Problems solved by technology

[0013] The technical problem to be solved by the present invention is to overcome the low accuracy of service recovery in the GPON system in the prior art, the configuration recovery cannot be performed after negotiation with other sublayers, the communication mechanism is complicated, and the service recovery function does not support, which will lead to repeated configuration and thus increase The defects of ONU start-up time and occupation of OLT system resources provide a service recovery method and system in GPON with high accuracy and will not cause repeated configuration

Embodiment Construction

[0046] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0047] refer to figure 1 , the business recovery method in the GPON of the present invention, this GPON comprises ONU, OLT and passive optical distribution network, the business recovery method in this GPON comprises the following steps:

[0048] Step S 1 , read the MIB in the local database of this ONU, and judge the kind of MIB, if this MIB is created locally, then enter step S 2 ; If the MIB is created by the OLT, go to step S 3 ; If the MIB is "ExtendedVlanTaggingOperationConfigurationData and MulticastOperationsProfile", that is, "extended VLAN tagging operation configuration data" or "multicast operation" attribute, then enter step S 6 ;

[0049] Step S 2 , Save the MIB item by item to the corresponding MIB global variable, and then enter step S 7 ;

[0050] Step S 3 , judg...

Abstract

The invention discloses a service restoration method in a Gigabit Passive Optical Network (GPON). The service restoration method includes: S1 judging the variety of Management Information Banks (MIBs), and entering S2 if the MIBs are built locally, or entering S3 if the MIBs are built by an Optical Line Terminal (OLT), or entering S6 if the MIBs are extended Virtual Local Area Network (VLAN) marked operation configuration data or have multicast operational attributes; S2 storing the MIBs to MIB global variables; S3 judging whether to restore the MIBs in the message creating or arrangement format, entering S4 if the MIBs are restored in the message creating format, or entering S5 if the MIBs are restored in the message arrangement format; S4 restoring the MIBs in the message creating format; S5 restoring the MIBs in the message arrangement format; S6 updating the global variables one by one circularly and performing arrangement restoration; S7 updating logic code values of the MIB global variables in a database. The invention further discloses a service restoration system in the GPON. The service restoration method and system improve data restoration accuracy and avoid data loss.

Description

technical field [0001] The present invention relates to a service recovery method and system in GPON (Gbit Passive Optical Network), in particular to an automatic recovery OLT (Optical Line Terminal, optical line terminal, terminal equipment used to connect to optical fiber trunk lines) A service restoration method and system in a GPON of a service. 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. Because of its many advantages such as high bandwidth, high efficiency, large coverage and rich user interfaces, It is regarded by most operators as an ideal technology to achieve broadband and comprehensive transformation of access network services. [0003] Like all PON (Passive Optical Network, Passive Optical Network) systems, GPON consists of ONU (Optical Network Unit, Optical Network Unit), OLT and passive optical distribution network. The OLT...
