Abstract

The invention discloses a method, a transmitter and a receiver for data transmission. The method includes: obtaining CBR service data with a fixed bit rate; performing PCS encoding on the CBR service data; Insert a rate adaptation code block into the PCS code stream to perform rate adaptation on the PCS code stream; map the adapted PCS code stream to N time slots of the flexible Ethernet FlexE frame, where N is greater than or equal to 1 is a positive integer; sending the FlexE frame, wherein the FlexE overhead of the FlexE frame includes information for indicating the N time slots corresponding to the PCS code stream. The method for data transmission, transmitter and receiver of the embodiments of the present invention can realize the mapping of flexible Ethernet to CBR service data, and improve the carrying capacity of flexible Ethernet.

Description

technical field

[0001] The embodiments of the present invention relate to the communication field, and more specifically, relate to a method for data transmission, a transmitter and a receiver. Background technique

[0002] The 802.3-based Ethernet defined by the Institute of Electrical and Electronics Engineers (IEEE) has been used as a service interface and applied in various occasions. With the rapid development of communication technology, the rate of Ethernet is also gradually increasing, from 10M Ethernet, Fast Ethernet (FastEthernet, FE) and 1 Gigabit Ethernet (Gigabit Ethernet, GE), etc. have gradually evolved to the current 100GE Ethernet and IEEE are defining 400GE Ethernet. The rapid popularization of Ethernet has promoted the evolution of Ethernet from a simple interface technology to a network technology similar to a transport network.

[0003] Currently, the Optical Internet Forum (OIF) is discussing the expansion of traditional Ethernet application scenarios...

Embodiment Construction

[0139] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0140] First, a brief introduction is given to related concepts involved in the embodiments of the present invention.

[0141] Flexible Ethernet (Flexible Ethernet, FlexE): Similar to OTN, FlexE has the concepts of FlexE client layer and FlexE service layer. The FlexE client layer mainly supports aggregation of client signals, such as 10G, 25G, 40G and N*50G Ethernet interfaces. The FlexE service layer is mainly used to carry the functional layer of F...
