2016 2016 IEEE NetSoft Conference and Workshops (NetSoft)  
ACKNOWLEDGMENTS This work is partly funded by the French ANR under the ANR-14-CE28-0019 REFLEXION project  ...  This finer granularity allows diagnosing until inner component level. The dependency graphs of network resources (Fig. 3 ) describe their internal components and their dependencies among them.  ...  In addition, the finer granularity of the proposed templates details the states of the components inside the networked nodes and details the state of the VNFIs embedded in the hosts.  ...

UML Specification of a Generic Model for Fault Diagnosis of Telecommunication Networks [chapter]

A. Aghasaryan, C. Jard, J. Thomas
2004 Lecture Notes in Computer Science  
this document presents a generic model capturing the essential structural and behavioral characteristics of network components in the light of fault management.  ...  The generic model is described by means of UML notations, namely class diagrams, sequence diagrams and instance diagrams. The model covers both circuit-based and packet-based networks.  ...  The generic model captures the essential structural (generic components and their relations) and behavioral (interactions between the generic components) characteristics of telecommunications network components  ...

The contact tracing network involved 58 components with low overall density (1.2% statewide); 33% of firstdegree contacts could not be located.  ...  Four clusters connected network components that were not linked in contact tracing. The largest component (n=28 cases) included two distinct phylogenetic clusters and spanned two regions.  ...  The content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institutes of Health.  ...

Y. PENCOLÉ, M.-O. CORDIER, L. ROZÉ
2002 International journal on artificial intelligence tools  
We address the problem of diagnosing complex discreteevent systems such as telecommunication networks 1 .  ...  In particular, if no interaction with other components are claimed in those trajectories, then " § ¦ " ¨represents all the trajectories of ¢ and © which explain the whole set of observations .  ...  The main weakness of the first approach is the lack of genericity, as the network changes, a new expertise has to be acquired.  ...
