Embodiment Construction

[0026] In order to solve the following problems in the prior art: the FlexE 1.0 protocol stipulates that the position of the Flex Shim layer is between the 64 / 66 codec and scrambling and descrambling of the 100G PCS layer, and the PCS layer is artificially divided into two sides, which is not conducive to the system Integrity; the present invention provides a data processing method and device, which will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The first embodiment of the present invention provides a data processing method, the flow of the method is as follows image 3 As shown, including S302 to S304:

[0028] S302. The sending device sets the first overhead codeword of the overhead block as a preset feature value, and inserts the overhead block including th...

Abstract

The invention discloses a data processing method and device. The method comprises the following steps: a sending device sets a first overhead codeword of an overhead block to be a preset feature valueand inserts the overhead block including the preset feature value to a data stream, wherein the overhead block is each overhead block of the data stream to be inserted to a physical coding sub-layerPCS layer; the sending device distributes the data streams with the overhead block inserted to the PCS layer; the data streams with the overhead block inserted are subjected to 64B / 66B coding according to a preset coding control word table so as to obtain a first overhead codeword specified in a FlexE protocol. Although changing the location of the FlexE Shim layer, the data processing method anddevice in the invention can execute according to a standard protocol, thereby ensuring the integrity of the PCS layer.

Description

technical field [0001] The invention relates to the communication field, in particular to a data processing method and device. Background technique [0002] The rapid increase of network traffic has increased the bandwidth of communication network information transmission. The interface bandwidth of communication equipment has been developed from 10M, 100M, 1000M, 10G, 25G, 100G to 200G / 400G. At present, a large number of 100G optical modules have been commercially used in the market, and the recently developed 200G / 400G optical modules cannot be commercialized in the short term due to their high price. In order to deliver 200G / 400G services at low cost, the international standard organization OIF has defined the FlexE protocol. [0003] The FlexE protocol can bundle multiple 100G optical modules into a large-bandwidth physical channel, such as figure 1 As shown, two 100G optical modules are bundled through the FlexE protocol to form a 200G transmission channel, which is e...
