Resumo(s)
In the context of the MSc in Computer Engineering, I have worked as a Software Developer in the TNMS (Telecommunication Network Management System) project at Nokia Siemens Networks, a company that develops products and services for fixed, mobile and enterprise networks. TNMS is a software system designed for configuration and management of a telecommunications network and has several modules developed by different teams. I was selected to work in the team led by Paulo Sergio Santos. Network management plays a key role in the telecommunications industry. The network infrastructure has been considerably improved over the last two decades to provide more bandwidth needed to satisfy the increasing demand for network services. However, to make the network usable a Network Management System (NMS) like TNMS has to be developed. NMS functionality covers the following areas: Network Management, Service Management, Fault Management and Performance Management. Network Management allows the user to configure the network topology. Service Management allows the user to create a network service on behalf of a subscriber. Fault Management deals with the occurrence of failures in the network. Performance Management deals with the measurement of network parameters to let the user evaluate the transmission quality and resource usage. My work focused on developing the version 11 of TNMS. Under TNMSv11, I had to implement the feature Basic Support of ASON for SDH VC-4. ASON (Automatically Switched Optical Network) is a ITU-T (International Telecommunication Union - Telecommunication Standardization Sector) network model which defines how the NMS should carry the network management functions. Basic Support of ASON for SDH VC-4 is the first ASON feature to be included in TNMS.
