Abstract

The invention discloses an optical broadband access network service resource tree topology discovery algorithm, belongs to the technical field of an optical broadband access network and relates to network topology discovery algorithm realization based on an MAC address forwarding principle, a network link splicing method for optical network devices OLT and ONU, and correlation matching between client service and a network topology. The algorithm comprises four steps of collecting basic data; splicing network physical links; splicing service and the links and forming a service resource tree topology. The optical broadband access network service resource tree topology discovery algorithm provided by the invention has the advantages that the timeliness performance is provided, the maintenancecost is low and the accuracy is high, and an optical broadband access network fault can be discovered and positioned accurately in real time.

Description

Technical field: [0001] The present invention relates to the technical field of optical broadband access network, in particular to an optical broadband access network service resource tree topology with good real-time performance, low maintenance cost and high accuracy, which can accurately and real-time discover and locate optical broadband network faults Discovery algorithms. Background technique: [0002] With the development of optical broadband network technology, the scale of the network becomes larger and the structure becomes more and more complex, but many network management tools only provide topology discovery at the network layer. The main element of the network layer is the router. Because the router has the learning ability, it can grasp the routing distribution information in the entire network in time, so as to realize the function of automatic routing in the network. Therefore, the topology structure can be obtained by obtaining and analyzing the routing tab...
