Abstract
This paper is motivated by the increasing need for scaleable, distributed management architectures for integrated network, system and application management within the enterprise network environment.
Such integration, extension and wide area deployment of management functionality impose heavy performance requirements and produce increased management traffic. Aiming to minimize this
traffic and the overall response time, we propose a distributed hierarchical
caching scheme that attempts to take advantage of the diverse consistency requirements of
management applications. We define coherency conditions and update policies, identify the appropriate interaction semantics, and discuss an SNMP-based
implementation. In order to evaluate the proposed model and to quantify the
expected performance gains we construct a simple queuing model that provides
analytical results on the improvement of response time and the reduction of management traffic. Finally, the analysis of
experimental results provides some insight on performance improvement for specific classes of managed objects.
Keywords: integrated enterprise management, distributed management architectures, information caching, management protocols
