Problems solved by technology

[0006] During the research and practice of the existing technology, the inventors found that the existing technology has the following problems: GFP-F encapsulation needs to be processed packet by packet after extracting data at the MAC layer, which brings a large delay compared to GFP-T encapsulation
When transmitting some high-quality audio and video services and storage backup data services, it is difficult to meet the transmission quality requirements with GFP-F encapsulation

Embodiment Construction

[0029] The embodiment of the present invention provides a coded block format conversion method and a coded block format conversion device. When used to transmit business data, the coded block of the business data can be converted to the coded block format to avoid unsupported transmission of business data. The problem of encoding block format realizes simple processing and low delay when transmitting business data, and improves the performance of transparent transmission of business data. The method provided by the embodiment of the present invention is described in detail and illustrated as follows:

[0030] see figure 1 , a flow chart of Embodiment 1 provided for the method of the present invention, including:

[0031] 101: When the identifier of the first encoding block is the first identifier, add an identifier of a flag bit to the data word part of the first encoding block to obtain a second encoding block. For example, the first encoding block is a 64B / 66B encoding blo...

Abstract

The invention discloses a method for converting a coding block format and a device used for converting the coding block format. The method comprises: when business data is transported, the received coding blocks are converted into the supported coding block format when being packaged by carrying out coding block format conversion on the received business data in the up direction, and the receivedcoding blocks are converted into the coding block format supported by a transmission line by carrying out the coding block format conversion on the received business data in the down direction. The invention has the advantages as follows: the problem that the coding block format is not supported when the business data is transported is avoided, simple processing and low time delay when the business data is transported are realized, and the transparent transmission performance of the business data is enhanced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for encoding block format conversion and a device for encoding block format conversion. Background technique [0002] A data service, for example, an Ethernet service in the data service is transmitted through a transmission network based on a Generic framing procedure (GFP, Generic framing procedure) protocol. GFP basic frame format see figure 1 , during the transmission process, GFP completes the encapsulation of data services, and realizes the framing function in the mapping to the transmission network, such as mapping to the Synchronous Digital Network (SDH, Synchronous Digital Hierarchy), Optical Transport Network (OTN, Optical Transport Network) The framing function is implemented in the frame, so that the demultiplexing module can recover the data. see figure 2 , currently using frame encapsulation mode (GFP-F, GFP Framed Mapped) and transparent...
