Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0049] Before explaining the embodiment of the present application in detail, the application scenarios involved in the embodiment of the present application are firstly introduced.

[0050] With the growth of service traffic, the fixed-rate interface provided by OTN can no longer meet the interconnection requirements. For this reason, the industry has proposed N*100G, N*200G and N*400G FlexO group interfaces, which are used to carry OTUCn signals to realize inter-domain interface interconnection of OTUCn signals. Wherein, the FlexO group interface may include multiple physical ports, and the FlexO group interface of N*100G means that the multiple physical ports included in the FlexO group interface are all 100G. The N*200G Flex...

Abstract

The application discloses a service data processing method and equipment, which belong to the technical field of communication. In this application, the sending end device can generate an OTUXn signal carrying service data, generate and send at least n FlexO frames according to the OTUXn signal, wherein at least r FlexO frames in the n FlexO frames carry service verification data , the service check data can be used to restore the service data when the bit error rate of the k FlexO frames is greater than the reference bit error rate. In this way, if no more than r physical ports among the physical ports included in the FlexO group interface fail, or, due to other reasons, the bit error rate of no more than r FlexO frames is greater than the reference bit error rate, then the receiving end device can The service data is restored through the received FlexO frame, realizing lossless restoration of the service data.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a service data processing method and device. Background technique [0002] With the growth of service traffic, the fixed-rate interface provided by the optical transport network (OTN) can no longer meet the interconnection requirements. For this reason, the industry proposes a flexible optical transport network (flexible optical transport network, FlexO) group interface. Through this group of interfaces, the OTN equipment transmits an Optical Transport Unit Cn (Optical Transport Unit Cn, OTUCn) signal carrying service data. Wherein, the FlexO group interface may include multiple physical ports, and the OTN device modulates the OTUCn signal onto multiple optical carriers to form multiple optical carriers carrying the OTUCn, and transmit through the multiple physical ports included in the FlexO group interface. [0003] If one of the multiple physical ports u...
