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...

Abstract

The invention discloses a method for data transmission, a transmitter and a receiver. The method comprises the steps of obtaining constant bit rate (CBR) service data; performing physical coding sublayer (PCS) coding on the CBR service data; inserting a rate adaptation code block into a PCS code stream obtained by the PCS coding for rate adaptation of the PCS code stream; mapping the the PCS rate stream after adaptation into N time slots of a flexible Ethernet (FlexE) frame, where N is a positive integer greater than or equal to 1; and transmitting the FlexE frame, wherein the FlexE overhead of the FlexE frame includes information indicating the N time slots corresponding to the PCS code stream. The method for the data transmission, the transmitter and the receiver according to the embodiment of the invention can realize flexible Ethernet mapping of the CBR service data and enhance the carrying capacity of the 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 (Fast Ethernet, FE) and 1 Gigabit Ethernet (Gigabit Ethernet, GE) have gradually evolved to the current 100GE Ethernet and 400GE Ethernet being defined by IEEE. 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 ...
