MESIS: Resource and Service Management (1)
Management Environment for Secure and Interoperable Services
MESIS provides tools
with the typical features of traditional management environments.
They include the monitoring of the state of the distributed
system, the possibility to control and coordinate replicated
resources, the dynamic installation and configuration of
new network resources, and the optimized access to replicated
information by taking into account both current traffic level
and query locality.
MESIS has demonstrated to be suitable to implement tools for monitoring and controlling network resources, but the MESIS main goal is to manage complex network services, even obtained by tailoring and composing existing ones, and to dynamically introduce new services in the existing infrastructure without suspending operations.
In the area of mobile computing, for example, we have tested MESIS usability for the design, the implementation and the management of a Personal Communication Support (PCS) service that answers the requirements of the Virtual Home Environment concept described by UMTS and FPLMTS/IMT-2000.
We have also realized a MESIS Video on Demand (VoD) service, based on a set of mobile lower-level services, implemented by agents that are distributed over the paths between the source and the targets of the video stream. MESIS VoD permits users to require a QoS level for any multimedia stream, and allows to manage and adjust the requested quality during service provision, to respond to dynamic modifications of network resource availability.
