On the design of an integrated management platform for an ADSL/ATM based access network using CORBA

In this paper, we address the problem of the end-to-end management of a heterogeneous public network. In the case study, the access part of the network is based on the ADSL technology for the provisioning of high-speed IP over ATM to the customer and consists of ADSL network elements and ATM access switches. The core of the network is ATM-based and provides connectivity to retailers, which in this case are Internet service providers (ISP). We give an insight into the technological approach which consists of building a distributed platform, based on CORBA, that integrates existing element and network management systems and provides an end-to-end configuration, performance and fault management solution. The architecture of a generic resource adapter for SNMP devices as well as an automated SNMP-to-IDL mapping method are detailed
