Design of Element Management System for EPON

摘要

Element Management System (EMS) is a system to manage network element (NE) for Ethernet Passive Optical Network (EPON). This allows the user to manage all the features of each network element (NE) individually. Network element (NE) exposes one or more management interfaces that the EMS uses to communicate with and to manage them. EMS has been design to fulfill FCAPS criteria which consist of fault management, configuration management, accounting management, performance management and security management. EPON is an emerging access network technology that provides a low-cost method of deploying optical access lines between a carrier's central office and a customer site. EPON build on the International Telecommunications Union (ITU) standard G.983 for asynchronous transfer mode PON (APON) and seek to bring to life the dream of a full-services access network (FSAN) that delivers converged data, video, and voice over a single optical access system.
