Topology discovery method, device and system of broadcast television network equipment

Abstract

The invention belongs to the field of a broadcast television network, in particular to a topology discovery method, device and system of broadcast television network equipment. The topology discovery method comprises the following steps of: sending an authentication package through broadcast by the first level equipment; receiving the authentication package sent by (N-1)th level equipment connected with the Nth level equipment by Nth level equipment, and judging whether the (N+1)th level equipment connected with the Nth level equipment is provided below the Nth level equipment, wherein N is more than or equal to 2; if so, sending a confirmation package to the (N-1)th level equipment by the Nth level equipment and sending the authentication package which is added with own information through the broadcast; otherwise, adding own relative information into the authentication package by the Nth level equipment, changing the information type of the authentication package into a feedback package, and sending the feedback package to the primary equipment directly; and analyzing by the first level equipment according to the received feedback package and generating a topological relation list of all the equipment. By adopting the invention, the network equipment topology relation list is accurately and timely generated, so that a plurality of different types of the equipment can be combined well; and the uniform management and control is realized.

Description

technical field [0001] The invention belongs to the field of radio and television networks, in particular to a method, device and system for discovering the topology of radio and television network equipment. Background technique [0002] With the continuous deepening of triple play, the EPON (Ethernet Passive Optical Network) equipment and EoC (Ethernet data transmitted through coaxial cable) equipment used in the radio and television system have greatly increased. Broadband transmission platform combined with axial cable distribution network) equipment and digital set-top boxes are all in the radio and television network. These different types of equipment constitute a huge system with a large number of equipment. [0003] At present, equipment management belongs to several systems, such as EPON equipment, EoC equipment, HFC equipment and set-top box are each a management system, which increases the management cost and management difficulty to a certain extent. If these t...
