Dependability of IP networks
This web site was established by the Finnish research project
"Dependability evaluation methods for IP networks", IPLU (IP-verkkojen
luotettavuuden arviointimenetelmät). The IPLU project aimed to
create a conceptual framework for assessing the complex
problem "Can one rely on IP technology?" The project started in
November 2005 and lasted for one year. The follow-up project IPLU-II (2007-2008) is part of Tekes'
GIGA program. This
page informs about results and events of both projects.

Other material:
Dependability case of Funet's core
network:
The
first testing of dependability case methodology on Funet's core
network. This is not ment to be a proper dependability assessment, but
we have attempted to consider all relevant aspects and formulate
respective subclaims and argumentation that could be found to support
them. This prelimanary case points to a way how to proceed
towards a more thorough investigation (with more hard data available).
The dependability case methodology itself is described in
the paper "A Dependability Case Approach to the Assessment of IP
Networks", see above. html-version of the
dependability case
A talk on the Dependability
Case of Funet's Core Network given in NORDUnet 2008 conference.
