A Survey of Distributed Network and Systems Management Paradigms

Since the mid 1990s, network and systems management has steadily evolved from a centralized paradigm, where all the management processing takes place in a single management station, to distributed paradigms, where management is distributed over a potentially large number of nodes. Some of these paradigms, epitomized by the SNMPv2 and CMIP protocols, have been around for several years, whereas a flurry of new ones, based on mobile code, distributed objects or intelligent agents, only recently emerged. The goal of this survey is to classify all major network and systems management paradigms known to date, in order to help network and systems administrators design a management application. In the first part of the survey, we present a simple typology, based on a single criterion: the organizational model. In this typology, all paradigms are grouped into four types: centralized paradigms, weakly distributed hierarchical paradigms, strongly distributed hierarchical paradigms and cooperative paradigms. In the second part of the survey, we gradually build an enhanced typology, based on four criteria: delegation granularity, semantic richness of the information model, degree of specification of a task, and degree of automation of management. Finally, we show how to use our typologies to select a management paradigm in a given context. KEYWORDS Distributed Network Management, Distributed Systems Management, Integrated Management, Mobile Code, Distributed Objects, Intelligent Agents, Typology.
