Problems solved by technology

[0004] The traditional technical solution maps a Flex Ethernet service as a whole to an ODUk/ODUflex container. When the Flex Ethernet service exceeds the bandwidth of a single line interface of a traditional OTN network, the bandwidth of the line interface must be upgraded. End-to-end reconstruction of the path leads to high network construction costs of the OTN network
In addition, tw...

Embodiment Construction

[0079] The technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention.

[0080] See figure 1 , figure 1 It is a schematic structural diagram of an optical transport network bearer system for flexible Ethernet services provided in an embodiment of the present invention. As shown in the figure, the optical transport network bearer system for flexible Ethernet services in an embodiment of the present invention may at least include a sending end and Receiving end. Wherein, the sending end and the receiving end may establish a communication connection through the OTN network. The optical transport network bearer system for flexible Ethernet services can realize uplink transmission and downlink transmission. In uplink transmission, the sending end sends Flex Ethernet services to the OTN network, and in downlink transmission, the receiving end receives Flex Ethernet servi...

Abstract

The embodiments of the invention disclose a flexible Ethernet business's optical transport network carrying method and an apparatus wherein the method comprises: extracting a flexible Ethernet business from a flexible Ethernet service layer; performing data division to the flexible Ethernet business to obtain at least two data queues with each data queue carrying a queue identification; mapping each data queue to an optical transport network container which comprises an optical channel data unit k container or a flexible optical channel data unit container; and transporting the various optical transport network containers to the optical transport network. With the embodiments of the invention, the utilization efficiency of the band width could be raised and the optical transport network building cost is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for carrying an optical transport network of a flexible Ethernet service. Background technique [0002] The 802.3-based Ethernet defined by IEEE has been used as a service interface and applied in various occasions. At present, OIF (Optical Internetworking Forum, Optical Internetworking Forum) is discussing the expansion of traditional Ethernet application scenarios to support functions such as sub-rate, channelization, and inverse multiplexing for Ethernet services, and calls this Ethernet technology For Flex Ethernet (flexible Ethernet). For example, for the sub-rate application scenario of the Ethernet service, it is supported to transmit the 50G Ethernet service using the existing 100GE PMD (Physical Medium Dependent, physical medium dependent sublayer). For the inverse multiplexing scenario of Ethernet services, it supports the transmission of 20...
