Problems solved by technology

When the MPLS technology is used in combination with the Ethernet switch hardware platform, and the SFU is used as the Ethernet switch chip in the switch, only Layer 2 Ethernet packets can be supported in the Ethernet switching network, and packets such as ATM and MPLS cannot provide direct Therefore, when the Layer 2 Ethernet switching chip must be used as the internal switching hardware of the switching device, the existing technology cannot provide more value-added services

Embodiment Construction

[0028] The invention provides an Ethernet switching device and method for realizing MPLS message forwarding. The core of the invention is to set a private MAC address conversion module and a public MAC address conversion module in the Ethernet switching device. The private MAC address does not conflict with the common public MAC address forwarded normally. When the MPLS message enters the Ethernet switching device, the private MAC address conversion module encapsulates the private MAC address for the message, and the Ethernet switching device converts the private MAC address according to the private MAC address. The message is forwarded to the port corresponding to the destination public MAC address, thereby realizing forwarding of the MPLS message on the Ethernet switching device.

[0029] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the ...

Abstract

Core of the invention is conversion module of private MAC address and conversion module of public MAC address in Ethernet exchange equipment. When MPLS message enters into Ethernet exchange equipment, the Ethernet exchange equipment packages the message with private MAC address, and forwards the message to the port corresponding to destination public MAC address based on private MAC address so as to realize forwarding MPLS message through Ethernet exchange equipment. Thus, on second layer and / or third layer of Ethernet exchange chip, the invention also can support multiple operations including PWE3, L2VPN and MPLS flux engineering etc. based on MPLS.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an Ethernet switching device and method for realizing multi-protocol label switching (Multi-Protocol Label Switching; MPLS) message forwarding. Background technique [0002] With the widespread application of Ethernet technology in enterprise networks, Ethernet technology is increasingly becoming the most important and common network solution in the access network, access bearer network, and even backbone network of carrier networks. In the traditional backbone network, IP / MPLS technology also replaces the Asynchronous Transmitting Mode (ATM) technology and becomes the final solution. In this form, MPLS technology is moved down to the access network and access bearer network, carried on the Layer 2 Ethernet network, and provides connection-oriented service channels, so that it is possible to provide end-to-end system solutions for users and services . [0003] For...
