Abstract

The embodiment of the invention discloses a processing method of data in an OTN (optical transport network). The processing method comprises the following steps that Ethernet data frames sent by an etheric plate net plate are received and cashed through an ILK (Interlaken) interface; the Ethernet data frames are encapsulated into GFP (generic framing procedure) data frames; and the GFP data frames are mapped into an OTN virtual container to form OTN data frames, and in addition, the OTN data frames are transmitted to a corresponding transparent transmission plate through a cross plate. The embodiment of the invention also discloses a processing device and a processing system of data in the OTN. When the method, the device and the system are adopted, the problem of too many Ethernet interfaces in the prior art can be solved.

Description

technical field [0001] The invention relates to the communication field, in particular to a data processing method, device and system in an OTN optical transport network. Background technique [0002] In the current product, the Ethernet board does not support the OTN (Optical Transport Network, OTN for short) service processing function, and the Ethernet board encapsulates the input ETH (Ethernet, Ethernet, ETH for short) transmission in the pipeline. [0003] In the prior art, the scheme of connecting the Ethernet board and the transparent transmission board: [0004] In order to connect the Ethernet network board with the transparent transmission board B, a transparent transmission board A must be added. The function of the transparent transmission board A is to encapsulate the ETH service into the OTN particle, and then cross the encapsulated ETH service to the transparent transmission board through the cross-connection board B. The transparent transmission board B dem...
