Embodiment Construction

[0038] see figure 2 , in the device of the EPON terminal CTC protocol stack, it is divided into two parts from left to right. Their meaning is:

[0039] 1) The CTC abstract model is the focus of this implementation method. It is the core of the CTC protocol stack. It performs unified processing and scheduling of all events in the CTC protocol stack, and analyzes and responds to the protocols specified by the CTC protocol stack.

[0040] The CTC abstract model (module) is at the central position, and all events will be sent to this module for unified processing and dispatched by this module; this module contains two sub-modules, and their meanings are as follows:

[0041] A. The CTC state machine is the core of the technical solution and is responsible for handling all events and scheduling.

[0042] B. CTC function model (module), which decomposes and implements specific functions (operations) specified by the CTC protocol stack. It calls the local data storage function to...

Abstract

The present invention is a method and device for realizing the CTC protocol stack of an EPON terminal. The device includes a CTC state machine, a CTC function module, and a specific scheme CTC function module. The CTC state machine is responsible for processing all events and scheduling, and the CTC function module is responsible for calling the local Data storage, save configuration, call scheme-related CTC protocol; specific scheme CTC function module provides event entry and implementation interface of specific commands, and CTC function module independently sets event entry and implementation interface. The interfaces are independent of each other, and the logical relationship is simple, which provides convenience for design to support different hardware, makes the protocol stack predictable and robust, and is easy to be compatible with EPON equipment from different manufacturers. Moreover, the present invention adopts the state machine technology to process management applications, which has considerable adaptability, and avoids situations such as complex competition condition protection of unnecessary concurrent requirements, which are extremely prone to bugs.

Description

technical field [0001] The present invention relates to optical communication equipment and methods, more precisely, it is a realization method and device compatible with multiple CTC protocol stacks. Background technique [0002] Applied to the terminal equipment (ONU for short) of the Ethernet-based passive optical network (EPON for short), to meet the needs of equipment intercommunication and remote management of different manufacturers. This type of equipment is currently mainly used in access networks, and the networking method is FTTX, including: fiber-to-the-home FTTH, fiber-to-the-building FTTB, etc. A single ONU can provide bidirectional bandwidth up to 1GB. It is also widely used in other scenarios that require high bandwidth and latency, such as video / security monitoring on urban roads. [0003] Such as figure 1 Shown is a typical application scenario, that is, the application scenario of fiber-to-the-home FTTH. In the figure, the OLT is the central office devi...
