Abstract

Abstract Passive Optical Network (PON) plays an important role in optical access network due to its characteristics of resources saving and network protocol transparency. In the process of running and operating a PON system, a reliable network management system (NMS) is necessary. In order to acquisition the management object, NMS should perform topology automatic discovery process with the help of embedded software. Aiming at various types of the convergence network’s topology and the complicated architecture, this article proposes a topology automatic discovery algorithm to promote the network management. We have designed and verified the automatic discovery method on our simulation platform with SNMP-Agent-enabled OLTs.
