Policies are derived from management goals and define the desired behavior of distributed heterogeneous systems, applications, and networks. To apply and deal with this idea, a number of concepts have been defined. Numerous policy definitions, policy hierarchies and policy models have evolved which are all very different, as they were developed from diverse points of view and without a common p...

Middleboxes are commonly deployed to implement policies (e.g., shaping, transcoding, etc.) governing traffic traversing ISPs. While middleboxes may be used for network management to limit the impact of bandwidth-intensive applications, they may also be applied opaquely to limit access to (or degrade) services that compete with those offered by the network provider. Without regulation or account...

The theme of this extended abstract is that, while the need for dependable computing has been around for a long time, there is a separate but related area, system safety, which has already had to tackle the problem of dependability seriously and explicitly. There is a lesson to be learned from safety-critical systems which can be applied to the management of dependable computing: to gain assura...

Run-time trace data helps to debug and analyze the parallel programs. Obtaining and managing this data during run-time is the responsibility of an instrumentation system that incurs overhead. In its worst case, this overhead can result in severe perturbation of the behavior of the actual program. This paper presents a queuing model for an instrumentation system. The purpose is to provide a rigo...
