Abstract

The embodiment of the present invention discloses an optical network system, which relates to the field of communication technology. The optical network system can prevent adverse situations such as data loss and data interruption during the switching time of switching the service connection to the corresponding protection path, and ensures that the optical normal operation of the network system. This optical network system includes: an active node, a first standby node, a second standby node, a first uplink optical splitter, a second uplink optical splitter, and external network equipment, the active node and the at least two standby The nodes include respective clients, the first uplink optical splitter is set corresponding to the first backup node, and the second uplink optical splitter is set corresponding to the second backup node.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an optical network system. Background technique [0002] With the continuous development of Wavelength Division Multiplexing (WDM) technology, the transmission capacity of a single optical fiber continues to achieve geometric growth, and the optical network has become the most promising at present and in the future due to its huge data and service carrying capacity. communication backbone network infrastructure. In such a high-speed and large-capacity optical transport network, once a network component (link or node) fails, a large amount of data and services will be lost. In order to avoid or reduce the impact of network component failure on network services, network survivability protection technology has always been an important issue in the field of optical network research and application. [0003] The inventors have found that the traditional optical network surviv...
