Embodiment Construction

[0052] The basic idea of ​​the present invention is: by setting more than one protection entity for the working entity, and setting the endpoint bridge for the working entity and the protection entity in the Ethernet protection domain, when the endpoint bridge detects that the working entity fails or the fault disappears, it will pass the modification The outgoing interface of the forwarding entry of the current service performs service switching, and the present invention can well realize fast protection for TESI, enhances the robustness of the PBB-TE network, and improves network performance.

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0054] Figure 5 Be the flowchart of the protection method of Ethernet tunnel of the present invention, as Figure 5 Shown, the protection met...

Abstract

The invention discloses a method for protecting an Ethernet tunnel. More than one protective entity is provided for a working entity in an Ethernet protective domain, and the working entity and the protective entity have the same two endpoint bridges. The method comprises the following steps of: when one endpoint bridge detects the fault of the working entity, switching the protected tunnel on the working entity to the protective entity, namely modifying the output port of a forwarding item of the protected tunnel associated with the port of the working entity into the port of the selected protective entity, and informing the other endpoint bridge of port switching. The invention discloses a device for protecting the Ethernet tunnel at the same time. The method and the device can well realize quick protection of transfer of electrostatic images (TESI), enhance the robustness of a provider backbone bridge-traffic engineering (PBB-TE) network, and improve the performance of the network.

Description

technical field [0001] The invention relates to the protection switching technology in the Ethernet, in particular to a protection method and device for the Ethernet tunnel. Background technique [0002] With the introduction of the concept of Carrier Ethernet (CE, Carrier Ethernet), in order to meet the continuous high data rate requirements of telecom networks, the connection-oriented Ethernet technology - Provider Backbone Transport (PBT, Provider Backbone Transport) was also launched in 2005 surfaced in October. Since then, operators at home and abroad have adopted PBT technology to form a network, which provides a good start for the development of PBT technology in the metropolitan area network. [0003] The basis of PBT technology is the Provider Backbone Bridge (PBB, Provider Backbone Bridge) technology defined by Institute of Electrical and Electronics Engineers (IEEE, Institute of Electrical and Electronics Engineer) 802.1ah. IEEE refers to PBT technology as the ca...
