as a light dual-stack tunnel environment, the current BRAS device cannot detect the inner layer packet because the downlink data has encapsulated the IPv6 packet header on the outer layer before entering the BRAS. IPv4 source address, so this technology cannot be used in the IPv6 transition environment, resulting in IPv6 transition technology covering users unable to use the intelligent speed-up service

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] figure 1 It is a schematic diagram of intelligent speed-up network deployment in the light dual-stack tunnel environment of the present invention. Such as figure 1 As shown, IPv4 packets or IPv4 traffic are transmitted from the core router (CR) to the AFTR device, and the AFTR device adds th...

Abstract

The invention discloses an intelligent speeding-up method, an intelligent speeding-up system, and an AFTR device in a light dual-stack tunnel environment, and relates to the next-generation Internet field. The intelligent speeding-up method is characterized in that the AFTR device is used to detect address information of an input IPv4 message; the AFTR device can be used for the marking of the IP priority of the IPv4 message according to the address information of the IPv4 message, and the ToS field of the IPv4 message can be filled with the IP priority; the AFTR device can be used to package the IPv4 message into an IPv6 message, and the ToS field of the IPv4 message on the inner layer can be copied to the TC field of the IPv6 message on the outer layer, and then the IP priority of the IPv6 message on the outer layer is the same as the priority of the IPv4 message; the AFTR device can be used to forward the packaged IPv6 message to the BRAS, and then the rate control of the TC field of the IPv6 message, which is carried out by BRAS, can be facilitated, and therefore the intelligent speeding-up scheme suitable for the IPv6 transition period in the light dual-stack tunnel environment is provided, and then the intelligent speeding-up based on the business can be supported.

Description

technical field [0001] The invention relates to the field of next-generation Internet, in particular to an intelligent speed-up method, system and address family translation router (Address Family Translation Router, AFTR) device in a lightweight dual-stack (DS-Lite) tunnel environment. Background technique [0002] There are two main types of intelligent speed-up technologies currently in use. One is for omni-directional speed-up customers. The overall bandwidth is increased after the customer makes an application, without distinguishing between services, and lacks the flexibility to increase speed based on business traffic alone. [0003] The other is the intelligent speed-up technology based on the IPv4 network. Its basic principle is: After the user signs up with the content provider (Content Provider, CP) or service provider (Service Provider, SP), the speed-up information is sent to the Remote Broadband Access Server (Broadband Remote Access Server, BRAS), when the da...
