OLT (Optical Line Terminal) agent subsystem of GPON (Gigabit-Capable Passive Optical Network) management system

Abstract

The invention relates to an OLT (Optical Line Terminal) agent subsystem of a GPON (Gigabit-Capable Passive Optical Network) management system, which comprises an SNMP (Simple Network Management Protocol) agent module, an SNMP MIB (Simple Network Management Protocol Management Information Base) module, an OMCI (ONT Management and Control Interface) slave agent module and a protocol conversion module, wherein the SNMP agent module is used for realizing communication between a network management end and OLT (Optical Line Terminal) equipment and exchanges information with an SNMP management end through an SNMP protocol; the SNMP MIB module comprises a standard SNMP MIBII and a user-defined GPON MIB and is used for describing and setting the information of the OLT equipment and the information of managed equipment; the OMCI slave agent module is used for realizing communication with ONU (Optical Network Unit) equipment and exchanges information with ONU through an OMCI frame; and the protocol conversion module is used for realizing conversion of an SNMP frame based on the SNMP protocol and the OMCI frame based on an OMCI protocol. The invention provides an OLT agent subsystem of a GPON network management system, which can lower cost and increase efficiency.

Description

technical field The present invention relates to the field of network management, in particular to an OLT (Optical Line Terminal) agent in a GPON (Gigabit-capable Passive Optical Networks) network management system using SNMP (Simple Network Management Protocol) and management It uses OMCI (ONT Management and Control Interface ONT Management Control Interface) frame to exchange information with ONU (Optical Network Unit Optical Network Unit) equipment for GPON network management. Background technique The rapid development of broadband networks and the continuous emergence of various high-bandwidth services and applications have put the introduction of broadband optical fiber access network technology on the agenda. At present, the construction of FTTH (Fiber to the Home) in North America and Japan has been launched on a large scale , and domestic FTTH experiments have already begun to be implemented in some places, and there are endless discussions in the industry on this as...
