Embodiment Construction

[0050] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0051] In order to solve the problems of redundant traffic paths and weak protection against single node failures in the prior art, the present invention proposes a VPLS-based Ethernet networking mode, configuring a half-open H-VPLS ring by the first half-ring and the second semi-ring, and the first semi-ring communicates with the second semi-ring through the first PE device, and the second semi-ring communicates with the first semi-ring through the second PE device; then, configure the first PE device and the second PW between PE devices, and the first PE device and the second PE device are configured not to actively establish a Label Distribution Protocol (LDP, Label Distribution Protocol) connection by default, but to passively establish a PW connection.

[0052] Based on the above networking mode and configuratio...

Abstract

The invention discloses an Ethernet and multicast stream processing method based on VPLS; a configured semi-opening H-VPLS ring comprises a first semi-ring and a second semi-ring, the first semi-ring is communicated with the second semi-ring through first PE equipment, and the second semi-ring is communicated with the first semi-ring through second PE equipment; the first PE equipment proactively establishes PW connection with the second PE equipment through BFD when the failure of the first semi-ring is detected and the second semi-ring is normal; and the second PE equipment proactively establishes PW connection with the first PE equipment through BFD when the failure of the second semi-ring is detected and the first semi-ring is normal. The Ethernet and multicast stream processing method based on VPLS prevents traffic redundancy and bandwidth waste, and can well protect the business in case of single node failure.

Description

technical field [0001] The invention relates to the networking technology of the Ethernet, in particular to a VPLS-based Ethernet and a multicast flow processing method thereof. Background technique [0002] There are usually three kinds of failures in the MAN, namely: 1. A node or a link failure in the MAN; 2. The link failure between the MAN and the core Internet access; Node failure. These failures can seriously affect the robustness and stability of the network. [0003] Aiming at the problem of link failure, the prior art proposes a virtual private local area network service (VPLS, Virtual Private LAN Service) networking technology, such as figure 1 Shown is a VPLS-based distribution model in the prior art, in which all Provider Edge (PE, Provider Edge) devices are connected to User Edge (CE, Custom Edge) devices. In the prior art, the application figure 1 The distribution model of VPLS, a MAN solution using the VPLS networking technology of the entire MAN network, ...
