A Simple Typology of Distributed Network Management Paradigms

Over the past few years, network management has steadily evolved from a centralized model, where all the management processing takes place on a single network management station, to distributed models, where management is distributed over a number, potentially large, of nodes. Among distributed models, one, epitomized by the SNMPv2 and CMIP protocols, has been around for several years, whereas a flurry of new ones, based on mobile code, distributed objects or cooperative agents, have only recently emerged. This paper reviews all major network management paradigms known to date, and proposes a simple typology to classify them.
