Title:
METHOD, DEVICE AND SYSTEM FOR DATA PROCESSING IN ETHERNET
Document Type and Number:
WIPO Patent Application WO/2017/181675
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application is a method, related device and system for data processing. The method of the embodiments of the present application comprises: a first network device receiving PDH frame data, the first network device performing a virtual container mapping processing on the PDH frame data, loading the PDH frame data and padding bits into the virtual container so as to obtain a virtual container containing the PDH frame data; the padding bits in the virtual container carrying information of clock frequency difference between an Ethernet clock frequency and a PDH frame data clock frequency; the first network device performing virtual container end-to-end pseudo-line simulation PWE3 encapsulation for the virtual container so as to obtain a virtual container PWE3 message. The embodiments of the present application may lower the difficulty of clock frequency recovery when the PDH frame data are transmitted in an Ethernet, reduce clock frequency jitter and drift caused by clock frequency recovery, and improve the user experience.
