Ethernet over coax (EOC) equipment self-discovery and self-configuration method based on Ethernet passive optical network (EPON) and EOC technology for integrated network management

Abstract

The invention discloses an Ethernet over coax (EOC) equipment self-discovery and self-configuration method based on an Ethernet passive optical network (EPON) and EOC technology for integrated network management. The EOC equipment self-discovery and self-configuration method comprises the steps that (S10) EOC equipment reports information and a connection relationship between the EOC equipment and an EPON system to an integrated network management system through an optical line terminal (OLT) of the EPON system; (S20) the integrated network management system issues basic configurations; (S30) the integrated network management system polls intercommunication management items and then issues configurations; (S40) the integrated network management system issues service configurations. According to the EOC equipment self-discovery and self-configuration method, the situation that an optical network unit (ONU) is topologically connected with the EOC equipment only in a manual manner for construction in the prior art is changed, and the network maintenance and management efficiency is improved.

Description

technical field [0001] The invention relates to the field of integration of three networks, in particular to an EOC device self-discovery and self-configuration technology based on integrated network management of EPON+EOC technology. Background technique [0002] The transformation scheme based on EPON (Ethernet Passive Optical Network) is the most suitable and widely used technical scheme for radio and television operators. EPON is a passive optical network access technology based on Ethernet, which has the remarkable characteristics of high bandwidth, long distance and high optical splitting. Because the topological structure of the EPON network is similar to the branch line of the existing HFC network, it is very easy to superimpose EPON on the basis of the current HFC network. As long as the OLT is placed at the sub-head end and the ONU is placed at the original optical node, the superposition of HFC and EPON can be completed and the bidirectional network can be realiz...

Problems solved by technology

[0003] Due to the network topology of the EPON+EOC system, the OLT can automatically discover the ONU, and the ONU can also actively report its own information to the OLT. EOC equipment, but the link between ONU and EOC equipment can only be maintained and managed manually

Since Shaanxi Radio and Television adopts the FTTB access method, there are a large number of ONUs and EOCs. In the process of large-scale network construction and deployment, the disadvantages of manual configuration and maintenance waste of resources, low efficiency, and high error rate are very significant.

[0004] In the integrated network management system based on EPON+EOC technology, the EPON system and the EOC system are respectively managed and parameterized through the SNMP protocol, but the network topology of the EPON+EOC system can only be maintained and managed manually. In the process of large-scale network deployment, due to the large number of EOC devices, manual methods cannot effectively maintain and manage the network
