A model and evaluation of distributed network management approaches

This paper develops an analytical framework to model and compare centralized and distributed approaches for network management. Each scheme is evaluated in terms of performance and scalability for two applications, network monitoring, and data searching. The results support the intuitive argument that distributed approaches can have considerable advantages over traditional centralized network management, but a single approach may not be best for all types of applications. Instead, the most appropriate approach for a specific application should be selected after a careful evaluation. The modeling framework presented is intended to quantify the tradeoffs between different approaches to lend a basis for the selection decision
