Embodiment Construction

[0025] In the embodiment of the present invention, the ultra-fast Ethernet service can be transmitted in the following two ways.

[0026] 1. Distribute the received data stream into n virtual channels in units of 66B code blocks, and add the LLM (Logical Lane Marker) to the alignment marker AM (align marker) of the n virtual channels synchronously, The n channels of virtual channels are synchronously mapped to n channels of ODTUk.mTS (optical channel data tributary unit-k including m time slots, optical channel data tributary unit k including m time slots) in a one-to-one manner. The n channels of ODTUk .mTS is multiplexed into multiple OPUk, and each OPUk is packaged into ODUk and OTUk in turn, and transmitted through multiple OTUk DWDM (Dense Wavelength Division Multiplexing) optical modules. Wherein, one virtual channel corresponds to one or more time slots of one ODTUk, and the value m of the time slot depends on the rate of the virtual channel.

[0027] 2. Distribute the...

Abstract

The invention discloses a method and a device for transmitting an ultra high-speed ethernet service. The method comprises the steps of distributing an ultra high-speed ethernet service data stream into a plurality of virtual channels; wherein, the speed of the ultra high-speed ethernet service data stream is greater than 100 GB; synchronously adding the marks of the plurality of virtual channels; branching channels to map the data of the plurality of virtual channels; and combining the data of the plurality of virtual channels and transmitting. The method employs a channeled transmission mode to transmit the ultra high-speed ethernet service transparently, and the ultra high-speed ethernet service is mapped to reduce the complexity of the ultra high-speed ethernet service into a low-speed ethernet service processing level, so that the realization difficulty is reduced.

Description

technical field [0001] The invention relates to the field of transmission network technology, in particular to a method and device for transmitting ultra-high-speed Ethernet services. Background technique [0002] OTN (optical transport network, optical transport network) as the core technology of the next generation transport network, including technical specifications of the electrical processing layer and optical processing layer, with OAM (operation, administration and maintenance, operation, management and maintenance), TCM (Tandem Connection Monitoring, serial connection monitoring) and out-of-band FEC (forward error correction, forward error correction) capabilities can realize flexible scheduling and management of large-capacity services, and have increasingly become mainstream technologies in backbone transport networks. In the electrical processing layer, the "digital encapsulation" structure defined by OTN technology can realize the management and monitoring of cu...
