Embodiment Construction

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0023] Such as figure 1 As shown, this embodiment discloses a link non-load sharing protection method, which includes the following steps: creating a non-load sharing group between the user access device and the access network, and only adding two group members, one is the main link and the other is the backup link. Usually, the main link is used as the default link for forwarding data, while the backup link is idle for a long time, and the main link and the backup link The failure detection mechanism is respectively configured and the event interruption is registered. When a failure of the main link is detected, the main link DOWN switches the data flow of the main link to the backup link; similarly, when a failure...

Abstract

The invention relates to a link non-load sharing protection method. The method comprises the following steps: 1, ; a non-load sharing group is created between user access equipment and an access network; only two group parts are added into the non-load sharing group; one is a primary link, the other link is a standby link; generally, the main link is used as a default link for forwarding data, thestandby link is in an idle state for a long time, the main link and the standby link are respectively configured with a fault detection mechanism and a registration event is interrupted, and when themain link is detected to have a fault, the main link DOWN switches the data flow of the main link to the standby link; similarly, when it is detected that the standby link breaks down, the standby link DOWN switches the data flow of the standby link to the main link. The problem that a user cannot use a network or is in a network interruption state for a long time when a link fails is solved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a link non-load sharing protection method. Background technique [0002] Currently, based on the topology of the entire communication network, the access layer, aggregation layer, and core layer all have mature protection mechanisms, such as LSP / PW protection, ring network protection, etc., but there is a lack of communication between user access devices and the access layer. An effective protection measure, when the link between the user's access device and the access network fails, the communication between users will be interrupted, resulting in the failure of normal communication between users. Contents of the invention [0003] Aiming at the technical problems in the prior art, the invention provides a link non-load sharing protection method, which solves the problem that when a link fails, users cannot use the network or are in a state of network interruption for a...
