This quantity of the Lecture Notes in computing device technology sequence includes the entire papersacceptedforpresentationatthe16thIFIP/IEEEInternationalWorkshop on allotted platforms: Operations and administration (DSOM 2005), which was once held on the collage Polit` ecnica de Catalunya, Barcelona in the course of October 24– 26, 2005. DSOM 2005 used to be the 16th workshop in a sequence of annual workshop and it the footsteps of hugely profitable earlier conferences, the main - cent of that have been held in Davis, united states (DSOM 2004), Heidelberg, Germany (DSOM 2003), Montreal, Canada (DSOM 2002), Nancy, France (DSOM 2001), and Austin, united states (DSOM 2000). The target of the DSOM workshop is to deliver togetherresearchersintheareasofnetworks,systems,andservicesmanagement, from either and academia, to debate contemporary advances and foster destiny development during this ?eld. not like the bigger administration symposia, akin to IM (Integrated administration) and NOMS (Network Operations and administration Symposium), the DSOM workshops are geared up as single-track courses so as to stimulate interplay between participants.

Formal tools were proven because the rigorous engineering technique for the approach improvement. making use of formal the way to a wide and intricate method improvement frequently calls for the modelling of other features of this kind of procedure. for example, complicated structures (such as built-in avionics structures, engine keep an eye on software program) can contain practical and timing standards that needs to be finally carried out as executing code on a speaking dispensed topology.

Sample text

Table 1 displays a non exhaustive list of management profiles and factors that affect the performance of a managed system. Within these profiles, three parameters are chosen and studied in more details in the paper. For each parameter, the intuitive impact on the performance of the managed system is listed. 1 Management Tasks As defined in [10], management system tasks are the following: – Monitoring: the ability to capture runtime and historical events from a particular component. This task is continuous over the execution time of the managed system and it is executed concurrently with users on each monitoring cycle.

These two techniques are more flexible [13] than the measurement technique and they can handle a wide variety of configurations of the managed system by varying the impact factor and management profiles. Their disadvantage is that they need the availability of analytical models both for the managed system and the management one. It is not easy to obtain them for complex distributed systems. We define the following steps to calculate the impact function. We first determine the baseline performance of the target system.

This task is executed less frequently than the monitoring on a period from the execution time of multiple components within the managed system.
