Um sistema de operações para suporte à gerência de centrais digitais heterogêneas baseado em SNMP.

Abstract

The evolution of the current telecommunications systems has created an environment composed of heterogeneous networks and equipments, with a plethora of services and an increasing number of users. Management of such a complex network is fundamental to deliver the quality of service and profit the telecommunications business demands. One of the main goals of the telecommunications business is to maximize the plant productivity and optimize the use of available resources. The multi-vendor characteristic of most telecommunication plants makes it difficult to adopt a TMN approach as a primary paradigm. Intermediate solutions have been searched as options to provide certain functions of management to equipment from different vendors. The project which is the subject of this dissertation presents a cost effective solution to implement the performance management of a heterogeneous telephonic network. It is a software system that monitors the traffic and utilization rate of a previously defined set of central offices (switches), e.g, NEAX 61 BR, produced by NEC, Tropico-RA and Tropico- R, produced by CPqD, in order to determine the global efficiency of the network. The system has been implemented and deployed in Telemar-Paraiba, former Telpa, as an operations system which is part of the TMN development effort of the company.
