Embodiment Construction

[0041] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0042] In order to solve the problem of serious waste of resources mentioned in the prior art, the embodiment of the present invention provides a ring network wrap-around protection method, which is applied in the packet transmission network, and the processing flow is as follows: image 3 shown, including:

[0043] Step 302, configuring a protection closed-loop path, and binding the protection closed-loop path to all working paths in the packet transport network;

[0044] Step 304 , when the working path fails or the protection switching is manually triggered, bridge the service passing through the bridging point to the protection closed-loop path.

[0045] use as image 3 In the ring network wra...

Abstract

The invention discloses a data transmission method and device. The method comprises the following steps: when working paths are failed or protection switching is triggered manually, bridging a service which passes through a bridging point into a protective closed-loop path, and pressing a path mark of the working path corresponding to a data message into of the service the data message of the service, wherein, the working paths share one protective closed-loop path; and when the data message is sent to a switching point, switching the data message into the corresponding working path for transmission according to the path mark in the data message. The invention further discloses a ring network wrapping method and device. The invention can save path resources and lower configuration management complexity.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and device, and a ring network wraparound protection method and device. Background technique [0002] Ring network segment layer protection (wrapping) In the packet transmission network, one-to-one backup is currently mainly adopted in the way of one-to-one backup, that is, a separate protection path is provided for each working path. In One-to-one Backup mode, in order to protect a working path, you need to configure a protection closed-loop path for protection. For details, see figure 1 ,exist figure 1 Among them, the solid line represents the working path, and the dotted line represents the protection closed-loop path. The working path is NodeA->NodeB->NodeC->NodeD, and the protection closed-loop path is a loop formed among NodeA, NodeB, NodeC, NodeD, NodeE, and NodeF. This protection closed-loop path has no start and end points, and is a co...
