Embodiment Construction

[0039] 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:

[0040] 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.

[0041] 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:

[0042] A. The CTC state machine is the core of the technical solution and is responsible for handling all events and scheduling.

[0043] 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 invention provides a method and a device for realizing CTC protocol stack of EPON terminals. The device comprises a CTC state machine, a CTC function module and a concrete-proposal CTC function module, wherein the CTC state machine is in charge of processing all events and dispatch; the CTC function module is in charge of calling local data storage, saving configuration and calling proposal-related CTC protocols; the concrete-proposal CTC function module provides event access and an implementation interface for concrete commands; and the CTC function module sets the event access and the implementation interface separately. Mutual independence among interfaces and simple logical relationship provide design convenience for supporting different hardware and enable the protocol stack to have foreseeable robustness and be easy to be compatible with EPON equipment of different manufacturers. In addition, the invention adopts state-machine technology to process management-type application, thereby having considerable adaptability and avoiding the situation that the complex competitive condition protection and the like of unnecessary concurrency requirements are easy to have Bug.

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: [0004] In the figure, the OLT is the central e...
