Kind Code:
A1
Abstract:
A device for extracting an ODUflex overhead, a device for inserting an ODUflex overhead, a method for extracting an ODUflex overhead and a method for inserting an ODUflex overhead. The device for extracting an ODUflex overhead comprises: a framing module, overhead extraction modules and a whole-frame extraction module, wherein the framing module is configured to conduct a framing operation on an ODUflex service, so as to obtain ODUflex service data corresponding to the ODUflex service and frame header information, and distribute the ODUflex service data and the frame header information to a corresponding overhead extraction module according to the overhead extraction capability of each overhead extraction module; each overhead extraction module is configured to receive the ODUflex service data and frame header information distributed by the framing module, and extract overhead data of corresponding time slot data according to the acquired configuration information and the received the frame header information; and the whole-frame extraction module is configured to acquire overhead data of a plurality of pieces of time slot data extracted by the plurality of overhead extraction modules, and generate overhead data of the ODUflex service according to the overhead data of all the time slot data. The technical solution can reduce the ODUflex overhead extraction costs.
