Embodiment Construction

[0027] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0028] The technical scheme of the present invention is aimed at broadband access equipment (including MSAN (multi-service access network), DSLAM (digital subscriber line access multiplexer) or OLT (optical line terminal)) to achieve QoS in an IPv6 network.

[0029] The main idea of ​​the present invention is to implement a two-layer QoS mechanism through Traffic Class+Flow label; the terminal is in the routing mode, and the priority of the inner layer is mapped to the Flow label of the outer layer through the dual-stack lite method. ; Access Network (AN, Access Network) implements priority according to TrafficClass+Flow label.

[0030] The realization principle of the present invention: to realize the QoS capability of the two-layer access network, the two-layer TC labels must be marked to meet the requirements.

[0031] 1. Broadband access equipment (may refer to...

Abstract

Provided is a method and system for quality of service (QoS) control in internet protocol version 6 (IPV6), and the method comprises: after receiving a data flow from a user port, a broadband access device maps a QoS priority of a user side port service to an IP differentiated services code point (DSCP) priority; the broadband access device performs a tunnel encapsulation, and maps the IP DSCP priority to an outer layer flow label; after receiving the data flow forwarded by the broadband access device, a layer-2 access network maps the flow label to a priority label of a switch device, and then the whole layer-2 access network performs forwarding according to the QoS priority in the priority label of the switch device. Application of the present invention resolves the problem of providing QoS capabilities for different priority data of an IPV6 tunnel in the whole access network.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and system for controlling quality of service (QoS) in IPV6. Background technique [0002] The transition to IPv6 must be gradual. Considering that there are already a large number of networks and nodes connected to the Internet, people cannot accept a large number of upgrades in switching forms. This upgrade requires network administrators to find and install a new version of network software for every host and router on the Internet. Considering that there are many different platforms running IPv4, this approach will be difficult to achieve. [0003] The transition to IPv6 will also be a relatively slow process. It is expected that IPv4 and IPv6 will coexist for a long time, perhaps forever. Most transition strategies rely on the two-way method of protocol tunnels, encapsulating IPv4 packets from IPv4 islands in IPv6 packets, then transmitting them in the IPv6 network...
