Problems solved by technology

[0003] Aiming at the problem that the existing optical network terminal receives OMCI may not be a complete business model, and there are ambiguous errors that cause the optical network terminal to enter an error state, a method for delivering clear logical service flows is now provided. The driver layer directly ignores ambiguous business flows to realize optical network terminals that prevent optical network terminals from entering an error state and a method for detecting ambiguity of logical service flows

Abstract

The invention discloses an optical network terminal (ONT) and a method for detecting logical service flow ambiguity. The ONT is applied to a gigabit-capable PON. The ONT comprises a receiving unit, a transmitting unit and a detection unit, wherein the receiving unit is used for receiving an optical network unit (ONU) management control interface protocol management message sent by an optical line terminal; the transmitting unit is used for generating a response message according to the ONU management control interface protocol management message, and sending the response message to the optical line terminal; and the detection unit is used for extracting all logical service flows in the ONU management control interface protocol management message, acquiring integral logical service flows with a unique data packet flow direction, and outputting the logical service flows. According to the ONT, all logical service flows in the ONU management control interface protocol management message are extracted through the detection unit in order to judge the integrity of the logical service flows and the presence of ambiguity, error logical service flows are ignored, and the ONT is prevented from entering an unpredictable error state, so that correct logical service flows become valid on a driving layer of the ONU.

Description

technical field [0001] The invention relates to the communication field, in particular to an optical network terminal and a method for detecting the ambiguity of a logical service flow. Background technique [0002] The access technology of the passive optical access system (Gigabit-Capable PON, GPON) is an access network technology of the passive optical network (Passive Optical Network, PON) technology, which provides a downstream bandwidth of 2.5Gbps and an upstream bandwidth of 1.25Gbps , data service configuration has very strong flexibility, the existing GPON protocol is an optical network unit management control interface protocol for information exchange between optical line terminal (Optical line terminal, OLT) and optical network terminal (Optical network terminal, ONT) (ONU Management and Control Interface, OMCI) technical solution simply solves the problem of adaptation between the OMCI logic service layer and the underlying chip driver of the ONT. In the GPON a...
