Abstract: A data transmission method includes an optical line terminal (OLT) for obtaining a data template. The OLT then obtains corresponding optical network terminal (ONT) data based on one or more data types defined in the data template. The OLT then encodes the ONT data according to an external data representation (XDR) format and sends encoded ONT data to a management server. Further, the management server stores and manages the ONT data. The OLT collects the corresponding ONT data based on the data template, encodes and reports the ONT data according to the uniform XDR format. The embodiments define a unified statistics collecting and reporting manner of ONT data and uses standardly defined ONT data to help the management server store and manage the ONT data.

Abstract: The present invention discloses a method for maintaining quality of service QoS, which includes: identifying a CLP and a service type of a newly received ATM cell, and obtaining a corresponding QoS label; when the QoS label corresponding to the newly received ATM cell is different from a QoS label corresponding to a buffered ATM cell, encapsulating the buffered ATM cell into a pseudo wire PW packet in a concatenation manner and sending the pseudo wire PW packet, where the QoS label corresponding to the buffered ATM cell is used as a QoS label of a PSN transport header of the PW packet, or is used as QoS labels of both the PSN transport header and a PW header of the PW packet, and buffering the newly received ATM cell. The present invention further provides a corresponding provider edge PE device and a corresponding ATM PWE3 system.
