A management method, system and related equipment of an optical network unit

Abstract

The embodiment of the invention discloses a management method, system and related equipment of an optical network unit (ONU). The method includes: after determining that the ONU is online, generating a first instruction and a second instruction; the second instruction carries a first designated identifier representing the identity of the ONU; sending the first instruction to an optical line terminal through a first interface (OLT), the first instruction is used for the OLT to perform parameter configuration; generate a first management message according to the second instruction, and send the first management message to the ONU through a second interface; the A first management message is sent to the ONU through the OLT; the first management message carries the first designated identifier.

Description

technical field [0001] The present invention relates to the technical field of passive optical network (PON, Passive Optical Network), in particular to a management method, system and related equipment of an optical network unit. Background technique [0002] PON is a single-fiber bidirectional passive optical network characterized by point-to-multipoint, including three components: Optical Line Terminal (OLT, Optical Line Terminal), Optical Network Unit (ONU, Optical Network Unit) and Optical Distribution Network (ODN, Optical Distribution Network). OLT implements the function of optical fiber line terminal, controls ONU registration, authentication, bandwidth allocation and manages ONU. ONU, as a terminal device of ODN, has different service adaptation functions and provides users with different types and quantities of user network interfaces (UNI, User Network Interface) according to different types of ONU devices and network locations. ODN defines the uplink and downli...

Problems solved by technology

[0004] In the current PON system, ONU equipment is independently manufactured by each manufacturer. Due to the technical differences of each manufacturer, there are interoperability problems between ONU equipment and OLT, mainly including: 1. During the production process of ONU equipment, each manufacturer defines a large number of Private OMCI management entity (ME, Managed Entities), the existence of private ME makes it difficult to realize unified management and control of ONU equipment, and OLT cannot manage ONU equipment from different manufacturers; It is difficult to achieve a unified management and control scheme; 3. The OMCI protocol realizes different functions at the L2 layer, L3 layer and above by combining and associating the MEs in the ONU equipment. Due to the differences in the ONU equipment of different manufacturers, the ME combination and association of ONU equipment from various manufacturers The methods are different, and the OLT needs to adapt to various ME combinations and association methods, which increases the complexity of management and control
