An Adaptive Resource Management Architecture for Global Distributed Computing

309 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1998.In this thesis, we present a new paradigm for developing safe, customizable middleware for the global information infrastructure. The composition of multiple resource management services is necessary to guarantee safe, cost-effective QoS in such an infrastructure, which by its very nature is open and distributed. We specify core resource management services---remote creation, distributed snapshot and directory services that can be used as a basis for more complex activities. The thesis develops mathematical frameworks and formal mechanisms for reasoning about the interaction and composition of resource management activities in open distributed systems, their dynamic installation and modification. In particular, we develop a two-level meta-architectural model of distributed computation based on actors. This enables us to consider separately issues such as: functional behavior of an application; and resource management issues such as storage management, load balancing, QoS specification and enforcement. The utility of this approach is illustrated by developing QoS based resource management techniques for distributed multimedia systems and reasoning about them.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
