Embodiment Construction

[0062] see figure 1 and figure 2 As shown, the embodiment of the present invention provides a configuration management method of parallel OAM in an EPON system, comprising the following steps:

[0063] S1, OLT, according to the configuration data, create n processes that need to carry out service configuration to the ONU, n is a positive integer, n is the parallel coefficient of the EPON system, n=the number of OAM physical channels in the EPON system=the number of PON ports of the OLT, The OLT specifies a configuration domain for each process, and each configuration domain includes several ONUs; in order to realize the mutual cooperation of multiple processes, the ONUs in each configuration domain are divided into several groups, for example: a configuration domain contains a ONUs, a is a positive integer, a=maximum ONU splitting ratio, all ONUs in the configuration domain are divided into b groups, each group contains a / b ONUs.

[0064] S2. The OLT uses a parallel process...

Abstract

The invention discloses a parallel OAM configuration management method in an EPON system and a system thereof and relates to the OAM technology field in the EPON system. The system comprises an OLT and an ONU. The OLT comprises one configuration module, n first determination modules and n second determination modules. The method comprises the following steps that the OLT creates n processes which need to carry out service configuration on the ONU and assigns one configuration domain for each process; the OLT controls parallel work of all the processes; each process loops through the ONU in the corresponding configuration domain and the ONU to be configured is configured; when the number of times for one process which does not find the ONU to be configured continuously in the corresponding configuration domain is m, the process loops through other groups which are not looped through, configures the ONU to be configured and then loops through the ONU in the corresponding configuration domain again. In the invention, a parallel mechanism is introduced, configuration issuing efficiency of an OAM channel can be increased and ONU service configuration time is shortened.

Description

technical field [0001] The present invention relates to the technical field of OAM (Operation, Administration and Maintenance) in an EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) system, in particular to a configuration management method and system for parallel OAM in an EPON system. Background technique [0002] EPON integrates common Ethernet technology and cheap passive optical components, and is a new type of optical fiber access network technology with low cost and high capacity. EPON adopts a point-to-multipoint structure and is transmitted through passive optical fibers, and can support multiple services such as data, voice and video at the same time. A typical EPON system consists of OLT (OpticalLineTerminal, Optical Line Terminal), ONU (OpticalNetworkUnit, Optical Network Unit) and ODN (OpticalDistributedNetwork, Optical Distribution Network). OLT is deployed in the central computer room and provides optical fiber interfaces for passive ...
