Abstract :
A method is presented to compute a fundamental traffic engineering parameter, the end-to-end blocking probability, when both traffic and reliability aspects are taken into account. Additionally, link failures are not assumed independent. This situation is justified by the practical scenario of logical network, even if the physical link failures are independent, after mapping the failures into the logical network, the logical links do not fail independently. Dependent link failures can also occur as a result of a node failure.
