Embodiment Construction

[0048] The present invention provides a method and system for an Ethernet provider edge device (Provider Edge Device, PE) to perform service switching. The edge device sends notification information, and after receiving the notification information, the edge device of the carrier at the sending end performs service switching immediately.

[0049] The present invention will be described in detail below in conjunction with the accompanying drawings. The above-mentioned operator edge equipment includes PEs such as routers, switches, and third-layer switches. The processing flow chart of the specific implementation of the method of the present invention is as follows image 3 shown, including the following steps:

[0050] Step 3-1: After the PE at the receiving end fails to receive the service packets from the PE at the sending end within the set time, it performs service switching, and at the same time, sends notification information to the PE at the sending end.

[0051] After ...

Abstract

The provided business switch for peripheral device of Ethernet provider comprises: for switching business, the Ethernet receiving device sends notice information to the sending peripheral device; the latter receives information for business switch. This invention can reduce switching time.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and a system for performing service switching on an edge device of an Ethernet operator. Background technique [0002] Mac-in-Mac (Ethernet solution) is a key technology of PBB (Provider Backbone Bridges, operator backbone bridge) given by IEEE (Institute of Electrical and Electronics Engineers) 802.1ah draft. Mac-in-Mac isolates the customer Ethernet network from the carrier Ethernet network by adding an outer layer MAC (Media Access Control) header and service instance ID to the outer layer of the customer Ethernet frame, so that it can solve the problem of A series of problems caused by the application without layers. [0003] IEEE 802.1ag proposes a draft of connectivity error management for Ethernet OAM (Operation Maintenance and Management), which defines a set of Ethernet end-to-end connectivity detection, fault location and isolation means. The draft includ...
