1 in VIOLA T-Systems are responsible for operational procedures and network management within the VIOLA consortium. VIOLA is a test bed for network approaches as well as a platform for application tests. One of the design goals of operational procedures is to minimize dependencies between application and network layers. Therefore coordination between application users, network test staff and T-Systems SMC (System Management Centre) is required. SMC is operating the VIOLA network in close contact with users, fibre providers and equipment manufacturers. The SMC is focussing on Incident Management, Configuration Management, Maintenances, Network Changes, Release Management and SLA-Management. The VIOLA network is complex and heterogeneous. The VIOLA transmission paths are based on lambdas from Deutsche Telekom and several fibre providers. Network equipment is provided by ADVA and Alcatel for WDM, Alcatel and Siemens for SDH, Alcatel and Riverstone for Ethernet switches. T-Systems SMC operates five different management systems as each manufacturer contributes one or more. In-band management is difficult in such a heterogeneous environment. Furthermore VIOLA is supposed to change its topology in the next years. Therefore T-Systems have set up an outband management with IP-Sec- and GRE- tunnelling over the existing G-WiN. The network management will be in cooperation with FhG, University of Bonn and Forschungszentrum Jülich while network tests are running.
