Service carrying method, equipment and system

Abstract

The invention provides a service carrying method, equipment and a system. The method comprises the steps that sender equipment acquires a flexible Ethernet (FlexE) client signal; the FlexE client signal is converted into a FlexE service frame, wherein the FlexE service frame comprises at least one first overhead code block and at least one data code block, the at least one first overhead code block is used for carrying overhead information of the FlexE client signal, and the at least one data code block is used for carrying payload information of the FlexE client signal; the FlexE service frame is mapped to one or multiple time slots of a physical channel to generate a FlexE overhead frame, wherein the FlexE overhead frame comprises a second overhead code block, and the second overhead code block is used for carrying overhead information of the FlexE overhead frame; and the FlexE overhead frame is sent out through the physical channel. According to the method, the FlexE client signal is converted into the FlexE service frame, the overhead information of the FlexE client signal is carried by the FlexE service frame, and then end-to-end network management and monitoring on the FlexEclient signal can be achieved.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a method, device and system for service bearing. Background technique [0002] Currently, the Flex Ethernet Implementation Agreement 1.0 (FlexE IA 1.0) interface technology has been standardized in the Optical Internetworking Forum (OIF). FlexE can be applied to data center equipment interconnection, etc., by binding n 100G physical layer devices (PHYs) to transmit multiple FlexE customer services of different rates, such as 10G, n*25G, 40G FlexE customer services, etc. [0003] For long-distance transmission, FlexE can encapsulate FlexE customer services into FlexE signals, and then carry and transmit FlexE signals through an optical transport network (optical transport network, OTN). like figure 1 As shown, the FlexE signal from FlexE101 to FlexE 103, or the FlexE signal from FlexE 103 to FlexE 101 can pass through OTN102, and realize long-distance transmission th...
