Optical network unit, method for dynamic extension management function thereof and GPON system

Abstract

The invention discloses an optical network unit, a network unit and a method for dynamic extension management function of the optical network unit and a GPON system. An optical line terminal sends a data packet formed by a dynamic depot file corresponding to a to-be-updated management entity to the optical network unit through a standard upgrading interface in an OMCI protocol; the optical network unit determines whether the received data packet is formed by the dynamic depot file corresponding to the to-be-updated management entity according to fields included in a head of the data packet; and if yes, loading the to-be-updated management entity according to the dynamic depot file included in the data packet. For the to-be-updated management entity, updating data corresponding to the to-be-updated management entity is sent in a form of the dynamic depot file, so that dynamic loading is carried out on the to-be-updated management entity, and other businesses of the ONU cannot be interrupted; and furthermore, the loaded file is small, the loading time is short and the whole process does not need Flash operation, so that a condition of damage to equipment due to the Flash operation can be avoided.

Description

technical field [0001] The invention relates to the technical field of GPON, in particular to a network unit, a method for dynamically expanding its management function and a GPON system. Background technique [0002] GPON (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Most operators regard it as an ideal technology to achieve broadband and comprehensive transformation of access network services. In the GPON system, the management information base (MIB, Management Information Base, MIB) is represented by the managed entity (Managed Entity, ME). The so-called managed entity refers to the resources or services of the Optical Network Unit (ONU). abstract. When the Optical Line Terminal (OLT) remotely manages the ONU through the OMCI protocol, it will perform operations such...

Problems solved by technology

[0004] In view of this, the embodiment of the present invention provides a network unit, a method for dynamically expanding its management function, and a GPON system to solve the problem caused by the fact that the MIB of the existing ONU does not have a dynamic expansion function.
