Problems solved by technology

Obviously, this method does not provide the processing when signal degradation (SD, Signal Degrade) occurs on the T-MPLS ring network. Although SD will not make the normal transmission of the business, it will affect the network service quality of the business on the T-MPLS ring network. which in turn affects the user experience

Embodiment Construction

[0048] The flow of the implementation method of ring network protection in the embodiment of the present invention is as follows figure 1 shown, including the following steps:

[0049] Step 101: the nodes at both ends of each span of the path on the ring network perform SD alarm detection on the span;

[0050] Wherein, the ring network refers to a T-MPLS ring network.

[0051] Here, the nodes at both ends of each span of the path on the ring network perform SD alarm detection on the span as follows:

[0052] Step a1, presetting the packet loss rate threshold;

[0053] Among them, the general packet loss rate threshold is 10 -6 to 10 -3 time, and according to the network service quality setting required by the business on the ring network, the higher the required network service quality, the smaller the set packet loss rate threshold, so as to ensure the network service quality of the business.

[0054] Step b1, the node segment layer (TMS) at both ends of each span segmen...

Abstract

The invention discloses an implement method of ring network protection, which comprises: nodes at the two ends of all span sections of a path on the ring network are used for carrying out SD alarm detection on the corresponding span sections; the nodes send the detected SD alarm into a protection node of the path; and protection switching treatment is carried out on the business on the span sections having the SD alarm when the SD alarm is received by the protection node. The invention also discloses an implement system of the ring network protection, which comprises all the span sections, the nodes and the protection node on the path of the ring network. The method and the system of the invention can ensure the QoS of network services of the business on the T-MPLS ring network.

Description

technical field [0001] The present invention relates to operation management and maintenance (OAM, Operation Administration and Maintenance) technology, in particular to a method and system for realizing ring network protection of Transport Multi-Protocol Label Switching (T-MPLS, TransportMPLS). Background technique [0002] T-MPLS is a connection-oriented packet transport network proposed to meet the needs of operators for packet transport networks. It removes some complex functions of the data forwarding plane in Multi-Protocol Label Switching (MPLS, Multi-Protocol Label Switching), and can Realize the effective control and use of transport network resources, and increase the connection-oriented OAM to realize the protection function of T-MPLS network. [0003] At present, the implementation method of T-MPLS ring network protection is: when a signal failure (SF, Signal Fail) on the T-MPLS ring network is detected, a corresponding protection switching operation is performed...
