AI Technical Summary

Technical Problem

The fill code block insertion method defined by the existing FlexE standard is difficult to apply to higher-speed PHY interfaces such as 800GE and 1.6TE, and the detection method has poor fault tolerance.

Method used

N consecutive padding code blocks are periodically inserted in the data stream, n is an integer greater than or equal to 4, suitable for the 800GE and 1.6TE PHY interfaces, and the padding sequence is searched in a soft decision manner to improve fault tolerance.

Benefits of technology

The filling code block insertion method applicable to higher-speed PHY interfaces is implemented, and the fault tolerance and success rate of filling sequence detection in the data stream is improved.

Abstract

The invention discloses a data processing method and device and belongs to the technical field of communication. The method is applied to the flexible Ethernet (FlexE), and the method is applied to the flexible Ethernet (FlexE). The method comprises: receiving an initial data stream sent by a FlexE instance, periodically inserting a filling sequence in the initial data stream to obtain a first data stream, the first data stream comprising the periodically appearing filling sequence, the filling sequence comprising continuous n filling code blocks, and n being an integer greater than or equal to 4. The invention provides a FlexE (FlexE)-oriented method capable of inserting more filling code blocks into a data stream, which can be suitable for PHY (Physical Layer) interfaces with higher rate, such as a 800 gigabit Ethernet (GE) PHY interface, a 1.6 TE PHY interface and the like, and can adapt to the evolution of the Ethernet standard.
