Acquisition method and system for optical network unit capability information

Abstract

The invention relates to an optical network unit capacity information acquisition method, including the following steps: when the preset conditions are achieved, an optical network unit inquiries the own supporting capacity information in the own management information base, then the reporting information containing the capacity information which is in line with the preset format is generated andis sent to an optical line terminal; when the optical line terminal receives the reporting information, the capacity information is extracted and obtained according to the preset format. The invention also relates to an optical network unit capacity information acquisition system, including: a capacity information inquiry module, a reporting information generating module, a reporting information sending module, a reporting information receiving module and a capacity information extracting module. The invention unifies the formats of the capacity information at the both sides of ONU and OLT, which can avoid the problem that the reporting capacity information is not identified due to the un-unified formats during the equipments of the different manufacturers and ensure the EPON system to smoothly implement the corresponding OAM extension function.

Description

technical field [0001] The present invention relates to passive optical network (Passive Optical Network, referred to as PON) technology, especially a kind of ability to obtain Optical Network Unit (Optical Network Unit, referred to as ONU) under Ethernet passive optical network (Ethernet PON, referred to as EPON) Methods of information and their systems. Background technique [0002] With the rapid development of the Internet and new services and applications such as IPTV that put forward higher requirements for access bandwidth, optical fiber access has become an inevitable direction for the development of broadband access networks. Considering the maturity of technology and operating cost, EPON is the most important means of realizing optical fiber access, and it is also the access technology with the most development potential. [0003] Since the EPON system adopts a bandwidth-sharing point-to-multipoint topology, as shown in Figure 1, each Optical Line Terminal 1 (Opti...

Problems solved by technology

However, since the reporting methods set by each manufacturer may be different, it is difficult to identify the corresponding capability information between different devices, which affects the execution of the OAM function.
