L'indiseernabilite locale dans les reseaux de files d'attente a multiliaisons ou multiserveurs

摘要

As previously for single link queueing networks, now it is proved, for multiserver (multi-link) queueing networks, that the local queues are defined by indistinguishable local arrivals (after having crossed two or three stages), corresponding (in buffers) to some agglutinations of short service times behind long service times, possibly leading (in the input buffers) to very Jong congestion times (even for low traffic intensities) when the service times are highly varying. In that case, traditional queueing theories (mainly influenced by the loads) are not appropriate for input buffer dimensioning.
