Problems solved by technology

[0002] In the scenario of mixed deployment of Internet Protocol (IP, Internet Protocol) network and optical network, the IP network and optical network are maintained separately, and manual configuration is required to implement ) traffic interworking, that is to say, what impact will the link failure on the optical side have on the business on the IP side? Only when the failure actually occurs can it be discovered through the IP side and service alarms. In this way, users cannot perceive it in advance of

Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. 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 arbitrarily with each other.

[0022] In the scenario of IP+optical synergy, the IP-side service, network and optical-side service / network association can be established through the IP+optical synergy software-defined network (SDN, Software Defined Network) controller (hereinafter referred to as the controller for short). ,Such as figure 1 As shown, the inventors of the present application have found through research that if the link failure is simulated by the IP+optical cooperative SDN controller, the link failure between the IP device and the optical device, such as an optical layer link or a user-side interface link,...

Abstract

The invention discloses a fault sensing method and device and a controller. The method comprises the steps that the controller carries out mirroring processing on current network resources; and the controller performs fault simulation on the network resource obtained by mirroring according to the obtained fault sensing condition, and obtains an influence result of the fault on the network. According to the invention, the influence of the fault on the network can be automatically obtained in an IP+ light cooperation scene, and an effective and visual evaluation method for the network quality and network resources is provided for network operation and maintenance personnel.

Description

technical field [0001] The present application relates to, but is not limited to, especially a fault sensing method, device and controller. Background technique [0002] In the scenario of mixed deployment of Internet Protocol (IP, Internet Protocol) network and optical network, IP network and optical network are maintained separately, and manual configuration is required to realize ) traffic interworking, that is to say, what impact will the link failure on the optical side have on the business on the IP side? Only when the failure actually occurs can it be discovered through the IP side and service alarms. In this way, users cannot perceive it in advance of. Contents of the invention [0003] The present application provides a fault sensing method, device, and controller, which realize automatic learning of the impact of faults on the network in the scenario of IP+optical collaboration. [0004] This application provides a fault perception method, including: [0005] ...
