Abstract

The invention discloses a broadband user application traffic identification method, device and system. The method includes: when the IPv4 application traffic passes through, the address family conversion router performs dyeing and encapsulation on the IPv4 application traffic; the address family conversion router performs synchronous dyeing processing on the outer tunnel according to the dyed traffic in the inner layer of the tunnel; Outer colored traffic identifies IPv4 application traffic. The present invention does not change the network networking structure, and the address family conversion router dyes and encapsulates the application traffic, and synchronizes the inner and outer layers of the tunnel, so that the broadband remote access server can identify the IPv4 application traffic according to the dyed traffic on the outer layer of the IPv6 tunnel.

Description

technical field [0001] The invention relates to the technical field of IPv6 in data communication, in particular to a broadband user application traffic identification method, device and system. Background technique [0002] With the exhaustion of IPv4 addresses, telecom broadband will gradually develop IPv6 users, realize the distinction of user application traffic, and provide a technical basis for differentiated service guarantee. [0003] Ds-Lite is a dual-stack technology adopted by telecom IPv6 users. The data flow of broadband users accessing the IPv4 domain is encapsulated into the IPv4-in-IPv6 tunnel and transmitted in the IPv6 network, while the IPv6 data flow is directly transmitted through the IPv6 network. In the centralized Ds-lite mode, the IPv4 and IPv6 data streams of broadband users are mixed together, and application traffic cannot be distinguished, and traffic planning and service guarantee cannot be realized. Contents of the invention [0004] In view...
