Cross-device and cross-protocol EPON element management system

Abstract

The invention discloses a cross-device and cross-protocol EPON element management system. The system achieves the uniform monitoring and management on the heterogeneous EPON; an EPON element metadata model is provided, and uniform description of heterogeneous EPON devices, interfaces and protocols is achieved; a parallel polling method for the network element performance and state in the distributed type EPON is provided, and rapid and efficient query of the performance and the network element state of the large-scale distributed type EPON is achieved; a uniform configuration system of the heterogeneous EPON devices is built, and uniform configuration of different devices and different northbound interface protocols is achieved; a network element state displaying system in the large-scale distributed type EPON is built, and uniform and real-time display of the heterogeneous EPON is achieved. The UML is adopted in the EPON element metadata model, so that the processes such as cataloguing, registering and finding of the EPON resources are accurately, clearly and conveniently achieved, interconnection, intercommunication and interoperability of the heterogeneous EPON system are achieved conveniently, the comprehensive management capacity of the EPON is improved, and long-term interests are brought to the EPON management.

Description

technical field [0001] The invention belongs to the field of optical fiber communication, and in particular relates to a network element management system in a cross-device and cross-protocol EPON network. Background technique [0002] With the rapid development of Internet services and the continuous emergence of various new services, people's demand for network bandwidth has increased significantly. Traditional wired access networks such as coaxial cables and copper wires have limited bandwidth and cannot meet the growing transmission data. volume requirements. Ethernet Passive Optical Network (EPON, Ethernet PON), developed based on Ethernet (Ethernet) and PON (passive optical network) technology, its bandwidth is dozens of times that of traditional Ethernet, and its implementation cost is continuously reduced. It uses passive optical Network transmission, providing multiple services on top of Ethernet, will be an important technical means for broadband multi-service int...

Problems solved by technology

The comprehensive management method for individual models is simple to implement. However, EPON network application and management groups, such as China Telecom and State Grid, face heterogeneous devices and heterogeneous protocols when performing device configuration, device operation status query, and network status query At the same time, the device and network status query must be completed through the interface protocol and user interface (GUI: graphic user interface) provided by the manufacturer; what is more serious is that the enterprise group is performing device evaluation, network performance evaluation, network storm prevention, During network maintenance, etc., heterogeneity hinders the operation of comprehensive management, causing conflicts between equipment suppli
