Although network management has always played a key role for industry, it only recently received a similar level of attention from many research communities, accelerated by funding opportunities from new initiatives, including the FP7 Program in Europe and GENI/FIND in the United States. Work is ongoing to assess the state of the art and identify the challenges for future research in the field, and this article contributes to this discussion. It presents major findings from a two-day workshop organized jointly by the IRTF/NMRG and the EMANICS Network of Excellence, at which researchers, operators, vendors, and technology developers discussed the research directions to be pursued over the next five years. The workshop identified several topic areas, including management architectures, distributed real-time monitoring, data analysis and visualization, ontologies, economic aspects of management, uncertainty and probabilistic approaches, as well as understanding the behavior of managed systems.

“…The Internet Management architecture has two main pillars: The Simple Network Management Protocol (SNMP) and a large number of MIB modules published in RFCs [5]. The latter build what, though there is no official name for it, could be called the Internet Management Model (IMM) that covers a lot of system types in its scope.…”

Abstract. According to ITIL, a CMDB (Configuration Management Database), containing a logical model of the IT infrastructure, forms the basis for effective and efficient IT Service Management. However, a common understanding of what constitutes a CMDB has not yet been established. By contrast, concepts for building and using MIBs (Management Information Base) -also aimed at providing logical models of the IT infrastructure -have long since been established in the area of systems management.This paper presents an overview of the CMDB and MIB concepts, discusses how they relate to each other and compares them based on the main purposes of a CMDB. It discusses whether modeling approaches used for MIBs can be reused for CMDBs. To this end, a criteria catalog based on core CMDB concepts and basic information requirements of ITIL's Service Management processes are derived, and the challenges of implementing a CMDB reusing concepts of common management models are discussed. Concluding, basic approaches towards integrating CMDBs and MIBs are presented.
