Method for automatically discovering coaxial broadband access head terminal, management method and management system

Abstract

The invention provides a method for automatically discovering a coaxial broadband access head terminal, a method and a system for managing Ethernet over coax (EOC) terminal equipment. The method comprises the following steps: a first message carrying the basic information of the coaxial broadband access head terminal is multicast by the coaxial broadband access head terminal; and the coaxial broadband access head terminal is discovered after the first message is captured by an optical network unit (ONU); the automatic discovery of the EOC head end equipment can be finished by an optical line terminal (OLT) and network management according to the condition in no need of preconfiguring the equipment IP and the network management IP address; and the network overall topology structure of PON (passive optical network)+EOC can be dynamically displayed to finish the configuration and the management of the EOC head end and the EOC terminal, thus obviously lowering the complexity of PON+EOC network management, engineering starting and maintenance.

Description

technical field [0001] The present invention relates to the field of optical and coaxial hybrid access network (PON+EOC), in particular to a method for automatically discovering a coaxial broadband access head terminal, a method and a system for managing EOC terminal equipment. Background technique [0002] With the rapidly growing demand for converged services in the information society, the construction of broadband access networks has become a bottleneck in providing converged services. In view of the huge cost required for the construction of the access network, the integration and transformation of existing network resources and the rapid and low-cost provision of converged services have become the focus of current triple play research. One of the important solutions is based on optical and coaxial hybrid access network technology. [0003] PON (Passive Optical Network, Passive Optical Network) is a point-to-multipoint optical network, its structure is as follows figu...

Problems solved by technology

[0010] 1) It is necessary to pre-configure initialization parameters on the EOC head-end equipment in a local out-of-band manner, which increases the tight coupling and complexity of the service activation process between various departments of the operator, and increases the management cost of the operation and maintenance department in the later stage

[0011] 2) The management information between the PON and EOC networks is isolated, and the network management cannot uniformly display the overall topology structure of the access network and the connection relationship between ports, which increases the difficulty of network management for the network management and operation and maintenance departments

[0015] 1) It is necessary to pre-configure initialization parameters on the EOC head-end equipment in a local out-of-band manner, which increases the tight coupling and complexity of the service activation process between various departments of the operator, and increases the management cost of the operation and maintenance department in the later stage

[0016] 2) The EOC head end sends its own initial information to the OLT in the form of a broadcast message, and the OLT generally sets a rate limit for the uplink broadcast message. Therefore, the message may be discarded, resulting in a longer discovery process by the EOC head end; In addition, the OLT needs to detect the broadcast packets one by one, which greatly increases the processing burden of the OLT and makes the OLT have reliability risks.

[0017] 3) Technically not all OLTs support the analysis of uplink broadcast messages, therefore, this management method does not have universal significance
