Performance evaluation of telecommunications
I have been interested in
phenomena related to correlation in telecommunications networks. The first
problem is that of the correlation between the loss process of consecutive
packets. Assume that N consecutive packets are considered to constitute one
message. Then the loss probability of a message cannot simply be calculated
through the loss probabilities of individual packets, since these losses are
not independent. We propose several models to we calculate these probabilities explicitly.
This is a starting point for the analysis of the effect of adding redundant
packets to messages, which allows to reconstruct losses. Other problems in
which we need to compute the loss probabilities of messages arise in message
discarding policies (early discard, partial or selective discard). Another type
of problem we study is the delay of a message that contains N packets. This
again cannot be calculated from the delay of single packets, and require an
analysis based on multi-dimensional (PGF).

losses and on forward error corrections:
