The Research And Implementation Of SNMP Network Administration In EPON

EPON(Ethernet Passive Optical Network) is a relative new connecting mothodology for optical network.Contrasting with traditional connecting method, it has outstanding advantages as broad band, high security and low cost. More and more countries are deploying and going to deploy EPON. EPON has also become a very import LAN connecting method due to its natural born superiorities.Network administration is part of EPON which can't be missed, constructed based on SNMP(Simple Network Management Protocol), adopting standard ASN.1 grammar. It manages all sorts of devices affiliated to EPON in a uniform means,also responsible for running and maintaining the whole EPON in the same time. Network administration supplies the network administrators and users with a high effective technology for supervising and managing EPON as well as guaranteeing that EPON functions properly though under a situation of massive network business data flow.This dissertation begins with some essential knowledge of EPON system, then proceeds with the software architecture, introduces the hierarchy, function and working principle of network administrating software in the integrated EPON. How the SNMP and ASN.1 operate to affect the design are also discussed in detail. It also includes the outline step of designing process, developing envrironment, deployment of practical tools, concretely implementing process. In the design part, I explain functions and desiging thoughts of each single software module and propose a method to implement a sort of network administration using SNMP within EPON which has been analyzed the feasibility. In the implementation part, I give a specific analysis to the key important source codes, especially the disposal of multi-specification ONU whose function is added after the integral design by reason of its complexity. The immediate following component is the discussion of visual web network administration. As the conclusion I report how the software behaves in the practical enviroment and all bugs which have been detected and fixed, also a review of the entire designing process.
