Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0038] The basic idea of ​​the present invention is: flow classification is carried out on the service flow received from the user side on the ONT, and the control message and the data message are marked with different GEM Port-IDs for transmission separately, and the control message and the data message are transmitted separately during the transmission process. Packets are processed with high priority.

[0039] Wherein, the high-priority processing of the control message in the transmission process can be the high-priority processing of the control message on the ONT, or the high-priority processing of the control message on the OLT, Alternatively, high-priority processing of the control message may also be performed on the ONT and the OLT at the same...

Abstract

The invention discloses a transmitting method of upward control report in the Jupiter passive optical network system, which is characterized by the following: the optical network terminal (ONT) transmits the business flow of the user to the optical line terminal (OLT), which classifies the business flow on the ONT; the control report and data report is punched by GEM Port-Ids to be transported separately, which have high precedence of the control report to process in the transmitting course. The invention makes the control report transported timely, which ensures the service quality of control report.

Description

technical field [0001] The present invention relates to optical access technology, in particular to a method for transmitting uplink control messages in a Giga-bit Passive Optical Network (GPON) system. Background technique [0002] Current broadband access technologies are mainly divided into copper wire access technologies and optical access technologies, wherein an access network implemented by the optical access technology is called an Optical Access Network (OAN). An implementation technology of an optical access network is a passive optical network (Passive Optical Network, PON) technology, which is an optical access technology for point-to-multipoint transmission. [0003] Referring to the PON system structure shown in FIG. 1 , the PON system mainly includes three parts: an Optical Line Terminator (OLT), an Optical Distribution Network (ODN) and an Optical Network Unit (ONU). Among them, the OLT is used to provide the network side interface (SNI) for the OAN, and con...
