On the design and implementation of a hierarchical, generic and scalable open architecture for the network management layer
Filip De Turck, Filip Vandermeulen, Piet M. A. Demeester · 2002
In this paper we address the design and implementation aspects of a generic architecture for the NML (network management layer). The focus in this paper will be on SNMP manageable ADSL/ATM networks. SNMP (simple network management protocol) is a standardized protocol which is supported by almost all current computer network devices. The architecture is compliant with the TINA (Telecommunication Information Network Architecture) recommendations and is implemented based on the CORBA (Common Object Request Broker Architecture) standard. During the design and implementation process, a lot of effort has been devoted to the performance, robustness, persistence and consistence of the distributed software under various load and fault scenarios. The most suitable distributed software techniques, like object transactions, concurrency control, event notification and naming service were used and thoroughly tested on their usability. It is also indicated how the core of the described architecture can be extended towards next-generation IP-based networks.
