  **** MetroGrid workshop : Metrology for Grid Networks ****

within the framework of GridNets 2007 International Conference October
17, 2007, Lyon (France) http://gridnets.org/2007/MetroGrid-WS.html 

Keywords: computing grids, metrology, traffic, statistical inference,
signal processing, stochastic modeling, heavy tail distributions, long
range dependence, self-similarity, non-stationarity.

The constantly increasing interest devoted to grids, both in terms of
developments and applications, proves that distributed computing has now
attained a sufficient degree of maturity to be considered as a new
network paradigm on its own. As a result, it becomes more and more
unrealistic to simply transpose to grid contexts, existing mechanisms
that were initially thought and developed for different platforms. Grids
specificities, such as the cooperating equipments number and
heterogeneity, the number of independent processes, the treatments,
bandwidth and stock capacities, advocate to revisit the algorithms, as
well as the control and operating mechanisms, in order to reach optimal
performances. But to succeed, a full comprehension of the dynamics that
underly the interacting processes is a prerequisite for tailoring
adapted exchange and routing strategies.
The same need arose in wide area networks (Internet), that prompted the
development of a dedicated metrology activity, leading researchers to
resort to statistical analysis and to stochastic modeling of the traffic
flows to match versatile theoretical processes. However, nothing
guarantees that these models remain valid in a computing grid
infrastructure, nor it is proved that traffic flows in grids present the
same statistical properties as the ones evidenced with Internet.

The workshop will open with two tutorials aimed to sketch a state of the
art in metrology, and to highlight similarities and differences between
standard (Internet) and grid networks.

MetroGrid workshop solicits papers that address all ingredients of a
treatment chain, encompassing:

- Metrics and Measurements issues
 	o definition of sensible metrics
 	o measuring level (TCP, IP, packet, flow,...)
 	o sampling rates and sub-sampling
- Technical considerations
 	o importance of grid topology
 	o instrumentation for acquisition
 	o experimental setups and scenarios
- Data processing
 	o time series analysis (LRD, self-similarity, stationarity
assessment,...)
 	o statistical inference (Markov models, heavy tail distribution
estimation,...)
 	o stochastic modeling (multi-fractals, goodness-of-fit,...)
- Impacts on performances
 	o quality of service
 	o resource management
 	o robustness and resilience issues


Accepted papers will be published in the GridNets 2007 conference
proceedings.
Proceedings will be published by ACM and will be available through ACM
Digital Library. Papers must be submitted in electronic format following
