With the continuous progress of science and technology and the rapid development of society , metropolitan network applications and the increasing size of the Ethernet networking mode is more complex business operations , the traditional SDH (Synchronous Digital Hierarchy , Synchronous Digital Hierarchy) technology is difficult to adapt and meet a lot of new data services and the development requirements of ethernet services , a more flexible and more efficient for the IP, packet-oriented transmission network morphology, IP and transport networks to achieve the perfect combination of PTN technology follow. For the new PTN technology and Ethernet business, we need to develop new integrated network management system . In this thesis, the PTN Ethernet network management system design and implementation . MAN for the current developments , this paper briefly on PTN ( Packet Transport Network , Packet Transport Network) technology, Ethernet services and network management system's current development status were introduced. According to the software engineering ideas, in-depth study of the PTN network management system software design, and the overall hierarchy of functional design , identified PTN network management system software architecture , defined the functions of the network management system . And operation of the system hardware and software environment and the development of the tools used in the system and the key technology to do a certain degree of introduction. This article focuses on the PTN Ethernet Network Management System Design and Implementation . PTN network management system based on the overall design , combined with the demand for Ethernet services and business objects , gives the Ethernet data model and a detailed design and implementation of programs , including the client layer, business logic , south to the interface layer and data access layer these layers of design and implementation . Finally PTN Ethernet network management system functions were tested , showing good test results, and papers are summarized, and made some revisions.
